对食品添加剂的认识-利弊（Understanding of food additives - pros and cons） 对食品添加剂的认识-利弊(Understanding of food additives - pros and cons) Understanding of food additives [Abstract] in recent years, China has continuously food safety problems on food additives, awareness of food additives has been distorted, as long as food additives are harmful to health. Here I will start a rational knowledge of food additives, objective understanding of the advantages and disadvantages of food additives, so as to guide us to the proper use of food additives in life, to prevent food safety problems. [Key words] food additives, the pros and cons of prevention Food additive is used to improve food quality and prolong the shelf life of food for food processing and adding a kind of chemical synthesis or natural substances in food nutrition. Food additives is to improve food color, flavor and taste quality, and the need for the preservation and processing and adding food compounds or natural substances. At present, China's food additives in the classification of goods a total of 35 categories, including flavor agent, defoaming agent, leavening agents, colorants, preservatives and other additives, including more than 10000 kinds of food. Among them, "the use of food additives in food additive standards" and the Ministry of health notice allowed is divided into 23 categories, a total of 2400 kinds of developed country or industry quality standard of 364. The main acidity regulator, anti caking agent, defoaming agent, antioxidant, bleaching agent, leavening agent, gum based candy based agent, colorant, color protecting agent, emulsifier, enzyme preparation, flavoring agent, flour treatment agent, coating agent, water retention agent, nutritional supplements, anti-corrosion agent, stabilizer and coagulant, sweetening agent, thickening agent, food flavor, food industry and other 23 kinds of processing aids. Now commonly used food pigments include two categories: natural pigment and synthetic pigment. Natural pigment from natural products, mainly by plant tissues, including some pigment from animal and microorganism. Synthetic pigment is an organic pigment prepared by artificial chemical synthesis method, is mainly to separate aniline dyes in coal tar as raw material. In a very long period of time, because people are not aware of the harm of synthetic pigment, and pigment and natural pigment compared with bright color, strong coloring, stable quality and low price, many countries in the food processing industry commonly used synthetic pigment. With the development of society and the improvement of people's living standard, more and more people for the use of synthetic pigment in food will not cause harm to human health question. At the same time, a lot of research report pointed out that almost all synthetic pigment can provide nutrients to the human body, some synthetic pigments will even endanger human health. Recently, more and more media reported many negative reports on food additives, such as Shuanghui "Clenbuterol", Taiwan food "plasticizer" and so on, can make us uncomfortable, we ask ourselves what we eat what has no food additives, and how much food is safe. This series distorts our understanding of food additives, many people are talking about the color variety of food additives. The image of food additives in the people's heart suddenly became a source of all evils in food safety. But such is not the fact, Food additive is not synonymous with illegal additives, we should remain rational in a variety of reports, a correct understanding of the advantages and disadvantages of food additives, good food safety work at the same time, improve our food beauty. A food additive, and Food additive has greatly promoted the development of food industry, and it is regarded as the soul of modern food industry, which is mainly for the food industry have brought many advantages, its main function is as follows: first, to save, to prevent spoilage. For example: the preservative can prevent food spoilage caused by microorganisms, prolong the retention period of food, but also can prevent microbial contamination caused by food poisoning effect. Another example: antioxidants can prevent or delay the oxidation of food, in order to provide food stability and storability, also can prevent the formation of potentially harmful substances on the oxidation of lipids. In addition, can also be used to prevent food, especially fruits and vegetables of the enzymatic and non enzymatic browning. These for food preservation are significant. Two, improve the sensory properties of food. The food color, flavor and taste, shape and texture is an important index to measure the quality of food. The appropriate use of color agent, coloring agent, bleaching agent, flavouring and emulsifier, thickener and other food additives, can significantly improve the sensory quality of food, meet people's different needs. Three, to maintain or improve the nutritional value of food Appropriate to add some nutrients belonging to the natural range of food nutrition fortifier in food processing, can greatly improve the nutritional value of food, which has important significance to prevent malnutrition and lack of nutrition, promote balanced nutrition and improve people's health level. Four, increase the variety and convenience food. Now the market has up to more than 20000 kinds of food available to consumers, although the production of these foods are mostly processed by certain packaging and different processing methods, but in the production process, some color, aroma and taste of the products, most of the varying degrees of added a color, aroma, flavor and other food additive. It is these many foods, especially convenience food supply, bring great convenience to people's life and work. Five. Good food processing, to meet the production mechanization and automation. The use of defoaming agent, filter aid agent, stabilizer and coagulator etc. in food processing, food processing operations can be beneficial. For example, when using the gluconic acid delta lactone as coagulant of tofu, tofu can be beneficial to the mechanization and automation of production. Six, to meet the special needs of others. The food should be possible to meet the different needs of people. For example, patients with diabetes can not eat sugar, usable non nutritive sweeteners or low calorie sweeteners, such as three sucrose or aspartame made of sugar free food supply. Thus, in fact, food additives and people's daily life is closely related, most of the additives have good effect on the balance of nutrition, improve the quality of the food. Two, food additives. Food additives should be used to improve food quality and prolong the shelf life of food for food processing and chemical synthesis of natural substances or increase the nutrient composition of food, But there are unscrupulous traders in order to reduce the cost, cover up the quality defects and other additives in food mixed with harmful to human health. From the numerous reports, it is easy for us to see the food additives has become a great threat to our food safety. The use of food additives will not do harm to our health. It may cause chronic physical illness, weight is caused by food poisoning and even death. Food additives are not completely harmless, to grasp the principle of caution, use less, to avoid the abuse of food additives health hazards. There are 4 main categories of food enterprises use of food additives, one is to use is not correct, some companies use additives not to improve food quality, improve the nutritional value of the food itself, but in order to meet the consumer demand, reduce the cost of the senses, the principle of violation of food additives; the two is to use the scientific method, does not conform to the food additives health standards, super scope, excessive use; three is to achieve the desired effect under the condition of not reduce as much as possible in the food consumption; the four is not clearly marked on food labels, misleading consumers. In January 2001, Zhejiang Hangzhou area because food containing "Clenbuterol" pork, more than 60 food poisoning; in March 2003, some students and teachers in Liaoning Haicheng area drinking soy milk food poisoning, poisoning 292 people, 1 people were killed. The survey is active in trypsin inhibitor anti nutritional molecules not completely destroyed; in April 2004, Anhui Fuyang fake milk powder incident, resulting in 171 infant malnutrition, 13 infants who died. The survey is serious milk does not comply with national health standards; May 2004, occurrence of alcohol poisoning in Baiyun District of Guangzhou City, 46 hospitalizations and 9 deaths. The survey is the formaldehyde content of high edible alcohol industry standard alcohol; 2005 tonyred, malachite green, bright milk, and then return to factory processing sales Nestle milk iodine exceed the standard. Major food safety incident, exposed food safety in our country there are still imperfect legal system, supervision and management system is not smooth, safe and standard backward detection technology behind a series of problems. Three, right guard The functions of the government departments how to safeguard the legitimate rights and interests of consumers: one is to establish and improve the food safety management system and standard system of law. The current "Food Sanitation Law" to conduct a comprehensive revision, construction of food safety legal system is relatively independent. Since the implementation of the "Food Sanitation Law" summed up the experience and lessons, study, learn from the advanced experience of foreign food safety management, in the economic globalization today, China's food safety management law system and international standards as soon as possible; the two is to establish a unified management system of food safety supervision. Established by the Ministry of health food hygiene supervision and management of the national quality inspection work; responsible for administration in conjunction with relevant departments to develop and approve the issue of food standards, responsible for measurement standards of food production enterprises to implement and other product quality supervision work outside the special legal provisions; SAIC is responsible for the business license of food production and business units responsible for the management of food circulation order supervision; Ministry of agriculture is responsible for agricultural products supervision; other departments in charge of the industry within the scope of their respective duties of management; The three is to increase the intensity of unscrupulous traders. In June 1, 2009 the formal implementation of the "food safety law", this is for the state government departments of law, the imperial sword, strict law enforcement, believe this will be the implementation of illegal food production enterprises a strong deterrent. As consumers how to safeguard their own interests? First of all, to ask why several. When choosing foods, we should be with the question: why is this so bright color ham this ice cream? Why so cheap? Why is this so delicious rice flour? Why is this so white? Why this Vegetable Salad has not withered with? This simple spirit of doubt, if we buy food color, flavor, form beyond our common sense, you can add a suspected illegal additives or the existence of the abuse of food additives; secondly, not greedy small convenience. According to expert opinion, the majority of the regular manufacturers selling food, not prone to the phenomenon of abuse and misuse of food additives. Consumers do not buy some food in order to facilitate the production of small workshops or small greed and, because these producers are not the rational use of food additives, which itself does not have the correct use of food additives; finally, learn how to view the list of ingredients. When buying food, in addition to the production date, see the label and list of ingredients should also develop a habit, be as clear as noonday consumption. In accordance with the requirements of the pre packaged food labels in the food to add food additives must be clearly marked in accordance with the provisions of. Therefore, if you want to understand their own to buy food to add what food additives, food labels can be viewed at the time of purchase to get detailed, we want to know the contents of the label. The enterprise should have a sense of social responsibility, honesty and trustworthiness, abide by the relevant laws and regulations, respect the legitimate rights of consumers. Finally, we should intensify supervision of the media. Only through the government, enterprises, consumers, media supervision power together, we can create a safe food environment, food additive problems will not become a matter of concern for us.
