Abstract

The invention provides a method for separating Tara bean gum from Tara beans. The method is characterized by comprising the following processing steps of: (A) heating Tara beans to 95-145 DEG C; (B) sending the Tara beans heated in the step (A) onto a roll extruder to be extruded until the Tara beans are broken; and sieving the broken Tara beans and then cooling the broken Tara beans to room temperature to obtain the Tara bean gum. The Tara bean gum can be peeled off bean shell walls, and the gum yield reaches more than 80 percent. Moreover, the shape of the separated Tara bean gum can still be maintained complete without cracks, Tara polysaccharide in the bean gum maintains consistent with a natural state in the aspects of colors, fragrance, shapes and taste, and the Tara bean gum has better bioactivity. The problems of low gum peeling efficiency, large broken gum quantity, difficult quality guarantee, and the like of the Tara beans are solved so as to effectively improve the utilization value of Tara bean products. The invention has simple process, convenient operation, less investment, no area occupation and easy scale and automatic production.

Description

Draw from tower and to isolate the method that tower draws bean gum the beans

Technical field

The present invention relates to a kind of separation method of bean gum, especially draw the method for obtaining bean gum the beans, belong to technical field of agricultural product process from tower comparatively hard and the tool multilayered structure.

Background technology

It is a kind of economic plants of preciousness that tower draws tree Caesalpinia spinosa Kuntze, belong to Caesalpiniaceae (Caesalpiniaceae) Caesalpiniaceae, a kind of dry heat resistance, impoverishment tolerant, fast tool living, that the four seasons are evergreen that mysorethorn belongs among the Caesalpinia sting shrub or dungarunga.Its country of origin is a Peru, mainly is distributed in South America.The beanpod that tower draws tree to bear draws beanpod shell and Ta La beans to form by tower, wherein tower draws beans to be made up of beans shell, bean gum, cotyledon and four kinds of materials of plumule again, it is that tower draws polysaccharide that tower wherein draws the main component of bean gum, be widely used in the industries such as food, healthcare products, drink, medicine, weaving, papermaking, petroleum drilling, in food, healthcare products, drink, medicine and other fields, tower draws bean gum mainly as thickening material, stablizer, emulsifying agent, tackiness agent, properties-correcting agent and be employed.

Because tower draws the beans shell very hard, tower draws bean gum to be close to hard beans shell inwall again, is difficult to its monoblock is peeled off.At present external lift-off technology is that bean gum and beans shell, cotyledon, embryo are together gone to pieces, in case and these fragments mix mutually, not only very difficult bean gum is separated, but also can influence the quality that tower draws bean gum.At home, owing to there is not this processing technology, tower draws beans can only be used for breeding, cultivates seedling, and therefore, the mechanically peel technology that the exploitation tower draws bean gum fundamentally to solve the separation processing problems that tower draws bean gum, is met the need of market, and has become important topic now.

Summary of the invention

Draw bean gum to separate difficult problem for overcoming present tower, the invention provides the separation method that a kind of tower draws bean gum, to satisfy market demand.

The present invention realizes by following technical proposal: a kind ofly draw the method that knockout tower draws bean gum the beans from tower, it is characterized in that through following process steps:

A, Jiang Ta draw beans to be heated to 95～145 ℃;

B, the tower that the A step is heated draw beans to send on the pair roller extrusion machine, are squeezed to tower and draw the beans fragmentation, sieve postcooling to room temperature, i.e. the De Tala bean gum.

Described A step tower is drawn beans when heating, be heated to 95～145 ℃ after, be incubated 2～5 minutes, make attached to tower and draw the bean gum of beans shell inwall to be heated and soften.

Described B step draw beans with pair roller extrusion machine crush tower the time, the control clearance between roll is 0.9～2.9mm, linear differential is 5～20mm between roller, concrete clearance between roll draws the beans size decide on tower, the linear differential value is looked tower and is drawn the beans size concrete definite between roller.

The extruding number of times of described B step is for once or repeatedly, and concrete number of times draws bean gum and beans shell to break away from fully on tower to decide.

The pair roller extrusion machine of described B step is a conventional equipment of the prior art.

The technological difficulties that the present invention will solve are: draw in the course of processing of beans at tower, by specified temp and machinery control, the material of four kinds of different structure layers is squeezed simultaneously and stranding is driven away, because tower becomes software after drawing bean gum to be heated, therefore drive away in the process in extruding and stranding, have only tower to draw the bean gum shape that is kept perfectly, not brokenly do not split, it is broken that other three kinds of materials then are extruded stranding, thereby draw bean gum to peel off out from beans shell inwall in tower, finishes the separation that tower draws bean gum.

The present invention compared with prior art has following advantage and effect: adopt above-mentioned simple technical scheme, not only tower can be drawn bean gum peel off out from the beans shell wall, rate of gum output reaches more than 80%, and the tower of separating draws the bean gum shape still can be kept perfectly, not brokenly do not split, and make the tower in the bean gum draw polysaccharide at look, fragrant, shape, all be consistent on the flavor with native state, make it to have preferable biological activity, it is low fundamentally to have solved prior art Yin Tala beans stripping glue rate, broken glue amount is big, quality is difficult to problems such as assurance, thereby has effectively improved the utility value that tower draws the beans product.In addition, technology of the present invention is simple, and is easy to operate, and less investment is not taken up an area of, and is easy to mass-producing, automatic production, is that an ideal obtains the processing method that the high yield and high quality tower draws bean gum in fact.
