Abstract

The invention provides primary walnut pulp and a production method thereof. The primary walnut pulp is prepared from raw materials of walnut kernels and pure water through pulping, enzymolysis, oil taking and standardization; and through detection, the product has the protein content of more than or equal to 2.5 percent, the fat content of more than or equal to 2.6 percent and the polypeptide content of more than or equal to 18mg/ml. The production method comprises the following steps of: preparing walnut pulp, performing enzymolysis, centrifuging to take oil, and performing secondary enzymolysis; adding pure water for standardization; and homogenizing feed liquid, separating impurities by using a self-discharging disc centrifuge, performing ultra high temperature short-time sterilizationtreatment, cooling to the temperature below 35DEG C, and performing sterile filling to obtain the final product. The obtained product is white in color and thick in walnut flavor, contains nutrient components such as walnut protein, linoleic acid, linolenic acid and walnut phosphatide, and is rich in walnut polypeptide with high bioactivity, does not contain cholesterol or lactose; the bioavailability of walnut protein is greatly improved; and the product has high stability and meets the consumption requirements of people on nature, health and nutrition.

Description

1. Technical field [0001] The invention relates to a beverage, which belongs to a vegetable protein beverage, in particular to a walnut puree and a production method thereof. 2. Background technology [0002] With the development of modern society and the continuous improvement of people's living standards, the consumption of vegetable protein beverages continues to increase. A vegetable protein functional drink integrating naturalness, health and nutrition will be more popular with consumers. [0003] Walnuts have attracted much attention because they are rich in nutrients such as walnut oil, walnut protein, and walnut lecithin. At present, the main products developed include walnut dew, walnut powder, walnut oil, amber walnut kernel and other snack foods. However, the puree directly processed from walnut kernels has the disadvantages that the proportion of fat and protein is uncoordinated, which is not conducive to human body absorption. 3. Contents of the invention ...
