Method for extracting ceramide from chestnut shells

Abstract

The invention discloses a method for extracting ceramide from chestnut shells. The method comprises the following steps: cleaning chestnut shells, crushing the cleaned chestnut shells, adding water with a weight of 3-5 times of the weight of the chestnut shells, adding lactic acid bacteria for fermentation, carrying out centrifugal separation on the obtained fermentation liquor, taking the clear liquor for later use, filtering and sterilizing the obtained clear liquor through a millipore filter membrane, and carrying out continuous chromatographic selection separation on the obtained filtrateto obtain the ceramide. According to the invention, the lactic acid bacteria are used for fermentation of the chestnut shells, and a large amount of ceramide substances can be secreted into the fermentation liquor, so that no derivatization process is needed, the operation is simple, the extraction is convenient, the fermentation period is short, the effect is quick, and the limitation by regionalclimate is avoided. The waste chestnut shells are turned into wealth, and resources are fully utilized. According to the process used for producing the ceramide, the solvent can be repeatedly used, the environmental influence is reduced, and the economic cost is reduced.

Description

technical field

[0001] The invention belongs to the field of fermentation industry, and in particular relates to a method for extracting ceramide from chestnut shells. Background technique

[0002] Chestnut, known as the "King of Dried Fruits", has another name called chestnut, big chestnut, and chestnut. Chestnut nuts are purple-brown, covered with yellow-brown hairs, or nearly smooth, with light yellow flesh, sweet and delicious taste. Chestnuts are suitable for both raw and fried food. Stir-fried chestnuts with sugar and roasted chicken are fragrant and delicious. They can be ground into powder, and can also be made into various dishes, cakes, canned food, etc. But people often discard chestnut shell when making processing, edible chestnut, cause waste.

[0003] Chestnut husk is the exocarp of chestnut. It has sweet, astringent and flat medicinal properties, and has the effects of reducing adverse reactions and stopping bleeding. In recent years, it has been discovered...
