Problems solved by technology

But the present cold pressing method prepares peanut oil, does not have the fragrance of peanut oil, has reduced people's acceptance, and peanut oil yield is low and causes peanut powder residual oil rate height (reaches more than 20% usually), and lipid content height causes peanut powder to be used in Insufficient water solubility in beverages, etc., poor product stability
Although other methods can be used to further reduce the residual lipid in peanut flour, this will obviously lead to cumbersome production process and increased cost

Abstract

The invention discloses a method for obtaining peanut oil with soft and refined fragrance and high-quality protein powder simultaneously, and belongs to the technical field of food processing. The problem that in existing hydraulic-type peanut oil making, the content of residual oil is high is effectively solved by adopting a gradient pressure increasing hydraulic squeezing method, the oil yield is increased by about 13%, and then application of hydraulic squeezing in industry is promoted. In addition, the obtained peanut oil with the soft and refined fragrance has the inherent smell and taste of peanut oil, is free of abnormal smell, light in color and luster, clear, transparent, low in acid value and high in VE content and oxidation stability and contains rich unsaturated fatty acid, sterol, wheat germ phenol, phospholipids, choline and the like; the peanut protein powder obtained through the method is low in residual lipid and high in nitrogen soluble index, and a beverage prepared from the peanut protein powder is good in stability.

Description

technical field [0001] The invention relates to a method for simultaneously obtaining soft and fragrant peanut oil and high-quality protein powder, and belongs to the technical field of food processing. Background technique [0002] Peanut is the fourth vegetable oil in the world, accounting for about 14% of the world's annual oil production. The oil content in peanuts is as high as 44%-58%, most of which are unsaturated fatty acids, especially the essential linoleic acid content is very rich. The content of protein in peanut is 24%-34%, the digestibility reaches 90%, contains 8 kinds of amino acids necessary for human body, is the third plant protein source in the world, and can supply about 11% of the world's demand. So peanuts are a good source of protein. [0003] The residue after peanut kernels are dried and crushed can be made into peanut powder. Peanut powder is rich in protein, trace elements, etc. It is widely used in food production fields such as baked goods, ...
