Healthcare product taking rana chensinensis bone as raw material for enhancing bone mineral density and preparation method thereof

Abstract

The invention discloses a healthcare product taking rana chensinensis bone as a raw material for enhancing bone mineral density and a preparation method thereof. The preparation method comprises the following steps: (1) adopting alkaline protease for performing enzymatic hydrolysis on rana chensinensis bone for 4.5h at 45 DEG C, wherein the enzyme dosage is 2.6wt% and the volume ratio of material to liquid is 1:30, performing enzyme deactivation, deproteinization and alcohol precipitation overnight treatment on the solution in turn after the ending of the enzymatic hydrolysis, lastly, collecting an alcohol sediment sample and drying, thereby acquiring rana chensinensis polysaccharide; (2) taking bone of gadus and crushing, thereby acquiring the gadus bone meal; and (3) uniformly mixing the rana chensinensis polysaccharide, the gadus bone and vitamin D at mass ratio of 30000:10000:1. The invention has the beneficial effects that (1) an enzymolysis method is adopted for extracting, the extracting condition is mild, the extraction ratio is high, the damage to the main ingredients is less, the product is rich in active precursors of CABP factors and vitamin D, the extractive is pure natural and the function of enhancing the bone mineral density is obvious and (2) the compound formula of rana chensinensis polysaccharide and gadus bone can boost the calcium absorption.

Description

Technical field [0001] The invention relates to a health product and a preparation method thereof, in particular to a health product using Rana temporaria bone as a raw material to enhance bone density and a preparation method thereof, belonging to the technical field of health products. Background technique [0002] Forest frog is a rare frog species that integrates food, medicine and health care. [0003] Wood frog bones have a high calcium content, with a calcium to phosphorus ratio of 2:1, which is equivalent to the calcium to phosphorus ratio of human bones, and is rich in collagen. [0004] The wood frog bone is not only rich in calcium, but also rich in protein-bound calcium that is not easy to lose in the kidneys, high-efficiency calcium absorption promoting factor CABP, and active precursors of vitamin D to promote intestinal calcium absorption. It is suitable for human absorption and has good properties. Calcium supplement function. [0005] At present, the processed produc...

Problems solved by technology

[0005] At present, the processed products of Rana are mainly Rana oil, and the utilization of Rana and male frogs after oil removal is still very little, and the processing and utilization of Rana bones is even less
