Chitosan oleogels for sustainable fat replacement in confectionery

Overview

Chitosan oleogels present a groundbreaking solution for the confectionery industry by offering a sustainable, scalable, and functional alternative to traditional solid fats like hydrogenated fats, butter, and palm fat. Developed using a novel emulsion-templated method, these oleogels effectively mimic the characteristics of conventional fats, ensuring that texture and structure in products such as cookies and ice cream are preserved. Additionally, chitosan oleogels help control fatty acid release during digestion, suggesting potential health benefits that make them an attractive option for health-conscious consumers.

Technical specifications

The chitosan oleogels are created through a process involving emulsification, freeze-drying, and mechanical shearing. Using commodity oils such as soybean or canola oil, these oleogels achieve over 80% similarity to traditional fats in terms of plasticity. The oleogels are crosslinked with vanillin to enhance their structural integrity and are adjustable in terms of thermal stability and hardness by manipulating chitosan concentration, oil type, and storage conditions. This adaptability allows them to be tailored for various confectionery products, including chocolates, spreads, and pastries.

Technology readiness level

Currently, the chitosan oleogels are at Technology Readiness Level 4, with ongoing work to scale up production and optimize parameters for broader application in confectionery. The research plan includes economic feasibility studies, in vitro digestion analyses, and collaborations to extend their use in additional products like ganaches and glazes.
