Establishing a unified food and drug regulatory system “Additives are an important aspect of food safety issues. Although the state has strict regulations regarding the types and amounts of food additives, a series of problems may arise during the actual operation process. The abuse of additives is a more serious phenomenon.†Xu Jin said in his speech that the state has explicitly prescribed 33 kinds of preservatives. There is an upper limit for the amount of each additive, but some businesses may extend the sales cycle of products, even if they do not add Adding one additive at a time, but adding several additives at the same time, results in the abuse of food additives. In addition, the production of some food additives is only a by-product of some manufacturers, failing to meet relevant standards.
Xu Jin also believes that multi-headed management is one of the important causes of food and drug safety problems. According to reports, China's food standards are set by the Ministry of Health, and the industrial and commercial bureaus and food and drug administrations carry out market management. Each department has a division of work according to functions. In the specific implementation process, it is inevitable that there will be poor communication and thus emerged. Problems such as lack of supervision and law enforcement.
In this regard, Xu Jin suggested that the state should establish a unified national food and drug supervision system as soon as possible to solve the long-standing management problems in food and drug supervision, and severely crack down on illegal food and drug activities.
It is forbidden to try bio-pesticides with highly toxic pesticides. Food safety issues should be tackled at the source. How to ensure food safety for agricultural products is the key to tracing the source and supervising pesticide residues.
How to supervise the problem of pesticide residues, Xu Jin put forward two suggestions: First, the prohibition of the production and use of highly toxic pesticides, respected biological pesticides; Second, as soon as possible to develop pesticide residues detection equipment, strict management of pesticide residues.
“The problem of pesticide residues is daunting. From the perspective of market supervision, the detection system is still not perfect.†Xu Jin said that in the actual use process, everyone did not pay attention to this issue, but this issue is related to the people’s livelihood and even safe, should rise At the national level.
“Can we combine the use of biological pesticides with the national preferential agricultural policies and encourage farmers to use ecological pesticides by granting relevant subsidies, and strictly control the use of highly toxic pesticides by farmers.†Xu Jin said that although the state has banned the production of highly toxic pesticides, Some countries may, for the sake of profit, still produce as usual. For this phenomenon, the state should further improve the relevant supervision system. Once this phenomenon is found, it must not only impose punishment but also investigate criminal responsibility.
Talking about biological pesticides, Xu Jin has his own experience. According to reports, 15 years ago, he focused on the problem of pesticide residues. He also deliberately sought 50 mu of land for the experiment. The results showed that using biological pesticides can also make crops grow well. “Compared with some highly toxic pesticides, the cost of biological pesticides may be higher. It is recommended that the country combine the promotion of the use of biological pesticides with the benefits of agricultural policies and provide farmers with certain compensation according to relevant standards.â€
Sodium Tripolyphosphate, Na5P3O10, Molecular weight 367.86, white powder; Melting point 622 °C. free soluble in water, aqueous solution appears ACID. It has got salient chelating capacity to metal ions of Ca and Mg etc. and can soften hard water to make suspension into solution, alkalinity, without causticity. It is an inorganic compound with formula Na5P3O10, is the sodium salt of the polyphosphate penta-anion, which is the conjugate base of triphosphoric acid.Sodium tripolyphosphate is produced by heating stoichiometric mixture of disodium phosphate, Na2HPO4, and monosodium phosphate, NaH2PO4, under carefully controlled conditions.
It has different bulk density, i.e. low density 0.35-0.6g/cm 3 , medium density 0.6-0.8g/cm3 and high density 0.8-1.0g/cm3. This product has two crystalline forms, namely phase I (high temperature phase) and phase II (low temperature phase). The chemical properties of the two phases are the same, and the difference between them lies in the thermostability, hygroscopicity, solubility and hydration heat when dissolving.
It can be used as one of the main auxiliaries for synthetic Detergent, synergist for soap; water softener, tanning agent for leather making, auxiliary for dyeing; As an effective dispersion agent for suspensions of coatings, kaolin, magnesium oxide, calcium carbonate and drilling mud etc.
As an oil contamination resistance agent in paper production; As in foodstuff industry it is used as quality improver in the process of canned food, fruit juice drinks, foodstuffs from milk or soybeans. It may tender the meat in canned ham and soften the skin of horse bean in canned horse bean. It may also serves as a softener or densifier in foodstuff industry.
