Formula and extraction process of composite natural green pigment

Abstract

The invention discloses a formula and an extraction process of a composite natural green pigment. The composite natural green pigment is extracted from raw materials by taking clear water as a mediumand a physical method without adding of any chemical substance, and the problems of fading and color change caused by illumination and air oxidation of a chlorophyll green pigment in the prior art aresolved. In order to achieve the purpose, the formula of the composite natural green pigment is prepared from 35 grams of gardenia, 15 grams of butterfly peas and 1500 grams of water, wherein the weight of raw juice is 64%-67%, and the weight is 10% by weight after concentration; 15 grams of butterfly peas and 35 grams of gardenia (or 30 grams of honeysuckle and 20 grams of butterfly peas) are poured into 1500 grams of water, and the mixture is boiled with big fire; a cover is put on, the boiling continues for 10 minutes with a small fire, uncovered standing is executed for 20 minutes after fire stopping, and 100-mesh sieving is executed; the boiling continues with big fire until 1 / 3 of the original volume is left b, and then the boiling is executed with small fire to reach a thick state;and natural precipitation is executed for at least 60 minutes, and the upper-portion pure part is taken and charged into a pastry bag, extruded into a sterilized refined oil bottle and refrigerated for later use.

Description

technical field [0001] The invention relates to the field of food pigments, more specifically, to a formula and extraction process of a composite natural green pigment. Background technique [0002] Natural colors are food colors obtained from natural sources. Pigments mainly extracted from animal and plant tissues and microorganisms (cultivation), among which vegetable colorants account for the majority. Natural pigments not only have the function of coloring food, but also a considerable part of natural pigments have physiological activity. [0003] Natural pigments derived from roots, stems, leaves, flowers, fruits, animals, microorganisms, etc. of natural plants. Edible pigments are called edible natural pigments. From the perspective of the amount added, the proportion of food pigments in food is very small. For products, beverages, wines, cakes, candies, medicines, etc. are a few thousandths, a few ten thousandths or even a few hundred thousandths. Although natural ...
