The storage period of paddy is a critical factor affecting rice quality, and it is still unclear how fresh rice noodles, primarily made from paddy, respond to changes in the storage period. To elucidate the relationship between the paddy storage period and the quality of fresh rice noodles, this study used fourteen rice varieties as materials and set up three paddy storage periods (six months, nine months, and twelve months). It explored the quality variation patterns of fresh rice noodles processed from these paddies and analyzed the relationship between the two in conjunction with rice quality. The results indicated that fresh rice noodles produced from paddies stored for nine months exhibited superior quality compared to the other two storage periods. Grey relational analysis and correlation analysis confirmed that this was primarily attributed to changes in the gel consistency of the paddy. When the paddy was stored for nine months and the rice gel consistency was approximately 32 mm, the quality of the fresh rice noodles produced was optimal, serving as an important basis for selecting raw materials for fresh rice noodles.
稻谷的储存期是影响大米品质的关键因素，而以稻谷为主要原料的鲜米粉如何响应储存期的变化仍不明确。为阐明稻谷储存期与鲜米粉品质之间的关系，本研究以14个水稻品种为材料，设置了三个稻谷储存期（6个月、9个月和12个月）。探究了由这些稻谷加工而成的鲜米粉的品质变化规律，并结合大米品质分析了二者之间的关系。结果表明，储存9个月的稻谷制成的鲜米粉品质优于其他两个储存期。灰色关联分析和相关性分析证实，这主要归因于稻谷胶稠度的变化。当稻谷储存9个月且大米胶稠度约为32毫米时，所制得的鲜米粉品质最佳，可为鲜米粉原料选择提供重要依据。
