Food and Machinery
In this study, color, cooking loss, water holding capacity, water-loss rate, pH value, amino acid and fatty acid composition of raw meat were investigated during storage （0, 1, 2, 4, 8 weeks） at -18 ℃. The results indicated that water-loss rate and cooking loss of meat increased as the storage time increased, and water holding capacity of meat decreased with the increasing storage time （P<0.05）. The contents of lysine, alanine and cysteine increased with the increasing storage time. The amounts of saturated fatty acids increased obviously, while polyunsaturated fatty acids contents decreased with the increasing storage time. Therefore, although frozen storage is an ideal method for meat storage. However, the nutritive value of raw meat will change, leading to the decline of meat quality.

Asgardarchaeota have been proposed as the closest living relatives to eukaryotes, and a total of 72 metagenome-assembled genomes (MAGs) representing six primary lineages in this archaeal phylum have thus far been described. These organisms are predicted to be fermentative heterotrophs contributing to carbon cycling in sediment ecosystems. Here, we double the genomic catalogue of Asgardarchaeota by obtaining 71 MAGs from a range of habitats around the globe, including the deep subsurface, brackish shallow lakes, and geothermal spring sediments. Phylogenomic inferences followed by taxonomic rank normalisation confirmed previously established Asgardarchaeota classes and revealed four additional lineages, two of which were consistently …

Journal of Food and Drug Analysis
This study aims to clarify the effects of chicken liver hydrolysates (CLHs) on long-term high-fat diet (HFD)-induced insulin resistance (IR) and hepatosteatosis in mice. In vitro, the 400 mM oleic acid (OA)-added medium successfully stimulated the cellular steatosis on FL83B cells, and the cellular steatosis was attenuated ( p < 0.05) by supplementing with CLHs (4 mg/L). In vivo, the effects of CLHs on IR and hepatosteatosis development were tested in 20-week HFD-fed mice. HFD-induced increases in final body weight, but body weight gains of mice were decreased ( p < 0.05) by supplementing CLHs. Elevated ( p < 0.05) serum aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), free fatty acids (FFAs), triglyceride (TG), total cholesterol (TC), and fasted glucose values in HFD-fed mice decreased ( p < 0.05) by supplementing CLHs. Both results of hepatic steatosis and fibrotic scores also indicated the retardation ( p < 0.05) of the hepatosteatosis in cotreated groups. Moreover, the CLH supplementation sustained ( p < 0.05) hepatic and peripheral insulin signal sensitivity in HFD-fed mice. CLH supplementation could ameliorate hepatic lipid deposition, hepatic/peripheral IR in a long-term high-fat dietary habit, and also improve the universal glucose homeostasis by upregulating hepatic and peripheral insulin sensitivities.
