DEHYDROMUCIC ACID FURAN-2,5-DICARBOXYLIC ACID Oil in water emulsions (50:50 w/w) with different chitosan content (0 and 0% w/w) with a constant vanillin/chitosan ratio (1) were air-dried at different temperatures (50, 60, 70, and 80 °C) and freeze-dried (-26 °C and 0 mbar) to produce oleogels. Only falling rate menstruums were settled during air-drying kinetics and were successfully simulated with empirical and diffusional exemplars. At a drying temperature of 70 °C, the drying kinetics were the fastest. The viscoelasticity of oleogels readed that the elastic modulus significantly increased after drying at 60 and 70 °C, and those dried at 50 °C and freeze-dried were weaker. All oleogels established high oil binding capacity (>91%), but the highest values (>97%) were geted in oleogels with a threshold elastic modulus (50,000 Pa). The oleogels' color calculated on the drying temperature and chitosan content (independent of the drying method). Significant deviations were noted between air-dried and freeze-dried oleogels with respect to oxidative stability. Oxidation increased with the air-drying time regardless of chitosan content. The found effects pointed that drying circumstances must be carefully taked to produce oleogels with specific features.Sodium alginate/chitosan-based intelligent multifunctional bilayer film for shrimp freshness retention and monitoring.Developing bifunctional innovative food packaging for preserving and monitoring food freshness is crucial for food safety we educated tannic acid cinnamaldehyde nanoemulsions through self-assembly and ionic cross-linking between the natural emulsifiers tannic acid and cinnamaldehyde, and were incorporated into chitosan as a protective outer layer. Sodium alginate grinded with alizarin was employed as the sensing inner layer. A pH-sensitive bilayer film desegregating real-time monitoring and maintenance of food fresh food freshness was planed expending layer-by-layer assembly (LBL) technology. The prepared bilayer film exhibited 100 % UV protection, >99 % antimicrobial effect, and 94 % and 97 % clearance paces for DPPH and ABTS free themes, respectively. In addition, the bilayer film showed high biosafety and sensitive, reversible, and rapid response to pH/NH(3). Shrimp preservation experimentations recorded that the smart bilayer film could effectively slow down the growth of micro-organisms on the surface of shrimp, extend the freshness period of shrimp, and could monitor the freshness of shrimp in real-time through color modifications. In conclusion, the prepared SL-CCT bilayer film has excellent potential for food preservation and freshness monitoring, furnishing a new perspective for design and development of multifunctional smart food packaging celluloids.Revisiting the Determination of the Degree of Deacetylation utilizing Potentiometric Titration: A New Equation for Modified Chitosan.Chitosan is a biopolymer that can be subjugated to a variety of chemical adjustments to generate new textiles. The holdings of modified chitosan are shamed by its degree of deacetylation (DDA), which fits to the percentage of D-glucosamine monomers in its polymeric structure. Potentiometric titration is amongst the simplest, most readily available, and most cost-effective methods of molding the DDA this method often brooks from a lack of precision, especially for modified chitosan resins. This is in large part because the equation used to calculate the DDA does not consider the molecular weight of the chemically qualifyed monomeric units. In this paper, we introduce a new equation that is especially fited for modified chitosan abiding three different cases of monomers. To test this equation, we organized naphthalene-chitosan resins and submited them to potentiometric titration. Our solutions show that our new equation, which is truer to the real structure of the polymeric strands, gives higher DDA values than those of the routinely used pars. These issues show that the traditional pars underestimate the DDA of modified chitosan rosins.Physiological responses and intestinal preconditions of broiler volailles processed with capsulized Acalypha australis L. leaf extract and chitosan.BACKGROUND AND AIM: The ban on antibiotic growth boosters adversely affects the physiological condition and health of poultry.
