ABSTRACT:
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 presence of calcium, and they, especially, the HMW pectin, form monovalent cation-based gels at low temperature, which revert back to solution when brought to room temperature. The HMW Aloe pectin-calcium gel is used for controlled release. The monovalent cation-based gel is used as a matrix for storing pharmacological substances and also for antigen and antibody precipitation reaction.
