(Original title: Han Changfu: China's agricultural product quality and safety is guaranteed)
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.
[ China Agricultural Machinery Industry News ] Everyone cares about the quality of agricultural products because it is a basic livelihood. On March 5, Minister of Agriculture Han Changfu said in an interview with the media through the “Ministerial Channel†that the quality and safety of China's agricultural products are generally stable and good, and safety is basically guaranteed.
China's agricultural product quality and safety are generally stable and good
Han Changfu said that everyone cares about the quality of agricultural products because it is a basic livelihood. Every day, we can't have three meals a day. We must eat enough first, eat well, eat well, and eat safely. This is the basic needs of people. This is the common expectation of the people. Our agricultural department has the responsibility to bring the quality and safety of agricultural products up. We are now adjusting the structure of agriculture. In fact, an important direction is to increase the supply of green, ecological and safe agricultural products. In this regard, two words: The quality and safety of agricultural products are generally stable and good, and safety is basically guaranteed. Whether it is for planting products, animal husbandry products or aquaculture products, we are inspected according to the regulations every year. The pass rate of sampling inspection is 96% and 97%. This is a basic judgment. Second, there are still some problems, so we can't relax. Our country has a large population, a large amount of agricultural products, and a large amount of food consumed every day. It may be a large percentage of 1% and 2%. Therefore, we cannot take it lightly and cannot satisfy the status quo. We must grasp the quality of agricultural products. Specifically speaking, both hands are caught and the hand is produced. It is necessary to grasp the standardization of production, rely on the main body of scale management, cooperatives, family farms, and leading enterprises to drive them. They must standardize and output. The second hand is to come out. It is necessary to strengthen supervision. This year, several measures have been taken, such as the construction of a large-scale agricultural product information platform, the market traceability of agricultural products, the retrospective supervision of the two-dimensional code of pesticides and veterinary drugs, etc., to strengthen supervision over these outstanding problems, especially to strengthen the supervision of pesticides and veterinary drugs. Do market access.
Regarding the revitalization of the dairy industry, Han Changfu said that the Chinese dairy industry has undergone a revolutionary change over the years, including the scale of farming, automation of milking, and industrial concentration. At present, the proportion of farms with more than 100 heads has exceeded 50%, achieving scientific feeding, feeding and disease control; milking mechanization prevents secondary pollution, achieving a significant increase in the quality and efficiency of raw milk; establishing a farm to the table The whole industry chain supervision system has realized standard operation and management. Han Changfu said that the dairy industry is a key point in the structural reform of the agricultural supply side. The development of China's dairy industry is shifting from quantitative expansion to quality improvement, from traditional dairy to modern dairy. Han Changfu said that before the Spring Festival this year, Xi Jinping, the general secretary of the CPC Central Committee, visited the dairy industry in Zhangjiakou City, Hebei Province. In the past, many departments of the State Council jointly issued the “13th Five-Year Plan†for the dairy industry; the next step will be focused on Raise the cattle, get good milk, strictly supervise and maintain safety, and strengthen the enterprise and tree brand. Han Changfu said, "I am full of confidence in the revitalization of China's dairy industry." I believe that one day foreign tourists will buy Chinese milk powder.
