Protein nutrition has been shown to stimulate and strengthen the immune system, and such approaches are needed for this growing segment of the population.

Reduction of microbial load through UV light application as a disinfection medium for food products other than liquids is also being studied. On the other hand, variables such as flow rate, exposure time, type of fruit product, juice colour and juice composition, among other variables, need to be studied to obtain fruit products with reduced microbial load, increased shelf life and adequate sensory and nutritional characteristics. Juices from different sources can be treated by exposure to UV light at different doses. However, pasteurisation can change the taste and flavour of such products because of the temperature and processing time.

Today, most of these products are pasteurised to obtain microbiologically safe and nutritious products. Pumpable fruit and vegetable products are generally very suitable for processing by UV light to reduce the microbial load. Water has been treated with UV light to obtain drinking water for quite some time.
