Abstract
New
value-added product was derived from agricultural by-products: rice
bran and soybean meal by means of subcritical water (SW) hydrolysis. The effect of temperature (200–220 °C), reaction time (10–30 min), raw
material-to-water weight ratio (1:5 and 2:5), was determined on the
yields of protein, total amino acids, and reducing sugars in the soluble
products. The suitable hydrolysis time was 30 min and the proper weight
ratio of the raw material-to-water was 1:5. The reaction temperature
suitable for the production of protein and amino acids was 220 °C for
raw and deoiled rice bran, 210 °C for raw soybean meal, and 200 °C for
deoiled soybean meal. The products were also found to have antioxidant
activity as tested by ABTS
+
scavenging assay. In addition, sensory evaluation of milk added with
the hydrolysis product of deoiled rice bran indicated the potential use
of the product as a nutritious drink.
Item Code: De-Oiled-Rice-Bran-Grade2
After crude oil has been extracted
from rice bran, De-Oiled Rice Bran (DORB) is obtained. DORB is widely
used in the manufacture of- Cattle feed,
- Poultry feed,
- Fish feed,
- As fuel for boilers, and
- Used for manufacturing sodium silicate, silica gel, insulation bricks etc (using fully burnt white ash of husk).
Parameter Grade II Protein 11% to 13% Fibre 20% to 25% Sand & Silica 12% to 13% Moisture 10%
