Problems solved by technology

However, taking the production of salt-baked chicken as an example, the application of gardenia yellow pigment in salt-baked chicken shows the characteristics of light intolerance
In order to improve the shelf life of products, color-protecting agents are usually used in this field to enhance the color of products. Currently, the color-protecting agents developed for gardenia yellow pigments use chlorogenic acid compositions (CN102835649A), but the chlorogenic acid color-protecting technology There are certain limitations, especially when the method is applied to salt-baked chicken, the color protection effect of gardenia yellow pigment is poor, and the effect of light resistance and high temperature resistance of gardenia yellow pigment is poor, which affects the appearance of salt-baked chicken products. make an impact

Embodiment 1-12

[0042] Examples 1-12 are used to illustrate the preparation method of the color-protecting agent provided by the present invention.

[0043] Weigh respectively according to the conditions listed in Table 1: compound phosphoric acid (sodium pyrophosphate, sodium tripolyphosphate, sodium hexametaphosphate), phytic acid substances (phytic acid and / or sodium phytate); Mix, grind, and pass through a 60-mesh sieve to obtain color-protecting agent 1-12.

[0044] Among them, the carrier (dextrin (150g), sucrose (120g), glucose (30g)) was also added in Preparation Example 10;

[0045] Among them, the carrier (dextrin (100g), L-ascorbic acid (100g)) was also added in Example 11;

[0046] However, in Example 12, a carrier (glucose (50 g), D-isoVc sodium (50 g)) was also added.

[0047] Table 1

[0048]

preparation example 1

[0060] Preparation Example 1 is used to illustrate the food coloring method provided by the present invention.

[0061] Chicken soup (precooked 500g chicken with 5kg water) 2.5kg, add 0.3g gardenia yellow pigment, heat until the chicken soup boils; take 500g marinated and precooked 8-mature chicken, add boiling pigmented In the chicken soup, keep it at a slight boil for 20 minutes; take the color-protecting agent 1 (0.5 g) prepared in Example 1, put it into the chicken broth that has been colored for 20 minutes, stir well, and keep it at a slight boil for 5 minutes. Remove the chicken. The chicken was naturally dried to obtain product 1 by avoiding light and ventilating.

preparation example 2

[0063] Preparation Example 2 is used to illustrate the food dyeing method provided by the present invention.

[0064] Chicken broth (soup obtained by pre-boiling 500g of chicken with 5kg of water) 2.5kg, add 0.3g of gardenia yellow pigment, take the color-protecting agent 1 (0.5g) prepared in Example 1, and heat until the chicken broth boils; take marinated and Put 500g of pre-cooked 8-mature chicken into boiling chicken broth, keep it in a slightly boiling state for 20 minutes, and then remove the chicken. The chicken is naturally dried to obtain product 2 by avoiding light and ventilating.

Abstract

The invention discloses a gardenia yellow pigment color fixative. The color fixative is prepared by uniformly mixing a raw material mixture. The raw material mixture comprises a composite phosphate and a phytic acid type compound. The composite phosphate comprises sodium pyrophosphate, sodium tripolyphosphate and sodium hexametaphosphate. The phytic acid type compound is at least one of phytic acid and sodium phytate. The invention also discloses a food dyeing method. The method includes using a gardenia yellow pigment and the color fixative provided by the invention. When the color fixative is applied for dyeing food by the gardenia yellow pigment, the light resistance and high-temperature resistance of the gardenia yellow pigment can be significantly enhanced. In particular, dyeing effects of bright color, stability, high-temperature resistance and light resistance can be obtained when the gardenia yellow pigment color fixative is applied for dyeing salt-roasted chicken.

Description

technical field [0001] The invention relates to a gardenia yellow pigment color-protecting agent and a food dyeing method Background technique [0002] Gardenia yellow is a natural water-soluble carotenoid, which is extracted and refined from the fruit of Rubiaceae gardenia, and can be diluted with dextrin in powder, extract or liquid food additive. Including crocetin, crocetin, geniposide. It is clearly stipulated in the standard GB2760-2011 that gardenia yellow pigment can be used in cooked meat products (only poultry meat cooked products) in an amount of 1.5g / kg. However, taking the production of salt-baked chicken as an example, the application of gardenia yellow pigment in salt-baked chicken shows the characteristics of light intolerance. In order to improve the shelf life of products, color-protecting agents are usually used in this field to enhance the color of products. Currently, the color-protecting agents developed for gardenia yellow pigments use chlorogenic ac...
