Model fit based on the weight loss and texture parameters of MAP cherry tomatoes during storage

We investigate the mathematical correlation between weight loss and texture characteristics of modified atmosphere packaging (MAP) for cherry tomatoes (Solanum lycopersicum). In this study, the Slogstic1 model showed that the weight loss of cherry tomatoes with MAP increased with prolonged storage time at room temperature. Moreover, this weight loss had a negative influence on all the texture parameters. Taking weight loss as a dependent variable, the texture parameters of firmness, cohesiveness, gumminess, chewiness, and resilience were significantly related to weight loss as independent variables and used to establish the fitting functions. With an increase in weight loss, the changes in firmness, cohesiveness, gumminess, chewiness, and resilience were consistent with the Log3P1, Gauss, Logistic, Boltzmann, and GaussAmp models, respectively. The result will provide useful information for predicting the weight loss and evaluating the texture of MAP fruit quantitatively. Novelty impact statement The weight loss of MAP cherry tomatoes conformed to the Slogstic1 growth model. The weight loss had the strongest negative correlation with firmness. With increasing weight loss, the changes in firmness, cohesiveness, gumminess, chewiness, and resilience matched the Log3P1, Gauss, Logistic, Boltzmann, and GaussAmp models, respectively.
