Apple porridge submitted to gamma radiation for shelf-life extended

Abstract

Among many apple products, apple porridge is a popular product nowadays. It is a practical, healthy and tasty product that can be consumed throughout the day. However, it is an extremely perishable product. Therefore, the aim of this work was to evaluate the shelf-life period of apple porridge after the application of gamma radiation as a conservation technology. After the formulation of apple porridge was developed, which was subjected to gamma radiation at the dose of 1kGy in a dose tax of 0.356 kGy.hour-1 and compared this treatment with the control group (0kGy). From the results presented, it can be concluded that the conservation period of apple porridge submitted to gamma radiation is 60 days. From the 90th day, the samples showed microbial growth, becoming not accepted for consumption. In comparison to the control group, the use of gamma radiation was promising, since the standard sample showed contamination before 30 days. By the results it can be concluded that the dose used was adequate for the conservation of this product for the period evaluated.
