Mc. Varadaraj et A. Horigane, BIOCHEMICAL CHARACTERISTICS AND MICROBIAL PROFILE DURING SPROUTING PROCESS IN GRAINS OF ELEUSINE-CORACANA L. (FINGER MILLET), Journal of agricultural and food chemistry, 46(5), 1998, pp. 1719-1726
The associated biochemical and microbiological changes during sproutin
g in the seeds of Eleusine coracana L. (finger millet) common to India
were studied. The initiation of physiological process as well as an i
ncrease in weight of seeds (0.6-fold) occurs during the stage of preso
aking for 8 h at room temperature (23 degrees C). The levels of solubl
e protein, total soluble sugar, proteinase, and ol-amylase activities,
which were 1.22 mg, 0.6 mg, 0.44 unit of activity, and 14 units per g
ram of resting seed, respectively, increased significantly to 1.38 mg,
1.53 mg, 2.89 units, and 404 units per gram during sprouting for 48 h
at 25 degrees C. The level of globulin increased from an initial leve
l of 0.15 to 0.75 mg g(-1) of seed. The electrophoretic mobility of is
olated globulins from presoaked and sprouted (48 h at 25 degrees C) se
eds shows more bands relative to the resting seeds as determined by so
dium dodecyl sulfate-polyacrylamide gel electrophoresis. Sedimentation
analysis of globulin and prolamin fractions indicates a probable self
-associating system. During sprouting, there was the buildup of lactic
acid bacteria, a desirable microflora. The associated changes in the
seeds of finger millet can lead to the development of traditional food
s with beneficial attributes.
