Abstract
The invention relates to a method for preparing corn seed coat dietary fiber, which comprises the following steps of: crushing corn seed coats, performing ultrasonic treatment and microwave treatment on the crushed corn seed coats by using water as an extraction agent respectively, cooling the solution, adding a mixed enzyme preparation of alpha-amylase and protease into the solution, and performing enzymolysis on the solution for 20 to 50 minutes at the pH of between 4.0 and 6.0; and after the solution is filtered after the enzymolysis, washing the filter residue by using deionized water, concentrating the filtrate, removing protein from the filtrate and washing the concentrate by using alcohol, drying the two samples respectively, and performing ultra-fine pulverization on the two dried samples to obtain the corn seed coat dietary fiber. The yield of the dietary fiber prepared by the method reaches 87.4 percent; and the dietary fiber granules are fine and light yellow, have no special smell, and can be used as a dietary fiber nutrition enhancer of multiple food products.
Description
Technical field
The present invention relates to a kind of preparation method of dietary fiber, particularly relating to a kind of is the dietary fiber preparation method of raw material with the corn peel.
Background technology
Along with China's rapid economy development, great changes have taken place in people's diet structure.Yet, because diet structure is science not, food fiber intake deficiency causes the appearance of " ciril disease ", and hypertension, high fat of blood, diabetes, constipation, obesity, coronary heart disease etc. are all relevant with the intake deficiency of high-quality dietary fiber, and that gives people has healthyly brought serious harm.Coronary heart disease, hypertension, diabetic account for adultly more than 15% in the National urban, and are ascendant trend year by year.Dietary fiber is to keep the very important composition that the bodily fuctions runs well, and the nutritionist has confirmed the health-care effect of dietary fiber through deep research, is referred to as " the 7th nutrient ".
Dietary fiber is meant the summation of edible plants cell, polysaccharide, lignin and the related substances that can not be digested and assimilated by the human body endogenous enzymes, dietary fiber as the seventh-largest nutrient, not only have higher nutritive value, can also prevent numerous disease, essential to body metabolism.Itself does not contain heat dietary fiber, can improve the intestines and stomach function, can effectively regulate the human body functions of intestines and stomach, can be habitual constipation person and removes misery, gets rid of vivotoxin, promotes healthy.Have prevention constipation and the carcinoma of the rectum, reduction serum cholesterol, regulate blood sugar level, prevention gall stone, absorption sodium ion, hypotensive, fat-reducing and effect such as anticancer.
Corn is one of most important three generalized grain crops in the world today, and cultivated area and total output are only second to paddy rice and wheat, but its yield per unit area occupies the first, and corn has become grain, feed and raw material of industry dual-purpose crop.China is second-biggest-in-the-world Maize Production state, and present 80% corn is with the directly listing or directly consume through preliminary working of raw grain state, and the corn deep processing industry is very undeveloped.
China mainly concentrates on the production of feed and starch to the processing of corn.But for corn processing back byproduct---the research that corn peel utilizes again also seldom and is in quite low level, and a lot of enterprises only used as feed or discarded, cause the very big wasting of resources.Some composition of corn peel or component (as dietary fiber, corn lipopolysaccharides, maize voxel and luteole etc.) research also seldom or be in quite low level is rationally utilized.Corn peel is not treated, can only fill as a kind of energy in people's stomach and add thing, and human body is not had remarkable health-care effect.Corn peel is compared with other cereal crust, and not only dietary fiber content height, and its dry grinding gained crust is compared with wheat bran, rice bran, and phytic acid content is low, and is little to the adsorptivity of mineral elements such as calcium zinc, less to the nutrient absorption influence of human body.The corn peel dietary fiber can significantly reduce the cholesterol level in the blood, thereby reduces the incidence of disease of heart disease and stroke.
The method for preparing at present corn dietary fiber mainly contains: enzyme process, chemical method, enzyme process are in conjunction with chemical method etc.Because general chemical reagent can make the physiologically active of corn peel dietary fiber reduce, do not advocate corn peel is used chemical method, the method that tradition dietary fiber preparation technology adopts bronsted lowry acids and bases bronsted lowry solution to replace hydrolysis more is removed desizing and protein, but the local flavor and the color and luster of hydrolysis prods are relatively poor, product yield and quality are not easy control, and working properties is also had certain influence.
" preparation method of corn peel dietary fiber " invention fully rationally utilizes the corn resources advantage, accelerates the deep processing of cornstarch and accessory substance thereof, improves the corn comprehensive utilization ratio, can produce good economic benefits and social benefit.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of corn peel dietary fiber, Zhi Bei yellowish, the no special odor of dietary fiber particle exquisiteness, color in this way can be used as dietary fiber enriched dose of numerous food.
For achieving the above object, the present invention adopts following technical scheme: a kind of preparation method of corn peel dietary fiber, it is characterized in that, it is 10～60 orders that corn peel is pulverized the back particle size range, with water is extractant, solid-liquid ratio 1: 7～1: 20,40 ℃～65 ℃ of temperature, ultrasonic processing is 20～80 minutes under ultrasonic power 200W～600W condition; Under microwave 200W～800W condition, handled 1～4 minute again, be cooled to 45 ℃～65 ℃, add the AMS of 0.2% (w/w)～0.7% (w/w) and the mixing enzyme preparation of protease (ratio of AMS and protease is 3: 1～1: 3) in the feed liquid, enzymolysis is 20～50 minutes under pH4.0～6.0 conditions.After feed liquid behind the enzymolysis is filtered, the washing of filter residue deionized water, alcohol was washed after filtrate concentrated deproteinized, and two kinds of samples are dry respectively, and ultramicro grinding obtains the corn peel dietary fiber.The dietary fiber yield of being produced by above method reaches 87.4%.
It is 10～60 orders that corn peel is pulverized the back particle size range.
