Evaluation of moisture migration and microstructure of quick-frozen wet rice flour after freeze-thaw cycles and changes in texture, cooking, and sensory properties.

This study investigated the quality changes of quick-frozen wet rice flour before and after freeze-thaw cycles. As the freeze-thaw cycle was prolonged, the water mobility of quick-frozen wet rice flour decreased and the pore size and porosity of the microstructure increased. As a result, the hardness, cooking loss, water absorption, and water precipitation of the rice flour increased, while the sensory score and viscosity decreased.

The possibility of the computer simulation-assisted IDDSI framework for the development of thickened brown rice paste.

Increasing requests for thickened fluid food are demanded with population aging, while the limited information provided by the International Dysphagia Diet Standardisation Initiative (IDDSI) is insufficient for food development. Recently, the introduction of computer simulation seems to be able to overcome this dilemma. Here, a thickened fluid system (xanthan gum and konjac glucomannan, XG and KGM) at different ratios was kept at the same IDDSI level 3.

Prolonging heat-moisture treatment time at medium moisture content optimizes the quality attributes of cooked brown rice through starch structural alteration.

Structural features of rice starch-protein system: Influence of retrogradation time and quick-freezing temperature.

This work investigated the effect of retrogradation time (0 h, 2 h, 4 h, 6 h, 8 h) and freezing temperature (-20 °C, -32 °C, -80 °C) on the muti-scale structures of the rice starch-protein system of quick-frozen wet rice noodles. The Relative crystallinity and porosity of the rice starch-protein system increased with increasing retrogradation time. However, while longer retrogradation does lead to an improvement in relative crystallinity, it also results in significant damage to the microstructure.

Effect of the Combined Ultrasound with Other Technologies on Food Allergenicity: Ultrasound before, under, and after Other Technologies.

Food allergies are a main public health disease in the world. Ultrasound is an environmentally friendly technology that typically leads to protein unfolding and loss of protein structure, which means it has the potential to be combined with other technologies to achieve a great reduction of allergenicity in foods. This review concludes the effects of the combined ultrasound with other technologies on food allergenicity from three combinations: ultrasound before other technologies, ultrasound under other technologies, and ultrasound after other technologies.
