Wang Shujun: food safety not only to quantity security but also to the quality of safety

 

CNDSN on November 2 news] (China Economic Net) as the core theme activities of the "2015 national food safety week - food safety campus," food safety science innovation public contest "on October 26, came to Tianjin," food safety public course campus tour activity also in the same period in Tianjin University of science and technology held. Tianjin University of science and technology Dr., Tianjin city "youth one thousand people plan" distinguished experts Shu Jun Wang professor in person at the scene of food safety science lectures, scientific knowledge popularization and case interpretation, Shu Jun Wang not only popularized the problem of food security "quality" and "quantity", also leading to food safety risk factor for the interpretation.
Food safety is not only the quality of the safety but also the amount of security
Food safety is a science in life. In Wang Shujun's view, the English word security Food and safety Food translated into Chinese as "food safety", but in fact, food safety in addition to include "toxic milk powder," "poison", "lean essence" and other "qualitative" security issues, but also include the "quantity" of safety issues, such as food shortages. In China, we generally talk about food safety issues are mostly point to the safety problem of the "quality".
Wang Shujun said the food quality of safety is mainly refers to the food must be non-toxic harmless, health does not cause any acute, subacute or chronic harm, in addition to the emphasis is on some accidental food safety incidents. And food "quantity" is mainly refers to a country to have sufficient safety and nutrition food, do this generally need four conditions: first, must have adequate food supply and access; two, stable and continuous supply, not because of the season or year and produce fluctuations; three, with the food can be obtained and affordable food; four, food must ensure quality safety and nutrition.
According to him, at present, the world's 7000000000 people probably have nearly 1000000000 of the population is in the food shortage of food safety issues.
At the same time, the safety of food "quality" and "quantity" is not independent of each other, but closely related. Poverty, environmental degradation and other factors can simultaneously lead to two aspects of security issues.
Food safety should pay attention to endogenous pollution
"The country people, hunger breeds discontentment, food to safety first. Food is the most basic, the lowest, the most basic requirements is safe, if even the safety can not be reached, it can not be called food, food safety and food companies are also the most basic minimum requirements." Wang Shujun said.
He said that after combing through the food safety incidents occurred in recent years can be seen, people's attention to food safety is constantly changing, from chemical pollution to pathogenic microbial contamination, and then to the processing pollution. In comparison, food safety risk factors are divided into exogenous and endogenous pollutants.
Exogenous contaminants are mostly caused by improper by use of management, through the strengthening of food safety management to eliminate and control, and endogenous contaminants is produced in the process of processing and storage, such as fried French fries or deep fried dough sticks will produce large amounts of acrylamide, barbecue middle students heterocyclic amines, these pollutants and not through the management to eliminate, so this area is the countries attach importance to the research direction.
In fact, in addition to the type of food safety issues involved, Wang Shujun believes that the nutritional imbalance is also one of the food safety problems, malnutrition, nutrition, nutrition, food safety is a problem. To obtain a balanced nutrition from an adequate diet is a basic human right in the United Nations Convention. 3
