Problems solved by technology

The asparagus extract in the prior art is obtained by grinding and extracting asparagus solution through a grinder. In order to improve the extraction rate of algal polysaccharide, active protein and phycobilierythrin in asparagus, high temperature is also used Hot water extraction method, but the extraction rate of active protein and phycobilierythrin obtained by this extraction method is low and the physiological activity is not good, which is not conducive to practical application

Embodiment

[0011] (1) Add solvent, first rinse the asparagus, put it in an oven to bake to remove water, then crush the asparagus, and choose an appropriate amount of asparagus powder and add three times the weight of deionized water to form asparagus mustard solution;

[0012] (2) Low-temperature pulverization, the step is to place the above solution in an ultrasonic pulverizer for cyclic pulverization, the output vibration frequency is 20 to 45KHz, the ambient temperature of the extraction is lower than 40°C, and the pulverization time is 60 Up to 120 minutes, the maximum output power is 1100W. Through the high-energy ultrasonic waves of the ultrasonic pulverizer, the solid particles of asparagus can be crushed into small particle powders. The average particle size of the powder can be in the order of microns or The ultrasonic power can be adjusted to make the average particle size of the powder reach the nanometer level, and the chemical properties of the solution are stable under thi...

Abstract

The invention relates to a method for improving antioxidant component content in asparagus schoberioides kunth extract. The method comprises steps that: extraction is controlled under a low environmental temperature below 40 DEG C; asparagus schoberioides kunth solution circular pulverizing is carried out by using a supersonic pulverizer, wherein an output oscillation frequency of the supersonic pulverizer is 20 KHz to 45 KHz, and a pulverizing time is 60 to 120 minutes, such that chemical propertied of the asparagus schoberioides kunth is stable; the solution is delivered through a filteringnet, such that impurities are removed through filtering, and asparagus schoberioides kunth extract is obtained. With the method provided by the invention, red phycobiliprotein content in the schoberioides kunth extract provided by the present invention is higher than that of prior arts. Therefore, antioxidant capacity of the asparagus schoberioides kunth extract is improved.

Description

technical field [0001] The invention relates to a method for extracting antioxidants from asparagus, in particular to a method for increasing the antioxidant components of asparagus extract. Background technique [0002] The alias of asparagus is also known as Qiaoweiya, Gracilaria or sea dragon. It belongs to the algae of Rhodophyta, Euerythrophyta, Cedaraceae, and Asparagus. It is a large-scale algae that grows in the middle and lower parts of the intertidal zone. Algae, its appearance is reddish brown slightly greenish, the size is about (15 to 20) 3 Cubic centimeters, the body is upright and can be cylindrical, flattened forked or laterally divided. There are about 100 species in the world, which are mainly distributed in isothermal and tropical regions including India, Indonesia, mainland China, Taiwan and Japan; asparagus contains Rich in sugars and proteins, the main chemical composition of sugars is algal polysaccharide, which is one of the main algae for producing...
