The incidents of Sudan red, hair soy sauce, lean meat, poisonous rice and waste oil that have been exposed in the past two years have caused Chinese people to think about China's food safety issues. At present, food safety faces the problem of pesticide residues in fruits and vegetables, and has reached the point where the relevant departments attach great importance to it.
The Ministry of Agriculture once investigated pesticide residues in agricultural and livestock products in 24 provinces and cities across the country. The results showed that vegetables and eggs were the most polluted, with residual ratios of 33.1% and 22.15%, respectively. The average annual use of pesticides in China is about 500,000 tons, of which 30% is absorbed by crops and 350,000 tons are flowing into rivers and enter the human food chain. There are also various additives added during the food processing process, which are chemicals that are extremely harmful to the human body.
In recent years, agricultural products poisoning incidents and export inspections have been blocked and reported to be reported frequently. The survey shows that for field crops, 30-50% of the crops are lost without pesticides. For economic crops like vegetables and fruits, pesticides are not used, and the loss rate of agricultural products is 40-80%. Therefore, pesticides are commonly used in rural areas to increase crop yields. These are the reasons for the large amount of pesticide residues in fruits and vegetables.
Residues of fruits and vegetables can cause acute and chronic poisoning to the human body, leading to cancer, deformity and mutation. In order to avoid these hazards, people usually use the following methods for simple disinfection: such as water soaking, alkaline water soaking, high temperature treatment, detergent cleaning, sunlight, but these methods are not ideal for removing pesticide residues from fruits and vegetables. . According to research, boiling water scouring will lead to more than 50% of nutrient loss. The use of disinfectants is likely to cause secondary pollution, and the effect of sunlight exposure is not obvious.
Professor Zhu Songchun, former chief engineer of the Chinese Academy of Military Sciences, China Association of Public Welfare, and chief adviser of the China Love Engineering Committee, pointed out that the daily cleaning method of vegetables and fruits has only a slight effect on the removal of pesticide residues in food.
When buying fruits and vegetables, it is really important to distinguish whether there are pesticide residues. Therefore, all major markets have pesticide residue testers, which are measured on the spot for consumers to buy and rest assured.
Pesticide residue rapid tester can be widely used in product quality supervision and inspection, health and epidemic prevention, environmental protection, business management, vegetable wholesale market, vegetable production base, supermarkets, shopping malls, pesticide residue monitoring systems and other departments of pesticide residues in vegetables and fruits
