Final answer:
Food processing by heating can make the food less susceptible to contamination, but it may also cause nutrient losses.
Step-by-step explanation:
Food processing involves different methods, such as heating, which can reduce the susceptibility of the processed food to contamination. When food is heated, it kills or inactivates many microorganisms that may be present. This helps to reduce the risk of foodborne illnesses caused by pathogens. However, it is important to note that some forms of processing, such as high heat, can also cause nutrient losses in the food, which may affect its overall nutritional value.
