| (edible pigment) |
| Release time:2012/6/27 |
| Colorants commonly known as edible pigment, it is to point to to make food has the bright and beautiful color, improve sensory properties with stomachic and join of the material. According to its source and edible pigment properties are divided into edible natural pigment and edible pigment synthesis two kinds big. Edible natural pigment is by the plant and animal tissues extracted pigment, including microbial pigment, in addition to the natural pigment to human body have poisonous gambogic cannot use outside, the rest of the generally harmless to the human body, is more secure. Use synthetic pigment known as synthetic dyes, belongs to the synthetic pigment. Edible pigment of synthetic more in coal tar for raw material, low cost, bright color, good dyeing force, tonal diversity, but most to the health of human body has certain harm, and no nutritional value, high temperature easy to resolve. Therefore, in Fried food processing in should not be commonly use. Our national standard rules allow use of main edible pigment of red kojic rice m, caramel, turmeric, chili red element and beet red, etc. A red kojic rice, rice and monascus pigment Monascus pigment has for PH value stability, heat resistance to light chemical resistance is strong, from metal ion influence to protein and good sex and colouring stable color, safety harmless, etc. Monascus pigment commonly used sauce bittern, sausages and meat products, fermented bean curd, beverage, candy, cakes, preparation of wine coloring. Our national regulation, monascus m usage is not restricted. Second, beet red Beet red also called beets red, is to use red beet (laver head) is the root out of a natural red pigment, red and yellow beet sugar beet the anthocyanins flavin composition. Beet red for the red to red purple liquid, lump or powder or paste. Aqueous red to red purple, the PH 3.0-7.0, more stable, PH value of 4.0-5.0 stability is the largest. Dye the gender is good, but heat resistance is poor, degradation speed increases with steady rise. Light and oxygen also can promote degradation. . Our national standards, its use according to the normal production requires. Three, chili red element Chili red element main component is capsaicin, chili red element, chili jade red element. For a special odor and spicy deep red sticky liquid oily shape. Soluble in most non-volatile grease, hardly soluble in water. Acid resistance, good light is a bit poor sex. Chili red element usage according to normal production needs and decide, do not be restricted. Four, caramel Golden blonde also say the JiangSe, caramel or TangSe, is red-brown to dark brown liquid, massive, the powder material, with caramel smell and pleasant bitter taste. According to the different method, caramel can be divided into not add the ammonium salt (the ammonia method manufacturing) and add the ammonium salt (such as ammonia sulfite) production of two. Add the ammonium salt production of caramel color is better, processing convenient, the rate is higher, but there are certain toxicity. Liquid caramel is dark brown jelly, for not a single compound (about 100 different compounds). Powder or block caramel is dark brown or reddish brown. Soluble in water and propylene glycol solution. Caramel by PH value and tonal in air leakage of critical time influence, PH value above 6.0 for vulnerable to mildew. Its usage according to normal production requires. Five, turmeric pigment Turmeric extract from the root turmeric pigment a yellow pigment, the main composition is curcumin, about 3% of the turmeric-6%, the plant kingdom rare has two ketone of pigment, for second ketone compounds, turmeric pigments are orange yellow crystalline powder, taste bitter in taste. Insoluble in water, but soluble in ethanol, propylene glycol, easily soluble in glacial acetic acid and alkali solution. In alkaline as a reddish brown, in a neutral and acid as a yellow. To the stability of the reducing agent is stronger, the shading sex strong (not on the protein), is not easily fade after coloring, but light, heat, iron ion sensitive. Patience is poorer. Turmeric pigment is mainly used for such products, tin cans, smooth LuZhiPin sauce products such as color, its usage according to normal production requires. A specific reference to the state standard hygiene standards for use of food additives ". Next quarter fryers industrialized production introduced the food |
