Problems solved by technology

Carminic acid is considered to be one of the safest natural pigments. It is easily soluble in water, dilute acid, dilute alkali, ethanol, and propylene glycol. It is not easy to spread in the product to form color spots, which greatly limits its application range

Embodiment 1

[0033] Take 20 grams of soybean oil as the oil phase, 804 grams of Span as the lipophilic emulsifier, and 10 grams of pure carminic acid aqueous solution with a concentration of 68% as the inner water phase, and mix the inner water phase, the lipophilic emulsifier and the oil phase , stirred for 6 minutes at a speed of 10,000 rpm on a high-shear dispersing emulsifier to obtain colostrum. Get 20 grams of colostrum, mix it with 20 grams of aqueous solution containing 30% by weight of sucrose fatty acid ester, and stir it for 6 minutes at a speed of 2000 rpm on a high-shear dispersing emulsifier, measure the centrifugal stability of the compound emulsified coloring agent sex.

Embodiment 2

[0035] Colostrum was prepared in the same ratio as in Example 1, except that the stirring speed on the high-shear dispersing emulsifier after the components were mixed was 3000 rpm. Then, a compound emulsified colorant was prepared at the same ratio and at the same rotational speed as in Example 1, and the centrifugal stability of the compound emulsified colorant was measured.

Embodiment 3

[0037] Colostrum was prepared in the same proportion as in Example 1, and then the colostrum and the external water phase were mixed in the same proportion as in Example 1, except that the stirring speed of the colostrum and the external water phase in the high-shear dispersing emulsifier was 8000 rpm. Determination of the centrifuge stability of the compound emulsified colorant.

[0038] The experimental results of Examples 1-3 are shown in Table 1 below.

[0039] Table 1

[0040] Example Example 1 Example 2 Example 3 centrifugal stability 95％ 88％ 92％

[0041] In the results described in the above table, the centrifugal stability of embodiment 1 is the best, followed by embodiment 3, and embodiment 2 is the worst. It shows that the shear speed has a certain influence on the stability of the compound emulsified colorant. In the preparation of colostrum, a high shear speed is required to obtain a uniform and stable emulsion, while in the compounding...

Abstract

The invention relates to a preparation method and application of a cochineal-embedded W / O / W type compound emulsifying colorant. The preparation method is characterized by comprising the steps of mixing 1 part of a pure cochineal acid water solution, 2 parts of an oil phase and 0.1-1 part of a lipophilic emulsifying agent in parts by mass, stirring at a rotation speed of 3000r / min-15000r / min for 3-9 minutes so as to obtain a W / O type primary emulsion, mixing 1-3 parts of the W / O type primary emulsion with 2-3 parts of an outer water phase, and stirring at a rotation speed of 1000r / min-8000r / min for 3-9 minutes so as to obtain W / O type compound emulsion. By embedding pure cochineal acid by virtue of the preparation method, the stability of the cochineal acid under an acidic condition can be improved, and the problems that cochineal acid forms color spots in foods and is unlikely to be smeared are solved; and meanwhile, by utilizing cochineal acid which does not contain aluminum as a colorant, the food safety problem caused by aluminum-containing color lakes is avoided, and the use range of the cochineal in the food field can be further expanded.

Description

technical field [0001] The invention relates to the food industry, in particular to a method for embedding cochineal carmine W / O / W compound colorant and its application as colorant in surimi products and beverages. Background technique [0002] The color of food can increase appetite, increase the secretion of digestive juice, and promote the digestion and absorption of food in the human body. Therefore, in order to obtain good food color, people often add food coloring during food processing. According to its source, it can be divided into synthetic There are two types of pigments and natural pigments. Synthetic pigments have a series of advantages such as bright color, strong tinting strength, and good stability, but most of them are toxic (including toxicity, diarrhea, and carcinogenicity), and can cause varying degrees of damage to the human body. Edible pigments derived from natural animals and plants are called natural food pigments, which have high safety, natural co...
