Abstract

The invention discloses a method for extracting sweet almond oil and protein thereof from sweet almond, which is characterized in that: sweet almond is dried and smashed to be arranged inside an enzymolysis tank, calculated at W / V, deionized water is added with the solid-liquid ratio of 1:(3 to 5), after being maintained for 10 minutes at the temperature of 85 to 90 DEG C, the mixture is inactivated and cooled, the pH value is adjusted to 7 to 9, composite of protease and cellulose which is 1 to 3 percent of the weight of the sweet almond is added, enzymolysis is carried out for 1 to 3 hours at the temperature of 35 to 55 DEG C, then the temperature is increased to 85 to 100 DEG C to be maintained for 10 minutes, the mixture is inactivated and cooled, and the inactivated enzymolysis liquid is centrifuged to obtain an upper layer of clear oil, i.e. the sweet almond oil; the upper clear liquid after being centrifuged is obtained, the pH value is adjusted to 4.5, then the upper clear liquid is centrifuged again, the sedimentation layer is obtained to be washed by water, and the collected sediment is frozen and dried to obtain almond protein powder. With the method, the sweet almond oil can reach 78.6 percent, the content of the extracted protein can reach 91.6 percent, and the fat is 6.2 percent. The method has wide application value.

Description

field of invention

[0001] The invention relates to the technical field of oil and protein extraction. Specifically, the present invention relates to the technical field of extracting sweet almond oil and protein thereof from sweet almonds. Background technique

[0002] Almonds are the kernels of the deciduous tree plants of the Rosaceae family, apricot or apricot. According to the difference in fruit flavor, they can be divided into two types: sweet almonds and bitter almonds. my country is rich in almond resources, mainly produced in Xinjiang, Gansu, Shaanxi, Shanxi and other places. In addition to eating, almonds also have broader development prospects. They are rich in protein, fat, sugar, carotene, B vitamins, vitamin C, vitamin P, calcium, phosphorus, iron, selenium and other nutrients. The content is 24%-27%, the almond oil content is as high as about 50%, and the almond is rich in nutrition. The protein content in every 100g almond is 24g, and its protein is rich in ...
