Gamma irradiation of mango 'Ataulfo' at low dose: Effect on texture, taste, and odor fruit

Abstract

Sensory descriptors of mango 'Ataulfo' treated with dose of γ-rad (Cobalt 60) of 0, 0.15, 0.30, and 0.45 kGys were evaluated. Eight trained panelists evaluated eleven sensory descriptors, three on taste, four on texture and four on odor. Judges found significant differences (P < 0.05) for sweetness, sourness, astringency, juiciness, firmness, mango odor and honey odor in at least one treatment. The principal component analysis revealed a positively association between juiciness, mango odor, and honey odor with the irradiation dose of 0.30 kGy, besides the positively association between creaminess and the irradiation dose of 0.15 kGy. Any descriptors were influenced clearly by the radiation with dose at 0.45 kGy. Dose of 0.15 kGy of radiation can be used as phytosanitary treatment without substantially affecting the sensory properties of mango 'Ataulfo'.
