Abstract
Statistical and sensitivity analyses of the Michaëlis-Menten (M-M) kinetics used in respiration rate (RR) modeling of fresh produce during MAP was carried out.
Monte Carlo (M-C) simulation showed that the PCO2 term was the most sensitive.
This term was modified by adding an exponential term, PCO2|m, and substituted back into M-M, improving its stability and prediction accuracy.
The analysis was based on the RR of fresh-cut lettuce (Lactuca sativa var. longifolia) treated with sodium hypochlorite solution (100 ppm) and by ascorbic and citric acid solution, (1% w/v each) and stored at 4.18°C for 7 days.
The RR in both cases was significantly affected by the disinfection methods, storage time and their interaction.
