Problems solved by technology

This patent makes effective use of corn germ meal and increases the added value of corn germ meal. However, in the production process of instant corn germ meal, the corn germ meal is simply pretreated, crushed, homogenized, and spray-dried to make a brewable For beverages, the germ meal still contains starch, which will greatly reduce the dissolution stability of corn germ powder, making it easy to precipitate during the dissolution process of corn germ powder, and easy to agglomerate and agglomerate after dissolving in water. The tonality is poor, and at the same time, the refining particle size is 200 mesh, which greatly reduces the palatability of the corn germ powder, making the entrance of the corn germ powder sandy, affecting the sensory quality of the corn germ powder, and affecting consumer acceptance

specific Embodiment approach

[0030] The present invention will be further described below in conjunction with the examples, but not limited thereto.

[0031] The corn germ meal in the embodiment adopts the corn germ meal after the corn germ oil is extracted from the Chinese patent application whose publication number is CN101507452A, the water content is 10.93%, and the middle temperature α-amylase in the embodiment is purchased from Shandong Longda Biological Engineering Co., Ltd., Enzyme activity 3000u / ml.

[0032] The equipment used in the embodiment, pulp slag self-separation refiner is purchased from Shanghai Tiangang Machinery Manufacturing Co., Ltd., model is TGM-100; Colloid mill is purchased from Shanghai Beigong Colloid Mill Manufacturing Co., Ltd., model JM-50; The drying machine was purchased from Shaanxi Great Wall Chang Food Industry Co., Ltd., model GZ-5.

Embodiment 1

[0034] A kind of production technology of instant corn germ powder, comprises steps as follows:

[0035] 1. Raw material pretreatment: screen the corn germ meal to remove impurities, wash with clean water 3 times for second removal of impurities, and soak the washed corn germ meal and water at a weight ratio of 1:3 for 2.5 hours;

[0036] 2. The corn germ meal soaked in step 1 is placed in the pulp and slag self-separation refiner for beating according to the weight ratio of corn germ meal and water of 1:4, and the pulp and slag are separated at the same time to obtain a corn germ meal slurry. The pulp after the separation of the pulp and residue is added with water in a ratio of 1:2 by weight of the pulp and water, and the pulp and residue are separated at the same time to obtain the secondary corn germ pulp, and the primary corn germ pulp and the secondary corn germ pulp are combined to prepare corn germ pulp, and all the prepared corn germ pulp passed through a 100-mesh sie...

Embodiment 2

[0057] A kind of production technology of instant corn germ powder, comprises steps as follows:

[0058] 1. Raw material pretreatment: screen the corn germ meal to remove impurities, wash with water: 2 times for second removal of impurities, and soak the washed corn germ meal and water at a weight ratio of 1:4 for 2.0 hours;

[0059] 2. The corn germ meal soaked in step 1 is placed in the pulp and slag self-separation refiner for beating according to the weight ratio of corn germ meal and water of 1:3, and the pulp and slag are separated at the same time to obtain a corn germ meal slurry. The pulp after the separation of pulp and residue is beaten with water according to the weight ratio of pulp and water of 1:1, and the pulp and residue are separated at the same time to obtain secondary corn germ pulp, and the primary corn germ pulp and secondary corn germ pulp are combined to prepare corn germ pulp, and all the prepared corn germ pulp passed through a 90-mesh sieve.

Abstract

The invention relates to a production process of instant maize germ powder. The instant maize germ powder is prepared through raw material preprocessing, beating, enzymolysis, enzyme inactivation, colloid milling, sterilization, high-pressure homogenization and spray drying by taking maize germ meal as a raw material; the enzymolysis is carried out by adding medium-temperature alpha-amylase accounting for 0.2%-0.4% of the dry weight of the maize germ meal, and the starch hydrolysis DE value (Dextrose Equivalent value) of maize germ meal slurry which is subjected to enzymolysis is controlled between 18% and 22%; the prepared homogenized maize germ meal slurry achieves the easiness for the spray drying, and a finished product does not absorb moisture, so that the dissolution stability of the maize germ powder is enhanced, the deposition has small possibility of appearing in the dissolving process, and the maize germ powder is not caked and agglomerated when being dissolved in water; and the additional value of maize germ meal is increased. The instant maize germ powder obtained through the method disclosed by the invention achieves the protein content more than 23%, is in a faint yellow color and is fast in dissolution; and the dissolved instant maize germ powder is uniform in state and achieves the product dissolution time less than 27 seconds without any unpleasant odor.

Description

technical field [0001] The invention relates to a production process of instant corn germ powder, which belongs to the technical field of corn deep processing and food processing. Background technique [0002] my country is a large country of corn production. With the development of corn oil enterprises in recent years, there are a large number of corn germ meal resources with rich sources and low prices. After oil extraction, almost all the nutrients in corn germ remain in the germ meal. Corn germ, only It accounts for about 12% of the total mass of the grain, but its nutritional value is very high. It concentrates about 20% of the protein, 84% of the fat and 83% of the minerals in the corn grain. Corn germ meal is the residue after extracting corn oil from corn germ, the main by-product of corn germ oil extraction, and a high-nutrient substance mainly composed of corn fiber and protein. Among them, the mass fraction of crude protein is generally 23% to 25%, and the biologi...
