Classification is the process of grouping items either living or non-living, according to their similarity in nature as well as character. It helps people by making it easier to search for items without having to scroll in the list or fields. Food classification in a store makes it easier to issue, order and control their usage. Foods can be classified into two broad categories, i.e., plant origin and animal origin. Plant origin can be sub-divided into categories such as cereals and legumes, vegetables, fruits, spices and herbs, as well as nuts and seeds. Animal origin includes terrestrial mammals, aquatic animals, poultry and bee products.
Vegetables are edible plants or their parts, i.e., leaves, roots or stem. Vegetables are either consumed raw or cooked. However, some must be cooked for them to be edible. Examples of vegetables include potatoes, sugarcane, turnips, horseradish, cabbages, cauliflower, artichoke, tomatoes, carrots, etc. All these examples come from stem, root or leaves.
Cereals can be defined as grasses that are cultivated for their edible grains. They are grown in large quantities to provide food worldwide and, therefore, they are stable crops. Examples of cereals include rice, wheat, barley, rye, corn, etc. Legumes are dry one-celled fruits, which develop from simple ovary to become pods. The seeds are attached to one edge of the valves that make a pod. Such legumes include beans, peas, peanuts, soybeans, etc. All the examples are pods that contain seeds inside and both the pod and seeds are used as food.
Spices are dried seeds, fruits, leaf or bark used in small quantities as food additives to add flavor, color or preserve food. Herbs are leafy plant parts, which are green and used for flavoring purposes. Examples of spices include paprika, ginger, rhizomes, garlic, etc. Those of herbs include parsley, celery, peppermint, spearmint, etc. All these examples are basically used for flavoring food.
Fruits are fleshy structures, which are sweet and edible in their raw state. They come from certain plants and are seed-associated. Examples include apples, grapes, oranges, strawberries, bananas, juniper berries, etc. All these examples are edible in their raw state and are seed-associated.
Seeds and nuts are foods common in diets and are often eaten as snacks. They are included in vegetarian dishes as staples in place of meats. They are nutrient-dense and provide protein, fiber, enzymes, healthy fats, vitamins as well as minerals. Examples of nuts and seeds include sunflower seeds, almond, cotton seeds, chestnut, walnut, etc. These examples are used in place of meat as well as snacks.
Terrestrial mammals are animals, which live entirely or predominantly on land. Their carcass is edible and it produces liver, fats, muscles, kidney, and offal. Examples of mammals include sheep, goat, pig, cattle, horse, and deer. All these animals provide fats, muscles, liver, offal and kidney when slaughtered.
Poultry is a term used to refer to the domesticated birds, which are kept by people for purposes of eggs, meat and feathers. They provide meat, eggs, fat, muscles, liver, kidney and offal. Examples of poultry include chicken, duck, and turkey. These poultry are kept for their eggs, meat, offal, kidney and fat.
Aquatic animals are either invertebrate or vertebrate animals that live in water. They breathe air or extract oxygen from water through their special organs called gills. Examples include salmon, trout, globe-fish, bream, crustaceans, shelled mollusks, etc. all of them live in water and have gills for breathing.
Bee products are substances produced by honeybee and consumed as nutritional or food supplements. They are packed with minerals, vitamins and essential amino acids. Examples include honey, bee propolis and bee pollen. These examples are produced by bees and stored in beehives.
