Flocculating Activity of the Mucilage Extracted from Aloe vera Linne
알로에 배라 점질물의 무기물 응집활성
Abstract
For the purpose of screening the functionality in aloe, the mucilage from Aloe vera Linne was prepared by extraction of mucilaginous parenchyma with ethanol followed homogenation, filtration and centrifigation. Flocculability of this mucilage from Aloe vera L. was investigated and the identification fro flocculating active materials were carried out. The mucilage exhibited an excellent flocculability for 1% bentonite and 5,000 ppm kaolin suspensions. The good correlations between mucilage volume(concentration) and flocculability for 1% bentonite suspension were obtained. The flocculated volume or flocculation rate was affected depending upon the degrees of processing such as a heat treatment and purification. A major component showing the flocculaing activity was considered as a highly polymerized polysaccharide having flocculating activity was about 1,000,000 daltons.
