Abstract
The present invention discloses potassium alginate which is a novel product, a preparation method and application. The potassium alginate of the present invention is prepared by an intermediate body solid phase conversion method. When the potassium alginate is dissolved in water, the viscosity is only from 1 to 20 centipoises. Compared with the viscosity of an original traditional product, which is 150 centipoises, the fluidity is better. The potassium alginate can be used as food additives. According to the function of selectivity blood pressure reduction of the potassium alginate, the potassium alginate can be prepared into various nutrition and health care products, antihypertensive medicine, nutrition food, condiments which have the health care function, cooking seasoners, etc. The potassium alginate and the preparation method of the present invention are simple, convenient and feasible, the application is wide, and the potassium alginate can be applied to food, beverages, cooking seasoners, medicine, etc.
Description
The present invention relates to a kind of high molecular, full-bodied foodstuff additive Potassium polyalginate of making and be degraded to lower molecular weight, low viscous Potassium polyalginate, and preparation technology's method of Potassium polyalginate and heath food and the medicine produced with this low viscosity Potassium polyalginate.
Potassium polyalginate (Polassium Alginate) claim potassium alginate again, is a kind of fibrous matter that is contained in many marine plants, the alginate that is refined through chemical process.When it is water-soluble, have very strong toughness, so just regarded as foodstuff additive by The World Health Organization (WHO) before very early, its consumption and use range there is no clearly restriction, almost can determine on demand.
In the CN1097307A application for a patent for invention specification sheets, the marine alga food for decreasing fat that a kind of main component is oligomeric Potassium polyalginate is disclosed.Its preparation method is commercially available medical alginic acid to be soaked the back add 6～7N hydrochloric acid, make alginic acid degraded becoming oligopolymer, wash depickling with water, the saturated alcohol solution that adds KOH then, generate oligomeric Potassium polyalginate, pH value is stabilized at 8 o'clock, through washing, filter, add dehydration of alcohol, filter dry-pressing press for extracting juice, oven dry, pulverizing, makes Potassium polyalginate.Adopt above-mentioned preparation method, in fact can't obtain the Potassium polyalginate product.Because the Potassium polyalginate particularly oligopolymer of Potassium polyalginate is a kind of water-soluble material, Potassium polyalginate can become alginate solution through washing, therefore after generating oligomeric Potassium polyalginate, adopt again and wash, filter, add dehydration of alcohol technology, can't make Potassium polyalginate at all, so above-mentioned prior art just discloses the notion of oligomeric Potassium polyalginate, and can't provide molecular formula, molecular weight and the viscosity thereof that oligomeric Potassium polyalginate is determined.
US3879168 discloses and has a kind ofly prepared high viscosity calcic, sodium or potassium and hydrogen ion is the method for 4: 5: 1 heteropolymers.This heteropolymer is suitable for preparing surgical garments, and concrete technology is that to adopt calcic be that 2～6% alginic acid material contacts with potassium hydroxide solution.This method and the present invention do not belong to same technical field, and its goal of the invention is a kind of surgical garments fiber of preparation.
It is 2～5 that the flat 6-237783A of JP discloses a kind of polymerization degree, and molecular weight is 100～1800 daltonian Potassium polyalginate oligosaccharides.This oligosaccharides only is fit to add to a kind of heath food of preparation in the food.
EP0174101A discloses a kind of low viscosity Potassium polyalginate, is suitable as the carrier of pyridine four herbicidal salt agent.
Contriver and co-worker thereof find that in 1986 Potassium polyalginate except can be used as foodstuff additive, also has a kind of health protection effect of not known by the people as yet, i.e. its hypotensive effect.Test finds that grownup's every day, edible 6-8 gram (water content is less than 10%) Potassium polyalginate can produce optionally hypotensive effect to hypertension.Generally speaking, only need feed 2 grams, human body is just had the effect of preventing hypertension.Simultaneously,,, get rid of intravital heavy metal ion, increase ight soil amount and prevention of arterial arteriosclerosis etc. and also play a part good for eliminating human body waste because Potassium polyalginate is the macromolecular fibre material.
According to the Potassium polyalginate that classical processing method is extracted, about 150 centipoises of the viscosity when soluble in water, this salt is suitable for doing the thickening agents of food.If utilize this salt to prepare medicine or nutritive health products, can give to take to make troubles.Therefore, seek a kind of new preparation method, produce a kind of lower molecular weight, low viscous Potassium polyalginate, make it can cook foodstuff additive, can be used for making medicine or dietary supplements again, improve Food Quality simultaneously, when being new developing direction in this technical field.
The purpose of this invention is to provide a kind of lower molecular weight, low viscosity (1～20 centipoise) Potassium polyalginate and preparation technology's method thereof, and adopt this salt to prepare related drugs and nutritive health-care food.
Technical scheme of the present invention is to realize like this.
A kind of Potassium polyalginate, its rational formula are (C
6H
7O
6K) n is characterized in that viscosity only is 1～20 centipoise when it is water-soluble, and its molecular weight is 2000～50000.
A kind of method for preparing aforementioned Potassium polyalginate, the method that the contriver adopts is an intermediate alginic acid solid phase conversion method, the implementation step of this law comprises:
1, get 1000 gram alginic acids (more than the CP level), add 1.5 times of amount 95～100% medicinal alcohols (more than the CP level), stirring makes alginic acid be disperse phase in alcohol under the room temperature;
2, potassium hydroxide (AP level) aqueous solution of slow adding 30% under condition of stirring adopts precision test paper and PH meter bidirectional test, stops to add potassium hydroxide solution when pH value rises to 6～7 gradually by 4, and it is complete with question response to continue stirring;
3, with the reaction soln suction filtration, dry, pulverize, sieve;
The working conditions of entire operation process should be aseptic, normal temperature, normal pressure.
By the Potassium polyalginate that above-mentioned intermediate solid phase conversion method makes, molecular weight reduces greatly, and water-soluble viscosity only is 1～20 centipoise.This Potassium polyalginate can obtain to use in following several respects:
Preparation antihypertensive drugs, preparation nutritious and healthy food, preparation healthcare products, preparation are the cooking sauce of main raw material with this salt.
Intermediate solid phase conversion method provided by the invention is compared with the preparation method of the Potassium polyalginate of classics, simple and easy to do, satisfy the needs of producing the required Potassium polyalginate of the low viscosity aqueous solution, simultaneously, also met the relevant regulations and the specification of quality of national health inspection department.
Be embodiment provided by the invention below.
Embodiment 1 is a raw material with product Potassium polyalginate of the present invention, and the Potassium polyalginate of employing 30% is equipped with vehicle and can makes tablet, perhaps adopts 100% Potassium polyalginate to make the antihypertensive drugs or the healthcare products of various formulations such as capsule, electuary.
Embodiment 2 is added on 0.5～2% invention product Potassium polyalginate in candy, millet cake, vermicelli, can or the cooked product, makes nutritious and healthy food.
Embodiment 3 mixes 0.5～80% invention product Potassium polyalginate with zanthoxylum powder, pepper powder, leaf mustard powder, monosodium glutamate, salt etc., make nutritional type food flavouring or cooking sauce.
