Modulating chestnut starch digestibility by heat–moisture synergistic recrystallization treatment: from condition optimization, physical properties to structural aspects

HMRT was proven to be an effective strategy for increasing starch resistance. In this study, the crystallinity and orderability of starch were enhanced after HMRT. Furthermore, decreased starch hydration was shown to impede enzymatic digestion. The research sheds new light on the rational design of anti-digestive starch-based food systems with tailored properties. © 2026 Society of Chemical Industry.
