Summary: The research found that the optimal pH for coacervation between NaCas and HMP is at pH 3.30, where the complex shows the highest turbidity, particle size, and viscosity. The best coacervation condition was achieved at a ratio of 4:1 and a total biopolymer concentration of 0.4% w/v. Increasing the total concentration of biopolymers shifted the NaCas/pectin ratio to higher pH values. The maximum coacervate yield was achieved at 39.8% w/w with a ratio of 4:1 of NaCas/HMP and a total biopolymer concentration of 0.4% w/v.

Summary: This study developed a method combining gelatin-SHMP complex coacervation and freeze-drying with the aid of SSOS for the preparation of fish oil-encapsulated powders. The choice of gelatin type and the pH of the solution were critical factors in preparing the complex coacervates. SSOS was found to improve the encapsulation efficiency. The fish oil-encapsulated powders had similar loading capacity but different encapsulation efficiency values, and their digestion and release of free fatty acids depended on the gelatin source. This work provides valuable information for the development of powder foods using gelatin, fish oil, and SSOS.

Summary: Proteins and polysaccharides are commonly used to prepare eco-friendly packaging materials. However, films based on proteins or polysaccharides alone often have poor performance, so combining them is necessary to improve properties. In this study, enzyme technology was used to prepare films with sodium caseinate-carboxymethyl chitosan, incorporating epigallocatechin gallate as bridging molecules and antibacterial agents. The films showed improved mechanical properties, antibacterial activity, and free radical scavenging ability with the increase of epigallocatechin gallate and tyrosinase content. This work provides an efficient enzymatic method to prepare films with good strength and antibacterial properties for improving food storage quality.

Summary: This study aimed to improve the physical, mechanical, and biological properties of a monolayer pectin (P) film containing nanoemulsified trans-Cinnamaldehyde (TC) by incorporating it between inner and outer layers of ethylcellulose (EC). The addition of the nanoemulsion increased the opacity of the film, reduced its moisture absorption capacity, and improved its antimicrobial activity. However, the tensile strength and elongation at break of the pectin films decreased after the incorporation of nanoemulsions. Multilayer films (EC/P/EC) showed a higher resistance to breaking and better extensibility compared to monolayer films. The antimicrobial activity of both mono and multilayer films was effective in inhibiting the growth of foodborne bacteria during storage of ground beef patties at 8 degrees C for 10 days. This study suggests that biodegradable antimicrobial multilayer packaging films can be effectively designed and applied in the food packaging industry.

Summary: Two plant-based emulsifiers, soybean lecithin and pea protein isolate, were tested for their ability to emulsify and encapsulate trans-cinnamaldehyde (TC) at different pH levels and after drying with different techniques. The spray-dried powders showed higher encapsulation efficiency (EE) than the freeze-dried powders, but the water content of the freeze-dried powders was lower. Powders prepared at pH 3 exhibited better thermal stability. The resulting powders and nanoemulsions demonstrated antimicrobial activity against E. coli and L. innocua, highlighting their potential as natural preservatives in food.

Summary: In this study, a highly effective surfactant producer strain, Bacillus Cereus GX7, was isolated from the oil tank bottom sludge of Shengli Oil Field in China. The biosurfactant produced by GX7 was identified as surfactin, a lipopeptide surfactant, through TLC, FT-IR, and LC-MS/MS analysis. The fermentation process of GX7 was optimized using single-factor experiments, focusing on the composition of fermentation medium and fermentation conditions. Glucose and peptone were found to be the best carbon and nitrogen sources, and the optimum temperature, inoculum amount, pH, rotation speed, and fermentation time for the strain were determined to be 30°C, 1%, 7.5, 150 rpm, and 48 h, respectively. After optimization, the surface tension and emulsification index of the fermentation broth were 26.84 mN/m and 57.84%, respectively. Furthermore, the biosurfactant produced by GX7 demonstrated good stability over a wide range of temperature, pH, and salt concentration.
