Building in vitro starch hydrolysis models to predict the nutritional traits of phosphorus-fertilized grain starches
- Beschreibung
Phosphorus is a macro-nutrient widely participating starch biosynthesis, the building of starch molecular structure, physicochemical and functional properties (Zhang et al., 2021, 2023). Phosphorus availability has significant effects on amylose/amylopectin ratio, starch granule size distribution, and viscosity (Ni et al., 2012; Li et al., 2019). Among them, amylose content is the most important factor to influence the starch digestion. Higher starch digestion rate accelerates the rapid increase of blood glucose after meal, which is the culprit to cause diabetes type II. Therefore, the current project aims to build in vitro starch digestion models to predict the nutritional traits of maize starches under different phosphorus fertilization.
