Problems solved by technology

[0003] In order to solve the deficiencies in the prior art that a large amount of water is used to soak the kelp raw material for a long time, the produced alginate has low viscosity and the production cost increases due to the drying of the kelp raw material, a method for producing brown algae using fresh kelp as raw material is provided. In this method, fresh kelp is directly used as the production raw material, which not only saves the drying process of kelp, reduces the production cost, but also has a high yield of alginate, and can produce high-viscosity alginate

Abstract

The related preparation method for algin with kelp comprises: adding 200wt% water to dip kelp for 30min, cutting up, dipping with formaldehyde, and cleaning with water; digesting with Na2CO3 solution to obtain muddy liquid, filtering, diluting, centrifugal separating to obtain clear glue solution; adding CaCl2 to obtain calcium alginate; using diluted HCl to remove calcium; neutralizing, dewatering, grinding, adding CaCO3 powder, granulating, drying, cooling, and grinding to obtain the product. This invention improves yield with low cost.

Description

technical field [0001] The invention relates to seaweed chemical technology, in particular to a method for producing alginate from fresh kelp. Background technique [0002] Alginate is a collective name for alginic acid, alginate and organic derivatives of alginic acid. Since its inception, alginate has been widely used in printing and spinning, food, medicine, chemical industry, agriculture, etc. According to its viscosity, alginate can be divided into: ultra-low viscosity, low viscosity, medium viscosity, high viscosity and ultra-high viscosity alginate. At present, dry kelp is generally used as raw material for the production of alginate. During the drying and storage of kelp, due to the The influence of enzymes, microorganisms and other physical and chemical factors causes the viscosity of alginate to drop greatly, making it impossible to produce high-viscosity glue. Domestic manufacturers use dried kelp as raw material and follow the traditional process to produce algi...
