In order to determine the change rule of polysaccharides content in fresh rice grains at different mature stages, the polysaccharides were extracted from fresh rice grains at different mature stages by ultrasonic-microwave synergistic extraction method. The composition of polysaccharides was analyzed by HPLC, and the antioxidant activity of polysaccharides was determined by antioxidant test in vitro. The results showed that the content of polysaccharides in fresh rice was the highest at the stage of late milk, up to 46.89 mg/g. Mannose, rhamnose, glucuronic acid, galacturonic acid, glucose, galactose, xylose, arabinose and fucose were the main components of polysaccharides at this …

Globally, rice producers are faced with the temporal problem of deciding the optimal time to harvest rice. When harvested, paddy rice is typically at a harvest moisture content (HMC) between 15% and 22% and subsequently dried by the mill to a moisture content (MC) of 12.5%. Riceland Foods Inc., the largest miller of rice in the world, uses a stair-step pricing model to charge farmers to dry, which can complicate the timing of harvest as producers try to balance the tradeoff of minimizing drying costs by waiting to harvest at lower HMC vs. maintaining higher rice quality typically observed when …
