The invention discloses haematochrome preparation which is bright red in the condition of PH4 acidity, stable in optothermal condition and can be used as food additives. The high-stability natural compounded haematochrome preparation is formed by mixing cochineal haematochrome or lag haematochrome with 0.01-10% by weight of ammonium carbonate or ammonium bicarbonate. The high-stability natural compounded haematochrome preparation is shown in bright red when being used in various acidic food and beverage, can be kept red stably in the optothermal condition and is permitted to be used as food additives.
Description
technical field [0001] The invention relates to the field of acid-resistant red pigment preparations, more specifically, a highly stable natural compound red pigment preparation suitable for various acidic foods and drinks. Background technique [0002] In the past, synthetic pigments were mostly used as food pigments. Due to many safety problems in synthetic pigments, they were gradually replaced by natural pigments. Now, natural pigments are widely used in food, beverages, health care products, medicines and cosmetics, especially in the coloring of food. However, due to the instability of natural pigments, there are problems in use. For example: natural pigments will change in hue and fade due to the influence of light, oxygen, temperature, etc., which will reduce the value of commodities. [0003] Carmine and lac red pigments are stable to light and heat, and have strong stability in acidic environments. The hue of the above pigments in solution: orange in acidic solut...
