Summary:The aim of this study was to evaluate the effect of different packaging with modified atmosphere on the microbiological aspects and sensory acceptance of minimally processed eKumagai f and ePedro Sato' guavas. Mix of eKumagai f and ePedro Sato, in slices were wrapped in different packaging materials and stored at 5oC for six days. The packaging materials used were:polyethylene terephthalate containers; polypropylene bag 52 Êm; polyolefin film Cryovac PD-900 58 Êm; PVC stretch film 17 Êm. Aciduric microorganisms, total coliforms and at 45oC and the presence / absence of Salmonella were analyzed. For the sensory evaluation was applied to the acceptance test. The guavas minimally processed wrapped PVC stretch film and PP film obtained greater acceptance for the sensory attribute appearance. The acceptance for the sensory attribute flavor of minimally processed guavas was positive in all treatments. The packaging did not affect the microbiological aspects of products, which showed low microbial count, in accordance with current legislation. O objetivo deste trabalho foi avaliar o efeito de diferentes embalagens com atmosfera modificada na qualidade microbiologica e sensorial de goiabas eKumagai f e ePedro Sato f minimamente processadas. Mix de goiabas eKumagai f e ePedro Sato f, em rodelas, foram embaladas em diferentes materiais de embalagem e armazenadas a 5oC, 70%UR por seis dias. Os materiais de embalagem utilizados foram: embalagens de tereftalato de polietileno (PET); filme de polipropileno de 52 Êm de espessura (PP); filme poliolefinico da Cryovac de 58 Êm (PD- 900); filme de policloreto de vinil de 17 Êm (PVC). Avaliou-se a contagem de microrganismos aciduricos, coliformes totais e a 45oC e presenca/ausencia de Salmonella. Para avaliacao sensorial aplicou-se o teste de aceitacao. As goiabas minimamente processadas e acondicionadas em embalagem de PVC e PP obtiveram maior aceitacao sensorial referente ao atributo aparencia. A aceitacao sensorial referente ao atributo sabor das goiabas minimamente processadas foi positiva em todos os tratamentos. A embalagem nao influenciou os aspectos microbiologicos dos produtos, que apresentaram baixa contagem microbiana, em acordo com a legislacao vigente.
