Problems solved by technology

It is difficult to separate oil and pigment in the oil-soluble method; although the supercritical CO2 extraction method has the advantages of low extraction and purification temperature, no solvent residue, and effective avoidance of product oxidation, it requires high equipment requirements. It is difficult to implement in industry; the one-time investment of microwave and ultrasonic assisted extraction equipment is relatively large; the solvent method is simple to operate and has a large degree of industrialization, and almost all the existing capsanthin production in my country adopts the organic solvent extraction method

Embodiment 1

[0032] 1. Optimization of the extraction conditions of capsanthin

[0033] (1) Selection of extraction solvent

[0034] At the same temperature, use the same volume of acetone, diethyl ether, petroleum ether, n-hexane, ethyl acetate, and absolute ethanol to reflux extraction, extract a certain quality of chili powder, extract for a certain period of time, and place the extract in a drying box to evaporate After the solvent is dry, dilute it with acetone to 100mL respectively, use acetone as a reference solution, and measure the maximum absorption peak with a spectrophotometer. The results are shown in figure 1 .

[0035] from figure 2 It can be seen that the maximum absorption wavelength of capsanthin extracted from six solvents in acetone solution is 460nm. Under the same conditions, the extraction rate of capsanthin obtained by using acetone as the extraction solvent was the highest, followed by absolute ethanol, and the extraction rate of capsanthin was the lowest when...

Abstract

The invention belongs to the technical field of pigment extraction and discloses a method for analyzing a capsanthin change rule in a fresh pepper pretreatment process. The method includes the following steps that: the influence of pepper freshness on a capsanthin extraction rate is analyzed through a single-factor experiment; the influence of drying temperature, drying time and fruit water content on the content of capsaicin in a fresh pepper drying process is systematically analyzed, the change of the content of the capsanthin is determined, relevant relations between the capsanthin and thetemperature, time and water content in the fresh pepper drying process are searched, and an optimal regulation and control measure is found out, so that a basic theoretical guidance is provided for establishing a reasonable pepper processing technology; the influence of pepper crushing granularity on the capsanthin extraction rate is analyzed through a single-factor experiment; and a fresh pepperpretreatment method is confirmed.

Description

technical field [0001] The invention belongs to the technical field of pigment extraction, and in particular relates to a method for analyzing the change rule of capsanthin in the pretreatment process of fresh peppers. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Capsanthin is the bright red part of red pepper. It is currently the best natural pigment recognized internationally, without any spicy taste, and its color intensity is 10 times that of other pigments. According to relevant laws and regulations in our country, capsanthin can be widely used in medicine, food, cosmetics, and feed industries. The United States, Britain, Canada, Japan, Spain, Mexico, and Southeast Asian countries also widely use capsanthin as an additive in medicine and natural food. In addition, capsanthin has been proved by modern science to have nutritional and health functions such as preventing and treating cardiovasc...
