Yawei Ni, Kenneth M Yates, Ryszard Zarzycki: Aloe pectins. Carrington Laboratories, Hitt Chwang & Gaines P C, July 27, 1999: US05929051 (23 worldwide citation)

Pectins from gel and rind cell wall fibers of Aloe vera are extracted, isolated and identified. Two classes of Aloe pectin are obtained: the high-molecular-weight (HMW) pectin and the low-molecular-weight (LMW) pectin. Aloe pectins have a low methoxyl (LM) content. Aloe pectins form gel in the prese ...
