Problems solved by technology

In addition, donkey skin, the main raw material for donkey-hide gelatin production, is easily polluted by microorganisms in nature. After fermentation and corruption, it will generate alkaline volatile basic nitrogen, which will cause abnormal taste when taken, which is difficult for consumers to accept. This problem has not been solved so far. effective solution

Abstract

The invention relates to instant donkey-hide gelatin powder and a preparation method thereof. The donkey-hide gelatin powder is a product obtained by heating and dissolving the finished product of donkey-hide gelatin in water, adding a certain amount of Tween-20 and sucrose fatty acid ester-13 according to a certain ratio, adding a proper amount of sweetener into the mixed solution, and drying and crushing the mixture under vacuum at a low temperature. The finished product keeps the original active ingredients and color and luster of the donkey-hide gelatin and shortens dispersion time from conventional 154s to 16s, so that the instant dissolving property of the donkey-hide gelatin powder in water is greatly improved and the inherent fishy smell of the donkey-hide gelatin is effectively removed. The method has the advantages of low equipment investment, simple and feasible process, stable product performance, eating convenience and high economic benefit and is an ideal method for producing the instant donkey-hide gelatin powder.

Description

technical field [0001] The invention belongs to the field of preparation of donkey-hide gelatin powder, in particular to an instant donkey-hide gelatin powder and a preparation method thereof. Background technique [0002] Donkey-hide gelatin is a treasure in the treasure house of the motherland's medicine. It is rich in collagen, polypeptides and various amino acids. It is a blood-tonifying drug commonly used in traditional Chinese medicine. However, traditional donkey-hide gelatin is mainly processed into a certain specification of donkey-hide gelatin after a long process, which must be heated and stewed when taking it, which brings great inconvenience to users. However, when the traditional donkey-hide gelatin powder is prepared with hot water, the melting speed is slow, it is easy to agglomerate, the dispersibility is low, the instant solubility is poor, and the sensory quality is poor. [0003] Using donkey-hide gelatin as the main raw material, combined with other tra...
