Abstract
In this study, vitamin A and {beta}-carotene contents and the percent of activity retention were analyzed in 3 kGy and 30 kGy {sup 60}Co {gamma}-irradiated samples of bovine liver and swine liver pate. Six different lots of liver samples weighing 100 g obtained at the meat market were employed. Irradiation was performed with liver samples initially frozen (-15 deg C). Similarly, six different lots of swine liver pate samples weighing about 100 - 125 g , at temperature of 7 deg C were irradiated. Pre-treatments and analysis methods were those described in Instituto Adolfo Lutz Norms for food analyses. Two and five- gram samples in duplicates for bovine liver and five gram-samples for swine liver pate were used. The results showed that there were no losses of either vitamin A or provitamin A activities in the samples of bovine liver and swine liver pate irradiated with a dose of 3 kGy (retention about 100%). On the other hand, for swine liver pate samples of vitamin A were maintained after irradiation with 30 kGy. (author)
