Convenience rice has become widely popular due to its easy availability for cooking. This study investigated the starch structure and composition of leachate and the microstructure of reheated convenience rice using novel processing technologies: super-heated steaming(SHS), auto-electric cooking(AEC), and pressurized-steam cooking(PSC). Additionally, the effect of two different target water contents(58% and 63%) was also evaluated. The PSC_63% sample had the highest total solids and amylopectin amount in the leachate. The amylopectin amount in the leachate differed significantly based on the targeted water content. Morphological characterization revealed that the swelling of starch and the coated layer on the surface of rice grains were most pronounced in the PSC_63% sample due to the pressure processing. The textural hardness of the AEC_58% sample was much higher than that of the other samples. The PSC_63% sample had the highest textural adhesiveness value, which can be attributed to the highest amylopectin amount in the leachate. Sensory characterization showed that the PSC_63% sample had the highest glossiness, whiteness, moistness, and overall acceptability. The principal component analysis score plots presented substantial differences in the leachate and textural and sensory characteristics of reheated convenience rice among the different processing technologies.

Heat processing of food has been well validated as the trigger to generate heat-processing side product of advanced lipoxidation end products (ALEs)， which potentially engenders the threat on systemic health or progression of diseases， especially the accumulated effect after long-term intake. Thus， the study was proposed to evaluate the effect of dietary ALEs on health after long-term ingestion， specifically through simulating the intake of dietary ALE in mice within 9 months to investigate the intervention effect and underlying mechanism. The unexpected observation of renal insufficiency or impairment after long-term intake of dietary ALEs indicated the negative impact on renal health， which has been verified by the pathological analysis. Further studies revealed that a high-ALEs diet disrupted the intestinal barrier， with enhanced impact after disturbing the gut microbiota to potentially lower the abundance of beneficial microbiome through producing nephrotoxic metabolites. Correlation analysis showed that the proliferation of harmful bacteria and the reduction of beneficial bacteria were strongly correlated with intestinal barrier damage and the development of renal insufficiency. Furthermore， the underlying mechanism was unveiled as that ALEs could inhibit AMPK/SIRT1 signaling to fundamentally induce renal inflammation and oxidative stress. Thus， it was revealed that long-term intake of dietary ALE could result in renal impairment， and the results emphasized the control or intervention on dietary ALE to decrease to accumulated impairment on systemic health.

Digestive health is important for overall well-being， but gut health problems are common in the Chinese population. The objective of this study was to investigate the effects of oat β-glucan–based prebiotic blended formulas in humans on digestive health by assessing defecation frequen-cy， defecation symptoms， stool quality， self-reported digestive feelings， defecation satisfaction， and gut bacteria. A parallel， randomized， double-blind， controlled trial was conducted in 168 eli-gible adults randomized to three groups for 14 days: Intervention Groups A and B received two different doses of oat β-glucan–based prebiotic blended formulas and a Control Group received oat β-glucan mixed with hydroxypropylmethyl-cellulose and microcrystalline cellulose. Partici-pants completed a defecation diary and Bristol stool chart daily and digestive system question-naires weekly. Fecal samples were collected on Day 0 and Day 14 to evaluate gut bacteria using 16S rDNA analysis. Both formulas improved defecation frequency， stool quality， defecation symptoms， defecation satisfaction， and on digestive health of human， compared with baseline (P health in generally healthy Chinese adults. These formulas are a feasible nutritional strategy for digestive health.
