FOOD CHEMISTRY INTRODUCTION: Food chemistry is the study of the chemical process and interactions that occur within food. It encompasses the understanding of the composition, structure, and properties of food substances and how these factors effect taste, texture, nutritional value, and safety. Nutritional concepts: Food is primarily composed of macro nutrients (carbohydrates, proteins, and fats) and micronutrients (vitamins and minerals). Each plays a vital role in human health. Flavor and Aroma: Chemical compounds such as esters, aldehydes, and terpenes contribute to the flavor and aroma of food processing and flavor enhancement.
