Study of chemical processes and interactions of all biological and non-biological components of foods
Food chemistry is the study of chemical processes and interactions of all biological and non-biological components of food. It is similar to biochemistry in its main components such as carbohydrates, lipids, and proteins, but it also includes areas such as water, vitamins, minerals, enzymes, food additives, flavors, and colors. This discipline also encompasses how products change under certain food processing techniques and ways either to enhance or to prevent them from happening.
Carbohydrates[edit]
Carbohydrates are one of the most important components of food, providing energy through their oxidation. They are classified into monosaccharides, disaccharides, and polysaccharides. Monosaccharides, such as glucose and fructose, are the simplest form of carbohydrates. Disaccharides, such as sucrose (saccharose), consist of two monosaccharide units. Polysaccharides, such as starch and cellulose, are complex carbohydrates composed of long chains of monosaccharide units.
Proteins[edit]
Proteins are large biomolecules consisting of one or more long chains of amino acids. They play a crucial role in the structure and function of all living cells and viruses. Proteins are essential in the diet of humans and animals, providing the necessary amino acids that the body cannot synthesize on its own. The structure of proteins can be affected by denaturation, which can occur through heat, pH changes, or other chemical interactions.
Lipids[edit]
Lipids are a diverse group of compounds that are insoluble in water but soluble in organic solvents. They include fats, oils, waxes, and steroids. Lipids are an important source of energy and are essential for the absorption of fat-soluble vitamins. They also play a key role in the structure of cell membranes.
Vitamins and Minerals[edit]
Vitamins are organic compounds that are essential in small amounts for the normal functioning of the body. They are classified into water-soluble and fat-soluble vitamins. Riboflavin (vitamin B2) is an example of a water-soluble vitamin that is important for energy production and the metabolism of fats, drugs, and steroids.
Minerals are inorganic elements that are also essential for the body. They play a variety of roles, including building strong bones and teeth, controlling body fluids inside and outside cells, and turning the food you eat into energy.
Enzymes[edit]
Enzymes are biological molecules that act as catalysts and help complex reactions occur everywhere in life. In food chemistry, enzymes are important for the breakdown of food components, such as the conversion of starches into sugars by amylase, or the breakdown of proteins by proteases.
Food Additives[edit]
Food additives are substances added to food to preserve flavor or enhance its taste, appearance, or other qualities. Common food additives include preservatives, colorants, flavor enhancers, and emulsifiers. The use of food additives is strictly regulated by health authorities to ensure safety.
Flavors and Colors[edit]
Flavors are the sensory impressions of food or other substances, and they are determined mainly by the chemical senses of taste and smell. Colors in food can be natural or artificial, and they play a significant role in the appeal and acceptability of food products.
