Uniform powder or particles in reddish brown or dark reddish brown, odorless, strong light resistance and heat resistance (105℃), stable to citric acid and tartaric acid, and dark red in alkaline solution. Soluble in water, red with blue, soluble in glycerol, slightly soluble in ethanol, insoluble in oil. This product is easy to fade in contact with copper and iron, easily decomposed by bacteria, and has poor oxidation resistance and reducibility, so it is not suitable for fermented food. It can be used for high-sugar juice (flavor) or juice (flavor) drinks, carbonated drinks, mixed wine, candy, cakes, green plums, hawthorn products and pickled side dishes, with the maximum dosage of 0.05 g/kg. Used for red and green silk and green cherry (for decoration).
Curcumin [physical properties] orange crystalline powder, melting point 183. Insoluble in water and ether, soluble in ethanol and glacial acetic acid. [Chemical Properties] Curcumin is a yellow pigment extracted from the rhizome of Curcuma longa, and its main component is curcumin, accounting for about 3% ~ 6% of Curcuma longa. It is a rare pigment containing diketones in the plant kingdom, and it is a diketone compound. Curcumin is orange-yellow crystalline powder with a slightly bitter taste. Insoluble in water, soluble in ethanol and propylene glycol, soluble in glacial acetic acid and alkali solution, reddish brown in alkaline state and yellow in neutral and acidic state. Strong stability to reducing agent, strong color rendering (no color rendering to protein), not easy to fade after color rendering, but sensitive to light, heat and iron ions, poor light, heat and iron ion resistance.
Curcumin is mainly used for coloring sausage products, canned food, sauces and halogen products, and its usage depends on the needs of normal production.
In addition, radish red, sorghum red, safflower yellow and other edible natural pigments are often used as colorants in the production of cooked meat products, canned food and other foods.
Sodium copper chlorophyllin is easily soluble in water and ethanol solution, and the aqueous solution is transparent and green, which deepens with the increase of concentration, and has good light resistance, heat resistance and stability.
[Ingredients] The main components are sodium copper chlorophyllin (disodium) and sodium copper chlorophyllin (trisodium).
【 Usage 】 It can be widely used in food pigments, beverages, cosmetics and medicines.
[Usage] It can be used after diluted with purified water to the required concentration.
Natural green pigment-sodium copper chlorophyllin is a natural pigment made from sodium copper chlorophyllin through fine processing. Chlorophyll exists widely in all green plants. At present, chlorophyll is extracted from plants (such as spinach) or dried silkworm excrement, and then processed and purified by scientific methods to obtain natural chlorophyll derivative-sodium copper chlorophyllin. Sodium copper chlorophyllin has been approved for use in food by relevant international health organizations, and it is also an edible natural pigment approved by China.
Main ingredients: sodium copper chlorophyllin.
Properties: dark green water-soluble liquid or dark green powder.
Features: It has the hue of natural green plants, strong coloring power and slightly poor light and heat stability, but it has good stability in solid food and precipitation occurs in solution with PH < 6. This product is more suitable for neutral or alkaline (pH 7 ~ 12) food.
Application: canned green peas, fruit and vegetable juices, pulp drinks, juice (seasoning) drinks, carbonated drinks, mixed wine, ice cream, popsicles, jellies, cakes, biscuits and sweets.
