PROCEDURES FOR OBTAINING MOVIES FROM ADENANTHERA PAVONINA GALACTOMANANES AND GALACTOMANAN BLENDAS WITH OTHER BIOPOLYMERS

摘要

procedures for obtaining films from adenanthera pavonina galactomannans and blends of this galactomannans with other biopolymers. The present invention relates to the production of galactomannan films from adenanthera pavonina (2a) seed endosperms, as well as galactomannan with other biopolymers. adenanthera pavonina l. (1), belonging to the family fabaceae and subfamily mimosoideae. The invented process essentially consists of extracting the polysaccharide from the adenanthera pavonin endosperm (2b), solubilizing, adding crosslinking agent or not, freezing the solution and further lyophilization. Extracted galactomannans from adenanthera pavonina seed endosperms are obtained after heating the seeds in boiling distilled water for 20 minutes, followed by swelling for 12 hours.l The endosperms are then separated manually, the integuments are removed and then removed. The endosperms are separated from the embryo and stored under refrigeration prior to use. endosperms are solubilized and homogenized in water or aqueous acetic acid solution followed by centrifugation at 8000 rpm for 15 min. The object of the present invention is to produce films of galactomannans (3) obtained from adenanthera pavonina seed endosperms and blends of this galactomannan with other biopolymers. adenanthera pavonina seeds are collected, washed, environmentally dried and stored until use. The developed process is simple, efficient, inexpensive and does not require any purification step for the production of films and blends; As it is a biodegradable galactomannan, it eliminates risk to the environment, as well as providing optimization of process costs with elimination of the purification step.
