Desarrollo de peliculas comestibles para la conservacion de hongos (Pleurotus sp)

Abstract

The Development of edible films for the conservation of fungi (Pleurotus sp) emerged with the purpose of increasing the shelf life of food through the development and application of films based on candelilla wax. Five formulas were experimented, which were developed according to the proposed by Oregel et al. In 2016 with some modifications, the formula F1 (Guar Gum 0.8%, Candelilla Wax 0.2%, Glycerol 0.3%), F2 (Guar Gum 0.8%, Candelilla Wax 0.4%, Glycerol 0.2%), F3 (Guar Gum 1.2%, Wax 0.2% candelilla, 0.2% glycerol) and F4 (1.2% guar gum, 0.4% candelilla wax, Glycerol 0.3%) and F5 with the same proportion of F4 ingredients but with the addition of the three preservatives. The elaboration of the films was carried out in 2 stages of experimentation at T = 4 ° C and T = 30 ° C for 15 days. Characteristics such as texture, color and appearance were evaluated, the best evaluated formula was FB5 with a lifespan of ten days at T = 4 ° C, which allowed to increase the shelf life of the fresh product by a 100%.
