In addition, the molecular weight of the donkey-hide gelatin peptide is mainly distributed between 180-2000, so that the donkey-hide gelatin peptide is easier to absorb by a human body.
Description
Technical Field
The invention discloses active small-molecule donkey-hide gelatin paste and a preparation method thereof, belonging to the field of deep processing of donkey-hide gelatin.
Background
The traditional donkey-hide gelatin is a gelatin block prepared by decocting and concentrating the skin of donkey of an equine animal, adding auxiliary materials such as soybean oil, rock sugar and the like, has the functions of enriching blood and stopping bleeding, and is a famous traditional Chinese medicine. The main components of the food are collagen, peptide and amino acid except for containing a small amount of trace elements, wherein the protein component accounts for about 80 percent. In the process of preparing the donkey-hide gelatin, the process of drying and blocking is the longest in time consumption, the greatest in difficulty and the highest in cost, which is also the important reason for the high price and difficult popularization of the donkey-hide gelatin. The cost expenditure of this section is of no value in terms of efficacy. The invention creatively innovates a non-valuable block making process by taking the traditional paste as a carrier, and reduces the production cost.
Meanwhile, the traditional donkey-hide gelatin blocks are hard, poor in taste and tedious to eat, and are important factors limiting the circulation of the donkey-hide gelatin blocks. Although some preparations such as donkey-hide gelatin syrup, donkey-hide gelatin oral liquid and donkey-hide gelatin cake are available, the dosage form is limited by the carrier, and the donkey-hide gelatin content is generally low, so that the efficacy is limited. The method disclosed by the invention has the advantages that the content of the donkey-hide gelatin solid is more than 40Brix, the donkey-hide gelatin solid is a viscous liquid paste, the donkey-hide gelatin solid can be instantly taken at any time and any place, and the problem that the traditional donkey-hide gelatin blocks are complicated to take is solved.
In addition, the macromolecular protein component in the donkey-hide gelatin accounts for 80 percent, so the donkey-hide gelatin is difficult to digest and absorb, namely 'nourishing and greasy and obstructing the stomach' indicated by the traditional Chinese medicine. Therefore, people with poor digestion function have difficulty in exerting due efficacy when eating donkey-hide gelatin, and the gastrointestinal burden is increased. This is because large protein molecules cannot be directly absorbed by the human body, and after entering the digestive system, they are first hydrolyzed into polypeptides by pepsin in the stomach, and then further hydrolyzed into small peptides or amino acids by trypsin, aminopeptidase, chymotrypsin, etc. in the intestinal tract, and then absorbed by the human body.
In recent years, many small-molecule peptides (3-15 peptides, molecular weight below 2000) have been found to have specific pharmacological activity. For example, pentapeptide (Tyr-Ile-Gly-Ser-Arg) has activity against cancer cell metastasis; the dodecapeptide (Ile-Tyr-Leu-Gly-Gly-Pro-Phe-Ser-Pro-Asn-Val-Leu-NH2) has immunity regulating and anticancer effects. The collagen is hydrolyzed into high-activity small molecular peptide in vitro, so that the utilization rate of the human body can be greatly improved, the activity is increased, and the physical burden is reduced.
Therefore, the preparation of the liquid paste form instant food and high-absorption active small molecular donkey-hide gelatin paste with low cost has important significance.
In recent years, some reports on the preparation of small-molecular donkey-hide gelatin peptides exist, but expensive donkey-hide gelatin blocks or donkey-hide gelatin juice are used as raw materials, different types of protease are used for catalytic reaction, and the molecular weight distribution is 200-10000 Da. Because of the problems of solubility, etc., the dosage forms are mainly peptide granules and peptide powder. For example:
the invention discloses a method for preparing liquid donkey-hide gelatin by an enzyme hydrolysis method (publication number is CN 1237421A). in the method, donkey-hide gelatin blocks are used as raw materials, after being dissolved by adding water, the donkey-hide gelatin blocks are hydrolyzed by papain, bromelain or ficin to prepare liquid donkey-hide gelatin oral liquid, but the molecular weight range is not mentioned, and the solid content is not increased.
The invention patent of mixture of active micromolecule donkey-hide gelatin and preparation method and application thereof (publication number is CN102499376B) discloses a method, which takes donkey-hide gelatin juice as raw material, adopts compound protease including proline protease to carry out enzymolysis on the donkey-hide gelatin juice to prepare zymolyte rich in small peptide, and the peptide sections are distributed between 200 and 3000Da and mainly between 200 and 1000. The method does not consider the control of flavor, does not control residual oil, and does not solve the problems of high cost and convenient taking.
The invention discloses a micromolecule donkey-hide gelatin pure powder tablet and a preparation method thereof (publication number is CN104107192A), which take expensive donkey-hide gelatin blocks as raw materials, add water, heat and melt the gelatin, then hydrolyze the gelatin by one or more of papain, bromelain, neutral protease, alkaline protease and collagen hydrolase, and finally obtain a finished product after drying and tabletting. The method does not relate to the control of exposed amino acid and residual grease, and does not solve the problems of high cost and convenient eating.
The invention discloses a preparation method of low-bitter donkey-hide gelatin oligopeptide (publication number CN107028176A), which is used for preparing the low-bitter donkey-hide gelatin oligopeptide by embedding the donkey-hide gelatin oligopeptide with sodium alginate and arabic gum microcapsules, but the taste of the donkey-hide gelatin oligopeptide is not changed substantially, and the problems of high cost and convenience in eating are not solved.
The invention discloses a preparation method of donkey-hide gelatin oligopeptide (publication number is CN103122363B), which takes donkey-hide gelatin stock solution as raw material, heats and stirs, adjusts pH, adds Alcalase2.4L FG hydrolytic proteinase for hydrolysis, and finally sprays and dries. The method adopts single enzyme for hydrolysis, the addition amount of the enzyme is large, the pH value needs to be adjusted in the reaction process, the reaction time is long, oil is removed by a filtration method, and the control of flavor and the control of cost are not considered.
The methods use colla corii asini blocks or colla corii asini juice as raw materials to prepare the small-molecular colla corii asini peptide, and the control of the proteolytic sites is not considered, so that when the common protease hydrolyzes the protein, sulfur-containing amino acid (cystine and methionine) and basic amino acid (lysine) are exposed, odor and ammonia smell are generated, and the small-molecular colla corii asini peptide is difficult to swallow and causes discomfort. If the amount of sulfur-containing amino acids and basic amino acids exposed during hydrolysis is avoided or reduced, the odor and ammonia odor can be significantly reduced, and the taste can be improved. At present, no report of preparing small molecular donkey-hide gelatin peptide by a method for controlling a protein hydrolysis site is found; moreover, the existing small-molecule donkey-hide gelatin peptides are all prepared into powder or tablet products, and no report of preparing small-molecule donkey-hide gelatin paste is found.
