Embodiment 1

[0024] Such as figure 1As shown, a method for extracting natural food coloring, first adopts enzyme-assisted ultrasonic leaching yellow rice yellow pigment to obtain filtrate a; After 0.33, 0.34, 0.36, 0.38, 0.4, 0.42, 0.44, 0.46, 0.48 or 0.5 times, the organic phase is obtained through two-phase water system extraction; finally, the organic phase is extracted by macroporous resin adsorption and extracted by three technologies Combined, the extraction efficiency and extraction rate of the yellow pigment of the yellow rice flower are greatly improved, the product purity is improved, the process steps are simplified, and the production cost is reduced; in order to completely and properly extract the yellow pigment from the yellow rice flower, the extraction Extraction rate, promote the purity of product, reduce production cost, described enzyme-assisted ultrasonic leaching is to be the ethanol aqueous solution of 70% with yellow rice flower raw material and concentration, accord...

Embodiment 2

[0026] According to Embodiment 1, in order to make the yellow pigment in the raw material meet the requirements of extraction and reduce the extraction cost, the raw material of yellow rice flower is a kind of flower bud and tiktok; in order to dissolve the cellulose of the raw material epidermis of yellow rice flower, make All the pigments inside are exposed to achieve the purpose of extraction, and the enzyme is cellulase.

Embodiment 3

[0028] According to Embodiment 1, in order to make the yellow pigment in the raw material meet the requirements of extraction and reduce the extraction cost, the described yellow rice flower raw material is a mixture of flower buds and catkins; in order to dissolve the cellulose in the yellow rice flower raw material epidermis, make it All the pigments inside are exposed to achieve the purpose of extraction, and the enzyme is cellulase.

Abstract

The invention relates to a pigment extraction technology, in particular to a method of extracting a natural edible pigment. The method comprises the following steps of firstly, extracting a yellow pigment of buddleja officinalis maxim by adopting enzyme-assisted ultrasonic wave so as to obtain filtrate a; secondly, concentrating the filtrate a to 0.25-0.5 time the volume, and extracting through a diphase water system so as to obtain an organic phase; lastly, absorbing and extracting the organic phase through a macroporous resin, concentrating a recovered solvent to obtain yellow liquid, and drying, sealing and packaging the yellow liquid to obtain a product. Through combination of three technologies, the extraction efficiency and the extraction rate of the yellow pigment of the buddleja officinalis maxim are greatly improved, the product purity is improved, processing steps are simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to pigment extraction technology, in particular to a natural food pigment extraction method. Background technique [0002] Huangfanhua is also known as "Xiaojinhua, Menghua, Buddleja officinalis Maxim, Buddleja officinalis Maxim, a shrub of the genus Buddleja officinalis Maxim, with a height of 1-4 Rice, the branchlets are slightly quadrangular, gray-brown; branchlets, leaves, petioles and inflorescences are densely covered with gray-white star-shaped short hairs, which belong to the shrub plant of the genus Buddleia in the genus Buddleia. The dried flower buds and inflorescences of the yellow rice flower, after being boiled in the folk, will get a yellow substance, and use the yellow substance to dye the rice, which can make the rice golden yellow and fragrant, which in turn can improve human immunity and stimulate the human body. effect of appetite. [0003] Studies have shown that the main components of the yellow substance o...
