Description

A kind ofly be applicable to that the wheat embryo of suitability for industrialized production pastes the method for work

Technical field

The present invention relates to the processing method of wheat embryo, specifically is a kind of preparation method that is applicable to that the suitability for industrialized production wheat embryo is stuck with paste, and characteristics are that wheat embryo pastes and passed through extrusion pressing puffing process.

Background technology

Wheat embryo is as the byproduct of wheat flour processing factory, resource is very abundant, the wheat embryo amount that can be used for developing every year can reach ten thousand tons of 30-50, along with wheat embryo bud nutrient is worth and Study on Functional Properties, the scientific research personnel pays close attention to the application study of wheat embryo more and more both at home and abroad, makes the development and utilization of wheat embryo become a big focus of wheat deep processing.For a long time, most flour mills join used as fodder in the wheat bran to the wheat embryo of separating again, packing was sold after general employing was leached and extracted wheat-germ oil or direct baking in the commercial process, all be the preliminary working that belongs to wheat embryo, make that this precious resources fails to obtain fully, reasonable use.

Summary of the invention

Existing problem during purpose of the present invention is handled at wheat embryo just and propose a kind ofly be applicable to that the wheat embryo of suitability for industrialized production pastes the method for work, be on the basis of comprehensive above wheat embryo extrusion method pluses and minuses, designed a kind of new manufacture craft.The wheat embryo powder stay in grade of utilizing the inventive method to produce, fragrant and sweet smell is outstanding, and mouthfeel, local flavor are splendid.

The objective of the invention is to be achieved through the following technical solutions:

Of the present inventionly be applicable to that the wheat embryo of suitability for industrialized production pastes the method for work, is characterized in that: comprise following processing step:

A, get raw material: 30-45%, wheat embryo 45-58%, ingredient powder 8-12% by weight, wherein said auxiliary material is taken from any one in shelled peanut, sesame, walnut kernel or the mung bean;

B, pulverizing: rice or wheat and ingredient powder are put into pulverizer, pulverized 3-8 minute with the speed of 1440-2880r/min, afterwards with the raw material that crushes under 45-65 ℃ of temperature equilibrium water conten 1-2 hour;

C, premixed: step 2 gained powder and wheat embryo are put into mixer, mixed 3-5 minute with the speed of 40-60r/min, be mixed into uniform wheat embryo premixed powder;

D, extrusion: the premixed powder that mixes is carried out the extrusion granulation in twin-screw extruder, extrusion speed is 200-300r/min, and extrusion temperature is 160-255 ℃, and mould outlet is 0.05-0.2mm;

E, the expanded and oven dry in dry back: expanded good wheat embryo grain enters the expanded and oven dry in back in the expanded all-in-one of oven dry, and modulation moisture is to 4-8%;

F, pulverizing: meet the powder that order is counted requirement modulating the wheat embryo grain by crushing system, being ground into, the order numerical control is built in the 40-80 order;

G, mixing: single bi-tristearin of getting milk powder, the 0.1-0.4% of guar gum, the 3-10% of black sesame powder, the 0.5-1.5% of white granulated sugar, the 3-8% of maltodextrin, the 25-35% of wheat germ powder body weight 12-18% is allocated with the wheat embryo powder and is mixed;

H, metering, packing.

The present invention's advantage and effect compared to existing technology is:

1, the easy expanded characteristics of this technology utilization rice meal and wheat flour are mixed with wheat embryo, overcome wheat embryo and are difficult for expanded shortcoming;

2, expandedly carry out in twin (double) screw extruder, floor space is little;

3, the wheat embryo of extrusion has microcellular structure, makes water-fast wheat-germ oil and dietary fiber all have very strong water dispersible, has improved the water dispersible of wheat embryo;

4, brought into play the effect that improves local flavor and powder physical behavior with rice meal or wheat flour mixture puffing, powder just can reach thick mouthfeel and wheat embryo local flavor short reconstituting in the time;

5, the order numerical control system of pulverizing after the granulation can have been adjusted the shortcoming of the caking of uniting after powder reconstitutes effectively;

6, the wheat embryo of this explained hereafter is stuck with paste stay in grade, and fragrant and sweet smell is outstanding, has the distinctive mouthfeel of rice and wheat embryo and local flavor;

7, wheat embryo is the elite of wheat seed, not only be rich in nutritional labelings such as protein, fat, minerals and vitamins, but also contain multiple composition with special physiological activity, as glutathione, linoleic acid, leukotrienes, choline and VE etc., be a kind of protein sources of natural high-quality.
