This study investigates the combined effects of extrusion processing and bamboo leaf flavonoids (BLFs) on the digestive properties and multiscale structure of maize starch (MS). Extrusion increased the levels of rapidly digestible starch (RDS) and slowly digestible starch while the content of resistant starch (RS) decreased to 20.19 %. Notably, higher BLF concentrations reversed this trend, increasing RS content to 35.30 %. The four main BLF monomers inhibited α-amylase activity by forming hydrogen bonds and hydrophobic interactions with its active residues. Extrusion disrupted the layered structure of MS, reducing its compactness, while the addition of 2.5 % BLFs led to pore formation on starch surface. The relative crystallinity of the starch decreased by approximately 34.34 % after extrusion. The addition of BLFs increased the single helix structures and improved the relative crystallinity of the nanocrystals with orthorhombic crystal structure. These results provide critical insights into how extrusion combined with BLFs can regulate starch digestibility.

Abstract: The rapid development of wearable electronics necessitates the advancement of strain sensors with both high sensitivity and stretchability for diverse applications, such as health monitoring and human-computer interaction.This study presents a highly sensitive and stretchable strain sensor fabricated through the synergistic integration of nested wrinkle-crack microstructures.The sensor is composed of a waterborne polyurethane film loaded with gold, featuring nested wrinkle structures.These structures are achieved by transferring wrinkles from a pre-fabricated polydimethylsiloxane template and further inducing compressive stress during magnetron sputtering.This design gives the sensor a large gauge factor of up to 7805.9, a stretchability of 60% strain range, and stability over 1000 stretch-release cycles.The sensor demonstrated its potential to monitor subtle physiol. signals such as facial expressions, pulse, and voice recognition.This work provides important insights for the development of high-performance wearable electronic devices for smart health monitoring.Graphical Abstract:
