K. Vijayakumari et al., EFFECT OF SOAKING, COOKING AND AUTOCLAVING ON PHYTIC ACID AND OLIGOSACCHARIDE CONTENTS OF THE TRIBAL PULSE, MUCUNA-MONOSPERMA DC EX WIGHT, Food chemistry, 55(2), 1996, pp. 173-177
The effects of soaking, cooking and autoclaving on the levels of phyti
c acid and oligosaccharides, raffinose, stachyose and verbascose, pres
ent in two germplasm seed materials of Mucuna monosperma collected fro
m Kerala and Tamil Nadu states, were investigated. The loss of phytic
acid was found to be higher in distilled water soaking compared to sal
t water soaking in Kerala germplasm. There was no significant reductio
n in content of raffinose during soaking in distilled water in Tamil N
adu germplasm. Cooking for 3 h effected significant reduction of phyti
c acid, raffinose, stachyose and verbascose in both the germplasms stu
died. The percentage loss of oligosaccharides with autoclaving was hig
her than with cooking. These results revealed that autoclaving was mor
e effective in eliminating the contents of phytic acid and oligosaccha
rides, in both the germplasms of the Indian tribal pulse, Mucuna monos
perma, presently studied.
