Abstract
The invention provides a process for preparing yam powder slag dietary fabrics, which consists of the steps of fermenting, rouging, alkalizing, hydrolyzing, decolorizing, extruding, drying, squeezing, puffing and disintegrating.
Description
Affiliated technical field
The invention belongs to the preparation method of food, particularly be rich in the preparation method of cellulosic food.
Background technology
Rhizoma Dioscoreae esculentae dietary fiber is as a kind of pure natural dietary fiber, and is very extensive in food production processing industry application.It is directly edible that it can make capsule, also can be used as a kind of raw material or the additive of food, adds in bread, noodles, biscuit, cake, candy and the various pot foods, makes the product institutional framework stable, reduces moisture loss, prolongs shelf life.Rhizoma Dioscoreae esculentae dietary fiber also can be used as the health food of specific group except that as the food additives, after the people is edible, and imbibition in human body alimentary canal, the wriggling of promotion stomach excretes the various toxin in the ight soil, diseases such as prevention constipation, hemorrhoid.Simultaneously, it can delay the absorption of glucide, and diabetes are had certain therapeutic action.In addition, imbibition under one's belt after it is eaten by the people makes the people produce satiety, reduces the absorption of human body to other nutrients, makes people not produce overnutrition.Dietary fiber mainly is present in the byproduct potato slag of sweet potato processing, potato slag fiber content height, and fiber texture is good, and mouthfeel is good, can be processed into high-purity, high-quality, high added value, broad-spectrum dietary fiber low in calories.Preparation method for edible cellulose of sweet potato powder dross, people such as the Zhou Hong of Hu'nan Prov. Crops Research Inst. are in the Hunan agricultural sciences first phase in 2003, the accessory substance potato slag that uses after sweet potato is extracted starch is disclosed, add water and enzyme preparation by impurity elimination, oven dry and after pulverizing, protein and syrup are separated, concentrate by super-filtering method, in concentrate, add organic solvent deposition, its drying precipitate, pulverized 80 mesh sieves and promptly obtain water-soluble Rhizoma Dioscoreae esculentae dietary fiber.But these documents all do not have to disclose in detail concrete ins and outs.
Summary of the invention
The purpose of this invention is to provide a kind of convenient and practical method for preparing edible cellulose of sweet potato powder dross.
Technical scheme of the present invention is that a kind of preparation method of edible cellulose of sweet potato powder dross is characterized in that:
A. the impurity elimination of fermenting: the remaining sweet potato granulated slag of producing starch is poured in the fermentation vat, add starch factory and produce the remaining wintercherry of starch, mixed proportion is that per hundred kilograms moisture 70% sweet potato granulated slag slurry is blended into wintercherry 50-70 kilogram, stirred 5-10 minute, 10-30 ℃ following spontaneous fermentation 20-48 hour, isolate starch and other materials in the sweet potato dregs, go out wintercherry water and can use again next time fermenting the screenings suction filtration, sweet potato granulated slag behind the suction filtration cleans, and impurity elimination, press filtration to pH value are neutral
B. alkalization hydrolysis: the sweet potato granulated slag that cleans press filtration is poured in the stirring reaction pot, add clear water in 1: 10 ratio of dried sweet potato dregs weight, ratio in dried sweet potato granulated slag weight 6% adds NaOH, stir then and heat 30-85 ℃, continue alkalization in 2-4 hour, add acid and be neutralized to pH value 6.5-8 normal temperature preservation 8-12 hour, filter-press dehydration;
C. decolouring: will handle the sweet potato granulated slag through preceding operation and insert in the bleaching cement pit, add 15-30 ℃ of hot water mediation temperature, the content that adds dried sweet potato granulated slag weight 2% is that the concentration of 2% ClO 2 bleaching liquid and dried sweet potato granulated slag weight 0.2% is that 30% hydrochloric acid is done promoter, stirred 10-15 minute, it is neutral keeping 20-30 ℃ of decolouring bleaching of potato residual-slurry water temperature to wash in 6-12 hour to pH value;
D. extruding oven dry: use the press filtration of gas blowout filter press to the moisture 20-30% of potato slag the product of step C gained, add dryer and keep 75-80 ℃, oven dry is to moisture 16-17%;
E. expanded: with the crude fibre extruder of oven dry, the control temperature is at 160-180 ℃ of extrusion slabbing thing;
F. pulverize: the tablet after expanded is pulverized the 80-100 order with common pulverizer, pulverize the 200-300 order with micronizer then and get required dietary fiber.
In technology of the present invention, at first isolate sweet potato granulated slag interior starch and other materials with the fermentation impurity elimination, get rid of protein residual in the granulated slag and sugar part with alkalization hydrolysis, washing process again, decolour with ClO 2 bleaching liquid and promoter, change the molecular structure and the palatability of fiber again with the method for extrusion, make it to take for people easily.
The invention has the beneficial effects as follows, the short easy operating of this technological process, the production equipment of demand is simple and easy to, particularly change the molecular structure and the palatability of fiber with the method for extrusion, make it to take for people easily, for the deep processing of sweet potato granulated slag provides a kind of feasible approach, the dietary fiber of being produced can directly be taken, and also can cooperate with other raw materials and produce the health food that is rich in dietary fiber.
