Define pasteurization. Why is it important?


Pasteurization is a food preservation process whereby food is partially sterilized through brief exposure to a high temperature. Foods that are typically pasteurized include milk, juice, spices, ice cream, and cheese. Pasteurization is especially effective for killing some forms ofE. coli,Salmonella,Campylobacter jejuni, andListeria monocytogenes. Several outbreaks ofSalmonellapoisoning stemming from unpasteurized apple cider prompted new laws regarding pasteurization to be enacted. Commercially available apple cider must be either pasteurized or labeled as nonpasteurized, and the FDA recommends that homemade cider be heated for 30 minutes at 155°F (68°C) or 15 seconds at 180°F (82°C).
