How to Detect the Nitrate and Nitrite in Vegetables and Fruits

People’s requirements for food quality as standard of living rise ceaselessly and improve, in recent years, people’s food safety and quality problems have extensive attention. Nearly half a century, the rapid development of industrialization led to the chemical fertilizer production, greenhouse cultivation, hydroponics and soilless cultivation technique in vegetable, fruit production widely used.


Some vegetable growers in the pursuit of economic benefits, blindly use or misuse of these technologies, ignoring the vegetables and fruit nutrition quality breeding and comprehensive cultivation technique, resulting in vegetables, fruit safety quality serious decline.

Vegetable research, the residues of fruit nitrate and nitrite and other harmful substances, in the production, storage, processing and distribution in the process of detecting, monitoring and analyzing method and to provide a scientific and accurate, timely, impartial inspection data and means, strictly control the quality and safety of vegetables listed, to protect the interests of consumers and health are essential.

At present, there are many methods for the determination of nitrate and nitrite in vegetable samples. According to the different principles of measurement, there are three main kinds of methods, such as spectroscopy, electrochemical method, chromatography and so on.

Ways to detect Nitrate and Nitrite in Vegetables and Fruits

Laboratory Test:

1 instruments and reagents

(1) the main experimental instruments: (sk2510hp kudos); high speed centrifuge; electronic balance (fa2004); 0.45 m filter.

(2) reagent: nitrate standard solution (with n), concentration: 9 mg/l; nitrite standard solution (with n), concentration: 0.509 mg/l; 0.01 mol/l sodium hydroxide solution, activated carbon, ultra pure water and so on.

(3) samples: cucumber, cabbage, lettuce, green orange, pear, banana, Cherry Tomatoes and other seven kinds.

2 sample treatment

(1) sample: take fresh vegetables or fruit samples of about 10 g (accurate to 0.0001 g) in a mortar, grinding into homogenate.

(2) in 50 mL concentration is 0.01 mol / L NaOH solution the homogenate wash in a conical flask cover.

(3) ultrasonic extraction: 10 min under the conditions of ultrasonic extraction, static.

(4) centrifugal separation: pour the supernatant in a centrifuge tube, in speed under the conditions of 11000r/min centrifugal separation adsorption for 10 min.

(5): after centrifugation, the supernatant in the inverted in a small beaker, add the right amount of activated carbon to adsorb organic compounds in the extract, separation, colorless and transparent liquid.

(6) filter: after a 0.45 m filter collected in 5 ml into tube like, to be determined.

3 analysis method

IonPac as9-hc 4 mm of anionic analytical column, IonPac ag9-hc 4mm anion protective column eluent: 10.00 mmol / L KOH; flow rate of eluent: 1.00 ml / min; sample volume: 25 UG / L.

Portable chemical test tool

Another easy way is to use nitrate tester, this kind of tool can easily test the nitrate level in fruits and vegetables and fresh meat in 3 seconds, it is quite useful for us when buying vegetables in the market, test the samples before buying is a useful way to protect our family healthy eating.


Steps to use Greentest Nitrate Tester:

1.Choose the fruit/vegetables category you need to test.

Not to Drink Processed Fruits and Vegetables Beverge


As we all know that, fruits and vegetables are good to our body healthy, and eat them every day can keep our body. Espercially fresh vegetables and fruit is very helpful for our body to remove the toxins.  But we may see that there are many drinks on the market which made by processed fruit and vegetable,  the effect of these kinds of drink is just the opposite, it will affect the discharge of toxic substances.

Fruit and vegetable juices in the process lost a lot of dietary fiber, dietary fiber to maintain a healthy digestive system is very important, in the prevention of cardiovascular disease, cancer, diabetes and other diseases can also be diluted and accelerate gastrointestinal carcinogenic compounds and toxic substances discharged. While missing less dietary fiber in fruit and vegetable juices instead will affect the discharge of toxic substances.



How many pesticide residues on the fruit

According to the U.S. Department of agriculture, food and Drug Administration in 2000~2009 years up to 5100 times of cleaning, peeling test, get some specific data. For example, after washing an apple, the pesticide residue ratio was 97.8%.

The United States Department of agriculture (USDA) a pesticide data program is a year of vegetables and fruits of pesticide residues, from 1991 began. The project, the annual inspection of the sample volume from the original more than 7000, to more than 1 million in 2000 and increased year by year.


PDP detection of pesticide residues is to assess the amount of the American diet intake of pesticide, rather than to determine whether qualified food. Can detect pesticide residues are closely related with the detection technology. Detect residual doesn’t mean the food is harmful to our health. Rumors are listed in the “pesticide hazards” does exist, but left the dose about harm completely pointless. We need to pay attention to is: Pesticide Residues in fruits and vegetables, bring much risk?

In the United States, the Environmental Protection Agency (EPA) to a variety of pesticides in food residues established limits. According to the definition of limit, no more than this standard of pesticide residues, the health risks can be ignored. If the PDP detection value exceeds the standard limit, or to detect the EPA has not yet of standard of pesticide, the PDP will be informed to the food and Drug Administration (FDA).

As mentioned before, detected pesticide residues is not the same as the ranking of health risk.Ewg completely ignore this factor, with a “you” and “no” or “more” and “little” such a simple classification, and can not objectively reflect real situation of pesticide residues in these fruits and vegetables and health.

So it is highly suggested that you should clean your fruits before eating, if possible, use Greentest nitrate tester to test whether is unsafe substance level is under the healthy control.

Harm of Pesticide Residue and its Detection Method

Pesticides in food, vegetables, fruits, fish, shrimp, meat, eggs, milk, causing food pollution, can do harm to people’s health.

General organic chlorine pesticide metabolism in the human body is very slow, long accumulated time. Organic chlorine in the human body remains mainly concentrated in the fat.  Such as DDT in the human blood, brain, liver and adipose tissue in the proportion of 1:4:30:300; Di agent for 1:5:30:150.

Because pesticide residues are very harmful to human and biological, all countries have strict management of pesticide application, and the amount of pesticide residues in food is regulated. Such as Japanese pesticide registration system, once confirmed that some pesticides harmful to people and animals, the government will restrict or prohibit the sale and use.

For the detection of pesticide residues, we have used in conjunction with professional residual pesticide test instrument to detect, to governments at all levels of vegetables testing center, bazaars, supermarkets, environmental protection, vegetable planting base of hotel and other units of pesticides in vegetables and fruits by strict residue determination.
