Problems solved by technology

[0005] In addition, due to the fact that sesamin is almost insoluble in water, sesamin is not easily absorbed by the human body, and there are defects such as low solubility of active ingredients, low bioavailability, and poor drug stability after being made into preparations, and it is also difficult to make ordinary food Health products and medicines are widely used

Abstract

The invention relates to a preparation method for water-soluble seamin. The preparation method comprises the following steps: selecting sesame seed meal as a raw material; performing secondary enzymatic hydrolysis, water washing, solvent extraction, active carbon treatment, cyclodextrin inclusion, membrane separation and freeze drying technology to obtain a water-soluble sesamin product of which the sesamin content is not lower than 65 percent by weight and the sesamin recovery rate is higher than 95 percent. The method is simple and convenient in steps; moreover, the conventional method using a toxic reagent, namely, diethyl ether or n-hexane is abandoned, so that the finished product quality of the sesamin product is ensured well, the water-soluble sesamin product is obtained directly, and subsequent production and utilization of the sesamin product are facilitated well.

Description

technical field [0001] The invention relates to a preparation method of water-soluble sesamin. Background technique [0002] Sesame, also known as Sesamum indicum (Sesamum indicum), is the seed of the annual erect herb flax, which is found in tropical regions and some temperate regions of the world. Sesame is one of the main oil crops in China and has high application value. The oil content of its seeds is as high as 55%. Sesame oil can be obtained by pressing, also known as sesame oil, linseed oil, and sesame oil. Sesame meal is a by-product of sesame oil extraction, mainly composed of sesame protein, and also contains a certain amount of lignans such as sesamin. In actual production, sesame oil manufacturers will produce a large amount of sesame meal after oil extraction. These sesame meal are generally used as waste or animal feed, and some are even directly disposed of as garbage, which not only pollutes the environment, but also greatly wastes the sesame meal. Contai...
