Summary: The effect of the addition of pregelatinized rice starch paste (PRSP) on the retrogradation of rice starch (RS) gels was studied. It was found that adding PRSP decreased the storage modulus of RS gels after short-term storage. XRD analysis revealed that the retrogradation degree of RS gels with PRSP was lower, indicating that PRSP could restrain the long-term retrogradation of rice starch.

Summary: This study investigates the correlation between starch internal structure and thermal properties in different potato varieties. It finds that the distribution and composition of internal chains and building blocks in starch play a role in the gelatinisation and retrogradation processes. Potato varieties with a high content of amylopectin have higher gelatinisation temperatures, while dense structures of amylopectin favor retrogradation.

Summary: This study investigates the influence of rice protein on the gelatinization and retrogradation of rice starch during storage. The addition of rice protein decreases viscosity and gelatinization enthalpy, while increasing gelatinization temperature. It also reduces gel hardness, retrogradation enthalpy, and crystallization rate constant, but increases Avrami exponent during retrogradation. Additionally, rice protein improves water molecule mobility, weakens the conversion from bound water to free water in gels, and moderately enhances gel shape uniformity and thickness. However, excessive protein addition leads to the formation of disulfide bonds, which enhance gel strength and network structure but reduce the protein's ability to facilitate water molecule mobility and restrict water migration, ultimately reducing its anti-retrogradation capability.

Summary: Bread dough and bread are complex systems influenced by the interaction between starch polymers, flour components, and added ingredients. Starch, along with gluten proteins, plays a crucial role in determining the quality characteristics of the final baked product. Wheat starch, consisting of amylose and amylopectin, is organized in granules and interacts with various components during the breadmaking process. Understanding the starch structure-function relationship and the factors affecting it during dough formation, fermentation, baking, cooling, and storage is essential for comprehending the textural perception of bread.

Summary: Differences in starch digestibility among different high amylose rice cultivars are mainly attributed to the enzymolysis resistance and high gelatinization temperature (GT) of starch granules. Resistant starch content is positively correlated with intermediate chain amylopectin (DP 13-24) content and negatively correlated with short chain amylopectin (DP 6-12) content. Moreover, under normal cooking conditions, some starch granules do not fully gelatinize due to the high GT of the starch, resulting in lower starch digestibility.

Summary: Whole white rice is an important staple food, and its starch digestion rate and location in the gastrointestinal tract play a crucial role in human health. The structure of starch undergoes order-disorder transitions during cooking, which determines its digestibility. The length distributions of amylose and amylopectin chains influence the gelatinization properties of rice starch. The chain-length and molecular-size distributions of starch affect nucleation, crystal growth rates, and interactions during retrogradation. Various kinetics models have been developed to study starch digestibility, providing new insights into the structural basis of cooked whole rice. Different digestible fractions of starch with distinct digestion patterns have been discovered, and their kinetics are largely determined by fine molecular structures. This review summarizes current insights and future directions for understanding starch digestibility in whole cooked rice, with the aim of developing a healthier rice with slower starch digestibility.

Summary: This study introduces a new synthetic-jet actuator, called ultrasonic-driven synthetic-jet (USDSJ) actuator, which consists of a fixed flat plate and a vibrating flat surface driven by an ultrasonic transducer. The jet created by the actuator is visualized using the schlieren method and it is found that a pulsed jet is created at a high frequency of 19.7 kHz. The estimated jet velocity reaches 150 m/s and is linearly proportional to the vibrating-surface amplitude normalized by the height of the gap.

Summary: The content of resistant starch (RS) is positively correlated with the apparent amylose content (AAC). We analyzed two Indica rice mutants with high AAC and found that their RS content differed remarkably. The difference in RS content may be attributed to the differences in fine structures of amylopectin.

Summary: Liver disease is a major cause of global mortality, and identifying biomarkers for diagnosing its progression is crucial for improving outcomes. Targeted mass spectrometry is a powerful tool for verifying biomarker candidates and clinical applications, particularly for glycoproteins translation. However, the limitation of analyzing only one sample per run has become apparent. In this study, a high-throughput intact N-glycopeptides quantification strategy was developed, allowing the validation of 20 samples per run with an average analysis time of 3 minutes per sample. The strategy was applied in a cohort of 461 serum samples and identified a panel of 10 IgG N-glycopeptides that have strong clinical utility in evaluating the severity of liver disease.
