Embodiment Construction

[0038] The present invention will be further described below in conjunction with specific embodiments.

[0039] 1. Preparation of p-coumaric acid arabinoxylan ester

[0040]1g (6.06mmol) of p-coumaric acid was added to the single-necked bottle, then 50mL of dichloromethane and a drop of DMF (catalyst) were added, stirred evenly, and 0.53mL (7.27mmol) of SOCl 2 Dilute with 10mL of dichloromethane and add to the constant pressure dropping funnel, under N 2 Under protection, slowly added to the reaction flask, then heated to reflux for 4h, the reaction solution became clear, and the solvent and excess SOCl were distilled off 2 , to obtain p-coumaroyl chloride and store it away from water vapor for later use.

[0041] Add 3.93g arabinoxylan (24.24mmol anhydroglycoside) and 160mLDMA into a three-necked flask, heat to 120°C, stir evenly until it dissolves, cool to room temperature, add 1.23mL (9.09mmol) triethylamine, and dissolve 6.06mmol P-coumaroyl chloride was diluted with 20...

Abstract

The invention discloses multifunctional araboxylan and a preparation method thereof, belongs to the field of natural high-molecular modification, and relates to a multifunctional polysaccharide antioxidant and a preparation method thereof. The preparation method comprises the following steps: grafting a small molecular antioxidant to araboxylan; making hydroxycinnamic acid react under the action of thionyl chloride to generate hydroxy cinnamoyl chloride; then, carrying out an esterification reaction on the araboxylan and the hydroxy cinnamoyl chloride under the action of triethylamine (acid-binding agent) to generate hydroxycinnamic acid araboxylan ester. The hydroxycinnamic acid araboxylan ester has high oxygen resistance and thickening performance, can be widely applied to the industries of foods, health care products and makeups.

Description

technical field [0001] The invention relates to a preparation method of a class of multifunctional polysaccharides, which can enhance the antioxidant and thickening ability of polysaccharides by grafting polysaccharides and antioxidants, especially the antioxidant and thickening abilities of water-soluble arabinoxylans, which can be applied to Cosmetics, food, health products and other fields. [0002] technical background [0003] Free radicals are currently identified as the most important endogenous aging factor. Therefore, anti-aging is to a large extent anti-free radicals and anti-oxidation. The research on antioxidants has always been a hot spot in the research of medicine, food, cosmetics and other industries. Natural polysaccharides have the characteristics of safety, no side effects, high efficiency, and rich sources, and have been widely used and researched. In the study of plant polysaccharides, it was found that many plant polysaccharides have a wide range of bi...
