The starch can be used for industrial fermentation and also can be used for manufacturing resistant starch and modified starch, such as dextrin and the like. According to the comprehensive utilization method of a Canna edulis Ker tuber, the high-valued utilization and the comprehensive utilization of the Canna edulis Ker tuber can be realized, and the comprehensive utilization method has economic value and is a new environment-friendly energy-saving technology.
Description
Technical field
The present invention designs a kind of food technology field.A kind of bajiao banana taro stem tuber comprehensive utilization processing technology that is raw material production starch, food fibre specifically.
Background technology
The bajiao banana taro, formal name used at school any of several broadleaf plants lotus root (Canna edulis Ker) belongs to the non-irrigated lotus root of Cannaceae (Cannaeeae), any of several broadleaf plants lotus root, achira, per nnial herb, originate in the ground such as South America, have wide adaptability, happiness Wen Guang, strong stress resistance, high, the easily cultivation of output, the characteristics such as purposes is wide are suitable for the growth of high temperature and rainy area, do not select soil.
The production potential of bajiao banana taro are very large, and its stem tuber output can reach 4000-5000kg/ mu in the Southwestern China province, are the new raw material sources that become high value starch at present, also are the good raw materials of brewageing fermentation, food and feed processing.In addition, a large amount of bajiao banana taro stem stalks of results are a kind of important biomass resource equally in the results stem tuber.
The economic worth of bajiao banana taro is mainly reflected in the utilization of stem tuber at present.Because bajiao banana taro stem tuber contains much starch, the main application of therefore present bajiao banana taro is the raw material as Starch Production.Have report to show, canna starch has that granularity is large, solubleness is high, the strong and advantage such as clarity is high, freeze-thaw stability is good with the water binding ability.But, because the method labour intensity of conventional pulverizing washing is large, efficient is low, needs the new technology of exploitation to be improved, to improve the efficient of Starch Production.
The problem that another of canna starch production need to solve is the problem of complex utilization of raw material.When starch is extracted, produce a large amount of waste residues, be difficult to process.The waste of raw material is not only in the generation of these waste residues, has also caused environmental pollution.Therefore, need exploitation stem tuber can be carried out the new technology of ecology comprehensive utilization simultaneously in the starch utilization.Although there has been the scholar to notice this problem, and developed a series of utilize the bajiao banana taro to extract starch after remaining residue produce the polysaccharide polyphenol complex (preparation method of canna edulis ker polysaccharide polyphenol complex, application number 200910054318.7), the soluble dietary fibre (preparation method of canna edulis ker soluble dietary fiber, application number 200910312509.9) with as the report of wrapping paper raw material (utilizing any of several broadleaf plants lotus root slag to make the production technique of wrapping paper, application number 03157623.0).But because the cellulosic material compact structure, carry out trans-utilization under the pretreated prerequisite and often exist utilization ratio low, the problem that product is difficult to extract raw material (canna slag) not being done.
Steam explosion is the preprocessing method of raw materials of low-energy-consumption high-efficiency in a kind of lignocellulose utilization.Field outside lignocellulose also is applied more and more in recent years.High-temperature steam and moment quick bursting effect not only can make the part macromolecules degradation, can destroy simultaneously the structure of raw material densification, be that wherein composition is easier to be separated and utilize.This method is applied in the crushing process that not only can replace extracting the starch use in the utilization of bajiao banana taro stem tuber and can also so that the fibre composition in the stem tuber becomes loose, makes things convenient for the preparation of food fibre.In addition, can also improve the quality of food fibre by explosion treatment.
For the problems referred to above and solution thinking, we have developed the bajiao banana taro stem tuber comprehensive utilization novel process take the steam explosion pre-treatment as core.
Summary of the invention
A kind of technology that fully utilizes bajiao banana taro stem tuber that the object of the invention is to take full advantage of bajiao banana taro stem tuber and develop.Raw material of the present invention is concentrated, output is large, cheap, it is convenient to collect, and comprehensive utilization has realized the biomass complete utilization, and starch recoveries is high, is a kind of eco-friendly eco-utilization technology therefore.
The present invention is with the comprehensive utilization of following technological line realization bajiao banana taro stem tuber, and its technological process is as follows:
Step 1: bajiao banana taro stem tuber is carried out steam explosion process;
Step 2: the stem tuber after water flushing steam explosion is processed, then leave standstill washings, be settled out starch.
Step 3: remaining waste residue after pulverising step two is processed, mix, then use successively amylase, cellulase, pancreatin to process with tap water according to 1:10 ~ 1:20, add at last ethanol and be settled out food fibre.
The condition of above-mentioned steps one steam explosion is that 0.6 ~ 1.0MPa held time 2 ~ 6 minutes.
The present invention has following characteristics:
1) use steam explosion processing raw material before extracting starch, so that the structure deteriorate of raw material, starch exposes, and conveniently further extracts, and is lower with pulverizing phase specific energy consumption simultaneously.The quick-fried processing of vapour is so that cellulose crystallity descends easier being utilized in addition.
2) realized the complete utilization of bajiao banana taro stem tuber.The before utilization for bajiao banana taro stem tuber focuses mostly in the utilization to starch, does not so not only fully develop bajiao banana taro resource, and produced simultaneously waste residue has also brought more serious pollution problem.Set up bajiao banana taro stem tuber comprehensive utilization technique take steam explosion as core and realized the complete utilization of stem tuber, not only have economic benefit, have preferably ecological benefits.
