Webb31 juli 2024 · Starch–gluten interactions are affected by biopolymer type and processing. However, the differentiation mechanisms for gluten–starch interactions during heating have not been illuminated. The effects of glutens from two different wheat flours (a weak-gluten (Yangmai 22, Y22) and a medium-strong gluten (Yangmai 16, Y16)) on … WebbA crystal is a form of solid substance in which constituents—such as atoms, molecules, or ions—are arranged sterically in regularly repeating patterns, forming a space lattice. The arrangement of atoms in a crystal is called a crystal structure and the minimum unit in a regularly repeating pattern is called a unit cell.
