Description

A kind of processing method of wheat bran dietary fiber
Technical field
The present invention relates to food processing technology field, more particularly to a kind of processing method of wheat bran dietary fiber.
Background technology
With the development of society, people's living standard increases substantially, there occurs huge for the diet structure of China resident Change, everyone daily grease consumption figure of city dweller in 2002 increased 44g by the 37g of 1992, and fatty function is than rising To 35%, exceed 30% upper limit of world health organisation recommendations, meanwhile, cereals food intake ratio only 47%, hence it is evident that low In 55-65% zone of reasonableness.The nutrition intake of this diet structure is unbalance, there is provided energy and fat it is too high, dietary fiber mistake Low, the prevention to some chronic diseases is unfavorable, particularly groups of people because work etc. reason, life it is irregular, cause diabetes, Cardiovascular disease, obesity, bowel cancer, constipation etc. are more and more common.Higher in this living standard, nutrient imbalance threatens body to be good for Under the situation of health, consumer begins to seek one kind to be adapted to modern life demand, be beneficial to nutrient balance, be wholesome Functional food, dietary fiber are exactly that act as the key player in this diet development history.Wheat bran is as a kind of high-quality meals Eat fiber source, in order to which high-quality dietary fiber is therefrom made, study accordingly it is long-standing, from simply directly using chemistry Method purifies, then to biological enzyme increasingly in fashion today, the research to wheat bran dietary fiber have accumulated countless food scholars, agriculture Product processing scholar and the painstaking effort of nutritionist, it is therefore necessary to search out a kind of high-quality wheat bran dietary fiber produced Technique, and shorten the distance of laboratory research and industrialized production.Meanwhile using wheat bran dietary fiber, be advantageous to improve agriculture The comprehensive utilization ratio of byproduct, its added value is lifted, there is huge economic benefit.The key for improving wheat bran is to remove wheat Unnecessary starch and protein and plant acid and desalinate its color in bran, the harsh feeling of mouthfeel reduces, and removes wheat bran In the impurity and peculiar smell that contain.Therefore mainly consider that appropriate process conditions remove above material in design process flow, with It is shallower to reach color, good mouthfeel, and the purity for increasing dietary fiber improves the recovery rate of dietary fiber.Chang Xianhui exists《It is more The enzyme method of fractional steps produces the research of wheat bran food fibre powder》Middle research contents includes, and probes into the optimal of wheat bran dietary fiber and carries Method is taken, the preliminary sense organ and edible quality for improving product;Influence of the food fibre powder to flour quality is studied, and carries out tradition Boiling product is tested, and determines coefficient optimum proportion and manufacture craft.To be laid the foundation for industrialized production, and develop meals fibre Tie up staple food products.
The content of the invention
The present invention lifts its added value, improves the sense organ of product and eat to improve the comprehensive utilization ratio of agricultural byproducts Quality, balanced diet trophic structure, there is provided a kind of processing method of wheat bran dietary fiber.
A kind of processing method of wheat bran dietary fiber, it is characterised in that completed by the following steps:
1), wheat bran cleaned, is cleaned, the impurity and starch being mixed into wheat bran are removed with scalping and dusting cover, then washed with clear water Fine impurities are gone, wheat bran and water are pressed 1:8-9 ratio is added in reaction vessel, is heated to 50-55 DEG C of 30-35 points of processing 10-15 minutes are boiled in clock, then heating;
2), step 1 gains are added to wheat bran mass fraction 0.5-0.55% alpha-amylase, digest 45- in 90-95 DEG C of constant temperature 50 minutes, 40-45 DEG C is cooled to, addition wheat bran mass fraction 0.1-0.12% lipase, 45-50 is digested in 40-42 DEG C of constant temperature Minute, 33-35 DEG C is cooled to, addition wheat bran mass fraction 0.2-0.23% neutral proteinase, 45- is digested in 33-35 DEG C of constant temperature 50 minutes, material is heated to seething with excitement, continues enzyme deactivation 20-25 minutes;
3), step 2 gained wheat bran washed to water without muddiness with cold water, add volume fraction for 10-15% by H2O2 with NaClO is with 1:The destainer of 2-3 ratios mixing, concussion processing 1-1.5 hours, then washed with cold water to water without muddiness;
4), by material through 2000-3000r/min centrifugal dehydration 4-5 minutes, dried in 80-90 DEG C to moisture content content to 5-8%, Dispense kept dry.
It is an advantage of the invention that:
A kind of processing method of wheat bran dietary fiber of the present invention, hot cooking create good for the hydrolysis of endogenous phytase Condition has the function that to remove phytic acid.Then heating is boiled, and plays a part of inactivating endogenous enzymes.The wherein mistake of lipoxidase It is living, the generation of the smell substances such as ketone, aldehyde can be reduced, makes product that there is good smell.The multienzyme method of fractional steps of the present invention extracts wheat The method of skin dietary fiber, i.e., according to the difference of different enzyme preparation optimum reaction conditionses, reaction condition gradient is designed, is realized Multienzyme stepwise discretization is completed in one reaction unit, hydrolysis result is improved, improves product purity, save energy consumption.This hair Bright to use hypochlorite and hydrogen peroxide composite decoloration, H2O2 has oxidisability, and NaClO has reproducibility, when two kinds of reagents During mixing, redox reaction occurs immediately, generates substantial amounts of singlet oxygen, material under the strong oxidation of singlet oxygen, Rapid to fade, positive effect is better than conventional discoloration method, and combinations color and lustre is in light milk yellow, meanwhile, the method is more conventional Research method it is quick, be advantageous to shorten the production cycle.Wheat bran after treatment, either from mouthfeel or smell all Take on a new look, and have more consumption, this is due to carry out the plant that boiling eliminates wheat bran and contained in itself in preparation process to wheat bran Acid, while after the effect softened, particularly ferment treatment, product is further purified.
Embodiment
The present invention is further illustrated below by specific embodiment.
