Abstract: Gum is
important natural biopolymers derived from biological system under stress
situations, being used as principal components in food, pharmaceutical
industries and plays a key role in social and livelihood of tribal communities.
The joint Expert Committee for Food Additives (JECFA/FAO) defines gum kataya as
the dried gum exudates obtained from Sterculia urens Roxb. and other related
species of Sterculia family Sterculiaceae. The gum harvesting methods and
processing techniques currently used are traditional and injurious. Hence, the
sustainable harvesting of biopolymers through scientific techniques is
essential to improve the quantity and quality of produce and it also need value
addition to improve their marketability. Therefore, the study was undertaken in
ICAR network project at IGKV, Raipur (CG) to find out the scientific bio safe
techniques to extract biopolymers for potential production in Karaya (Sterculia
urens Roxb.), Dhawara (Anogeissus latifolia Roxb.) and Drumstick (Moringa
olefera). Plant physiological method (using graded concentration of gum
enhancer ethephon by drill method) compared with mechanical and traditional
techniques of tapping of biopolymers for the quantitative and qualitative
analysis. It was observed that the tree inclination, tree elevation, direction
of sun and time of application of ethephon, atmospheric temperature, relative
humidity have significant impact on exudation of biopolymers. Injecting
ethephon via drill method @ 3.9% in 4 ml applied in two concomitant doses from
last week of March to second week of May (temperature > 38-40 "C, RH
< 40-45%) in one month intervals was found significantly superior and safe
for potential production in Karaya and Dhawara. However, ethephon@0. 39% in 4ml
applied during second week of March to May was found significantly superior in
drumstick when applied in month of Feb to April. The quality of produce
obtained through drill method was also found superior as compared to
traditional and mechanical methods of tapping these trees.
