The effect of UV-C radiation (in vitro tests: 4 W m-2, for 20 min) on the conidia four more frequent and abundant molds isolated from blueberry (Aspergillus niger, Arthrinium phaeospermun, Penicillium decumbens, Eurotium repens) was modeled. reduction in mold counts occurred up to 10 minutes treatment. selected treatment applied samples inoculated with two most resistant vivo Aspergillus niger phaeospermun). (2,4 kJ minutes) slightly increased pH value without significantly modifying soluble solids content, firmness, color blueberries. Treatment concentration total phenols (13%) antioxidant capacity blueberries (8%) compared untreated sample. It is essential identify contaminating microflora correctly apply dose maintained attributes related sensory quality, increasing content phenolic compounds,
