Technique for preparing almond peptide sports beverage and separating almond oil by enzyme process

Abstract

The invention belongs to a production method of almond peptide sports beverage and almond oil, and particularly relates to a technique for preparing bitter almond peptide sports beverage and separating the almond oil by enzyme process, solving the problem that the existing almond product can not utilize the almond comprehensively, wastes the almond oil, and also brings bad influence to a health-care product. The technique for preparing almond peptide sports beverage and separating the almond oil by enzyme process takes the bitter almond as raw material, adopts acid protease to degrade the protein, separates the almond oil and the almond peptide solution under the condition of refrigerating and centrifuging, and mixes the almond peptide solution and cane sugar with citra-ic acid and beta-cyclodextrin to obtain the almond peptide sports beverage. The technique has the benefits that: the bitter almond protein is degraded into oligomeric polypeptide, the mixed polypeptide beverage has stable form, the flavor and mouth feeling are easily accepted by a human body, and simultaneously the almond oil with good quality and easy refining is obtained.

Description

technical field [0001] The invention relates to a production method of almond peptide sports drink and almond oil, in particular to a process for enzymatically preparing bitter almond peptide sports drink and separating almond oil, that is, a process of using bitter almonds as raw materials and using protease to degrade almonds The protein, thereby accelerating the dissolution of oil in almonds, refrigerated and centrifuged to separate the almond oil and the peptide solution, to prepare a soluble peptide mixture with better thermal stability, and then use it as the mother liquor to develop the almond peptide beverage. Almond peptide, sucrose, citric acid, and cyclodextrin are blended into almond peptide sports drink, which belongs to the field of food biotechnology and also belongs to the field of health product production technology. Background technique [0002] Almond is the seed kernel of apricot or apricot, a plant of the Rosaceae family. It has the functions of reducin...

AI Technical Summary

Problems solved by technology

The existing oil preparation mainly includes pressing method and solvent extraction method. These two methods first use mechanical force and solvent to separate the oil from the protein. The protein is denatured to varying degrees during the processing process. Serious waste of protein resources when used as feed or fertilizer

Although the almond oil extraction process can solve the problem of protein destruction by supercritical extraction, the method has expensive instruments and equipment, high production costs, and fails to fully utilize the protein contained in the almond meal after producing almond oil.

[0005] Chinese patent application No. 200810236513.7 discloses a kind of "almond peptide nutrition product and its preparation method". The almonds are directly beaten, and then the almond protein is degraded into polypeptides with the help of protease, and then concentrated to make capsules, tablets and almond peptide powder; the patent uses It is papain or alkaline protease, these two proteases are not very suitable for hydrolyzing almond protein; and the health care product is a mixture of fatty acid and polypeptide aqueous solution; since the fat content of almond is about 60%, the product contains more fatty acids during processing It is easy to oxidize and deteriorate during storage and storage, which undoubtedly brings unnecessary troubles to the processing and storage procedures. In addition, the product has a high oil content, resulting in poor palatability of the product.

Therefore, in essence, the waste of almond oil is formed, which has a bad influence on the health care product.
