Bioactive benefits of resveratrol in the diets have attracted

extensive interests of the public. Peanut is one of the potent

natural sources of resveratrol. In this study, germination of peanut

kernels to enhance resveratrol biosynthesis and preparation of

sprouts as a functional vegetable was conducted. When the rehydrated

kernels of three peanut cultivars were germinated at 25 degrees C and

relative humidity 95% in dark for 9 days, resveratrol contents

increased significantly from the range of 2.3 to 4.5 microg/g up to

the range of 11.7 to 25.7 mug/g depending upon peanut cultivar. In

comparison with the sprout components, resveratrol contents were

highest in the cotyledons, slightly lower in the roots, and not

detected in the stems. When the sprouts were heated in boiling water

for 2 min, resveratrol contents varied in a limited range. Methanol

extracts of the freeze-dried sprouts exhibited potent 1,1-diphenyl-2-

picryl-hydrazyl scavenging activity and antioxidative potency against

linoleic acid oxidation. These activities increased with an increase

of germination time. After 9 days of germination, total free amino

acid, sucrose, and glucose contents increased significantly while

crude protein contents decreased and the large sodium dodecyl sulfate

polyacrylamide gel electrophoresis protein molecules of the kernels

were extensively degraded. From a practical viewpoint, it is of

potency to prepare peanut sprouts as a functional vegetable. "

Bear in mind that aflatoxin occurs in moist conditions. Sprouting

entails moist conditions. So if you see any mold, throw it out. One

source seems to suggest that aflatoxin is bright yellow in color.

But I have not found confirmation of that.
