This study investigated the effects of combining sous vide (SV) and high-pressure (HP, 0.1-200 MPa) on the structural changes of meat proteins and the eating quality of pork loin in comparison to commercial cooking (CC). Differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) spectroscopy showed that SV under HP stabilized the secondary structure of sarcoplasmic proteins. SV under HP treatments significantly reduced cooking loss and improved water-retention ability. Texture profile analysis (TPA) showed that SV under HP reduced the hardness and chewiness while increasing springiness. Instrumental color analysis revealed that SV under 200 MPa resulted in higher L* and a* values with a lower b* value than SV-AT (p < 0.05). These findings demonstrated that SV cooking under HP was a promising cooking method for enhancing the eating quality of pork loin, potentially expanding the utilization of lean cuts, which are generally less favored by consumers.

Proteins, as typical macromolecules in aquatic products, have been demonstrated to play a crucial role in flavor release. The structural modifications of water-soluble proteins (WSP), salt-soluble proteins (SSP), and alkali-soluble proteins (ALSP) in oysters after Sous Vide (SV) heating, along with their interactions with flavor compounds, were systematically investigated. More significant alterations in secondary and tertiary structures in SSP were observed compared to WSP and ALSP following SV heating, accompanied by the highest degree of hydrophobicity and aggregation.

This study investigates Bimi ( Italica × Alboglabra), a hybrid between kailan and conventional broccoli, to evaluate its compositional, functional, and sensory properties in relation to industrial sous-vide processing and refrigerated storage. Proximate composition, amino acid and fatty acid profiles, and mineral content were determined in raw samples. Color, chlorophyll content, total polyphenols, and antioxidant capacity (FRAP, ABTS, DPPH) were analyzed before and after sous-vide treatment and following 60 days of storage.

Tibetan pork is a local Chinese pig breed that is raised in high-altitude environments. This study examined the formation pathways of lipid-derived odour-active volatile compounds in Tibetan pork across three cooking methods: sous-vide (SV), pan-frying (PF), and oven-roasting (OR), by investigating the pro-oxidative roles of free iron and changes of lipid molecules. It was found that lipid-derived volatiles in low-temperature methods were generated in two stages: initially from free fatty acids and lysophosphatidylcholines, and later from the oxidation of phospholipids, with the later stage being affected by free iron, which followed by increasing lipid oxidation properties.

The aim of this study was to evaluate the effect of marinade type and marinating time on the physicochemical and sensory properties of pork tenderloin cooked using low-temperature, vacuum-sealed cooking. The study included marinades based on pineapple juice, red wine, kefir and a mixture of dried herbs. The assessment of the effect of marinades was based on the analysis of the color, texture, chemical composition and organoleptic properties of the meat after cooking using the sous vide method.
