Problems solved by technology

At present, although there are known extraction techniques for extracting kelp cellulose from kelp and kelp residue, cellulase or protease is generally used for high-temperature enzymolysis at a temperature above 50°C. Molecules will also be degraded due to intense enzymatic hydrolysis conditions, resulting in low kelp cellulose content in the extract and low extraction yield, and the molecular weight of kelp cellulose is not uniform, which affects the quality of kelp cellulose

Abstract

The invention discloses soluble kelp cellulose water and a preparation method of the soluble kelp cellulose water. The preparation method comprises the steps of: preparing kelp dietary fiber by flocculation, decalcification, bleaching and washing and the like in kelp slag; then carrying out steam explosion to obtain insoluble kelp cellulose; then adding low temperature cellulase for enzymolysis in a water bath at 25-35 DEG C to obtain the soluble kelp cellulose; adding 1-300g of soluble kelp cellulose in drinking water per liter, thus obtaining the kelp cellulose water. According to the invention, and enzymolysis is carried out at a normal temperature by using low temperature cellulose enzyme, and the soluble kelp cellulose with uniform molecular weight, high cellulose content, and high specific retention and expansibility of cellulose is obtained to prepare the soluble kelp cellulose water. After being drunk, the soluble kelp cellulose water has effects on improving and treating constipation of human body and has excellent functions. The flavor of drinking water such as purified water or mineral water added with the kelp cellulose is not changed, and a novel nutritional health care beverage is provided.

Description

technical field [0001] The invention relates to the technical field of reuse of kelp industrial waste, in particular to a soluble kelp cellulose water and a preparation method thereof. Background technique [0002] Kelp is a large-scale brown algae that is widely distributed along the coast of my country, but it is mainly produced in the coasts of Shandong and Liaoning provinces in my country. The output and scale of kelp planting in my country ranks first in the world. In 2009, the output of dry kelp in my country reached 6.0×10P 5P t, accounting for more than 50% of the world's total output. Kelp is rich in alginate, cellulose, hemicellulose, vitamins and minerals, etc. In addition to being used for direct consumption, kelp is one of the main raw materials for the brown algae industry. In my country, kelp processing has formed an industrial system with alginate, mannitol, and iodine as the main products. In recent years, due to fierce market competition, low added value...
