Technique for producing edible ethyle ester type chrysalis oil using chrysalis crude-oil

Abstract

The invention discloses a process used for producing edible ethyl ester-typed silkworm pupa oil by silkworm pupa crude oil, comprising the main steps as follows: silkworm pupa crude oil extracted by organic solvent or squeezed and separated by machines is degummed, dehydrated and esterified; ethanol is recovered, glycerin and sulphuric acid are separated and washed; saturated fatty acids are removed and distilled; during the distillation process, the distillate with the temperature of 120-140 DEG C and the pressure of 1-5Pa is intercepted. The ethyl ester-typed edible silkworm oil produced by the process has good sensory index and the color thereof is buff; no crystals occur at zero DEG C; unsaturated fatty acid has high content; the acid value and peroxide value of the oil reach the edible standard, the quality of the product is good, the safety is high and no solvent remains; the process can be widely applied to the industries such as medicines, health-caring food, nutrition food, high-grade cosmetics and the like.

Description

technical field [0001] The invention belongs to the technical field of production technology of edible grade silkworm chrysalis oil technical background [0002] Silkworm chrysalis oil contains a variety of unsaturated fatty acids, the content of which is as high as 75%, of which the content of α-linolenic acid is more than 30%, the content of linoleic acid is about 7%, and the content of oleic acid is about 32%. It is worth mentioning that silkworm chrysalis oil It also contains a certain amount of odd-numbered carbon fatty acids C15 and C17. During the development of anticancer drugs, Dr. Mitsuhiro Numata found that odd-numbered carbon fatty acids have high anticancer activity, and odd-numbered carbon fatty acids are extremely important in land organisms. It is rare, which makes silkworm chrysalis oil valuable for development and utilization; the silkworm chrysalis crude oil that is commonly extracted by solvents or mechanically squeezed and separated is dark brown in colo...
