Vegetable spoilage at low temperatures by two psychrotrophic bacteria.

Altération de légumes par deux bactéries psychrotrophes à basse température.

Author(s) : MEMBRÉ J. M., KUBACZKA M., DIETTE A.

Summary

Predictive models described the effect of environmental factors on growth parameters of microorganisms. With vegetable foods, predictive microbiology approach must be applied to both pectinolytic enzyme activity and vegetable damage rate. In this paper, Pseudomonas marginalis and Chryseomonas luteola were chosen because of their ability to grow on postharvest vegetables. Studies were performed at 7°C with low initial bacterial concentrations. Results obtained in synthetic medium were validated in carrot juice. The use of predictive microbiology tools in food spoilage, particularly in vegetable damage kinetics, is discussed.
