Use of E-Beam for Shelf-Life Extension and Sanitizing of Marinated Pork Loin

Abstract EN

The effectiveness of E-beam radiation to extend the shelf-life of marinated pork loin slices stored at 4 and 8°C (temperature abuse) has been studied.

The shelf-life was extended from 7 to 16 and >20 days after the application of 1 and 2 kGy, respectively.

In the event of a temperature abuse occuring during the product distribution (e.g., increase to 8°C), the shelf-life would be extended from 5 to 10 and 16 days, respectively, when applying the doses mentioned previously.

From a public health point of view, the irradiation of marinated pork loin may be marketable for a longer period of time of up to two weeks, and guarantees a practically Salmonella and Listeria-free product.

Minor changes are produced by the E-beam treatment in the main sensory and rheological characteristics.

The odor was the most affected feature, but the off-odors diminished with increased storage.

In any case, testers judged the samples to be adequate for marketing.
