Embodiment 1

[0033] a) Take 1000 g of ripe fruits with shells of Gardenia jasminoides, pulverize them with a traditional Chinese medicine pulverizer, pass through a 40-mesh sieve, add 8 times the amount of 50% ethanol, extract at 30-70° C. for 2 hours, and filter with gauze to obtain a crude extract of gardenia yellow pigment;

[0034] b) The crude extract containing gardenia yellow pigment in step a) is micro-filtered with a 200nm ceramic membrane at 30°C and a pressure of 0.2MPa until clarified; then with a 3000Da ultrafiltration membrane at room temperature and a pressure of 0.4MPa Refined by ultrafiltration; then use a nanofiltration membrane with a molecular weight cut-off of 150Da to concentrate by nanofiltration at room temperature and an operating pressure of 3.0MPa; freeze-dry the concentrated solution to obtain a freeze-dried powder of gardenia yellow pigment; During the process, when the remaining feed liquid is 30% of the weight of the raw material liquid, water of 1 times the a...

[0039] a) Take 1000 g of ripe fruits with shells of Gardenia jasminoides, pulverize them with a traditional Chinese medicine grinder, pass through a 40-mesh sieve, add 5 times the amount of 45% ethanol, extract at 30-70° C. for 2 hours, and filter with gauze to obtain a crude extract of gardenia yellow pigment;

[0040] b) The crude extract containing gardenia yellow pigment in step a) is micro-filtered with a 200nm ceramic membrane at 30°C and a pressure of 0.2MPa until clarified; then with a 3000Da ultrafiltration membrane at room temperature and a pressure of 0.4MPa Refined by ultrafiltration; then use a nanofiltration membrane with a molecular weight cut-off of 150Da to concentrate by nanofiltration at room temperature and an operating pressure of 3.0MPa; freeze-dry the concentrated solution to obtain a freeze-dried powder of gardenia yellow pigment; During the process, when the remaining feed liquid is 30% of the weight of the raw material liquid, water of 1 times the amou...

Embodiment 3

[0045] a) Take 1000 g of ripe fruits with shells of Gardenia jasminoides, pulverize them with a traditional Chinese medicine grinder, pass through a 40-mesh sieve, add 8 times the amount of 50% ethanol, extract at 30-70° C. for 2 hours, and filter with gauze to obtain a crude extract of gardenia yellow pigment;

[0046] b) The crude extract containing gardenia yellow pigment in step a) is microfiltered with a 150nm ceramic membrane at 40°C and a pressure of 0.2MPa until it becomes clear; Refined by ultrafiltration; then use a nanofiltration membrane with a molecular weight cut-off of 100Da to concentrate by nanofiltration at room temperature and an operating pressure of 3.0MPa; freeze-dry the concentrated solution to obtain a freeze-dried powder of gardenia yellow pigment; During the process, when the remaining feed liquid is 30% of the weight of the raw material liquid, water of 1 times the amount of the remaining feed liquid can be added to continue microfiltration, and repea...

Abstract

The invention discloses a Gardenia yellow yeast microcapsule and a preparation method thereof. Mature Gardenia fruits are extracted, purified and lyophilized to obtain lyophilized powder that serves as a core material, yeast cells are used as an embedding wall material, the two materials are lyophilized to obtain the Gardenia yellow yeast microcapsule; via microencapsulation of the yeast cells, the activity of Gardenia yellow is retained, and the nutrition of the yeast cells is imparted; the microcapsule that is of dried powder is easy to apply and good in storage performance; no toxic or harmful substances are added in the making process, the Gardenia yellow yeast microcapsule that is made is safe, nontoxic and richly nutrient and can be added to food safely; a new direction is also provided for the application and development of natural pigments.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a yeast microcapsule of gardenia yellow pigment and a preparation method thereof. Background technique [0002] Pigments are often used to improve product appearance, attract consumers' attention, and increase consumers' desire to buy. Since the first artificial pigment was synthesized in 1986, synthetic pigments have rapidly replaced natural pigments and dominated the market due to their advantages such as diverse hues, strong tinting strength, and suitability for mass production. With the development of society and the improvement of people's living standards, people pay more and more attention to food safety issues, and the problems of synthetic pigments endangering human health have been seriously highlighted. Natural pigments are becoming more and more popular. However, there are only 44 kinds of natural pigments allowed to be used in my country, and natural yell...
