Problems solved by technology

Initially, aluminum hydroxide was prepared from aluminum sulfate, sodium hydroxide and sodium carbonate, but its biggest disadvantages: 1) The generated by-product sodium sulfate, its sulfate radical (SO 4 2- ) not only affects the adsorption of the matrix to the pigment, but also strips the adsorbed pigment from the matrix; 2) the solubility of sodium sulfate is not large, and it needs to be eluted (SO 4 2- ) is b

example 1

[0048] Example 1, the preparation of edible bright blue lake:

[0049] In a 500ml four-necked glass flask equipped with a stirrer, a thermometer and a dropping funnel, add 0.1mol sodium bicarbonate, 0.0024mol edible brilliant blue, and 250ml water in sequence, stir and dissolve, then slowly add dropwise below 40°C 0.039mol aluminum trichloride aqueous solution, control the pH value in the range of 3.5 to 6.8, drop the aluminum trichloride aqueous solution within a few hours, continue to stir until the material is separated, and filter. After the filter cake is beaten with water three or four times and filtered (the number of times of beating and filtration depends on the measured value of chloride ≤ 2.0%), about 50 milliliters of water is added to the filter cake of the final gained product to obtain about 5.1 grams of finished product after beating and spray drying.

example 2

[0050] Example 2, the preparation of edible lemon yellow lake:

[0051] The operation is the same as in Example 1, except that 0.0035 mol of edible tartrazine and 0.038 mol of aluminum trichloride are substituted.

example 3

[0052] Example 3, the preparation of edible sunset yellow lake:

[0053] The operation is the same as in Example 1, except that 0.0021 mol of edible sunset yellow and 0.040 mol of aluminum trichloride are substituted.

Abstract

The present invention belongs to the field of food additive technology, and discloses an improved edible colour lake preparation method. On the basis of adopting aluminium trichloride and sodium hydrogen carbonate as matrix said invention can regulate and select the temp. of colour lake, pH value and proportioning condition so as to make the edible colour lake product colour bright, appearance difference small, grain size small, water-proof dissolving out property good, content range by increased and chromatographic specification complete.

Description

Technical field: [0001] The invention belongs to the technical field of food additives. Specifically relates to a preparation method of special food additive edible color lake. Background technique: [0002] Special food additive edible color lake has excellent properties such as strong tinting power, bright color, high safety, and harmless to health. It is widely used in new packaging materials with high added value, medicine, and high-grade food, such as: medicine and biological Capsules of health products, children's food and toys, high-end cosmetic care products, also suitable for edible packaging materials ink, baked food, candy coating, dairy products, solid beverages, condiments, pet food, etc. [0003] The pigment dissolution of edible color lake in the electrolyte solution is the result of ion exchange between the anion in the electrolyte solution and the pigment anion in the color lake. The order of strength of the electrolyte ion that can make the anion dissolve ...
