Abstract: Rice bran, a common byproduct during of the rice milling process, is rich in unsaturated fats, proteins, crude fiber, vitamins, and various bioactive components. However, the stability of fresh rice bran is poor, and it is highly susceptible to rancidity and deterioration, largely limiting the comprehensive and efficient utilization of rice bran. In recent years, researchers have conducted extensive studies on non-thermal stabilization techniques for rice bran and have achieved significant results. Based on this, this paper provides an overview of the nutritional composition and rancidity mechanism of rice bran and various non-thermal techniques for its stabilizationologies, aiming to provide references for the vigorous development of rice bran resources and the improvement of rice bran utilization efficiency.

Key words: rice bran, hydrolysis reaction, oxidation reaction, non-thermal stabilization techniques
