Summary: The study found that the removal of CCPs affects the structural modification of casein micelle, but the loss of CCPs is not always equivalent to the reduction in total calcium and phosphorous ions. Demineralization results in the total depletion of some CCPs, while the decrease in Hard regions is not directly correlated to the decrease in CCPs.

Summary: This study used Atomic Force Microscopy (AFM) to evaluate the nanomechanical properties of individual casein micelles (CMs) following physico-chemical modifications known to affect the content of insoluble micellar calcium phosphate (MCP) and the rheology of enzymatic milk gel. The research showed that a decrease or increase in MCP content by +/- 18-24% w/w resulted in a significant decrease or increase in the Young modulus of CMs, respectively. These findings suggest that variations in the modulus of individual CMs could explain the changes in the macroscopic properties of milk gel.

Summary: Sodium caseinate, an amphiphilic protein derived from natural products, is currently used in the production of edible films. To enhance its properties, particularly its hydrophilicity and water solubility, a chemical modification is proposed by grafting a hydrophobic fatty acid, oleic acid, onto the caseinate. A new synthesis method utilizing acid chloride derivative and phase transfer catalysis is described, resulting in a caseinate derivative with a high substitution degree (>50%).

Summary: In this study, the coagulation and digestion of caprine and bovine micellar casein concentrate (MCC) were examined under simulated adult and elderly conditions, with or without partial colloidal calcium depletion (deCa). The results showed that caprine MCC formed smaller and looser gastric clots compared to bovine MCC, and these clots became even looser with deCa and under elderly condition. Caprine MCC underwent faster casein hydrolysis and formation of large peptides than bovine MCC, especially with deCa and under adult condition. Additionally, caprine MCC showed faster formation of free amino groups and small peptides, particularly with deCa and under adult condition. Upon intestinal digestion, proteolysis occurred rapidly, especially under adult condition, with less difference between caprine and bovine MCC and with and without deCa.

Summary: Re-assembled casein micelles (rCMs) were developed in the 1970s to mimic the native casein micelles (nCMs) in milk. They have been extensively studied to understand their formation process and stability. Recent research has explored their applications as nanocarriers and electrode-bound substrates, but their potential in food and non-food industries is not fully realized. Compared to nCMs, rCMs offer advantages of easier preparation and higher purity, making them promising as encapsulants and dairy ingredients.

Summary: Casein and its sodium salt, sodium caseinate, are used as biodegradable biomaterials, particularly in the production of packaging films. Blending with other biodegradable polymers, such as PLA and PCL, can enhance their properties. New graft copolymers of SC-g-PLA and SC-g-PCL with high grafting degrees have been prepared and characterized. The addition of these copolymers affects the properties and microstructures of SC/PLA and SC/PCL blends, demonstrating their compatibilization capacity.

Summary: This study investigated the effect of UHT treatment and pH values on the physical properties of sheep skim milk. It was found that significant sedimentation occurred in UHT-treated milk at natural pH and pH 7.0, while lower sedimentation was observed at pH values of 6.7 to 6.9. Additionally, UHT treatment resulted in decreased pH and ionic calcium level of the milk.

Summary: Fabrication of bead-free nanofibers from pure casein is challenging due to its self-aggregation tendency. In this study, the influence of pH, ethanol content, ionic environment, and casein concentration on the solubility and solution characteristics of casein-based spinning dopes was analyzed. The addition of tetrasodium pyrophosphate (TSPP) reduced bead defects and improved the properties of the nanofibers. The viscosity of the solution depended on the casein concentration, and bead-free nanofibers were obtained at a concentration higher than the entanglement concentration (C-e).

Summary: Phycocyanin, a protein prone to degradation under acidic conditions and unstable at high temperatures, has limited application in food. This study successfully combined phycocyanin with whey protein isolate using protein coprecipitation and chitosan coating to form composite particles, which maintained the color and colloidal stability of phycocyanin. The composite particles showed minimal color changes and retained high pigment retention rates after heating. Furthermore, the composite particles exhibited excellent antioxidant capacity. This breakthrough expands the application of phycocyanin in acidic beverages and other food forms.

Summary: This study investigated the synergetic gelation of curdlan gum (CG) and gellan gum (GG) at different ratios. The optimal gelation was achieved at a mass ratio of 1:1 and a total concentration of 0.6%. The gel properties were influenced by the CG/GG ratio, with the strongest gel observed at a ratio of 5:5. The improved gel properties were attributed to hydrogen bonds between CG and GG. The CG/GG binary composite gel exhibited increased water holding capacity as the CG/GG ratio decreased. Furthermore, the microstructure of the CG/GG gel was denser and more homogeneous, supporting its stronger gel rigidity and water holding capacity.
