Food Sensory Facilities
The sensory facilities are located in Townsend Hall, 529 S College Ave, toom, 120, Newark, Delaware, 19716. Recently renovated, the space includes a waiting area, a testing area with 10 individual booths, and a food-grade kitchen for sample preparation.
The facility can accommodate 30 to 50 panelists per sensory session (per day) for a range of acceptance and discrimination tests. Additionally, we have the capability to recruit and maintain a trained sensory panel for descriptive analysis. We utilize RedJade as our platform for developing questionnaires, conducting data analysis, and generating reports.
Shelf-life study capacities
Our laboratory maintains a comprehensive infrastructure for conducting shelf-life studies on both fresh produce and processed food products under controlled storage conditions. The facility is equipped with multiple walk-in refrigerators and walk-in freezers to accommodate large-scale storage trials across a wide range of temperatures, as well as a programmable smart oven/incubator that enables precise control of temperature and humidity for accelerated shelf-life testing and environmental simulations.
Complementing these storage capabilities is a complete suite of analytical instrumentation for monitoring product quality throughout storage, including gas sensors for package headspace (Oâ‚‚, COâ‚‚, and other gases), colorimeters for objective color evaluation, water activity meters, moisture analyzers, texture analyzers, pH meters, and other physicochemical characterization tools.
These capabilities enable comprehensive evaluation of quality attributes, package atmosphere, microbial stability, and shelf-life performance for fresh fruits and vegetables, snacks, baked products, beverages, and other processed foods under both conventional and modified storage conditions.
