Abstract
The invention relates to a preparing method for fast dissolving agar that includes the following steps: dispersing the agar and flux into water under the condition of whisking, boiling for several minutes until fully dissolved; freezing the agar sol until fully frozen, then thawing; dehydrating; drying in natural or by hot air, and spraying the flux on to the surface of dried material; smashing and filtering to gain fast dissolving agar. The invention could be widely used in food, medicine, chemical fields.
Description
Technical field
What the present invention relates to is the method in a kind of food engineering field, specifically is a kind of preparation method of quickly dissolving agar.
Technical background
Agar is a kind of natural macromolecule amylose material that refining is purified from marine algas such as natural stone cauliflower, fragrant plant mentioned in ancient texts dish (Gracilaria), laver, classified as generally regarded as safe product by U.S. food medication management regulations, get permission to be written among the food chemistry product pharmacopeia as special topic as foodstuff additive.Agar is lyophilic colloid, is insoluble to cold water, is soluble in hot water.Agar has unique importance industrial, even the concentration of agar is low to moderate 1% gel (frozen glue) that still can form quite stable, is foodstuffs industry, chemical industry, the essential raw material of medical research institute.
Find by prior art documents, Chinese patent publication number 1587284, open day is on March 2nd, 2005, denomination of invention is: the production method of agar is produced in a kind of high temperature ultralow density alkali pressurization, this patent readme is: the production method technology that agar is produced in a kind of high temperature ultralow density alkali pressurization provided by the present invention is simple, and cost is low, and the cycle is short, guaranteed the color and luster of agar and improved gel-strength, and mashed dish phenomenon has not taken place in process of production.Its weak point is: it is poorly soluble that this method is produced, and boils in boiling water about ten minutes and could dissolve, and makes troubles to practical application in producing, and limited the range of application of product.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of preparation method of quickly dissolving agar is provided, make it carry out physically modified to agar, the agar solvability of preparation is good, greatly facilitate the production of industrialization streamline in actual applications, for new field and new market have been opened up in the application of agar product.
The present invention is achieved by the following technical solutions, may further comprise the steps:
(1) agar powder and solubility promoter are scattered in the water under agitation condition, boiled several minutes, until dissolving fully;
(2) with consoluet agar colloidal sol cooling, cryogenic freezing is melted then to freezing fully;
(3) will freeze agaropectin dehydration after molten with plate basket pressure filter, be beneficial to next step drying;
(4) under field conditions (factors) or warm air drying, in drying process, pre-configured dispersion agent can be sprayed onto dry thing surface in spray woods mode;
(5) crushing screening obtains quickly dissolving agar.
In the step (1), agar powder is dispersed in concentration in the water in 1～3% scope.Solubility promoter is a kind of in sucrose or the polyol.The addition of solubility promoter is an agar powder 10～50%.
In the step (2), consoluet agar colloidal sol is cooled to below 0 ℃, cryogenic freezing is melted under room temperature to 50 ℃ condition then to freezing fully.
In the step (4), drying temperature is less than or equal to 50 ℃.Dispersion agent is a kind of in Yelkin TTS, the glyceryl monostearate.The concentration of dispersion agent is 1～10%.
In the step (5), with the above pulverizer crushing screening of 100 orders.
The quickly dissolving agar of the present invention's preparation, solvability is good, and the dissolving of following moment of 90 ℃ of conditions greatly facilitates the production of industrialization streamline in actual applications; With the quickly dissolving agar of the present invention's preparation, less investment, cost is low.
The present invention carries out physically modified to agar on the basis of traditional agar production technique, obtain instant quickly dissolving agar in 80 ℃ of hot water, and its tackify thickening properties is good, can substitute some expensive thickening materials.This product can be widely used in thickening material, peptizer, suspension agent, emulsifying agent and the stablizer in the production fields such as food, medicine, chemical industry.
