Comprehension Passage
Food processing encompasses a wide array of practices aimed at transforming raw ingredients into consumable products or altering the form of existing food items for better preservation, taste, and convenience. At the heart of food processing is the crucial step of preservation, designed to inhibit the activity of microorganisms such as bacteria, fungi, and others responsible for food spoilage. Ancient preservation techniques grounded in human ingenuity involve methods like sun-drying, chilling in natural ice or cold water, and fermenting with microorganisms for flavour and longevity. On the other hand, contemporary advancements in food science have introduced methods like thermal processing, quick-freezing, high-pressure pasteurization, electromagnetic radiation, and the strategic use of preservatives to maintain or even enhance the food's safety, nutritional value, and shelf life.
