Minimally processed non-irradiated carrots (sliced) exhibited diverse microflora at initial level. During storage, bacterial number increased with the presence of pathogenic bacteria accompanied by a loss of total solids. On the other hand Υ-irradiation at an optimal dose of 2kGy offered a pathogen-free, hygienic product with insignificant losses in nutrients such as in sucrose, total carotenes and ascorbic acid content in comparison to controls and 2- to 4-fold incr eased in shelf-life at refrigeration temperature. The D10values of pathogens like Escherichia coli and Yersinia enterocolitica in carrot paste were in a lower range (0.12–0.26kGy) compared with that of Listeria monocytogenes (0.3–0.5kGy). The validity of the processing treatment (2kGy) was challenged by artificially inoculating Listeria monocytogenes in the product. Thus, minimally processed carrots (sliced) are amenable to radiation treatment for extended storage stability and microbial safety.
