Process for storing and processing walnuts

Abstract

The invention discloses a process for storing and processing walnuts. The process comprises the following steps: S1, picking out diseased walnuts from dry walnuts; S2, removing walnut shells, grading, screening, and removing impurities; S3, drying walnut kernels; S4, packaging the walnut kernels; S5, storing the walnut kernels; and S6, processing the walnut kernels. The process has the benefits as follows: a storage process of drying, vacuum packaging and refrigerating is adopted instead of a processing process of frying, boiling or the like of the walnut kernels, causing the loss of the nutrient content of the walnut kernels before storage, so that the quality guarantee period of the walnut kernels can be prolonged and the loss of the nutrient content of the walnut kernels cannot be caused; the process is simple, low in cost and easy to realize; and the stored walnut kernels are processed, so that the quality guarantee period of a product is further prolonged and the added value of the product is increased at the same time.

Description

technical field [0001] The invention relates to the technical field of food processing technology, in particular to a walnut storage and processing technology. Background technique [0002] Walnuts are widely distributed in my country, with many varieties and rich resources. Walnuts have the effect of strengthening the brain and improving intelligence, and are rich in nutritional value. They can delay the aging of cells, prevent the decline of memory, and enhance the vitality of cells. They have been praised by more and more people. [0003] Walnut kernels have high water content and high oil content, and are easily oxidized and deteriorated during storage. At present, walnuts eaten as nuts are dried and stored after being picked. Although this preservation method is simple, the dried walnuts Not only part of the nutrients are lost, but also dry walnuts are prone to quality deterioration caused by oil oxidation after being stored for a period of time. Although processing m...
