Summary: The study showed that ice structuring protein (ISP) significantly inhibits the quality deterioration of quick-frozen pork patties subjected to multiple freeze-thaw cycles, including improvements in hardness and springiness, reduction in thawing loss, inhibition of moisture migration, and protection of microstructure. Additionally, ISP also helps in lowering levels of harmful substances in the patties, indicating its potential benefits in meat products.

Summary: This study aimed to investigate myofibrillar protein denaturation induced by pH changes during freeze-thaw cycles and propose a mitigation strategy. The findings showed that as the number of freeze-thaw cycles increased, protein molecules unfolded and formed larger aggregates, leading to structural integrity disruption. Addition of cellobiose could effectively inhibit pH changes and minimize freeze-thaw damage to myofibrillar protein, making it a potential new cryoprotectant.

Summary: The properties of chitosan ice coating and its inhibitory effect on the quality deterioration of quick-frozen fish balls during repeated freeze-thaw cycles were studied. Increase in chitosan concentration led to higher viscosity and ice coating rate, while lower water vapor permeability, water solubility, and transmittance. 1.5% chitosan was found to be the optimal coating for freeze-thaw quick-frozen fish balls. Total volatile base nitrogen (TVB-N) values, frost production, and free water content increased significantly with an increase in freeze-thaw cycles, while whiteness values, textural properties, and water-holding capacity (WHC) decreased. The chitosan ice coating effectively reduced water loss, ice crystallization and recrystallization, and pores of the samples, thereby inhibiting the quality deterioration.

Summary: This study explored the cryoprotective effect of ice structuring protein (ISP) on myofibrillar protein (MP) in frozen pork patties, revealing that ISP improved the aggregation behavior and structural stability of MP. Addition of ISP resulted in a more stable MP aggregation system with uniform particle size distribution and higher zeta potential. ISP treated patties showed decreased surface roughness and carbonyl content of MP, increased free amino content, and improved secondary and tertiary structure stability. Overall, ISP has the potential to enhance MP aggregation and structural stability during frozen storage.

Summary: The effect of carboxymethyl chitosan (CMCH) on the oxidation stability and gel properties of myofibrillar protein (MP) from frozen pork patties was investigated. CMCH effectively inhibited the denaturation of MP induced by freezing, improving the protein solubility and reducing carbonyl content, loss of sulfhydryl groups, and surface hydrophobicity. Additionally, CMCH enhanced water mobility, reduced water loss, and improved the whiteness, strength, and water-holding capacity of MP gels. It also stabilized the micro-structure of the gel and maintained its relative integrity.

Summary: In this study, the effects of calcium chloride (CaCl2) addition on the physical and oxidative stabilities of filled hydrogel were investigated. The results showed that the addition of CaCl2 significantly enhanced the physical properties and viscosity of the hydrogels, while reducing their lightness and whiteness values. The appropriate levels of CaCl2 also improved the oxidative stability of the filled hydrogels, but higher levels resulted in negative effects.

Summary: The effects of different yeast strains on the taste and odour profiles of reduced-salt dry sausages were investigated. Inoculation of specific yeast strains compensated for the lack of saltiness and umami tastes and resulted in an odour profile similar to traditional dry sausages. Volatile analysis showed higher levels of certain compounds in the inoculated sausages. Sensory evaluation confirmed the positive contribution of the yeast strains to the aroma and saltiness of reduced-salt dry sausages. Overall, P. kudriavzevii and D. hansenii can be used as effective starter cultures to improve the flavour of reduced-salt dry sausages.

Summary: The protease generated from Staphylococcus xylosus A2 isolated from Harbin dry sausages was purified and characterized. It showed the highest relative activity at pH 6.0 and 50 degrees C, while maintaining stability within pH 4.0-8.0 and temperatures of 20-50 degrees C. The protease's activity was enhanced by Ca2+ and Zn2+ ions, and it exhibited better catalytic properties at 40 degrees C. Additionally, the hydrolysate obtained from the protease was non-cytotoxic to HEK-293 cells. These findings provide insights into the enzymatic characterization of S. xylosus A2 protease and its potential application in fermented meat products.

Summary: This study investigated the flavor differences among different parts of Jingpo Lake grass carp (JPGC) and commercial grass carp (CGC). The growing environment and fish parts influenced the volatile compounds of the fish. The combination of electronic tongue and electronic nose could effectively distinguish the flavor differences between the different parts of JPGC and CGC. The content of total free amino acids and amino acids contributing to sweet and fresh flavors were higher in JPGC than CGC. Sensory evaluation indicated that JPGC had a better texture, odor, and taste compared to CGC.

Summary: This study investigated the physicochemical properties of five vegetable oils (peanut, corn, rapeseed, sunflower seed, and soybean) and their impact on the development of heterocyclic aromatic amines (HAAs) in pan-fried bacon. The results showed that the type of vegetable oil used affected the color of the fried bacon but not the flavor and taste. To reduce HAA concentrations, the selection of appropriate vegetable oil should be considered.

Summary: This study investigated the effects of different concentrations of Abelmoschus manihot gum (AMG) on the gel properties and in vitro digestibility of frankfurters. The results showed that AMG incorporation improved the emulsion stability, texture, and rheological characteristics of frankfurters, with the optimal concentration being 0.3%. Hydrogen bonds and disulphide bonds were the main molecular forces in the presence of AMG. Microstructural analysis revealed more uniform and dense microstructures in frankfurters with AMG supplementation. Additionally, AMG incorporation increased the in vitro protein digestibility of frankfurters. These findings have practical implications for the production of emulsified meat products.
