Comparación del crecimiento microbiano en conservación de distintos vegetales en refrigeradores de tipo A y tipo B

Abstract

In the present study we analyzed a comparison between the microbial growth in the conservation of different vegetables that they were stored in the refrigerator type A and type B. We considered three different vegetables: “white onion”, spinach and lettuce. They were obtained in the Market “10 de Agosto”. For counting of indicator microorganisms such aerobic mesophilic, molds and yeasts, the vegetables were refrigerated in the type A and type B system. Later, we did an initial recount at time zero in the moment we got the vegetables, seven days after of staying in refrigeration in the both systems, and also 15 days after in the same conditions. The results of the recounts were analyzed statistically with the test “T student”. We demonstrated that the aerobic mesophilic recount had significant difference between the two systems, meanwhile, in the molds and yeasts recount did not have significant difference. They showed that the refrigerator type A could be better in the conservation of vegetables.
