Description |
Composition of nutraceuticals and nutrients of two varieties of rough rice subjected to biotransformation by
germination for 120 h, drying and dehusking, compared to respective control brown rice. An increase in the content
of free sugars and soluble fiber, and decrease in insoluble fiber and fat was observed in nutrient composition.
Different forms (d, g, & a) of tocotrienols and tocopherols were present in both control and biotransformed brown
rice. g-tocotrienol was the major form and its content increased and the total tocopherols, which was low in content,
decreased. The g-oryzanol content and its fractions, namely, cycloartenyl ferulate and 24-methylene cycloartenyl
ferulate, did not show any significant alterations. However, the total antioxidant activity decreased. Scanning
electron microscopic examination showed enlargement and distinct appearance of starch granules in the
biotransformed rice. Biotransformed brown rice was also found to be superior to polished rice in nutritional and
nutraceutical qualities.
