High phenolic and mineral compound of rice lines as an alternative healthy food to maintain human health under climate change

Abstract

Abstract Climate change promotes variances diseases in rice plant and humans. Unpredicted weather due to climate change caused an optimal condition for vectors, pathogens and hosts to be survive and reproduced themselves. Phenolic compounds have the ability to act as antioxidants that can counteract free radicals and prevent various diseases in humans. The mineral content of Zn and Fe is also very useful to anticipate anaemia, stunting and immune boasting in humans being. The research was conducted by tested 14 promising lines and 2 check varieties in the farmer field. The research was followed randomized block design with 3 replications. The grains of each line and checks were analysis in the laboratory for mineral content and phenolic content. The results showed that there were several rice lines that had good yield potential with high antioxidant and mineral content, including IR83663-20-3-2-2, B5640H-MR-1-PN-1, and BH39D-MR-PN-1. IR83663-20-3-2-2 has a high Zn content in rice that is 23.76 ± 2.03 ppm, with grain yield of 5.39 t ha-1, and early maturity. While the B5640H-MR-1-PN-1 line is a black rice and has a phenolic compound of 4801.00 ± 0.00 mg AAE 100−g of brown rice. The BH39D-MR-PN-1 line is a red rice which has a higher total phenolic compound up to 5743.35 ± 9.74 mg AAE 100−g of brown rice and Zinc mineral content of 23.66 ± 0.25 mg kg−1. The availability of specialty rice varieties with high mineral content and phenolic compounds will provide an alternative for healthy food, especially during a pandemic virus recently. Besides this, the foodstuffs can be utilized to broad market opportunities and decrease a need of imports.
