Description
[technical field]
The invention belongs to the raw-food material manufacture field, the full biomass method of comprehensive utilization of particularly a kind of konjaku.
[background technology]
Konjaku is unique plant that contains Glucomannan in a large number of finding on the earth so far.China has abundant and the konjaku resource of high-quality, the record of cultivating konjak is promptly arranged before surplus 1700 year, but up to phase early 1980s, its research and utilization is almost blank.But subsequently more than 20 year, earth-shaking variation has taken place in the konjaku industry of China.Nowadays China's konjaku is by a little vegetable crop that runs its course; Develop into one of fist industrial crops that present southern hill farmer gets rich; Product is also by originally single black konjak tofu over one hundred kind of food up till now; Also be widely used in the industries such as medicine, chemical industry, oil, weaving, konjaku has formed an emerging rising industry at present.
Konjaku is the local product resource of China, and China has more than 20 kind approximately, and it mainly is distributed in the ground such as Hubei, Hunan, Sichuan, Yunnan, Guizhou, Jiangxi, Anhui, Guangxi and Taiwan on the south the Yangtze river basin.Konjaku is important industrial crops, and raw material production has the output height, the tangible characteristics of benefit.About 430,000 mu of the cultivated area of China's konjaku, about 200,000 tons of bright taro annual production.According to one's analysis; The konjaku stem tuber is starch-containing 1.46%, protein 2.56%, fat 0.13%, glucomannans 64.78%, reduced sugar 11.61%, cellulose 11.43%, ash content 3.76%, moisture 17.76%, also contains multivitamin and alkaloid 1%～2%.
China only payes attention to the benefit that the konjaku powder outlet brings at present, and on the deep development of konjaku product, still very is short of.When konjaku is processed into smart powder, also can produce accessory substances such as fry starch of konjak in fact.With regard to the domestic konjaku powder dry method that generally adopts; Add trade union and produce leftover bits and pieces such as 10%～20% skin, waste residue; Wherein the konjaku skin accounts for major part, because these leftover bits and pieces have pungent acid, to the growth of plant, grow and have stronger inhibition and injury effect; Therefore, at present all with it as garbage disposal.In the konjaku powder process, also can produce powder in light weight, that particle is little, be called fry starch of konjak, account for 30%～40% of smart powder, reach about 5000t according to the smart powder annual production of China and calculate, the whole nation is produced per year and is flown powder 1500～2000t.And fry starch of konjak contains protein about 20%, and starch about 40% also contains alkaloid, Flavonoid substances, polypeptide, ceramide isoreactivity material.Wherein alkaloid has obvious suppression, avoids and keep away and toxic action many insects and mushroom, thereby can produce the emulsifying agent and the synergist of nuisanceless mulch film and agricultural chemicals; In addition, konjaku can divide multiple materials such as managing out betulinic acid, cupreol, melissane, wood sugar and carrotene, ascorbic acid through processing.But fry starch of konjak is sold with the low price feed or as drier mostly at present, and value is extremely low.The added value that therefore, improve konjaku must be explored new utilization of resources approach.
[summary of the invention]
[goal of the invention]
Low to present konjaku resource utilization degree; The problem that lacks the effective means of the full biomass utilization of clean and effective; The present invention provides a kind of konjaku comprehensive utilization method, realizes that the konjaku skin extracts the Poly-generation ecological industry exploitation of alkaloid, konjaku stem tuber wet grinding powder process, fry starch of konjak extraction ceramide, grinding waste liquid fermentation methane and ethanol, both can improve the konjaku resource utilization; Reduce environmental pollution, and realized the full biomass utilization of konjaku.
[inventive concept]
Be substantially free of glucomannans in the konjaku skin, and alkaloid is higher, normally is used as rubbish to abandon, soil is produced harmful effect; Glucomannans content is greater than 60% in the konjaku stem tuber; Next cellulose, reduced sugar, protein, starch, fat etc.; The accessory substance that powder process produces mainly is wet grinding waste liquid, fry starch of konjak etc.; Wherein mainly be undrawn glucomannans, ethanol, starch, cellulose and reduced sugar etc. in the wet grinding waste liquid, remaining liquid is the good raw material of fermentation methane behind the recovery ethanol; The fry starch of konjak stock number is big; Can account for 30%～40% of smart powder; And the content of ceramide is 10 times (like rice bran, rice plumule and wheat bran etc., only containing 0.01%～0.02% ceramide) of ceramide raw material commonly used up to 0.15%～0.2% in the konjaku; Be used for extracting the cost that ceramide not only can reduce ceramide; And the high value added utilization of realization fry starch of konjak, the waste liquid behind the extraction ceramide can reclaim ethanol equally, and the waste liquid behind the recovery ethanol also can be used for fermentation methane.Just the full biomass clean and effective that can realize rivieri raw material through above-mentioned approach transforms.
[technical scheme of the present invention]
A kind of konjaku comprehensive utilization method of the present invention is characterized in that may further comprise the steps:
1) raw material pre-treatment: fresh Amorphophallus rivieri cleaned dry surface moisture, remove impurity such as epidermis worm scar and terminal bud, peeling, and stripping and slicing;
2) konjaku skin alkaloid extracts: adopt Ethanol Method to extract the alkaloid in the konjaku skin, extract the back waste liquid and reclaim ethanol, the wet grinding waste liquid behind waste residue and the recovery ethanol mixes, and is used for biogas fermentation;
3) the konjaku piece protects look: carry out preimpregnation 3s according to protecting the look aqueous solution with rivieri raw material weight ratio adding in 1: 0.5～1: 2;
4) konjaku vapour is quick-fried: the rivieri raw material after the pre-preg is placed steam-explosion jar, and setting vapour detonation pressure power is 0.5～2.0MPa, and the dimension pressure time is 10s～5min; Abrupt release pressure promptly obtains the quick-fried rivieri raw material of vapour then;
5) the quick-fried konjaku wet grinding of vapour prepares konjaku flour: after the quick-fried konjaku of vapour is regulated moisture, add directly that protective agent carries out wet grinding, the quick-fried konjac meal of vapour after will pulverizing is crossed 100 eye mesh screens, remove anhydrate, behind starch and the impurity, the dry konjac meal for preparing;
6) wet grinding waste liquid comprehensive utilization: mainly be ethanol, starch, sugar and cellulose in the wet grinding waste liquid; Reclaim the ethanol in the lapping liquid; In the remaining lapping liquid mainly is starch, sugar and cellulose and step 2) in the konjaku skin waste residue that reclaims behind the ethanol merge, be used for biogas fermentation;
7) fry starch of konjak comprehensive utilization: alcohol extract fry starch of konjak high value added product ceramide, fly the extract recovery ethanol after powder extracts ceramide, be rich in starch, protein and polysaccharide in the residue extract and be used for biogas fermentation;
8) ethanol reuse: step 2), 6) and 7) in the ethanol that reclaims can be used as konjaku powder and grind protective agent.
A kind of konjaku comprehensive utilization method of the present invention is characterized in that the alkaloid extracting technique condition is in the described konjaku skin: concentration of alcohol 75%, the feed liquid w/v of konjaku skin and ethanol is 1: 15, extracts 45 ℃ of temperature, extraction time 1.5h.
