Study on the technology of algin extraction from kelp and preparing edible fresh wrap

摘要

The extracting technology of algin from kelp and the preparing technology of edible fresh wrap from algin are reported by this paper. Firstly, the crude algin was extracted from kelp, which was purified by the methods including solid-liquid separation, precipitation, bleaching, transformation, dehydration and etc.. Besides, resulting from the orthogonal experiment, we determined the optimal concentration, time and temperature of digestion. Then, based on the good ductility of algin, we has prepared the edible fresh wrap and explored the different influence factor of preparing the film.
