Proteomics integrated with metabolomics: Analysis of the internal mechanism underlying changes in meat quality in different muscles from bactrian camels.

Knowledge about the quality of meat obtained from different muscles is crucial for developing high-quality camel meat for commercial use. Metabolomic and proteomic profiles of the longissimus thoracic (LT), semitendinosus (ST), and psoas major (PM) muscles of the bactrian camel, which significantly vary in aspects such as intramuscular fat (IMF) content and shear force, were comprehensively compared to evaluate the impact of these changes on meat quality. Compared with ST and PM muscles, LT muscles had higher IMF content, were more tender, and had a lower shear force.

Automated and explainable machine learning for monitoring lipid and protein oxidative damage in mutton using hyperspectral imaging.

Current detection methods for lipid and protein oxidation using hyperspectral imaging (HSI) in conjunction with machine learning (ML) necessitate the involvement of data scientists and domain experts to adjust the model architecture and tune hyperparameters. Additionally, prediction models lack explainability in the predictive outcomes and decision-making process. In this study, ML, automated machine learning (AutoML) and automated deep learning (AutoDL) models were developed for visible near-infrared HSI of mutton samples treated with different freeze-thaw cycles to evaluate the feasibility of building prediction models for lipid and protein oxidation without manual intervention.

Preparation of poly(l-lactic acid) antibacterial film based on surface grafting of modified chitosan and its preservation effect on chilled beef.

Chilled beef is a perishable food product. Due to the broad-spectrum antimicrobial properties of chitosan, and the biodegradability of PLLA, chitosan and PLLA are introduced double bonding groups to obtain Chitosan-graft-Glycidyl methacrylate (Cs-g-GMA) and Poly(L-lactic acid)-co-poly(butylene itaconate) (PLBI), respectively. Cs-g-GMA is then grafted onto the surface of PLBI films by UV curing to produce PLBI/Cs-g-GMA films with non-migratory, broad-spectrum antimicrobial, biodegradable, and possess good oxygen barrier properties, compared to current antimicrobial films.
