A kind of walnut meal compound nutrition powder and its preparation process

Abstract

The invention discloses walnut meal composite nutrition powder and a preparation technology of the walnut meal composite nutrition powder. The preparation technology of the walnut meal composite nutrition powder comprises the steps that (1) pearl barley powder and walnut meal powder serve as main raw materials, extrusion processing is carried out on the raw materials through a bulking machine under the conditions that the extrusion temperature is 150DEG C-170DEG C, and the screw speed is 540-580r / min, and pearl barley and walnut powder extruded materials are obtained; (2) the extruded materials are smashed to form powdery materials with the specification of being larger than 100 meshes, the powdery materials are placed into a homogenizer, sucrose and water are added, high-pressure homogeneity processing is carried out under the conditions that the pressure is 20-25MPa, and the temperature is 70-80DEG C, then, composite probiotics inoculated fermentation processing is carried out on the materials to form walnut meal composite fermentation liquid, and spray drying processing is carried out on the walnut meal composite fermentation liquid to obtain the walnut meal composite nutrition powder. The walnut meal composite nutrition powder and the preparation technology of the walnut meal composite nutrition powder have the advantages of being simple in processing technology, low in manufacturing cost, capable of making full use of the nutrition complementary advantage of the raw materials, capable of achieving all nutritional functions of the walnut meal raw materials, good in quality of products, good in taste of the products, rich in nutrient of the products, stable in quality and performance of the products and the like.

Description

technical field [0001] The invention relates to a walnut meal composite nutritional powder and a preparation process thereof, belonging to the technical field of walnut meal nutritional powder processing. Background technique [0002] Walnut meal is a processing by-product produced when walnut kernels are used to process walnut oil. At present, there are few related studies on the development of deep processing of walnut meal, a by-product of walnut oil processing. The Chinese patent document application number is 200710017281.1 once disclosed a technical scheme titled "a method for making walnut polypeptide powder". Using walnut meal as raw material to make walnut polypeptide powder, the main method of this technical scheme is to grind the walnut meal, extract walnut protein, then enzymolyze the walnut crude protein, centrifuge, take the supernatant, and dialyze the supernatant , to remove impurities and macromolecular compounds, then concentrate the obtained dialysate, an...

AI Technical Summary

Problems solved by technology

Obviously, this technical solution not only has the problems of complex manufacturing process and high processing and manufacturing costs, but also has the problem of not being able to make full use of walnut meal

In this technical scheme, due to the adoption of processes such as taking supernatant and dialysis supernatant, this not only greatly increases the processing cost, but also wastes many useful nutrients of walnut meal

Therefore, the existing deep processing technology of walnut meal is still not ideal.
