Abstract
A process for preparing potassium alginate features use of intermediate's solid transfer method. The potassium alginate has low viscosity (1-20 centipoises) of its aqueous solution, having better flowability. Besides food additive, it can be used to prepare health-care nutritive food, pressure-reducing medicine, etc. because of its selective action to reduce blood pressure.
Description
The present invention relates to a kind of make processing method that high molecular, full-bodied foodstuff additive Potassium polyalginate be degraded to lower molecular weight, low viscous Potassium polyalginate and heath food and the medicine of producing 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.
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.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 preparation 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, it is characterized in that viscosity only is the 1-20 centipoise when it is water-soluble, 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 (AR 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;
4. 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 the 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 the invention product Potassium polyalginate of 0.5-2% in candy, millet cake, vermicelli, can or the cooked product, makes nutritious and healthy food.
Embodiment 3 mixes the invention product Potassium polyalginate of 0.5-80% with zanthoxylum powder, pepper powder, leaf mustard powder, monosodium glutamate, salt etc., make nutritional type food flavouring or cooking sauce.
Claims (3)
1. Potassium polyalginate, its rational formula is (C
6H
7O
6K)
n, it is characterized in that viscosity only is the 1-20 centipoise when it is water-soluble, its molecular weight is 2000-50000.
2. method for preparing aforementioned Potassium polyalginate is characterized in that the implementation step of this method comprises:
2.1. 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;
2.2. under condition of stirring, slowly add 30% potassium hydroxide (AP level) aqueous solution, adopt precision test paper and PH meter bidirectional test, when rising to 6-7 gradually by 4, pH value stops to add potassium hydroxide solution, continue to stir so that react completely;
2.3., dry with the reaction soln suction filtration, pulverize, sieve;
2.4. the entire operation process should be carried out under the normal temperature, normal pressure aseptic.
3. can adjust human blood-pressure for one kind, form dietary supplements, medicine, food, seasonings and the cooking sauce of hypotensive effect, it is characterized in that these dietary supplements all contain 0.5-100% invention product Potassium polyalginate as raw material.
