Moisture Sorption Isotherms of Polydextrose and Its Gelling Efficiency in Inhibiting the Retrogradation of Rice Starch.

As an anti-staling agent in bread, the desorption isotherm of polydextrose has not been studied due to a very long equilibrium time. The adsorption and desorption isotherms of five Chinese polydextrose products were measured in the range of 0.1-0.

Effect of Intermittent Low-Pressure Radiofrequency Helium Cold Plasma Treatments on Rice Gelatinization, Fatty Acid, and Hygroscopicity.

To establish the safe and reproducible effects of cold plasma (CP) technology on food products, this study evaluated the gelatinization parameters, fatty acid profile, and hygroscopic properties of rice grains repeatedly treated with low-pressure radiofrequency (RF) helium CP (13.56 MHz, 140 Pa, 120 W-20s, 0-4 times, and 300 g sample). Compared with the untreated (zero times) sample, with an increase in CP treatment times from one to four on rice, the water contact angle and cooking time decreased, while the water absorption rate and freshness index increased, and the pH value remained unchanged.

Controlled atmosphere storage drive proteomic change in Chinese Daohuaxiang.

Although the use of a controlled atmosphere is one of the most successful storage techniques, the mechanism thereof in rice storage remains unclear. We stored aromatic rice cultivar Daohuaxiang in a package filled with 98 % N and 35 % CO for 3 months. We investigated 2-acetyl-1-pyrroline loss, enzyme activities, and proteomics changes of rice during storage.

Life Histories and Functional Responses of Two Predatory Mites Feeding on the Stored-Grain Pest Badonnel (Psocoptera: Liposcelididae).

Oudemans and (Schrank) are predators of stored-grain pests in China. The psocid Badonnel is prone to outbreaks in depots. To assess the potential of large-scale breeding with Linnaeus and the biological control potential of and against , we determined the development times of different stages at 16, 20, 24, and 28 °C and 75% relative humidity (RH) while feeding on as well as the functional responses of both species' protonymphs and females to eggs at 28 °C and 75% RH.

Ligand-binding specificities of four odorant-binding proteins in Conogethes punctiferalis.

Odorant-binding proteins (OBPs) play essential roles in lepidopteran insects' perception of host volatiles by binding and transporting hydrophobic ligands. The yellow peach moth (YPM), Conogethes punctiferalis (Guenée), is a serious agricultural pest, with broad host range and cryptic feeding habits. However, few studies about YPM perceiving pheromones and host plant odorants have been reported.
