A. Sumathi et al., ELABORATION OF AMYLASE ACTIVITY AND CHANGES IN PASTE VISCOSITY OF SOME COMMON INDIAN LEGUMES DURING GERMINATION, Plant foods for human nutrition, 47(4), 1995, pp. 341-347
The effect of germination upto 120 hours on malting loss, amylase acti
vity and viscosity of nine common Indian legumes was investigated. The
amylase activity increased on progressive germination in all legumes,
the increase being particularly high for green gram, horse gram, moth
bean and black gram. Malted samples had lower cooked paste viscosity
than native ones. Samples with high amylase activity exhibited proport
ionately lower viscosity. Maximum reduction in viscosity was observed
in green gram, followed by moth bean, horse gram, black gram and cowpe
a within 48 hours of germination. Malting losses ranged between 12 to
27 percent over a period of 48 hours in all legumes. Germination beyon
d 48 hours resulted in considerably higher malting losses without much
effect on viscosity.
