combination of ultrasound with other preservation process such as heat, high pressure, or ultraviolet irradiations has also been investigated and shown to have good potential for industrial applications [7]. Use of UV light as a treatment process is gaining tremendous attention as it holds considerable promise in food processing [8,9]. The UV germicidal effect is based on the absorption of light photons by exposed cells and damage to the DNA due to thymine dimer formation, which destroys the ability of microorganisms to grow [10,2]. The wavelength of 254 nm (UV-C) has the highest germicidal effect and is used for disinfection of surfaces,
water and certain food products. The advantage of UV radiation, as a non-thermal treatment, is that the organoleptic properties may be enhanced with limited changes to the nutrients present
in the liquid. Combining ultrasound in a hurdle technology with ultraviolet treatment can potentially enhance the overall quality of minimally processed foods as this can reduce the treatment times and can work in complimentary manner with the UV irradiations.
