The invention provides a flaxseed meal dietary fiber preparation method and application thereof.The flaxseed meal dietary fiber preparation method comprises the following steps that firstly, flaxseed meal pulp is subjected to high-power pulse microwave pretreatment, after vacuum drying, bacillus subtilis K6 is inoculated for solid-state fermentation, then double enzymolysis is conducted through amylase and protease, and the flaxseed meal dietary fiber is obtained; soluble dietary fibers and insoluble dietary fibers are extracted, the insoluble dietary fibers are subjected to compound modification through rutin and betaine, and the soluble dietary fibers are extracted through adsorption and purification of composite surface imprinted microspheres. The method obviously improves the yield and purity of the soluble dietary fibers in the flaxseed meal, the activity function of the insoluble dietary fibers is obviously enhanced after the insoluble dietary fibers are subjected to composite modification, and the flaxseed meal can be used for developing functional food or health care products. The method disclosed by the invention is green, environment-friendly, stable in process and suitable for large-scale production, and the comprehensive utilization value of the flaxseed meal is effectively improved.

The invention relates to the field of protein extraction technology and multi-scene application, in particular to a high-functionality flaxseed protein-polysaccharide natural co-extract with good color and luster and a preparation method and application thereof. The method comprises the following steps: performing subcritical extraction on flaxseed cakes, squeezing the flaxseed cakes at low temperature / proper temperature to obtain degreased flaxseed cakes, crushing and screening the degreased flaxseed cakes to obtain degreased flaxseed meal powder, efficiently dissolving out protein and polysaccharide in the flaxseed meal powder through alkali dissolution synchronous double-frequency ultrasonic circulating treatment, and centrifuging to obtain supernate. A membrane separation device and a double-frequency ultrasonic device are connected in series through a pipeline to form a circulating system, obtained protein-polysaccharide supernate is treated through the system, and the protein-polysaccharide supernate is separated through the synergistic effect of key parameters such as membrane molecular size, ultrasonic power and ultrasonic intermittent time. The effect that the protein-polysaccharide supernate is subjected to concentration and intermittent ultrasonic modification at the same time can be achieved, a highly concentrated solution is finally obtained, and the concentrated solution is freeze-dried to obtain the flaxseed protein-polysaccharide natural co-extract. Compared with the existing single high-purity flaxseed protein, the flaxseed protein-polysaccharide co-extract prepared by the method has good color and excellent emulsibility, foamability and gelling property.

The invention provides a flaxseed processing method. The flaxseed processing method comprises the following steps: firstly, carrying out cleaning and surface treatment on a flaxseed raw material, and then separating flaxseed hulls and kernels by adopting a multi-stage separation technology; carrying out superfine grinding on the separated flaxseed skin, and extracting the flaxseed gum through the cooperation of composite enzymolysis and a physical field; performing low-temperature squeezing and degreasing on the separated flaxseed kernels, performing complex microbial inoculant solid-state fermentation modification on the obtained degreased flaxseed meal, and then performing graded extraction to obtain modified proteins with different functional characteristics; and compounding the extracted flax gum with the modified protein, adding an antioxidant, and preparing the composite product through a multi-mode drying technology. Various modern food processing technologies are organically integrated, all links are closely connected, a complete flaxseed comprehensive processing technology system is formed, the extraction efficiency of all active ingredients is improved, and the functional characteristics and stability of a final product are remarkably improved.

The present invention discloses flaxseed meal natto and a preparation method thereof, and relates to the technical field of food processing, the flaxseed meal natto is prepared from the following raw materials by weight: 16%-24% of flaxseed meal, 76%-84% of soybeans, and bacillus natto powder accounting for 0.4%-0.8% of the total weight of the soybeans and the flaxseed meal. According to the flaxseed meal natto and the preparation method thereof, 16-24% of flaxseed meal and 76-84% of soybeans are mixed according to a specific weight ratio to serve as a fermentation substrate, polyphenol substances rich in the flaxseed meal and volatile nitrogen-containing compounds generated in the fermentation process are subjected to a Schiff base reaction, and the flaxseed meal natto is obtained. The method effectively reduces the unacceptable ammonia odor in the traditional natto, endows the linseed product with special oil crop fragrance, controls the inoculum size of the bacillus natto powder to be 0.4-0.8% of the total weight of the soybean and the linseed meal, and combines the process conditions of fermentation at 34-43 DEG C for 18-26 hours to obtain the linseed natto. And the bacillus natto maintains proper metabolic activity under a carbon source and a nitrogen source provided by a proper amount of linseed meal.

The invention provides a broiler chicken raising method based on nutrition regulation and environmental stress induction, and belongs to the technical field of livestock breeding, and the broiler chicken raising method comprises the following steps: dividing a raising cycle into four stages of 1-14 days old, 15-28 days old, 29-35 days old and 36-45 days old according to time, and performing nutrition regulation and environmental induction on the four stages, feed containing flaxseed meal and fish oil is fed at the 29-35-day-old stage, choline and betaine are added, periodic mild cold stress treatment is combined, and unsaturated fatty acid is promoted to be deposited into muscles; 80% limited feeding is carried out at the 36-45-day-old stage, meanwhile, a yeast extract, L-glutamine and a flavor enhancer composed of betaine and allicin are supplemented, the content of flavor substances such as inosinic acid and glutamic acid is effectively increased, and the flavor of the broiler chickens is remarkably improved. Meanwhile, muscle fibers are refined and oxidative damage is relieved by reducing the feeding density, adjusting illumination, prolonging the free-ranging time and the like.
