उत्तर
The method of preservation depends on moisture content of the food and shelf life of the food.
Explanation:
Different foods have completely different physical structures, chemical compositions, pH levels, and nutrient profiles. Therefore, the choice of preservation technique is dictated primarily by what the food item actually is. For instance, milk requires pasteurisation or boiling, meat and fish are often salted, smoked, or frozen, while fruits and vegetables are commonly preserved through canning, pickling, or drying.
