Abstract

The invention provides a preparation method of donkey bone collagen powder, donkey bone powder and donkey bone oil. The preparation method comprises the following steps: (1) separating bones; (2) carrying out freezing; (3) crushing the bones; (4) carrying out preliminary degreasing to obtain crude bone oil; (5) performing drying and crushing to obtain crude bone meal; (6) performing secondary degreasing to obtain crude bone oil, combining the crude bone oil with the crude bone oil obtained in the step (4), and performing refining to obtain refined donkey bone oil; and (7) performing extractingto obtain refined bone meal. The donkey bone collagen powder disclosed by the invention is good in instant solubility, small in molecular weight, easy to absorb and capable of rapidly supplementing collagen lost from tissues, and is widely applied to the industries of cosmetics, sports beverages, medicines and health products. Meanwhile, the donkey bone oil prepared by the invention is light yellow and clear in color, contains a large amount of unsaturated fatty acids necessary for human bodies, and is wide in application prospect. In addition, the refined bone meal also contains rich minerals and a part of donkey bone collagen, and can be applied to the industries of feeds and chemical fertilizers.

Description

technical field [0001] The invention belongs to the field of deep processing of animal bone products, and in particular relates to a preparation method of donkey bone collagen powder, donkey bone powder and donkey bone oil. Background technique [0002] Influenced by the traditional health-preserving culture of "Ejiao", donkey raising and derivative products have become a pillar industry in Liaocheng. Traditional Ejiao is made from donkey skin, and there is currently no feasible way to use donkey bones. Most of them are processed at the primary level. way to deal with. [0003] Donkey bone, rich in collagen, minerals and unsaturated fatty acids, has the effect of nourishing kidney and nourishing yin, strengthening tendons and bones. At present, the extraction of donkey bone collagen is mostly carried out by high-temperature cooking, which consumes a lot of energy, produces a lot of waste, and pollutes the environment. Contents of the invention [0004] In view of this, t...
