Abstract
1. Highly purified pectin preparation from papaya and Indian gooseberry have been shown to form typical metal complexes and yield poly-galacturonic acid, arabinose and galactose on acid hydrolysis. 2. The viscosities of the pectin solutions were of the order usually found for long chain solvated polymers. Up to 0.5% concentration of pectin there was no visible change in relative viscosity with increase in temperature. 3. The formation of jellies under different concentrations of sugar, acid and pectin has been studied.
