New insights into how freeze-drying and cryo-milling affects the fine structure and digestibility of gelatinized starch.

Freeze-drying (FD) and cryo-milling (CM) are common methods for preparing powder gelatinized starch samples. This study investigates the structural characterization of raw/gelatinized maize starches and digestibility after FD/CM processes to elucidate their effect on starch digestibility determination. Results showed that FD slightly increased digestibility, while higher initial glucose content in CM samples, especially for gelatinized samples.

Effects of frozen storage on the quality characteristics of frozen whole buckwheat extruded noodles.

The effects of frozen storage (-18 °C, 180 days) on the quality of frozen whole buckwheat extruded noodles (FWBEN) were investigated. The water content of FWBEN decreased, while the reheating time, water absorption, and dry consumption rate increased with prolonged storage time. Cooking loss increased from 3.

Toward a comprehensive understanding of various milling methods on the physicochemical properties of highland barley flours and eating quality of corresponding sugar-free cookies.

Highland barley (HB) was subjected to dry-, semidry-, wet-milling methods and assessed for flour physicochemical properties and eating quality of corresponding sugar-free cookies. Results showed that there were significant differences between different milled flours in damaged starch content, particle size, hydration, pasting properties, and color. High a* values and poor hydration/pasting properties of wet-milled flours were associated with its smallest particle size and lowest content of damaged starch (25.

Gallic acid-fortified buckwheat Wantuo: characteristics of in vitro starch digestibility, antioxidant and eating quality.

Unlabelled: Gallic acid (GA), presented in various plant sources, is increasingly used as a nutritional food ingredient due to its prominent bioactive. In this work, common buckwheat Wantuo (BWT, a Chinese traditional starch gel food) was fortified with 1,3,5% (w/w) GA and assessed for physicochemical properties of flour as well as in vitro starch digestibility, antioxidant and eating quality of BWT. The results clearly showed that the hydration, pasting properties as well as gel microstructure and texture of gel were influenced with addition of GA, while the color of flours showed no significantly change.
