Cheese emulsion is an intermediate product for the production of cheese powder and needs to be stable, homogeneous and pumpable characteristics to convey to the spray drier. This study was conducted to evaluate the effects of fat reduction and emulsifying salt (ES) amount in cheese emulsion systems on the physicochemical characteristics. Reduced-fat (RF) and full-fat (FF) white-brined cheese emulsions were produced with different dry matters (DM; 15%-25% excluding ES) and ES concentrations (0%-3% based on cheese weight). Stable cheese emulsion was obtained at lower DM in RF cheese emulsion than that of FF cheese emulsion. Reduction in the amount of ES resulted in instability of both emulsions. Apparent viscosity with pseudoplastic flow behavior significantly increased with the decrease of fat content in stable cheese emulsions. Microstructure of emulsions appeared to be related to the fat content, stability and degree of emulsification. Reduction of fat content caused to get less lightness and more greenness in color, whereas yellowness was significantly decreased by increase in the amount of ES. In conclusion, fat reduction resulted in higher viscosities of cheese emulsion due to inducing the increment of protein, and the addition amount of ES considered as very important factor to produce stable cheese emulsion without protein precipitation or cream separation. Therefore, for preparation of RF cheese emulsion using a variety of white-brined cheese, lower amounts of DM would be suggested in this study to obtain homogenous droplets in the atomizing process of spray drying.

The aim of the present research was to evaluate the effect of Urtica dioica L. (nettle) essential oil (in the forms of Pickering nanoemulsion (NEO) and free (EO)) on microbial, chemical and sensory changes of pizza cheese stored at 4 °C for 12 days. For this purpose, Escherichia coli and Listeria monocytogenes were inoculated into pizza cheese.

Inner Mongolian cheese is easily spoiled during storage due to hydrolysis and microbial contamination. Herein, the guar gum (GG)/chitosan (CS) edible films reinforced with orange essential oil nanoemulsion (OEON) were fabricated for cheese preservation. Results showed 4 % OEON with the optimal droplet size (380 ± 44.

Pea protein is a promising ingredient for plant-based cheese production but has poor consumer acceptance due to intrinsic beany flavors. Fermentation could potentially decrease these off-flavors while also producing desirable cheese-like aromas. Pea protein emulsion gels were fermented using four different bacterial blends for 16 weeks with and without the crosslinking enzyme transglutaminase.

Phospholipids from different sources have varying chemical compositions, but how they contribute to different properties of infant formula is unclear. In this study, four types of phospholipids, milk phospholipids (MPLs), soybean phospholipids (SBPLs), sunflower phospholipids (SFPLs), and egg yolk phospholipids (EYPLs), were added to infant formula to investigate their physicochemical properties, microstructure, and surface characteristics. MPLs uniquely offer high sphingomyelin and saturated fatty acid levels.

In dairy-based imitation mozzarella cheese (IMC) formulations, intact casein is critical and imparts IMC with a firm and elastic, stringy, melted texture. Rennet casein (RCN) is the desired ingredient to provide intact casein in IMC and is preferred over milk protein concentrate (MPC) and micellar casein concentrate (MCC). Transglutaminase (TGase), a crosslinking enzyme, alters the physical properties of MPC or MCC and may change IMC functionality.
