Abstract
The present invention relates to a method for eliminating alkaloid and abnormal smell in konjaku powder. The extrusion cooking technology is utilized to treat konjaku powder to degrade alkaloid in the konjaku powder and eliminate abnormal smell brought by trimethylamine; the alkaloid and the abnormal smell in the konjaku powder are eliminated after the konjaku powder is treated. Therefore, the konjaku powder can be widely used for the food processing field, the bonding field, the fermenting field, the field of producing various kinds of feed, etc. Thereby, the value of commodity is improved greatly. Simultaneously, the method has the characteristics of simplicity, easy operation, no pollution, low cost, etc.
Description
Technical field
The present invention relates to the agricultural byproducts processing field, particularly relate to a kind of method of eliminating alkaloid and peculiar smell in the fry starch of konjak.
Background technology
Konjaku (Amorphophallus konjac) is Araeceae (Araceae) Amorphophallus (Amorphophallus blume) herbaceos perennial, You Cheng Amorphophalus rivieri.Mainly be distributed in mountain area, China southwest, bulb contains abundant konjak glucomannan, starch, protein, mineral matter and alkaloid etc., its application history of existing near bimillennium, and middle " Amorphophalus rivieri root on the books early rubbed and passed the carbuncle pyogenic infections Song dynasty " Katyuan book on Chinese herbal medicine ", and is effective." find out that thus Ancient Times in China is mainly used in edible and the compatibility aspect of being used as medicine to konjaku.The plantation of development konjaku and deep processing have very big meaning to poverty alleviation, environmental protection, the development of quickening central and west regions.But because konjaku is lacked degree of depth technological development, rest on for a long time on the level of agricultural planting and processing primary product, its bigger economic worth fails to excavate.To the development of konjaku, the task of top priority is to strengthen the scientific research and development dynamics, makes the potential economic worth of konjaku change the economic benefit of reality as early as possible into.In recent years, especially recent two decades comes, and along with development of modern science and technology, people have more deeply recognized the potential value of konjaku resource, and the application of konjaku is extended to industrial various fields from simply being used as medicine and eating, has carried out omnibearing comprehensive development and utilization.
Be processed in the process of industrial required konjaku powder at konjaku, produce simultaneously almost with smart powder and fly powder (konjak glucomannan particle surface attached component and konjaku epidermis composition in the konjaku processing under the grinding) with amount (account for system powder 36%-45%, all the other be smart powder).Fly to contain in the powder trimethylamine of irritating alkaloid of 0.25%-0.60% and strong peculiar smell, make its commodity value very low, be used as the animal feed of low value mostly, market price only is 400～600 yuan/ton.Though people have adopted several different methods, remove wherein alkaloid, eliminate peculiar smell as organic solvent lixiviate, pickling, effect is unsatisfactory, and cost is very high.
Summary of the invention
The object of the present invention is to provide a kind of method of eliminating alkaloid and peculiar smell in the fry starch of konjak, this method adopts extrusion cooking, by processing to fry starch of konjak, and wherein the alkaloid of degrading, and the peculiar smell that brings of elimination trimethylamine.
This method realizes successively through the following steps:
1, after fry starch of konjak adds the water stirring, left standstill under the room temperature 20～30 minutes, controlling its moisture is 16%～20%;
2, with comminutor above-mentioned material is made the particle that granularity is φ (2～3) * (4～a 5) millimeter;
3, above-mentioned particle is carried out extrusion cooking with the twin-screw extrusion cooking machine, temperature is 125～150 ℃;
4, with leaving standstill 3～5 minutes after the extruded material cut-out, pulverize with pulverizer, granularity is 40～60 orders, is the fry starch of konjak that removes alkaloid and peculiar smell.
In the said method, the particle of φ (2～3) * (4～5) millimeter, the diameter of (2～3) expression particle, the length of (4～5) expression particle.
The invention has the advantages that the fry starch of konjak after the processing owing to eliminated alkaloid and peculiar smell in the fry starch of konjak, makes fry starch of konjak can be widely used in fields such as food processing, bonding, fermentation, all feeds production, the big raising of commodity value.Simultaneously, this method has characteristics such as simple, easy to operate, pollution-free, that cost is low.
The specific embodiment
Embodiment 1:
Get 500 kilograms of fry starch of konjak, add water and stir, left standstill under the room temperature 20 minutes, with comminutor the gained material is made the particle that granularity is 2 * 4 millimeters of φ, carry out extrusion cooking with the twin-screw extrusion cooking machine, temperature is 125 ℃; With leaving standstill 3 minutes after the extrudate cut-out, to pulverize with pulverizer, granularity is 40 orders, is the fry starch of konjak that removes alkaloid and peculiar smell.
Embodiment 2:
Get 1000 kilograms of fry starch of konjak, add water and stir, left standstill under the room temperature 25 minutes, with comminutor the gained material is made the particle that granularity is 2 * 5 millimeters of φ, carry out extrusion cooking with the twin-screw extrusion cooking machine, temperature is 140 ℃; With leaving standstill 4 minutes after the extrudate cut-out, to pulverize with pulverizer, granularity is 50 orders, is the fry starch of konjak that removes alkaloid and peculiar smell.
Embodiment 3:
Get 2000 kilograms of fry starch of konjak, add water and stir, left standstill under the room temperature 30 minutes, with comminutor the gained material is made the particle that granularity is 3 * 4 millimeters of φ, carry out extrusion cooking with the twin-screw extrusion cooking machine, temperature is 150 ℃; With leaving standstill 5 minutes after the extrudate cut-out, to pulverize with pulverizer, granularity is 60 orders, is the fry starch of konjak that removes alkaloid and peculiar smell.
Claims (1)
1, a kind of method of eliminating alkaloid and peculiar smell in the fry starch of konjak is characterized in that comprising the following steps: successively
(1) after fry starch of konjak adds the water stirring, left standstill under the room temperature 20～30 minutes, controlling its moisture is 16%～20%;
(2) with comminutor above-mentioned material is made the particle that granularity is φ (2～3) * (4～a 5) millimeter;
(3) above-mentioned particle is carried out extrusion cooking with the twin-screw extrusion cooking machine, temperature is 125～150 ℃;
