Description
Technical field
The present invention relates to a kind of silkworm and mulberry compound oil grease microcapsule and preparation method thereof, belong to technical field of agricultural product process.
Background technology
China is the first in the world silkworm and mulberry big producing countries, and the sericulture there region is wide, aboundresources.Over the past thousands of years, the main body output that silk is produced as silkworm and mulberry, its position never shakes.In recent years, along with modern science and technology to the deepening continuously of silkworm and mulberry The Study on Resources, people excavate out the multiple use of silkworm and mulberry resource in fields such as food, medicine and chemical industry.The Reform Movement of a silkworm and mulberry resource innovation utilization quietly rises.
Silkworm chrysalis oil and Fructus Mori oil all are rich in polyunsaturated fatty acid, have blood fat reducing, blood sugar lowering and improve effects such as liver function, are of high nutritive value.Because degree of unsaturation is high, silkworm chrysalis oil and Fructus Mori oil are easy to oxidative rancidity under natural environment, local flavor variation not only, and nutritive value is also had a greatly reduced quality.
Microcapsule technology is a kind of physically trapping technology, is with macromolecular material solid or liquid core to be wrapped up and the tiny capsules of formation diameter 1～500um.Micro encapsulation can protect core to make it exhausted with ambient light, temperature, air bound, keeps the biological activity of core, prevents the destruction and the loss of nutrient substance, thereby prevents or delay the generation of product oxidation deterioration.Simultaneously, microcapsule technology can also be covered the inherent local flavor of product itself.Therefore, this technology can the improved products local flavor.In addition, microcapsule technology makes that the form of product is diversified more, is more convenient for processing accumulating and application, has widened product purpose.
Supercritical CO
2Fluid extraction technology is a new extractive technique that develops rapidly both at home and abroad in recent years.This technology is with low energy consumption, low-residual, environmental protection and in food industry, find broad application.Research shows, with supercritical CO
2Fluid extraction technology extracts silkworm chrysalis oil and the Fructus Mori oil that obtains, and color and luster is yellowish, and fragrant odour can reach directly edible requirement.This provides the approach of a simple possible for the deep development of silkworm and mulberry resource.
At present, also do not occur supercritical CO
2Fluid extraction technology and microcapsule technology Combined application are in the technical field of the exploitation of silkworm and mulberry resource oil and fat product.
Summary of the invention
