The Development of a New Method to Detect the Adulteration of Commercial Aloe Gel Powders

  • Published : 1998.10.01

Abstract

Simple and accurate methods to detect the adulteration of commercial aloe gel powder were developed. Crude polysaccharide in aloe gel powder was isolated by precipitating with excess ethyl alcohol and total hexose in isolated polysaccharide was determineded by dubois assay. After hydrolysis of non-dialysable polysaccharides, resultant free sugar was determined by gas chronmatography for sugar recogniton and ash contents was very low while the content of total hexose was very high. And polysaccharides of these products revealed typical dextran pattern, therefore, these products could be identified that adulterated with commercial maltodextrin. The content of maltodextrin in adulterated product was determined by HPLC and TLC analysis which could be adopted as a part of a certification process.
