Progressive study of the effect of superfine green tea, soluble tea, and tea polyphenols on the physico-chemical and structural properties of wheat gluten in noodle system.

In this study, the improving effects of green tea powder, soluble tea, and tea polyphenols on the mixing and tensile qualities of dough and texture of tea-enriched noodles, as well as the physico-chemical and structural properties of gluten proteins were progressively investigated. Dough strength and noodle texture were significantly increased by all the three tea products. Tea polyphenols in particular presented the most effective improvement with highest dough stability, resistance, and noodle chewiness.

Inhibiting effect of low-molecular weight polyols on the physico-chemical and structural deteriorations of gluten protein during storage of fresh noodles.

In this study, the inhibiting effects of low-molecular weight polyols on the deterioration of gluten network and noodle texture were systematically investigated, based on dough rheological properties, and the macroscopic, structural and water status changes of gluten protein during storage of fresh noodles. Both glycerol and propylene glycol significantly restrained the decrease of GMP gel weight, LA-SRC value, hardness and springiness, and the increase of cooking loss. SEM showed that polyols retarded the collapse of gluten network, with still continuous gluten fibrils.

Comparative study of the quality characteristics of fresh noodles with regular salt and alkali and the underlying mechanisms.

The quality properties of fresh noodles with NaCl and alkali were characterized by rheological, cooking, and texture properties. Microstructure, starch viscosity, protein conformation, gelatinization and protein polymerization during cooking, and water status were determined to investigate the mechanisms underlying their quality differences. The results showed that alkali induced more significantly increased (P < .
