Chitosan-Based Oleogels: Emulsion Drying Kinetics and Physical, Rheological, and Textural Characteristics of Olive Oil Oleogels

Marine Drugs, Journal Year: 2024, Volume and Issue: 22(7), P. 318 - 318

Published: July 17, 2024

Oleogels are of high interest as promising substitutes for trans fats in foods. An emulsion-templated method was used to trap olive oil the chitosan crosslinked with vanillin matrix. Oil water emulsions (50:50 w/w) different content (0.7 and 0.8% a constant vanillin/chitosan ratio (1.3) were air-dried at temperatures (50, 60, 70, 80 °C) freeze-dried (-26 °C 0.1 mbar) produce oleogels. Only falling rate periods determined during air-drying kinetics successfully modeled empirical diffusional models. At drying temperature 70 °C, fastest. The viscoelasticity oleogels showed that elastic modulus significantly increased after 60 those dried 50 weaker. All binding capacity (>91%), but highest values (>97%) obtained threshold (50,000 Pa). oleogels' color depended on (independent method). Significant differences observed between respect oxidative stability. Oxidation time regardless content. found results indicated conditions must be carefully selected specific features.

Chitin and chitosan are valuable biopolymers with various applications, ranging from food to pharmaceuticals. Traditionally sourced crustaceans, the rising demand for chitin/chitosan, paired development of insect sector, has led exploration biomass its byproducts as a potential source. Conventional processes rely on hazardous chemicals, raising environmental concerns. This critical review evaluates emerging "greener" approaches, including biological methods, green solvents, advanced processing techniques, chitin/chitosan production insect-derived materials such exuviae cocoons. Two systematic evaluations included: (1) cross-comparison chitin yields across life stages (e.g., up 35.7% black soldier fly (BSF) larval exoskeletons can be obtained) (2) stepwise sustainability assessment over 30 extraction workflows reported 16 studies. While many labeled green, only few, bromelain, lactic acid fermentations, or NADES-based processes, demonstrated fully stage. No study achieved conversion chitosan, typically required low fat content minimal pretreatment. These findings will useful identify opportunities underscore need refine greener improve yields, reduce impurities, enable industrial-scale production, while data generated.
