With Adhesive Tape Packaging of Vegetables and Fruits Formaldehyde Exceeded 10 Times

People often go to the supermarket to buy food may be found that a lot of fresh vegetables are wrapped in colorful tape, in this regard, some news reported that the packaging of vegetables formaldehyde exceeded 10 times!

Adhesive Tape Packaging of Vegetables

Experts pointed out that part of the supermarket used basic industrial tape to pack the food, this tape containing benzene, formaldehyde, heavy metals and other harmful substances. Therefore, he suggested that consumers try to peel and cut off, or remove the the fruit or vegetables by direct contact tape.

Many vegetables in a supermarket District sell spinach found that Chinese cabbage, cucumber and other vegetables, are packed by purple or green tape,some price tag directly attached on the vegetables.

With adhesive tape bundled vegetables, fruit phenomenon is very common, it is mainly for the convenience of customers to choose and buy, looks more beautiful and tidy.

Industrial tape containing benzene, formaldehyde, heavy metals and other harmful substances, not suitable for food packaging materials, in addition to the surface of the tape printing ink benzene substances through the skin of vegetables vegetables to the interior of the migration, the gum base portion of the plastic itself often contains a plasticizer.

We make a test on these kind of vegetables, results show that, contact with the tape of  some vegetables formaldehyde actually exceeded ten times. Therefore, the expert points out, long-term consumption of these fruits and vegetables, will produce toxic side effects of digestive system and liver and kidney function.

So when buying vegetables and fruits, it is suggested that not to buy the packing one or remove the one which contacted by this kind of tape. And we remmend you to use nitrate tester to test the food is safe or not before cooking them.

4 Tips to Avoid Nitrate in Vegetable and Fruit

Vegetables and fruits are indispensable in our daily life, but if we don’t pay attention edible health, they will bring harm to our body healthy. Especially in hot summer, it will bring diseases if we eat the unsafe vegetable and fruit. And here for all of you, we conclude five tips on how to eat vegetable and fruits in healthy way.

1. Prevent Intestinal Pathogenic Bacteria and Parasite Contamination

Farmers use chemical fertilizers, farmyard manure etc when growing the plants. The bacteria and parasites on the fertilizers still has strong vitality on the plants. Most of these arvested vegetables and fruit are on the market without washing. We can often see cabbage, spinach and other residual stool trace or with a bad smell on the vegetables. Therefore, it is strong recommend washing raw fruitsand vegetables before eating in canse we may cause intestinal infectious diseases.


Epidemiological investigation confirmed that the disease is spread by the unhealthy vegetables, fruits . Now many people are afraid of  fertilizer growing vegetable and like organic vegetables. We must wash vegetables thoroughly before cooking, general after cleaning the bacteria can reduce less about 80%.And here are some tips on how to eat vegetable and fruit healthy.

2. Prevent deterioration of the decay and excessive intake of nitrite

Fresh fruits and vegetables contain a certain amount of nitrate and nitrite, after storing for a period of time, water evaporation after the dry, under the action of microorganisms and nitrate conversion to nitrite. If the vegetables, the fruit epidermis have been damaged, canker, microorganism was easy to invade the, vegetable, nitrite content in fruit increased.Dry and deterioration of fruits and vegetables, whether human or animals after eating can occur nitrite poisoning. Not only that, if the food deterioration due to containing amines, it will produce strong carcinogens – nitrosamines, on the human body have potential hazards.


3.Prevent Pollution of Vegetables Caused by Sewage Irrigation

Sewage mainly refers to the discharge of industrial waste water and domestic water, industrial wastewater containing many kinds of toxic chemicals, such as phenols, cyanide, heavy metals, sewage often contain a large number of eggs and various pathogenic bacteria and various washing supplies a variety of harmful chemical substances, the water if not through the sound processing, it is used to as irrigation water, not only affects the growth of vegetables, but also to eat healthy harm.

Therefore, in the choice of vegetables, as far as possible to choose elevated crops, such as tomato, bean, cucumber and smooth surface of vegetables such as eggplant, pepper and so on to reduce pollution. To put vegetables should pay attention to choose without spot, no rust rot traces, vegetables fresh luster, after thoroughly cooked. If you want to some raw vegetables and fruits, preferably with light saline soak a few minutes the safest.


4. Prevent Pesticide Pollution

Pesticide contamination of food, there are many ways, but the most direct pollution is sprayed. Therefore, pesticide pollution of vegetables, fruits, on the surface of pesticide residual quantity highest, if you do not pay attention, often make a person anxious chronic poisoning. Family organic phosphorus pesticide poisoning have been reported.


In the purchase of food,be carefully, especially vegetables, leafy vegetables), if the surface is white or yellow spots of the dishes do not buy, because they may be immediately after spraying pesticides after picking, pesticide residue high amount. Buy vegetables best water fully after cleaning, then soak for a few minutes or longer time. By cleaning can greatly reduce the amount of pesticide residues in vegetables. The underground stem or vegetables such as potatoes and cucumbers, use a soft brush fully cleaned.

The pesticide residues are high in the surface of the fruit, for the sake of safety, or peeling as well.

At last, it is recommend we use Greentest nitrate tester to check the fruit and vegetable is safe or not before eating.



3 Criteria for The Health of Children’s Diet

As a parent, you know kids about healthy eating There criteria?? margarine, cake, cookies, chips and other food in a large number of trans fatty acids, sweets, desserts, sweet drinks “quick release” sugar, carbonated drinks, fruit juice, preserved fruit, soy sauce with benzoic acid as preservatives, there are a lot of artificial synthetic pigment. The more bright enough in the taste of the food, more is the enemy of the healthy growth of children.


1. Should not eat colorful food preservatives and pigments children must be avoided.

There are many kinds of preservatives, some of which may be caused by allergies, loss of appetite, growth retardation; serious, long-term consumption may even lead to liver, kidney function is damaged or carcinogenic. Such as benzoic acid, although it is legal food additives, but excessive or long-term intake may affect liver function. Carbonated drinks, fruit juice, preserved fruit, soy sauce used benzoic acid as preservatives. Artificial synthetic pigment may cause the child hyperactivity, learning disabilities.

2. Beware of high oil food

Excess fat, not only easily lead to obesity, causing many chronic diseases, causing cell disease, affect the reproductive capacity. In addition, more need to pay attention to is trans fatty acids. This fat will not only increase the risk of cardiovascular disease, and diabetes, colorectal cancer. Australian research discovery, trans fat will also affect the child’s IQ, common in margarine, cake, cookies, chips and so on. Let the children eat greasy food, such as cream cakes, cookies, fried chicken, and so on.

3.Refuse to carcinogenic Food

Improper diet food, may let the child at the risk of cancer, so let the child eat carcinogenic food. The nitrite and aflatoxin is easy to eat carcinogens, to be especially careful. Taiwan Chang Gung Memorial Hospital Director of clinical toxicology Department Lin Jieliang pointed out that many the study found that children once a week to eat more ham, bacon, sausage, Bacon, hot dogs and other food containing nitrite, leukemia could increase the risk of aflatoxin 70%. may induce liver cancer, in humid climate, improper storage of peanuts, corn, and other cereals, are easy to produce. And nowaday, there are many fruits and vegetables are not so organic and there are full of harmful substance inside because the large amount of fertilizers. So it is esential to check nitrate lever with nitrate tester to make sure the food are safe to your kids.

Four Kinds of Plants for you to Block Radiation

In our daily life, we use mobile phone or iPad  or some other domestic appliance which can raise the radiation level in our living around. Radiation can be appear everywhere in our life, household appliances have radiation, even if it is in a closed state. And research shows that large amount of radiation in our around can do harm to our healthy. You may wondering how much radiation arround you, and how to block radiation? 

A new product Greentest radiation detector can help you determine the radiation level arround you and show you if you are in a healthy living envirenment.


How to prevent and reduce the radiation attack? There are four kinds of green plantsfor you to block the radiation hazards.

Cactus or cactus

Cactus or cactus

cactus or cactus is courtyard greening and beautifying of fine varieties of flowers, though they covered with thorns, but the shape is beautiful available to processing is used as medicine and food, but also has absorption of electromagnetic wave radiation, reduce computer endanger human health “specific function”. Cactus body a sting, thick meat, containing water, easy to absorb and dissolve the ambient electromagnetic field radiation and toxins, reduce indoor pollution, beneficial to human health.



Its meat containing glial crude fiber, can Runchang, detoxification, can absorb harmful substances within the intestinal excreted in the stool. Because it has the effect, so any radiation. It can absorb, placed beside the computer is very good, and it is tropical plants are drought tolerant, keep a lazy group on the best, however, ten days eight days not drench water no problem.



Sansevieria alias Sansevieria, Liliaceae, smell is the smell of sweet and elegant, it on the environment adaptability is a “gritty” plant, not only can detox, still can release a large amount of oxygen, the ability to absorb radiation is also very strong. In the computer next to Meimei put a basin, absolutely let you comfortable hundredfold!

This most common plant is not only a good one, but it can also beautify the environment, purify the air, and it is also a good product for radiation protection. It also can inhibit the release of xylene and toluene from computer monitors and printers.



Four seasons of fresh green Chlorophytum, sewage suction “ace”. “Home grown Chlorophytum, and the evil spirits appalled, south of Fujian, Taiwan people on its ceiling dirty ability to give a high evaluation.


How to Measure Radioactivity

As we all know that exporsure to rediation can do harmful to our body healthy,but in our daily living environment, it may be found any where. Some of materials and products sitting around your house could be emitting low levels of radiation, so how to make sure your living environment radiation level are safe.So how is radioactivity measured?


Are Radiation Can be Test?

It’s sure that Radiation can be determine. There are different units of measurement for radioactivity depending on what is being measured. In addition, the term used varies depending on whether conventional units are being used – the curie, the rad and the rem – or you’re relying on the system internationale (SI) units – the becquerel, the sievert and the gray.

What is the difference between these units of measurement? The rad or the gray are used to measure radiation a person takes in, and the rem or the sievert are used to understand how much risk people have by being around a source of radiation. Additional measurements include counts per minute and counts per second, which are useful for measuring alpha and beta particles. You can then measure this radiation that’s given off from radioactive materials.

How to measure Radiation

As the above taking, we can test the radiation around us, we have the ability of measuring radioactivity with the right tool. You can use a radiation Tester or a similar radioactivity measurement device to measure the radiation levels in your own home and other environments where you spend time.

The Greentest Radiaton detector has gas within its tube that is ionized by radiation when it’s present. The meter can detect different kinds of radiation, including beta, X-rays, alpha and gamma radiation. It can help you figure out the radiation in your environment, and then there are also EMF meters that tell you how much electromagnetic radiation from technology you’re exposed to and devices that test the radiation levels in your food. The measurement types, such as counts per minute and sieverts, can vary depending on the specific device you are using.

Overall, it’s easy to measure radioactivity from your own home when you have a measuring device. You’ll quickly get the hang of the particular meter you choice and how it measures and reports radioactivity.




Easy Ways to Remove Pesticides From Fruits and Vegetables

As we all know that, farmers used pesticides and fertilizers for the corps and pesticides might be present in fruits and vegetables we eat. And many experiment testing on fruits and vegetables and found unacceptably high amounts of pesticide residue in them. What cause the the problem is:  High levels of pesticide residues can be toxic enough to cause long-term cancer, damage to the nervous and reproductive systems, birth defects, and severe disruption of the immune system.

For our healthy eating and care our family diet healthy,  you should be extremely careful of what you buy and where you buy fresh food from. You should also take certain measures to minimize any kind of health damage. Here are three simple to do to make sure the fruits and vegetables you buy are safe and health to eay.

Wash them Clearly and  Wash it Right

Wash all your fruits and vegetables after buying from the market,  2% of salt water will remove most of the contact pesticide residues that normally appear on the surface of the vegetables and fruits. Most of pesticide residues are removed by cold water washing. Also, be more thorough with these fruits and vegetables in specific: grapes, apples, guava, plums, mangoes, peaches and pears and vegetables like tomatoes, brinjal and okra as they might carry more residue in their crevices.


Vinegar Soak

Whip up a solution with 10 percent white vinegar and 90 percent water and soak your veggies and fruits in them. Stir them around and rinse thoroughly. Be careful while washing fruits like berries, and those with a thin peel as the solution might damage their porous outer-skin.

Blanch and Peel

Treat your vegetables to warm water for a short while and this should remove any leftover residue. Peeling is another efficient way to remove residue and comes highly recommended especially when there might be some residue in the crevices of the fruit. Also, when cooking with chicken or meat, cut off the excess fat and skin as it could have absorbed unwanted pesticide residue.

Use Greentest Food Safe Test Kit to Check the Nitrate and Pesticide

Besides the above tips on remove pesticides, here is a simple trick to help you when buying vegetable and fruits. If you are not sure they are safe and organic, some food safe test kit can help you test the nitrate and pesticides level of the food, it will show you whether the food are safe or not.

Test Food Safe Before What you Eat

Most food when growing are treated with pesticides at least a few times. Pesticides enable farmers to produce some crops in areas that otherwise would not be suitable, increase crop yields, preserve product quality, and extend shelf life. And this would cause the problem – if the food would safe to eat.

Many of us may need to buy these fresh food from market everyday, while you may think that you are helping your family stay healthy by opting for fresh foods, these foods may actually be more harmful than they are good for you. Produce is often grown with the use of pesticides. These chemicals are designed to kill pests and not only sensically pose a danger to you and your family, but are scientifically proven to. By identifying foods that are most commonly grown with high levels of pesticides, you can avoid having to resort to these conventionally-grown options. Here are the 9 foods that are infamous for testing positive for large amounts of pesticides.

• Apples
There is nothing like plucking a fresh apple from the tree and taking a bite, but these fruits have tested positive for over 30 different known pesticides! Farmers may spray apple trees with pesticides as many as 10 times during the growing process, making 99% of apples test positive for at least one pesticide residue.

• Strawberries
These delicious fruits are packed with pesticides. Conventionally-grown strawberries are susceptible to fungus, so to prevent fungus growth they can contain as many as 65 different pesticides. These fruits are grown with chemical fertilizers that are designed not only to kill fungus but also eliminate hormone disruptors, carcinogens, neurotoxins and more.

• Blueberries
Testing positive for more than 50 pesticides, the thin layer of skin on blueberries allows chemicals to easily contaminate the fruit. Even though the antioxidants in blueberries are excellent for your family’s health, a single sample tested positive for 13 pesticides! The multitude of pesticides are linked to an array of human health hazards, such as cancer, hormonal issues, neurological disorders and more.

• Lettuce
The worst chemicals used on lettuce include fungicides, carcinogens and neurotoxins. The delicate nature of lettuce makes it more susceptible to decay and fungus, so toxic chemicals are often sprayed on the vegetable to inhibit mold growth. Lettuce typically tests positive for 50 chemicals – so always make sure you wash the lettuce you bring home!

• Peaches
The sweetness of peaches attracts a wide variety of pests, so conventional farmers offset this issue by using toxic chemicals. Endosulfan, a potent pesticide that has been linked to birth defects, is the most commonly used pesticide for peaches. Peaches contain more than 60 pesticides, so they must be washed completely before you give them to your family.

• Hot Peppers
Hot peppers are of special concern for public health because they have been found laced with particularly toxic pesticides including organophosphate and carbamate insecticides. These are chemicals that are no longer widely detected on other produce, either because of legal restrictions or voluntary phase-outs. If you can’t buy organic hot peppers, cooking them will typically diminish pesticide levels as well.

• Tomatoes
Tomatoes, particularly cherry tomatoes, are susceptible to about 30 different diseases, so growers use pesticides as an easy way to protect these plants. Because their protective layer of skin is so thin, tomatoes test positive for over 60 different pesticides that can danger your family’s health.

• Bell Peppers
Peppers are sprayed with a combination of up to 50 different pesticides. Farmers often use methyl bromide during the growing process to protect their crop. A potent paraquat is often used on peppers, and this type of pesticide is more toxic than others. No matter the color of bell pepper, this fruit always has a high pesticide residue.

• Potatoes
While potatoes are America’s favorite vegetable, over 35 pesticides have been detected in potatoes by the USDA. That is partly due to the fact that a chemical treatment is used in potato fields before eyes are planted. Farmers also use pesticides on the first sprouts that crop up to prevent pests from eating potato plants before they grow.

Wash your foods or how strictly you buy organic products, it can’t not really clear the pesticide inside the food,  by using the Greentest food tester, you can measure the level of pesticides found in the food you give your family. Because pesticides can be linked to birth defects, cancer, neurologic and endocrine system disorders, particularly in children, testing for pesticides (Nitrate) is extremely important.

How to Test Pesticides in Vegetables

As nowadays, farmers use large amout of fertilizers and pesticides to grow the plant so they can grow fast and look more beautiful than ever before. Thus cause many problems in the vegetables, too much harmful subtances inside which can do harm to our body if intake too much.


So more concerned about their food supply than ever before, Many scientists have developed an increasing interest in whether pesticides can be found in their vegetables, as well as in organic foods. They strives to keep the food supply safe by setting limits on pesticide use on crops. Unfortunately, methods of testing vegetables for pesticides require cost-prohibitive and sophisticated laboratory equipment. However, you can minimize your exposure to pesticides in vegetables by choosing and preparing foods carefully.

Independent testing laboratories offer testing for pesticide residues in plant tissues. Plant material must be handled carefully and frozen as quickly as possible to prevent chemicals from being metabolized. They must then be shipped on ice to a lab. This kind of testing is only useful for vegetables that can be destroyed. It is also cost prohibitive, as testing starts around $100 per sample for a single contaminant. Many labs test only for suspected chemicals rather than generating a list of chemicals found in the plant materials. Laboratory testing is not a practical option for anyone except the commercial farmer.

Further minimize pesticide exposure by carefully preparing vegetables that may contain residual chemicals. Scrub vegetables under running water, but do not use soap. Peel vegetables to remove any surface contaminants that may remain. Discard the outer leaves from cabbage and lettuce. Cooking can also break down residual pesticides that may have absorbed into the vegetable in trace amounts.

Simple way to test Pesticides in Vegetables

A simple and quick way to test pesticides when you buy vegetables is to use chemical test kit. Pesticides can cause a large amout of nitrate in vegetables, so you can use Greentest nitrate tester to test the nitrate level to determind wether the vegetables is safe to eay.


  1. Choose vegetable category you want to test.
  2. Insert the probe and press start test.
  3. Get results in 3 seconds, it will show you whether the vegetable is safe or unsafe to eat.


Talking About Nitrates in Vegetables

Heavy applications of nitrogen fertilizer can cause nitrates to accumulate in vegetables

Vegetables are a high-value crop. Farmers tend to apply large amounts of fertilizers, especially nitrogen. This is a reasonable insurance against yield losses from nutrient deficiencies, especially if fertilizers are fairly cheap. However, applying too much nitrogen fertilizer may be bad for human health.


Nitrates are nitrogen-oxygen chemical units which combine with various organic and inorganic compounds. Once taken into the body, nitrates may be converted into nitrites. Crops containing high levels of nitrates can be identified by laboratory tests. However, they appear normal to the eye. Nitrates in vegetables and fruit have no taste or smell.

Nitrates occur naturally in fruit and vegetables, but only in small quantities. They can rise to high levels in intensively grown crops. Organic vegetables are no safer than conventional crops, in this respect. As far as nitrates are concerned, it makes no difference whether the nitrogen comes from compost or from chemical fertilizers. Organic vegetables sometimes receive more than thirty tons of compost a year, and may contain high levels of nitrate.

There is a strong relationship between the amount of nitrogen applied to the crop, and the level of nitrates in the plant. Nitrate levels are also affected by the season, and even the time of the day. There is some evidence that nitrate levels in produce are very high in countries with a cold climate, where most vegetables are grown under structures.

High levels of nitrate in food or drinking water are known to be dangerous to babies in the first three months of life. They cause the blood to carry less oxygen, and the infant may suffocate. Older children and adults are not affected in this way. However, the prolonged intake of high levels of nitrate is linked to gastric problems, due to the formation of nitrosamines/.

Such compounds have been found to cause cancer in animals. The same may be true of human beings. Of particular concern is the possible link between fruit and vegetables with a high nitrate content, and cancer of the gullet. A current study in Scotland is examining the possibility that human saliva may be converting nitrates into carcinogens, which come into force at the gastro-oesphageal junction.


If nitrate levels in vegetables are too high, growers must reduce the amount of nitrogen fertilizer they apply. The problem from the grower’s point of view is that reducing nitrogen applications is likely to give lower yields. If growing healthy crops involves some sacrifice of yield, we are faced with the question of who will pay the cost of this.

Greentest is a portable nitrate tester for vegetables, it can help you test the nitrate level of your food before eating. Intaking too much nitrate can do harm to our body, it is eseential to make sure your food is safe with Greentest.
