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.

作者： Wenjie Wang Lijun Shao Xiao Jiang Qiulu Chu Jian Xiao Shufang Wu College of Light Industry and food Engineering， Nanjing forestry university department of forest Biomaterials， North Carolina State university Jiangsu Co-Innovation Center of Efficient Processing and Utilization of forest Resources， Nanjing forestry university

Atopic dermatitis (AD) is a common multifactorial skin disease characterized by chronic inflammation， unbearable itching， and significant physical and mental burden on patients. In recent years， there has been extensive studied on the use of natural polysaccharides in anti-inflammatory therapy， due to their low toxicity and multi-target pharmacological activity. The unique biological activities of polysaccharides from natural sources as functional food additives and cosmeceuticals present a new option for the treatment of AD. This review aims to summarize the pathogenesis of AD， the therapeutic effects， and the mechanisms of natural polysaccharides， as well as discuss the limitations and prospects of these compounds in the treatment of AD. The insights provided in this review can serve as references and inspiration for the development of applications of natural polysaccharides in the treatment of AD.

Postbiotics from Saccharomyces cerevisiae fermentation stabilize microbiota in rumen liquid digesta during grain-based subacute ruminal acidosis(SARA) in lactating dairy cows

Background Subacute ruminal acidosis(SARA) is a common metabolic disorder of high yielding dairy cows, and it is associated with dysbiosis of the rumen and gut microbiome and host inflammation. This study evaluated the impact of two postbiotics from Saccharomyces cerevisiae fermentation products(SCFP) on rumen liquid associated microbiota of lactating dairy cows subjected to repeated grain-based SARA challenges. A total of 32 rumen cannulated cows were randomly assigned to 4 treatments from 4 weeks before until 12 weeks after parturition. Treatment groups included a Control diet or diets supplemented with postbiotics(SCFPa, 14 g/d Original XPC; SCFPb-1X, 19 g/d Nutri Tek; SCFPb-2X, 38 g/d Nutri Tek, Diamond V, Cedar Rapids, IA, USA). Grain-based SARA challenges were conducted during week 5(SARA1) and week 8(SARA2) after parturition by replacing 20% DM of the base total mixed ration(TMR) with pellets containing 50% ground barley and 50% ground wheat. Total DNA from rumen liquid samples was subjected to V3–V4 16S r RNA gene amplicon sequencing. Characteristics of rumen microbiota were compared among treatments and SARA *** Both SARA challenges reduced the diversity and richness of rumen liquid microbiota, altered the overall composition(β-diversity), and its predicted functionality including carbohydrates and amino acids metabolic pathways. The SARA challenges also reduced the number of significant associations among different taxa, number of hub taxa and their composition in the microbial co-occurrence networks. Supplementation with SCFP postbiotics, in particular SCFPb-2X, enhanced the robustness of the rumen microbiota. The SCFP supplemented cows had less fluctuation in relative abundances of community members when exposed to SARA challenges. The SCFP supplementation promoted the populations of lactate utilizing and fibrolytic bacteria, including members of Ruminococcaceae and Lachnospiraceae, and also increased the numbers of hub taxa during non-SARA an
