Description
Technical field
The present invention is a kind of manufacturing technology relating to requisite carrageenin 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.
Carrageenin is also known as " carrageenin ", and be the polysaccharide obtained through refining from the plants such as marine red alga plant Eucheuma muricatum (Gmel.) Web． Van Bos．, carrageen, its main component is the sulfuric acid ester of poly semi-lactosi.Carrageenin 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.Carrageenin 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 carrageenin is the foodstuff additive of use safe, without restriction.
Carrageenin, because its raw material sources are relatively wider, cost is low, is therefore widely used in the aspects such as food, household chemicals, biotechnology, medicine.In general, carrageenin is insoluble in the water of less than 75 DEG C, and this causes very large puzzlement in the application of industrial aspect to it.
Along with the fast development of foodstuffs industry, also more and more come urgently, how to prepare a kind of carrageenin of low solvent temperature, become this area problem demanding prompt solution to the demand of the colloid of excellent property.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of technology of preparing of low-temperature instant carrageenin is provided, it is made to carry out physically modified to carrageenin, the colloid 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 carrageenin opens new field and new market.
The present invention is achieved by the following technical solutions, comprises the following steps:
(1) carrageenin and solubility promoter are scattered in water under agitation, boil several minutes, until dissolve completely; Or operation before the press filtration connecing carrageenin traditional processing technology, 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 carrageenin;
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 carrageenin;
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 and follow-up film airing that connect traditional processing technology or oven dry, film pulverizes and sieves operation, obtains low-temperature instant carrageenin.
The aqueous solution of the described OK a karaoke club rubber powder of step (1) 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 carrageenin;
The traditional processing technology of step (1) described carrageenin 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.
Preparation method of the present invention has the following advantages: the carrageenin solvability prepared is good, and required solvent temperature is low; The colloid products 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;
Carrageenin is before modified >=75 DEG C, 10 minutes time; Modified through present method, carrageenin is≤60 DEG C, and the time is less than 6 minutes.Meanwhile, the gelation rate of carrageenin also can by the proportioning of adjustment solubility promoter, and be effectively controlled (time delay is slowed down or accelerated fast solidifying)
