Embodiment Construction
[0015] In order to better understand the technical solution of the present invention, the following describes the embodiments provided by the present invention in detail.
[0016] Embodiments of the present invention provide a method for extracting small molecule active substances from sunflower discs, comprising the following steps:
[0017] (1) Pre-crushing of raw materials: In order to optimize the extraction process and improve the extraction rate of the product, the whole sunflower disc is crushed into 3-4 mesh coarse particles by a wood flour grinder;
[0018] (2) Dynamic extraction: using a dynamic micro-pressure extraction tank for extraction. This equipment is mainly used for micro-high pressure extraction of micro-blocks or coarse particles with water as the medium in a stirring state. The stirring device is more conducive to the sufficient active ingredients of the material. At the same time, it can avoid the loss of active ingredients caused by the damage of high t...

The invention discloses a method for extracting micromolecular active substances from sunflower calathide. The method is characterized by comprising the following steps of (1) precrushing raw materials into 3-4-mesh particles; (2) dynamically extracting slurry at micropressure; (3) carrying out gradient enzymolysis by using a compound enzyme, i.e., heating for sterilizing, then, cooling to 50 DEG C, and adding 100U / g of xylanase to carry out enzymolysis for 1-2h, then, adding 150U / g of pectinase to carry out enzymolysis for1-2h, and next, adding a NaOH solution to regulate the pH value to 6.0, and adding 3200U / g of papain to carry out enzymolysis for 2-3h; (4) carrying out membrane separation, filtering and filling into a clear liquid storage tank; (5) carrying out double-effect vacuum energy-saving concentration, wherein the first-effect vacuum degree and temperature are respectively controlled at 0.06MPa below zero and 70-80 DEG C, and the second-effect vacuum degree and temperature are respectively controlled at 0.08MPa below zero and 50-60 DEG C; (6) centrifuging at high speed, carrying out spray drying; (7) packaging a finished product. Due to the implementation of the technical scheme, the method has the following technical effects of low cost and high extraction rate of effective components; in addition, an extract is small in molecular weight and easy to absorb and utilize.
Description
technical field [0001] The invention belongs to a method for extracting peptides or proteins, and in particular relates to a method for extracting small-molecule active substances from sunflower disks by using biological enzymatic hydrolysis technology. Background technique [0002] Sunflower dish, that is, the sunflower dish after removing the sunflower seeds, is rich in nutrients, containing 7%-9% of crude protein, 6.5%-10.5% of crude fat, 15%-18% of crude fiber, and 2.4%-3% of pectin. Nitrogen-free extract (mainly starch) is about 40%, and the content of crude protein and nitrogen-free extract can be comparable to that of grain. According to the analysis of Jilin Agricultural University, the total amino acid and essential amino acid content of sunflower disc are 7.96% and 3.7%, respectively, and It also contains more glutamic acid and glycine. [0003] Sunflower dishes are rich in various nutrients, but their utilization rate is low, and they are mainly used for pig feed...
