The green banana flour (Musa spp.) was treated with gamma irradiation at doses 1.0 and 3.0 kGy and its changes were evaluated in relation to vitamin B1 and C content, besides nutritional properties. Vitamin B1 was determined using fluorescence quantification produced by thiochrome compound. Vitamin C was determined by UV/VIS spectrophotometric method. The physicochemical analyses were performed by standard methods. No loss of vitamins B1 and C was found at assayed -irradiation doses. Also, there is no considerable difference for physicochemical properties of the Brazilian green banana flour. As it was showed, the nutritional value of irradiated food is preserved. Then, the application of the irradiation technology for food may be recommended.
