Embodiment 1

[0034]Fresh mirabilis (obtained from Jining Bailixin Grass Industry Co., Ltd.) was dried under reduced pressure at 0.01MPa at a temperature of 50°C for 2 hours, and the dried jasmine was crushed to 40 mesh. The crushed jasmine and β-zeolite (obtained From Ningbo Jiahe Company) mixed according to 2:1 weight ratio, then add 2.0% by weight chitosan based on the weight of β-zeolite to granulate, use ethanol / water (1:1) mixed solvent to carry out the granulation after granulation Distillation-extraction, concentrating the extract under reduced pressure at a temperature of 60°C to obtain a concentrated solution containing jasmine pigment. Tested by HPLC, the pigment extraction efficiency is 62.1%. Add 0.2% by weight of the stabilizer represented by the formula (I) to the concentrated solution, place it in a natural environment for 30 hours, and measure its ultraviolet spectrum curve.

Abstract

The invention provides a method for extracting a mirabilis jalapa flower pigment and a composition containing the mirabilis jalapa flower pigment. The method includes the steps that fresh mirabilis jalapa flowers are dried for 1-20 h at the temperature of 30-80 DEG C; the dried mirabilis jalapa flowers are smashed to be in 10-80 mesh; the smashed mirabilis jalapa flowers are mixed with zeolite, and then granulating is performed; a mixed solvent is used for extracting particles after granulation; an extracting solution is concentrated to obtain a concentrated solution containing the mirabilis jalapa flower pigment. With the method, the mirabilis jalapa flower pigment which is good in taste and flavor can be obtained quite efficiently and stably.

Description

technical field [0001] The invention belongs to the technical field of food pigments, and in particular relates to a method for extracting jasmine pigments and a composition containing jasmine pigments. Background technique [0002] Natural pigments mainly refer to pigments obtained from natural resources, mainly pigments extracted from animals, plants or microorganisms. Natural pigments, especially natural plant pigments, have the advantages of high safety, natural color, etc., and also have certain nutritional effects and pharmacological effects, and have gradually replaced synthetic pigments as an important part of food additives. [0003] Mirabilis is an Oleaceae plant, an evergreen shrub, and a high-grade spice plant. The leaves, flowers and roots of Mirabilis have medicinal value. Purple jasmine flowers are bright in color and non-toxic, so jasmine red pigment is a very high-value natural food coloring. In addition, compared with other common types of purple pigment...
