Conclusion: in conformity with the enterprise standard |
Curcumin has long been widely used in the food industry as a commonly used natural pigment, mainly used for dyeing canned food, sausage products, and marinated products. Its usage is determined by normal production needs. Functional foods with curcumin as the main ingredient can be in the form of general food or some non-food forms, such as capsules, pills or tablets. For general food forms, some yellow pigment foods can be considered, such as cakes, sweets, beverages, etc. Curcumin is a food additive approved by the Food and Agriculture Organization of the United Nations Codex Alimentarius Commission (FAO/WHO-1995). It is one of the nine natural pigments allowed to be used in food and was first promulgated in my country's "Hygiene Standards for the Use of Food Additives". The newly promulgated "Standard for the Use of Food Additives" (GB 2760-2011) stipulates that the maximum use amount of curcumin in frozen drinks, cocoa products, chocolate and chocolate products and candies, gum-based candies, decorative candies, toppings and sweet sauces, batters, breading and frying powders, instant rice and flour products, seasoning syrups, compound seasonings, carbonated beverages and jellies is 0.15, 0.01, 0.7, 0.5, 0.3, 0.5, 0.5, 0.1, 0.01, 0.01 g/kg respectively. Margarine and its similar products, cooked nuts and seeds, grain product fillings and puffed foods can be used in appropriate amounts according to production needs.
Curcumin also has a preservative effect. At present, curcumin is widely used in the food industry as a condiment and pigment at home and abroad. Turmeric can replace the precious spice saffron in medieval Europe. It is also an indispensable traditional curry food in Indian life, a common condiment for grilled meat rolls in the Middle East, Persian and Thai dishes, and a common pigment in mustard sauce. Curcumin used for food coloring is mainly divided into four categories: water-dispersible turmeric oil, water-dispersible purified turmeric, oil-soluble purified curcumin and purified turmeric powder.
my country began to study and apply curcumin in the mid-to-late 1980s, and reached its peak in the early 1990s, but due to product quality reasons, the degree of marketization was not high. At present, China has developed water-soluble and oil-soluble curcumin products comparable to those abroad. Through compounding, curcumin of various tones has been produced, which has been widely used in pasta, beverages, fruit wine, candy, cakes, canned food, juice and cooking dishes. As a compound seasoning, it is used in chicken essence compound seasoning, puffed seasoning, instant noodles and puffed noodle products, instant food seasoning, hot pot seasoning sauce, paste flavors and spices, seasoning pickles, beef jerky products, etc. my country is one of the main producers of turmeric in the world, with rich resources. The current annual output has reached tens of thousands of tons, and it has a good market advantage.
