Problems solved by technology

[0003] At present, the methods for extracting silkworm chrysalis oil mainly include solvent leaching and solvent pressing, but these methods have certain defects.
Silkworm chrysalis is a high-protein, high-fat material with low crude fiber content and relatively soft texture, so it is difficult to extract oil by solvent pressing, and the yield of silkworm chrysalis oil is also very low.
The solvent extraction method is not affected by the softness and hardness of the oil texture. After the oil is properly pretreated and a suitable solvent is selected, the oil can be extracted. However, the current solvent extraction method generally uses dichloromethane, acetone, etc. Larger single solvent extracts silkworm chrysalis oil, which not only pollutes greatly, but also has low yield, which is unfavorable for industrialized production; Crude oil), but the demand for solvent is large and the consumption time is long

Abstract

The invention relates to a preparation method of silkworm-chrysalis compound oil micro-capsules. According to the preparation method of the silkworm-chrysalis compound oil micro-capsules, supercritical CO(2) extraction and gradient freezing crystallization are adopted so as to prepare high-quality silkworm-chrysalis compound oil; and a micro-encapsulation technology is further adopted so as to prepare the silkworm-chrysalis compound oil micro-capsules. The preparation method of the silkworm-chrysalis compound oil micro-capsules has the following beneficial effects: the preparation method is simple in production processes, high in degree of automation, and capable of rapidly extracting compound oil with extremely high alpha-linolenic acid content from the silkworm chrysalis oil. The compound oil extracted according to the preparation method is refreshing, natural, few in organic solvent residues, extremely high in alpha-linolenic acid content and stable in properties; and thus, the compound oil is capable of effectively preventing and treating hyperlipidemia, promoting hepatocyte regeneration, and preventing and treating non-alcoholic hepatic adipose infiltration.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for preparing silkworm chrysalis compound oil microcapsules. Background technique [0002] In the "Dictionary of Traditional Chinese Medicine", it is recorded as follows: silkworm chrysalis oil can cure malnutrition fever, weight loss, and thirst in children; silkworm chrysalis oil is rich in various amino acids, trace elements and n-3 and n-6 ​​series polyunsaturated fatty acids, especially containing Polyunsaturated fatty acids necessary for the human body. At present, the development and research of silkworm chrysalis oil is more focused on reducing plasma and cholesterol, improving liver function, increasing the production of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in the body, And it has the functions of adjusting blood lipid and anti-oxidation; at the same time, silkworm chrysalis contains a lot of amino acids, that is, the focus is on lipid-lower...
