Abstract
The invention discloses production technology of low-temperature instant-dissolving agar. The technology includes the steps: adding cosolvent into seaweed glue liquid or adding water into agar and cosolvent, boiling, dissolving completely, processing through a high-pressure or superpressure device, dehydrating through a plate-and-frame filter press, microwave drying to sterilize till an appropriate amount of water is left, smashing and sieving to obtain low-temperature instant-dissolving products (physical modified agar); or processing through the high-pressure or superpressure device and spray-drying to obtain the products (physical modified agar); or processing through the high-pressure or superpressure device, superfreezing, thawing, filter-pressing, extruding through a screw compressor, airing and smashing to obtain the products (physical modified agar). The low-temperature instant-dissolving agar produced by using the technology method has the advantages of being fast in dissolving at the low temperature.
Description
Technical field
The present invention is a kind of manufacturing technology relating to requisite agar in foodstuffs industry, daily chemical industry, biotechnology, pharmacy, scientific research.
Technical background:
Seaweed gel is the polysaccharide material extracted from marine algae plant, belongs to lyophilic colloid.Important commodity seaweed gel mainly contains carrageenin, agar, alginates etc.Seaweed gel has good gelation, thickening property and water-retentivity, is colloid indispensable in foodstuffs industry, daily chemical industry, biotechnology, pharmacy.
Agar also claims " agar-agar ", and be the polysaccharide obtained through refining from the marine red alga such as gelidium, fragrant plant mentioned in ancient texts plant, its main component is the sulfuric acid ester of poly semi-lactosi.Agar has special gelling properties because of it, has been widely used in the fields such as food, medicine, chemical industry, weaving, national defence, scientific research.Agar is classified as generally regarded as safe product by U.S. food drug regulations already, gets permission to be loaded among food chemistry product pharmacopeia as special topic as foodstuff additive.Food and Argriculture OrganizationFAO in 1973 and the World Health Organization evaluate thinks that everyone per kilogram of body weight every day of agar allows absorption without restriction, so agar is the foodstuff additive of use safe, without restriction.
Gelling characteristics that agar has not only utilize by various foodstuff production, and have also been obtained on microbiological culture media and apply widely.But conventional agar-agar more than 95 DEG C, just can only dissolve for 10-15 minute completely; Need high temperature and longer time when heating for dissolving, become large defect during its application.
No. 200510112224th, Chinese patent application discloses a kind of agar production technique, agar powder and solubility promoter are scattered in water by this technique under agitation, then by consoluet agar colloidal sol cryogenic freezing to fully charge, then melt, dehydration, under the condition of natural condition or warm air drying, is sprayed onto dry thing surface by pre-configured dispersion agent in spray mode, obtain quickly dissolving agar, the solvent temperature of gained agar can be reduced to 80 DEG C.
Along with the fast development of foodstuffs industry, also more and more come urgently, how to prepare a kind of agar of low solvent temperature, become this area problem demanding prompt solution to the demand of the agar of excellent property.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of production technology of low-temperature instant agar is provided, it is made to carry out physically modified to agar, the agar dissolution in low temperature produced is good, greatly facilitate industrialization production line balance in actual applications, meet the requirement of low-temperature production process, the application for agar opens new field and new market.
The present invention is achieved by the following technical solutions, comprises the following steps:
(1) agar and solubility promoter are scattered in water under agitation, boil several minutes, until dissolve completely; Or operation before the press filtration connecing traditional agar production technique, solubility promoter is joined in the glue waiting for press filtration, mix to solubility promoter and dissolve completely;
(2) by the mixed solution of the consoluet colloid that obtains in step (1) and solubility promoter, operate according to any one in following three kinds of processing modes:
A. by the mixed solution of the consoluet colloid obtained in step (1) and solubility promoter by high pressure or extra-high tension unit process, spray-dried granulation, obtains low-temperature instant agar;
B. by the mixed solution of the consoluet colloid obtained in step (1) and solubility promoter by high pressure or extra-high tension unit process, mono-frozen machine is utilized to carry out quick freezing to-30 to-50 DEG C, then by microwave quick-thawing, by the plate-and-frame filter press filter-press dehydration of the mixed solution after freeze thawing, extrude under the film singe screw that press filtration is obtained or twin screw extruder heating, by microwave or warm air drying, pulverize and sieve, obtain low-temperature instant agar;
C. by the mixed solution of the consoluet colloid obtained in step (1) and solubility promoter, by high pressure or extra-high tension unit process, renew the plate-and-frame filter press press filtration operation of the traditional processing technology connecing agar and follow-up film airing or oven dry, film pulverizes and sieves operation, obtains low-temperature instant agar.
The aqueous solution of step (1) described agar or marine alga; The colloid concentration be dissolved in water is 1-10%;
Step (1) described solubility promoter comprises one or more the mixture in salt, sugar and emulsifying agent, and described salt can be sodium salt, sylvite or phosphoric acid salt, and described sugar can be sucrose, glucose, Xylitol or dextrin; Described emulsifying agent is sucrose ester or this Pan; The addition of solubility promoter is the 5-90% of agar;
The traditional processing technology of step (1) described agar refers to that marine alga is sorted, clean, boil glue, impurity screening, with plate-and-frame filter press water is separated with colloid, film airing or oven dry, pulverize, sieve, the step of finished product;
Step (2) described high pressure or extra-high tension unit are high pressure or superhigh-voltage homogenizing machine or mulser, and its pressure is 40-150MPa;
The working temperature of step (3) described screw extrusion press is for being less than 110 DEG C.
Production technology of the present invention has the following advantages: the agar solvability prepared is good, and required solvent temperature is low; The agar product that the present invention produces, belongs to physically modified, can not change the chemical property of material, meet the regulation of " the law of food safety " and relevant laws and regulations, is applicable to foodstuffs industry and the use of other industry;
Agar solvent temperature is before modified >=95 DEG C, 15 minutes time; Modified through present method, agar solvent temperature is≤70 DEG C, and the time is less than 8 minutes; Meanwhile, the gelation rate of agar also can by the proportioning of adjustment solubility promoter, and be effectively controlled (time delay is slowed down or accelerated fast solidifying)
