PHYSICO-CHEMICAL AND MICROBIAL STUDIES OF LANNEA GUM

Abstract

Lannea gum (Gumpena gum) powder started charring at a temperature of 258.6 ° C and decomposed at 327° C. Moisture content of GG powder was
found to be 8.52 ± 0.59 %. The pH of the 1% w/v GG (Gumpena gum) powder mucilage was found to be 6.1 to 6.5. The volatile acidity, loss on
drying, loss on ignition, and residue on ignition of GG powder was found to be 3.7, 9.64, 98. 13 and 1.77 respectively. Gumpena gum sample were
analyzed for microbial growth and results showed that GG did not support microbial growth and free from all pathogen organisms. Micromeritic
studies of the gumpena gum powder showed good flow and compressibility characteristics. Results of the physico-chemical properties of gumpena
gum showed the acidic nature of gum with considerable swelling and water retention capacity. As there is chance of microbial growth in natural
polymers, microbiological studies were conducted in samples of gum and the results revealed the presence of microorganisms will within the limits as
per I.P. and absence of harmful pathogens and gum does not support any further growth.
