Curdlan (Curdlan) is the high molecular polymer as caused by specified microorganisms fermentation saccharine material, is a kind of
Safe and healthy natural polysaecharides foodstuff glue, insoluble in cold water, is dissolved in alkali, can form reversible glue and irreversible glue, be often used as
Food quality modifying agent, the viscoplasticity, stability and toughness of food can be improved, can also a kind of dietary fiber work low in calories
For functional food ingredient.The irreversible glue function that curdlan is formed is unique, and economic value is big, is not dissolved in yet with it
Water, function can not give full play to, and not easy to operate, limit its application in food.Technology provided by the invention can
Curdlan intramolecular hydrogen bond is destroyed so as to improve its solubility property in water by pre-gelatinized, simplifies operation, raising can obtain
The utilization rate of right glue.
The content of the invention
The present invention relates to a kind of correlation technique for improving curdlan solubility property.
The technical scheme that the present invention solves used in its technical problem is to handle to obtain by pre-gelatinized to be easy to obtaining for dissolving
Right glue, comprises the following steps：
Curdlan is added in size-mixing tank, the waterside that side adds Jing Guo purification process is stirred, and 5-10 weights are made
Measure % curdlan dispersion liquid；0.1 weight % chemical addition agent is added in curdlan dispersion liquid, continues 10 points of stirring
Clock, it is re-fed into pre-gelatinized machine and carries out pre-gelatinized, drying process, obtain transparent thin skin into strips, pre-gelatinized is obtained by crushing
Curdlan.
In the method described in the present invention, the curdlan is the curdlan that effective content is 80-99 weight %.
In the method described in the present invention, the water by purification process is one kind in deionized water, distilled water.
In the method described in the present invention, the chemical addition agent is sodium carbonate, sodium hydroxide, potassium hydroxide, tricresyl phosphate
One or more in sodium, calcium hydroxide.
In the method described in the present invention, the pre-gelatinized machine is twin-roll pre-gelatinized machine.
In the method described in the present invention, steam pressure used in the pre-gelatinized processing is (7-8) X105Pa。
In the method described in the present invention, the drum surface temperature of the pre-gelatinized machine is 110-130 DEG C.
In the method described in the present invention, the rotating speed of the pre-gelatinized machine cylinder is 1000r/min.
The present invention obtains pre-gelatinized curdlan according to above-mentioned preparation method, can effectively improve the dissolubility of curdlan
Can, simplify curdlan application method, improve curdlan utilization rate.
The present invention is described more fully below.
In the present invention, it is preferred to curdlan uses product (MC of the purity that in the market is bought for 86 weight %
Food Specialties Inc., Japan), it is made into 5-10 weight % curdlan dispersion liquid；In curdlan dispersion liquid
0.1 weight % of middle addition chemical addition agent, continue stirring 10 minutes, be re-fed into pre-gelatinized machine and carry out pre-gelatinized, drying process,
Steam pressure used is (7-8) X10 in this step5Pa, the drum surface temperature of pre-gelatinized machine used is 110-130 DEG C, so
Transparent thin skin into strips is obtained afterwards, and pre-gelatinized curdlan is obtained by crushing.
