Abstract: To analyze the adaptability of glutinous rice flour to the fresh Mochi making, the total starch, amylose, crude protein, crude fat, ash and damaged starch content of 10 glutinous rice flour samples were determined, and the production of fresh Mochi was carried out under laboratory conditions, the sensory evaluation and texture analyzer were used to detect the eating quality and aging property of fresh Mochi.The mochi samples and glutinous rice flour were evaluated and divided into different grades based on system clustering analysis; the influence of glutinous rice flour characteristics on fresh Mochi quality was investigated by correlation analysis.The results showed that the main characteristics of texture properties during the aging process of fresh Mochi were the significant increase of hardness, chewiness, and the gradual reduction of cohesiveness and resilience.And the anti-aging ability of Mochi made by japonica glutinous rice flour was better than those by indica glutinous rice flour.The glutinous rice flour was divided into 2 grades with the aging rate as the evaluation index, of which JF1, JF2, JF3, IF1, IF2 and BM1 glutinous rice flour was suitable for the production of fresh Mochi, while IM1-IM4 glutinous rice flour was not suitable.And the glutinous rice flour was divided into 3 grades with the comprehensive value of sensory and texture properties as the evaluation indexes, of which JF2, JF3, IF1, IF2, IM3 and IM4 glutinous rice flour was most suitable for the production of fresh Mochi, second was JF1, IM1 and BM1 glutinous rice flour, while IM2 glutinous rice flour was not suitable.The quality of fresh Mochi was mainly influenced by starch and protein components in glutinous rice flour.And the amylose and protein could accelerate the aging and reduce the palatability of Mochi.Therefore, the glutinous rice varieties with low amylose and low protein content were more suitable for Mochi.And the moderate amounts of damaged starch in glutinous rice flour were beneficial to the improvement of Mochi texture property.
