Evaluation of in vitro digestion methods and starch structure components as determinants for predicting the glycemic index of rice

Mainstreaming the low glycemic index (GI) trait in breeding programs is constrained by low-throughput and high-cost clinical GI phenotyping. This study aimed to evaluate the potential of starch fine structure components and simulated digestion parameters in predicting GI in rice. Amylose (AM1 and AM...

Summary:Mainstreaming the low glycemic index (GI) trait in breeding programs is constrained by low-throughput and high-cost clinical GI phenotyping. This study aimed to evaluate the potential of starch fine structure components and simulated digestion parameters in predicting GI in rice.
