Embodiment 1

[0021] Weigh the donkey-hide gelatin stock solution, mix it with water so that the substrate mass percentage concentration is 5%, the hydrolysis temperature is 50°C, the pH value is 8.5, the mass percentage concentration of the compound enzyme preparation is 2%, and the hydrolysis time is 3 hours; , Rice wine weight ratio 100:5:2 Add rock sugar and rice wine, mix well, use maltodextrin and β-cyclodextrin weight ratio 3:2 as wall material, wall material to core material mass ratio 1:2, embedding temperature Microencapsulate for 1 hour at 30°C; vacuum-dry at -0.09MPa to -0.04Mpa at 70-80°C to obtain donkey-hide gelatin powder. The compound enzyme preparation is prepared by compounding 2709 alkaline protease and Alcalase 2.4L alkaline protease at a weight ratio of 1:1.

Embodiment 2

[0023] Weigh donkey-hide gelatin stock solution, mix it with water so that the substrate mass percentage concentration is 7%, the hydrolysis temperature is 50°C, the pH value is 9.0, the mass percentage concentration of the compound enzyme preparation is 1.5%, and the hydrolysis time is 2 hours; , Rice wine weight ratio 100:4:1 Add rock sugar and rice wine, mix evenly, use maltodextrin and β-cyclodextrin weight ratio 2:1 as wall material, wall material to core material mass ratio 2:3, embedding temperature Microencapsulate for 1 hour at 30°C; vacuum-dry at -0.09MPa to -0.04Mpa at 70-80°C to obtain donkey-hide gelatin powder. The compound enzyme preparation is prepared by compounding 2709 alkaline protease and Alcalase 2.4L alkaline protease at a weight ratio of 1:1.

Embodiment 3

[0025] Weigh donkey-hide gelatin stock solution, mix it with water so that the substrate mass percentage concentration is 8%, the hydrolysis temperature is 55°C, the pH value is 8.5, the mass percentage concentration of the compound enzyme preparation is 3%, and the hydrolysis time is 4h; , Rice wine weight ratio 100:6:1 Add rock sugar and rice wine, mix evenly, use maltodextrin and β-cyclodextrin weight ratio 1:1 as wall material, wall material to core material mass ratio 1:1.5, embedding temperature Microencapsulate for 1 hour at 30°C; vacuum-dry at -0.09MPa to -0.04Mpa at 70-80°C to obtain donkey-hide gelatin powder. The compound enzyme preparation is prepared by compounding 2709 alkaline protease and Alcalase 2.4L alkaline protease at a weight ratio of 1:1.

Abstract

Belonging to the technical field of food, the invention discloses donkey-hide gelatin raw powder and its preparation method. The powder is a convenient product prepared by the following steps of: taking donkey-hide gelatin extract as the raw material and subjecting it to enzymolysis treatment by a biological composite enzyme, then adding rock sugar, yellow rice wine and other auxiliary raw materials, conducting microencapsulation treatment with maltodextrin and beta-cyclodextrin as wall materials, and carrying out vacuum drying, crushing as well as packaging. In the product, the molecular weight of 80% of low-molecular weight peptides is less than 2000 Dalton. Various amino acids are composed reasonably, thus being easy for the human body to adsorb. And the employed embedding technology and vacuum drying technology maintain the active substances and nutrients in donkey-hide gelatin to the utmost. The vacuum drying technology adopted in the method of the invention lowers the drying temperature, and also can prevent the loss of active substances and nutrients in the drying process. Thus, the product of the invention has improved quality and stability, as well as good dissolvability and fluidity.

Description

technical field [0001] The invention relates to the field of comprehensive development and application of animal protein, in particular to a convenient donkey-hide gelatin powder product and a preparation method thereof, belonging to the technical field of food. Background technique [0002] Donkey-hide gelatin has a long history in our country. It is a commonly used nourishing traditional Chinese medicine with many special effects. It is made from the skin of pigs, horses, camels and other miscellaneous skins. Since the Qing Dynasty, it has been made from black donkey skins. Donkey-hide gelatin has the functions of nourishing blood, nourishing yin, moistening dryness and stopping bleeding. It is clinically used for blood deficiency and chlorosis, dizziness and palpitations, muscle weakness, restlessness, insomnia, internal movement due to deficiency wind, cough due to dryness of the lungs, hemoptysis due to labor cough, hematemesis, hematuria, hematochezia, metrorrhagia an...
