Résumé:
Propolis is a resinous substance and balsamic mixture that bees of the
cies Ápfs me///fera 1. collect from various plants and lead to the hive. A viable
alternative microbial reduction in fruit and vegetables is the protection during
transport and storage with biofilms biodegradable. Given that the aim of this
study was to evaluate the effect of biofilms edible base red propolis extract in
different concentrations on postharvest preservation of Niagara rosada table
grape. Were then compiled two formulations of biofilms, applied in grapes and
stored temperatures of 7 C and 35 C for 21 days. The samples were analyzed
as its physical, chemical and microbiological characteristics, for fu rther
verification of the efficiency of the biofilms the base red propolis extract: We
concluded that the treatments in Niagara rosada grape samples using biofilms
red propolis derived from Da/berg/a ecasfophy//um (3 and 5%) associated with
temperature, interference in the development of micro-organisms studied in this
research. For all treatments applied there was significant variation of the leveis
of moisture and ash, with the exception of the efficiency of the biofilm and
biofilm 2 1, temperatures of 7' C and 35' C, respectively for the parameter of
total soluble solids (' Brix), this occurred because the barrier formed by the
biofilms in function of the degradation of sugars present in fruits.
