New method for removing cores of wild jujube

Abstract

The invention discloses a new method for removing cores of wild jujube, which comprises the following steps of: preparing pectinase and cellulase into complex enzyme solution, wherein the pectinase concentration of the solution is 30U / mL, the cellulase concentration of the solution is 10U / mL, and the pH value of the solution is 4.5 to 5.0; mixing the complex enzyme solution and the wild jujube cores in a solid-liquid ratio of 1:2-4, and performing enzymolysis for 2 to 4 hours at the temperature of between 45 and 55 DEG C; and taking out the wild jujube cores, cleaning, drying, and performing mechanical crushing to obtain complete wild jujube kernels. The enzymes are acted on the cell walls of the wild jujube cores, so that the wall cell cellulose and the middle lamella undergo enzymolysis of certain degree, and the cell wall structures are further subjected to breakage of certain degree; and the wild jujube cores are dried and then mechanically broken. Compared with the traditional mechanical core breakage, the method improves one-time core breaking rate, the core breaking rate is improved by nearly 50 percent, the integrity of the jujube kernels is kept, the quality of the product is greatly improved, meanwhile, mechanical core breakage is simpler, other equipment does not need to be increased, and the method is favorable for reducing equipment cost.

Description

Technical field [0001] The invention relates to a new method for removing the nucleus of wild jujube. Background technique [0002] Jujube seed is the dry mature seed of the plant Jujube nucleus, a common fruit Chinese medicinal material, which is rich in flavonoids, saponins, alkaloids, fatty acids and other chemical components. Flavonoids and fatty acids have sedative and hypnotic effects. Total saponins have anti-arrhythmic effects, improve myocardial ischemia, improve hypoxia tolerance, lower blood pressure and lower blood lipids. However, there is a layer of hard jujube kernels on the outside of wild jujube kernels. To extract wild jujube kernels for medicinal purposes, the wild jujube kernels must be broken first. [0003] The traditional process of nucleating nucleus to obtain sauerkraut kernels is to use a denucleating machine or to grind the nuclei. The general one-time nucleation rate is 40%-50%. If you increase the mechanical strength to increase the nucleation rate, th...

Problems solved by technology

[0003] The traditional process of extracting spiny jujube kernels is to use a denucleating machine or grinding to break the cores. The general rate of one-time nuclear breaking is 40%-50%. If the mechanical strength is increased to increase the rate of nuclear breaking, although the rate of nuclear breaking can be improved, the rate of core breaking can be improved. The broken jujube kernel will also increase significantly, which will greatly reduce the quality of the product
