ENZYMATIC LYSATE OF GULFWEED AND BUNDLE AND PREPARATION METHOD THEREOF

摘要

A method for preparing an enzymatic lysate of gulfweed and bundle is provided to liquefy more than 80% of the gulfweed and bundle and obtain the lysate which is not gelated even if it is concentrated into 40% and is usefully used as a food composition and a cosmetic composition due to high fiber content. A method for preparing an enzymatic lysate of gulfweed and bundle comprises the steps of: (a) washing and desalting the gulfweed or bundle; (b) adding a first enzyme consisting of endo-beta1,4-glucanase, alginic acid lyase and exocellulose to the gulfweed or bundle to decompose firstly the gulfweed or bundle under pH of 4-7.5 at a temperature of 30-60 deg.C for 10-13 hours; and (c) adding a second enzyme consisting of arabanase, cellulase and beta1,4-glucanase to the material obtained from the step(b) to decompose secondly it under pH of 4-7.5 at a temperature of 30-60 deg.C for 4-6 hours. The method further comprises a step of heat-treating the material obtained from the step(c) and then filtering the heat-treated material.
