What is the "disodium edetate"?
A few days before the food business network news , in the results of the sampling inspection by the Food and Drug Administration, it was said that a company’s vanilla was found to contain “disodium edetate†and pointed out that this ingredient is not allowed to be used by national standards. of. You may ask, what is this "disodium edetate"? Is the ordinary snack to add to this seemingly "very chemistry" thing? Who is "disodium edetate" Ethylene-diamine-tetra-acetate, also known as EDTA-disodium. Sounds very chemistry? Indeed, it is a good compounding agent in chemistry. In addition to the chemical field, it is also used in the food industry. Ethylenediaminetetraacetic acid disodium and ethylenediaminetetraacetic acid dicalcium are legal food additives specified in GB 2760-2014 "Food Safety National Standards for the Use of Food Additives", which mainly play a role in stabilizers and solidification in food processing. The function of the agent, antioxidant and preservative (the function of diammonium ethylenediaminetetraacetate is antioxidant). At the same time, the official documents also clearly stipulate that the two have different scope of use and usage. Dicalcium edetate can only be used in compound seasonings, the amount can not exceed 75mg/kg, and disodium edetate can be used in foods such as jam, candied fruit, pickled vegetables, canned vegetables, etc. The amount also varies depending on the type of food. What is the use of "disodium edetate"? With the protection of EDTA-disodium, it can help some processed foods to resist the deterioration caused by oxidation, inhibit the proliferation of microorganisms, delay the corruption of food, and thus "maintain the image." Without it, it would be difficult for us to enjoy a wide variety of foods with ease and convenience. However, the industry has a specialization, EDTA-disodium is limited to the use of sweet potato fruit. As long as such food additives are legally used within the scope of use and in accordance with the prescribed amount of use, the produced food will not cause harm to human health. The reason why the General Administration has to investigate the company that produces vanilla is that it is not because the vanilla is not a sweet potato, so it should not be used. Is it harmful after adding it? It is worth noting that although the regulations do not allow the use of EDTA-disodium in vanilla, it does not mean that it is harmful in the use of vanilla. The reason may be that the application has not been declared, so the relevant departments have not evaluated their security risks, or the relevant departments believe that it is not necessary to use EDTA-disodium in the vanilla. However, if you really eat unqualified vanilla, is it harmful to your body? As early as 1974, the FAO/WHO Joint Expert Committee on Food Additives (JECFA) approved the use of EDTA-disodium, EDTA-sodium calcium as a food additive in the food industry, and determined that sodium edetate calcium salt is allowed daily. Intake (ADI) is 0-2.5 mg/kg body weight, which means that 150 mg is safe as long as the daily EDTA-disodium intake is not exceeded (calculated by adults weighing 60 kg). In other words, if you eat no more than 429 grams of EDTA-disodium 350 mg / kg of vanilla, you will not be harmful to your health. Of course, we should pay attention to "appropriate amount" when eating any food. In terms of dietary mix, snacks such as can be used as part of a healthy diet. However, due to the problems of sugar, high energy and high sodium content, such foods are only suitable for occasional taste adjustment, avoid greed, and should pay attention to the formality of the channel when purchasing. What are the relevant regulations in the world? So, what foods in the world are prescribed to add EDTA-disodium? EU: Currently only CaNa2EDTA is allowed, mainly for frozen or quick-frozen, bottled or filled crustacean foods and sauces, and no Na2EDTA regulations are available. US: The function, scope and dosage of EDTA-disodium as a food additive are clearly defined. For example, it can be used as a preservative in salad dressing and mayonnaise. The amount should not exceed 75 mg/kg, and it can also be used in canned beans. The function of the color-protecting agent in the frozen potato products is not more than 165 mg/kg and 100 mg/kg, respectively. However, there is no provision for the use of EDTA-disodium for candied foods. International: CODEX's food additive category name and International Coding System, General Standard for Food Additives (GSFA), there are two EDTA compounds that are allowed to be added - CaNa2EDTA (INS No. 385) and Na2EDTA (INS No) .386). China: According to China GB 2760-2014 "Food Safety National Standards for Food Additives", jam, sweet potato, pickled vegetables, canned vegetables, vegetable puree / sauce (except tomato sauce), canned nuts and seeds, canned grains In the nine types of foods, such as compound seasonings and beverages (excluding packaged drinking water), EDTA-disodium can be added in an appropriate amount. The "appropriate amount" of different types of foods is: the maximum use of beverages is 30 mg / kg. The maximum use of jam and vegetable puree is 70 mg/kg, and the maximum use of compound seasoning is 75 mg/kg. The sweet potato, pickled vegetables, canned vegetables, canned nuts and seeds, canned food can not exceed 250 mg. /kg. Dicalcium edetate can only be used in compound seasonings with a maximum usage of 75 mg/kg. Therefore, when you go to the supermarket to buy food, if you find that there is ETDA-disodium in these foods, you don't have to worry about it. The ETDA-disodium in these foods is certified and is justified.
