Embodiment Construction

[0012] The embodiments of the present invention are described in detail below. A production method of wood frog egg amino acid chelated calcium food, the method comprises the following steps:

[0013] (1) Drying: put the collected frog ovum into a ventilated drying box and dry to constant weight at 55°C;

[0014] (2) crushing: crushing to 30 mesh;

[0015] (3) Extraction: using CO 2 Supercritical degreasing to prepare defatted frog egg powder; supercritical carbon dioxide solvent extraction pressure is 32MPa, temperature is 35°C; carbon dioxide flow rate is 20Kg / hour, extraction time is 6 hours;

[0016] (4) Enzymolysis: use papain 15 with an activity of 600,000 U / g and neutral protease 15 with an activity of 120,000 U / g to enzymatically hydrolyze for 3 hours at a temperature of 52°C and a pH value of 6 to make it Decompose into polypeptides and amino acids, etc., heat to above 80°C for 10 minutes, inactivate protease, filter, and prepare enzymatic hydrolysis solution;

Abstract

The invention relates to a preparation method of rana chensinensis frogspawn calcium amino acid chelated food, belonging to the agricultural product processing technique. The preparation method comprises the following steps: taking frogspawns as raw materials, drying, powdering, extracting and degreasing to obtain purified degreased frogspawn powder; under mild conditions, preparing frogspawn amino acid compound hydrolyzed solution by enzymolysis of various proteolytic enzymes; and then taking calcium chloride as a calcium source to prepare rana chensinensis frogspawn compound calcium amino acid chelated food by the chelation. In the method, waste frogspawns with abundant nutrition are prepared into healthcare food so as to spread the application range of the frogspawn. The method has thecharacteristics of reasonable and simple process and high utilization ratio of the frogspawns.

Description

technical field [0001] The invention belongs to the technical field of agricultural product processing, and mainly relates to a production method of Rana egg amino acid chelated calcium health food. Background technique [0002] The commonly referred to as forest frog refers to the scientific names of Chinese forest frog (Rana temporariachensinensis) and Heilongjiang forest frog (Rana amurensis). . At present, the most valuable thing on Rana is the dried oviduct of its female frog, which is used as medicine. It is called "Toad Oil" and "Rana Oil", and the Cantonese call it "Snow Haga", which is a traditional and effective animal medicine. , is a specialty of Northeast China. It is recorded in "Compendium of Materia Medica" and "Pharmacopoeia of the People's Republic of China" that toad oil is warm in nature, returns to the lung and kidney meridian, and has the effects of nourishing kidney and essence, nourishing yin and moistening lung, nourishing deficiency and reducing f...
