Embodiment Construction

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] 1. Experimental materials and instruments

[0029] Experimental materials and equipment: Oat β-glucan (content>75%) was purchased from Zhengzhou Linuo Biological Technology Co., Ltd.; tea polyphenols (content 98%) was purchased from Changsha Aiyin Biological Products Co., Ltd.; MD44-14 dialysis The bag (the molecular weight cut-off is 1.4kDa) was purchased from Union Carbide Corporation; the atomic force microscope was purchased from Veeco Precision Instrument Co., Ltd.; the Spectrum 100 Fourier transform infrared spectrometer was purchased from the United States PerkinElmer Instrument Company.

[0030] Pretreatment of oat β-glucan: mix oat β-glucan with water, stir at 80°C to dissolve completely, dialyze with running water for 24 hours, and then dialyzed with distilled water for 24 hours (to remove small molecules in the solution, To avo...

Abstract

The invention discloses a beta-glucan-tea polyphenol compound and application thereof. The compound is prepared by a the following steps of: adding a water solution of beta-glucan and a water solution of tea polyphenol or an activated monomer into a dialysis bag; placing a dialysis device in a phosphate buffer, the pH of which is 3-7 and ionic strength of which is 0.5-0.3 mol / L, and dialyzing at 20-60 DEG C until balance is achieved to obtain the compound. The beta-glucan-tea polyphenol compound prepared by the method has stronger oxidation resistance than independent beta-glucan or tea polyphenol, has synergism action on the cleaning capability of superoxide anions within a certain concentration range, can be used for preparing antioxidant agents and has good development and application prospects in the filed of food preservation. The beta-glucan-tea polyphenol compound can also be used for preparing antioxidant foods or medicines and has good development and application prospects inthe fileds of health foods and medicines.

Description

Technical field [0001] The invention relates to a compound, in particular to a β-glucan-tea polyphenol compound, and an application of the compound. Background technique [0002] As a kind of soluble dietary fiber, β-glucan is widely present in bacteria, yeast, fungi and higher plants (such as oats, barley, rye, wheat, etc.), mainly in the form of cellular structural components (such as cell walls). Modern medical research has shown that β-glucan has multiple functions such as regulating the body's immunity, anti-tumor, and lowering blood sugar, blood lipids and cholesterol. It has attracted widespread attention in the food and medical fields. [0003] Tea polyphenols is a general term for a class of polyhydroxy phenolic compounds in tea, which can be divided into flavanols, hydroxyl-[4]-flavanols, anthocyanins, flavonoids, flavonols and phenolic acids, etc. Among them, flavanols are mainly flavanols, and flavanols are mainly catechins. Catechins account for about 60-80% of the t...
