The invention provides a method for extracting mucuna starch. The method for extracting the mucuna starch includes adding lime water with a material-liquid ratio of 1:3-7 into mucuna powder and extracting the mucuna powder for 1-2 h to obtain sediments; washing the sediments by the aid of water; sieving the sediments by 16-mesh screen cloth; centrifuging the sediments; carrying out previous steps again once; drying the sediments to obtain the mucuna starch. The method for extracting the mucuna starch has the advantages that the method is easy to implement, short in extraction cycle, high in efficiency, low in cost and suitable for extracting the mucuna starch on a large scale, and the mucuna starch is high in extraction content and purity.
Description
Technical field
The present invention relates to extraction process technology field, particularly relate to a kind of method extracting Semen stizolobii capitati starch.
Background technology
Semen stizolobii capitati has another name called cat bean, Semen Stizolobii Cochinchinensis, white Semen stizolobii capitati, Canis familiaris L. bean, is the seed of pulse family Mucuna plant, for Guangxi characteristic medicine-food two-purpose resource plant.Its original producton location is South Asia, at Southwestern China, also has distribution south China height above sea level 800 ~ 1400m tor, and Guangxi is topmost producing region.Containing natural levodopa in cat bean, there is important using value, in addition, possibly together with substantial amounts of protein and starch.In China, Semen stizolobii capitati is processed into roughage by only indivedual producers, or utilizes its partial starch to be processed into vermicelli, and remainder is abandoned in vain, causes waste and pollutes environment.
In Semen stizolobii capitati, content of starch is the abundantest, suitable with Food Legume, has higher using value.The wild Semen stizolobii capitati of development and utilization, can improve the economic benefit of flour mill, make rational use of resources, and promotes oil and foodstuffs industrial expansion.But the at present exploitation to Semen stizolobii capitati are concentrated mainly on the extraction of the materials such as levodopa in Semen stizolobii capitati and utilize aspect, the most not about the research of Semen stizolobii capitati starch isolation technique.
Therefore, prior art needs to improve further.
Summary of the invention
In view of the deficiencies in the prior art, the invention reside in a kind of method extracting Semen stizolobii capitati starch of offer, it is intended to solve currently without effective Semen stizolobii capitati starch isolation technique.
Technical scheme is as follows:
A kind of method extracting Semen stizolobii capitati starch, wherein, described method is:
Adding in Semen stizolobii capitati powder in the lime water that solid-liquid ratio is 1:3-7 and carry out extracting 1-2h, washed by precipitate, after 16 eye mesh screens, be centrifuged precipitate, repeat the above steps once, dry by the precipitate obtained, and obtains Semen stizolobii capitati starch.
The described method extracting Semen stizolobii capitati starch, wherein, the mass percent concentration of lime water used is 0.1%-1%.
The described method extracting Semen stizolobii capitati starch, wherein, the mass percent concentration of lime water used is 0.3%.
The described method extracting Semen stizolobii capitati starch, wherein, the temperature conditions of extraction used is 40-50oC。。
The described method extracting Semen stizolobii capitati starch, wherein, described in sieve after the solid-liquid ratio of raw material and lime water be 1: 5.
The described method extracting Semen stizolobii capitati starch, wherein, described extraction time is 1.5h.
The described method extracting Semen stizolobii capitati starch, wherein, by the Semen stizolobii capitati starch obtained be deposited in 40-45 DEG C at be vacuum dried.
Beneficial effect: the present invention provides a kind of method extracting Semen stizolobii capitati starch, and described extracting method is simple to operate, the extracted amount of Semen stizolobii capitati starch is high and purity is high, and extracting cycle is short, and efficiency is high, and with low cost, is suitable for carrying out the extensive extraction of Semen stizolobii capitati starch.
Detailed description of the invention
The present invention provides a kind of method extracting Semen stizolobii capitati starch, and for making the purpose of the present invention, technical scheme and effect clearer, clear and definite, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention provides a kind of method extracting Semen stizolobii capitati starch, and described method is:
Adding in Semen stizolobii capitati powder in the lime water that solid-liquid ratio is 1:3-7 and carry out extracting 1-2h, washed by precipitate, after 16 eye mesh screens, be centrifuged precipitate, repeat the above steps once, dry by the precipitate obtained, and obtains Semen stizolobii capitati starch.
Owing to Semen stizolobii capitati starch dissolubility in alkali liquor is low, easily separate out with the form of precipitation, and the alkalescence of lime water is strong, and with low cost, it is suitable for extracting Semen stizolobii capitati starch.Owing to along with the increase of lime water concentration, starch extraction rate declines.This it may be the case that alkalescence lime water concentration increase time, have impact on the structure of starch, thus have impact on its dissolubility in extracting solution.When the mass percent concentration of lime water used is 0.1%-1%, and Semen stizolobii capitati starch dissolubility in the lime water of this concentration range is the lowest, extracted amount is high, and the starch extracted not changeableness.Preferably, when the mass percent concentration of lime water is 0.3%, the extraction efficiency of Semen stizolobii capitati starch is the highest, and quality is best.
The described method extracting Semen stizolobii capitati starch, wherein, the temperature conditions of extraction used is 40-50oC。。
Along with the addition of lime water increases, starch extraction rate raises, but when lime water is too much, the physicochemical property of starch changes, and dissolubility improves on the contrary, and starch extraction rate reduces.When solid-liquid ratio is 1:3-7, can guarantee that starch has higher extraction ratio.Preferably, when after sieving, the solid-liquid ratio of raw material and lime water is 1: 5, starch extraction rate is the highest.
Owing at short notice, along with the prolongation starch extraction rate of soak time increases, but during long soaking time, the structure of starch changes, and starch extraction rate declines, and starch quality declines.When described extraction time is 1-2h, starch isolation amount is high.Preferably, when described extraction time is 1.5h, starch isolation amount is the highest, little on starch quality impact.
Precipitate extraction obtained is washed, after 16 eye mesh screens, can the farthest impurity in sediment separate out, without to the extracted amount reducing starch.Subsequently the precipitate crossing screen cloth is centrifuged.
Wherein, by the Semen stizolobii capitati starch obtained be deposited in 40-45 DEG C at be vacuum dried.
The Semen stizolobii capitati starch quality that the present invention extracts is good, and purity is high, has multiple use.Wherein it is possible to be used for making appetizing cake or wheaten food, not only greatly limit utilizes the value of Semen stizolobii capitati, and meets the requirement of modern's height quality of life, and promotes the development of cake industry, produces huge economic benefit.
For the preparation method of the more detailed description present invention, it is exemplified below several embodiment further description.
