Lutein extraction and treatment process

Abstract

The invention discloses a process for extracting lutein. The process for extracting lutein includes the process steps of crushing materials, granulating powder, extracting lutein, and removing residues in vacuum. The process for extracting lutein also includes Including the raw material fermentation process before the material crushing step and the freezing treatment process after the vacuum removal process; the raw material fermentation process ferments the raw materials in the fermentation equipment to obtain fermented materials, and the freezing treatment process uses the lutein paste obtained by the vacuum removal process The body is subjected to low-temperature freezing treatment, and then the inspection and packaging of the lutein paste are carried out. The lutein extraction and processing technology of the present invention can efficiently release the lutein in raw materials, improve the long-term storage stability of lutein products, improve the utilization rate of raw materials, reduce production costs, and improve product stability and oxidation resistance.

Description

technical field [0001] The invention relates to a substance extraction method, in particular to an extraction and processing technology of lutein. Background technique [0002] Naturally extracted lutein is bright in color, non-toxic and harmless, has good anti-oxidation, prevents yellow retinal disease, and can prevent blindness caused by muscle degeneration. It is widely used in food, beverage, medicine, cosmetics, feed Various industries such as additives have been widely used and have a large market space. [0003] Marigold is the main raw material for technological extraction of lutein. The existing industrial extraction methods of lutein all use marigold flowers as raw materials to extract lutein to meet industrial needs. The existing process for extracting lutein from marigold flowers is roughly as follows: marigold flower harvesting, enzymatic hydrolysis, dehydration, drying, granulation, low-temperature extraction, lutein extract, packaging and other technological ...

AI Technical Summary

Problems solved by technology

Although the existing extraction process can basically meet the needs of industrial production, the existing process has the following deficiencies: First, the existing extraction process uses enzymatic hydrolysis to process the marigold flower raw material, which cannot make the marigold flower The efficient decomposition of raw materials releases most of the lutein components, which makes the extraction efficiency of lutein low and the utilization rate of raw materials low; second, the existing extraction process takes the lutein extract after vacuum removal as the final product. Packaging inspection, because lutein is easily oxidized, it cannot efficiently maintain the stability of lutein, which reduces the content of lutein in the product and is easy to oxidize, which is not conducive to improving product quality and long-term storage effect
