Description

A kind of potato slag based on potato juice, potato juice, the comprehensive utilization of modified starch Method
Technical field
The invention belongs to potato industrial processing technology field, be related to a kind of potato slag based on potato juice, potato juice, The method of comprehensive utilization of modified starch.
Background technology
With the proposition of China's potato staple food grainization strategy, potato is by as the 4th after rice, wheat, corn Big staple food grain crop.High-moisture turns into the bottleneck of potato staple food grain, and potato class belongs to food transboundary, has grain, vegetables and fruit concurrently Feature, nutritional ingredient is abundanter than cereal, comprehensively, trophic structure also more beneficial human health.But why pass through 1,100 Evolve, screen, wheat, rice, corn can turn into mankind's staple food grain, and, nutrition more stronger than cereal crops growth adaptation ability is more Abundant potato but can not.Main reason is that tuber crops stem tuber water content is high, perishable, storage is difficult.Natural conditions Under, can storage be conveniently that ancient times mankind selection staple food grain needs the matter of utmost importance of consideration.Cereal crops water content is few, only needs simple Drying can just be stored for a long time, and human maximum degree can be allowed to avoid famine, naturally as mankind's staple food grain, and this is based on society The inevitable choice of productivity dynamics level.
Potato is natural intolerant to accumulating, and natural form cannot be used as staple market circulation grain.At present in the big portion of China Region-by-region, potato is all or edible mainly as vegetables.And potato staple food grain is promoted, it is not intended to allow owner to take daily Potato eats when meal, it is important to food processing industry of the development using potato as raw material.
Industrialization processing is the only way of Potato Industry staple food grainization development, processing of farm products institute of the Chinese Academy of Agricultural Sciences chief Dai little Feng once explained potato staple food grain in popular mode, was exactly that staple food grain does not allow for everybody that potato is directly treated as staple food Eat, but potato is become suitable for making by industrializing processing the product of the staple foods such as steamed bun, noodles, ground rice, realize Ma Ling Potato consumes the transformation consumed to staple food from non-staple foodstuff.Staple food grain intension is exactly by non-staple foodstuff change staple food, by family or workshop potato Formula production and processing becomes factorial praluction, makes it easily to combine with rice, face etc., can also individually eat, become in meeting The boiling type novel product of state's Traditional consumption habits.
On the road of dehydrated potato powder staple food grain, it is one of current selection that potato is processed into powder.With fresh Ma Ling Potato is raw material, cleaned, remove the peel, select, cutting into slices, rinsing, precooking, cooling down, boiling, the technical process such as mud being smash, through dehydrating Obtained by graininess, piece bits shape or powdery product be referred to as potato full-powder.Because potato full-powder is free of mucedin, When making the staple food grain products such as steamed bun, noodles, there are problems that shaping is difficult, treacle is raised difficult questions, hardness, there is technology all the time for many years Obstacle.In addition, potato is to be rich in carbohydrate food, content of starch is high, and its contained resistant starch (RS2) heat is extremely unstable It is fixed, directly it is cooked to eat and easily digests and assimilates, and also the longer glycemic index of digestion time (GI) is higher.Full powder is potato It is made after boiling, it is 73 that mashed potatoes GI is made by raw material of full powder, and chips are 60, compared with cereal master for control postprandial blood sugar Grain is without significant advantage.And powder process energy consumption is higher entirely, typically constitutes from totle drilling cost 60-70%.For example:Process 5 tons of potatos 1 ton of potato full-powder finished product is obtained, it is front and rear to need to remove 4 tons of water and disintegrating slag.1 ton of complete 10,000 yuan or so of powder price, the full powder valency of purple potato Lattice are more than 30,000 yuan, and only 3000 yuan of one ton of long patent flour price.
A kind of staple food vermicelli for being called mealy potato that many people have on the market, its raw material is finished potato in fact Starch, in process, it is only extracted in potato 17% or so starch component, adds other raw materials individually to add Work, and remaining nutritional ingredient is then dropped entirely.At present, there are family more than 100, small-sized enterprise in domestic larger farina enterprise The over thousands of family of industry, there are into China, the Great Northern Wilderness, Nai Lun, magnificent Europe etc. in the enterprise of scale wherein in production capacity.
It is a global problem to extract the potato slag after starch, the processing of potato juice for farina enterprise.Potato carries Take after starch, potato slag aqueous 80% or so is not possessed liquid fluidity, presented with colloid property, containing accounting for butt proportion 37% The nutriment such as starch, 31% cellulose, 17% pectin, 4% protein/amino acid;Potato juice aqueous 95% or so, Starch-containing 0.5%, albumen 1.2%, rich in a large amount of dietary fibers, vitamin, trace element, electrolyte etc., further exploitation is sharp It is high with being worth.Due to currently lacking corresponding treating method, farina enterprise generally cooks potato slag, potato juice at discarded object Reason, stops production so that environmental protection is not up to standard.Such processing is obviously unreasonable, not only causes very big waste, and potato slag, potato juice After corruption, the problem of meeting generation environment pollutes again causes very big pressure to enterprise and environment.
