Discovering new rice varieties with antioxidant capacity

Four new varieties of rice in Afghanistan have been researched by Vietnamese scientists to find a high ability to inhibit oxygen and protein and lipid nutrition.

The new study was conducted by Vietnamese scientists at Hiroshima University, the Agricultural Research Institute and Nguyen Tat Thanh University in Vietnam, in collaboration with Afghanistan and published on MDPI's Agriculture magazine on August 1. .

Four typical rice varieties grown in Afghanistan include: Attai-1, Jalalabad-14, Shishambagh-14 and Zodrass . The scientists conducted a cross-sectional examination of the rice grain using a scanning electron microscope. The results show that, not only are the antioxidant advantages, these 4 rice varieties have outstanding advantages in grain yield and grain quality. Of which Jalalabad rice variety - 14 contains the highest amount of oxidants, Attai-1 has lower levels of amyloza, protein and lipid than Jalalabad - 14.

The scientists applied DPPH and ABTS method (specialized chemical for oxidation test) to test the antioxidant capacity of these 4 rice varieties. Results showed that Jalalabad - 14 rice had the highest antioxidant index of 2574 µg / mL and 2970 µg / mL, higher than the index of germinated rice and cracked rice (in the ethyl acetate segment), ranked behind are Zodrass, Shishambagh -14 and Attai - 1.

Protein and lipid content, antioxidant capacity are the main indicators to evaluate nutritional value in rice grains. Indicators in different rice varieties are caused by genetic factors or external environmental influences. These factors will impact directly on the change in yield and quality of rice.

Afghanistan is a country with many droughts, often having difficulties in agricultural irrigation. The discovery of the superior advantages of these four rice varieties contributes to reducing the rate of crop failure, improving agriculture. Through the discovery of the outstanding nutritional and yield characteristics of these four new rice varieties, breeders will consider using these varieties in a strategy to expand and breed hybrid rice varieties. Other for better productivity and quality. Thereby benefiting the supply of sustainable food sources and improved nutrition from rice.
