Abstract
Pulsed light for sanitation of berries is considered a non-thermal technology able to control the microbial population of ready-to-eat vacuum-packed products. This technology has also been evaluated as pre-treatment for grapes in order to reduce native microorganisms located in the pruina of grapes. The reduction of microorganism counts would allow the use of culture starters to express the floral and fruity character of the yeast-related metabolites produced during winemaking. Here we describe the protocols followed for the treatment of immobilized and non-immobilized destemmed grapes in laboratory-scale PL cabinet and the growth media with the aim of knowing the microbial counts in any time.
