Application of a TTI‐based Distribution Management System for Quality Optimization of Frozen Vegetables at the Consumer End

The applicability of Time Temperature Integrators (TTI) for frozen chain management was assessed. Shelf life kinetics indices of frozen green peas and white mushrooms and response kinetics of suitable enzymatic TTI were used to confirm the monitoring effectiveness of TTI, in a controlled field test with 200 products. Comparison to actual measurements of quality indices showed that TTI response provides a reliable indication of the relative quality status of the products. The potential of Least Shelf-Life First Out (LSFO) system, a TTI based management system for frozen product distribution and stock rotation, was demonstrated by Monte Carlo technique that showed consistent, acceptable quality and minimization of rejected products at the consumer end.
