Effects of hydrothermal treatment and low-temperature storage of whole wheat grains on in vitro starch hydrolysis and flour properties.

This study evaluated the effect of hydrothermal treatment of whole wheat grains at 100 °C followed by cold-storage (4 °C/ 7 days) on the resulting grains, flakes, and flour characteristics. The extent of starch hydrolysis after oral-gastro-small intestinal digestion in vitro was significantly lower (p < 0.05) in intact grains, flakes, and flours from the cold-stored grains, 35.

Effects of Xanthan Gum, Lambda-Carrageenan and Psyllium Husk on the Physical Characteristics and Glycaemic Potency of White Bread.

White bread contains a high proportion of easily digestible starch, which contributes to an undesirable rapid increase in blood glucose concentration. This study investigated the effects of nonstarch polysaccharides (NSP) -xanthan gum, lambda-carrageenan and psyllium husk on the physical functionality and glycaemic potency of white bread. The amount of water for each formulation was adjusted based on DoughLab set at a target torque value of ~500 FU for sufficient dough development.

Glycaemic potency reduction by coarse grain structure in breads is largely eliminated during normal ingestion.

The hypothesis that coarse grain particles in breads reduce glycaemic response only if the particles remain intact during ingestion was tested. Three breads were formulated: (1) White bread (WB - reference), (2) 75 % of kibbled purple wheat in 25 % white bread matrix (PB) and (3) a 1:1 mixture of 37·5 % kibbled soya beans and 37·5 % of kibble purple wheat in 25 % white bread matrix (SPB). Each bread was ingested in three forms: unchewed (U), as customarily consumed (C) and homogenised (H).

Meat analogs: Protein restructuring during thermomechanical processing.

Increasing awareness of inefficient meat production and its future impact on global food security has led the food industry to look for a sustainable approach. Meat products have superior sensorial perception, because of their molecular composition and fibrous structure. Current understanding in the science of food structuring has enabled the utilization of alternative or nonmeat protein ingredients to create novel structured matrices that could resemble the textural functionality of real meat.

Effects of Maillard-reacted beef bone hydrolysate on the physicochemical properties of extruded meat alternatives.

Meat analogues are made from plant proteins using high-moisture extrusion processing, to have the same textural and structural properties as meat. However, meat analogues exhibit very weak aroma and are almost tasteless, which has resulted in limited market success. Maillard-reacted beef bone hydrolysate (MRP) provides important sensory aspects of heat-treated food products, by contributing to their appearance, texture, flavor, and aroma.
