Abstract

The invention discloses a production process of super-low-viscosity magnesium alginate.The production process is characterized by including following steps: (1), cleaning and chopping brown alga, adding water of five times and 15% composite magnesium salt, and disposing in a high-temperature high-pressure reaction kettle for degradation for 50-60 min; (2), roughly filtering to obtain magnesium alginate rough extract; (3), adding activated carbon into the magnesium alginate rough extract for adsorption and decoloring, and filtering to obtain primarily-purified extract; (4), performing further purifying and impurity removing on the primarily-purified extract through ion exchange resin adsorption to obtain purified extract; (5), concentrating the purified extract; (6), spray-drying concentrate to obtain solid powder of magnesium alginate.Rotary viscosity of 1% glue liquid of magnesium alginate prepared by the production process at 20 DEG C is 5-10 mPa.s.

Description

technical field [0001] The invention relates to a production process of ultra-low viscosity magnesium alginate. Background technique [0002] Magnesium alginate is a monovalent alginate, which is a macromolecular polysaccharide extracted from kelp and other brown algae plants. It has excellent characteristics such as natural, green, and high biocompatibility. Salt products are quite different. Ultra-low viscosity magnesium alginate is the only bivalent non-gelling alginate, which has the characteristics of easy absorption and can reduce blood lipids. It can be used as the main component or ingredient of health food or health nutrition food, regulation and prevention Hypertension, delay cardiovascular aging, improve microcirculation. [0003] At present, there are few domestic enterprises producing ultra-low molecular weight magnesium alginate. The production technology of this product is immature. Conventional magnesium alginate production technology has a long production ...
