Food Preservation Techniques

Sorcha-Wainwright is a food-science instructor with a Ph.D. in Food Technology, focusing on preservation-method fundamentals such as canning, freezing, and drying. She has developed lab protocols on microbial-stability testing, water-activity measurement, and shelf-life modeling. Sorcha publishes recipe-standardization guides and HACCP-based sanitation plans for preservation workflows. She leads demonstrations on novel preservation techniques like high-pressure processing and pulsed-electric fields. Her ongoing research evaluates thermal-nonthermal hybrid methods for nutrient retention and safety assurance.
