1. Dehydration: One way to remove water from food is through dehydration. This can be done by exposing the food to heat, such as through baking, roasting, or drying. By removing the water content, bacteria are unable to grow and reproduce, as they require moisture to survive. Dehydrated foods have a longer shelf life and are less prone to bacterial contamination.
2. Freezing: Another method to remove water from food is by freezing. When food is frozen, the water content turns into ice, preventing bacterial growth and reproduction. Freezing also slows down the enzymatic activity in food, which further inhibits bacterial growth. By storing food at freezing temperatures, bacteria are unable to multiply, ensuring the food remains safe for consumption for an extended period.
