Starch or amylum is a polymeric carbohydrate consisting of numerous glucose units joined by glycosidic bonds. This polysaccharide is produced by most green plants for energy storage. Worldwide, it is the most common carbohydrate in human diets, and is contained in large amounts in staple foods such as wheat, potatoes, maize (corn), rice, and cassava (manioc).
Tapioca is a starch extracted from the tubers of the cassava plant, a species native to the North and Northeast regions of Brazil, but whose use is now spread throughout South America. It is a perennial shrub adapted to the hot conditions of tropical lowlands. Cassava copes better with poor soils than many other food plants.
Marshmallow is a confectionery made from sugar, water and gelatin whipped to a solid-but-soft consistency. It is used as a filling in baking or molded into shapes and coated with corn starch. This sugar confection is inspired by a medicinal confection made from Althaea officinalis, the marsh-mallow plant.
Mochi is a Japanese rice cake made of mochigome (もち米), a short-grain japonica glutinous rice, and sometimes other ingredients such as water, sugar, and cornstarch. The steamed rice is pounded into paste and molded into the desired shape. In Japan, it is traditionally made in a ceremony called mochitsuki. While eaten year-round, mochi is a traditional food for the Japanese New Year, and is commonly sold and eaten during that time.
Cornflour, cornstarch, maize starch, or corn starch is the starch derived from corn (maize) grain. The starch is obtained from the endosperm of the kernel. Corn starch is a common food ingredient, often used to thicken sauces or soups, and to make corn syrup and other sugars. Corn starch is versatile, easily modified, and finds many uses in industry such as adhesives, in paper products, as an anti-sticking agent, and textile manufacturing. It has medical uses as well, such as to supply glucose for people with glycogen storage disease.
Amylose is a polysaccharide made of α-D-glucose units, bonded to each other through α(1→4) glycosidic bonds. It is one of the two components of starch, making up approximately 20–30%. Because of its tightly packed helical structure, amylose is more resistant to digestion than other starch molecules and is therefore an important form of resistant starch.
Amylopectin is a water-insoluble polysaccharide and highly branched polymer of α-glucose units found in plants. It is one of the two components of starch, the other being amylose.
Extrusion is a process used to create objects of a fixed cross-sectional profile by pushing material through a die of the desired cross-section. Its two main advantages over other manufacturing processes are its ability to create very complex cross-sections; and to work materials that are brittle, because the material encounters only compressive and shear stresses. It also creates excellent surface finish and gives considerable freedom of form in the design process.
Kix is an American brand of breakfast cereal introduced in 1937 by the General Mills company of Golden Valley, Minnesota. The product is an extruded, expanded puffed-grain cereal made with cornmeal.
Old Dutch Foods, Inc. is a manufacturer of potato chips and other snack foods in the Midwestern United States, New England and Canada. Their product line includes brands such as Old Dutch Potato Chips, Dutch Crunch, Ripples, Cheese Pleesers and Restaurante Style Tortilla Chips.
Cheese puffs, cheese curls, cheese balls, cheese ball puffs, cheesy puffs, or corn curls are a puffed corn snack, coated with a mixture of cheese or cheese-flavored powders. They are manufactured by extruding heated corn dough through a die that forms the particular shape. They may be ball-shaped, curly, straight, or irregularly shaped. Puffcorn is a similar food, without cheese flavoring.
Puffed grains are grains that have been expanded ("puffed") through processing. They have been made for centuries with the simplest methods like popping popcorn. Modern puffed grains are often created using high temperature, pressure, or extrusion.
The Smith's Snackfood Company is a British-Australian snack food brand owned by the American multinational food, snack, and beverage corporation PepsiCo. It is best known for its brand of potato crisps. The company was founded by Frank Smith and Jim Viney in the United Kingdom in 1920 as Smiths Potato Crisps Ltd, originally packaging a twist of salt with its crisps in greaseproof paper bags which were sold around London. The dominant brand in the UK until the 1960s when Golden Wonder took over with Cheese & Onion, Smith's countered by creating Salt & Vinegar flavour which was launched nationally in 1967.
Puffed rice and popped rice are types of puffed grain made from rice commonly eaten in the traditional cuisines of Southeast Asia, East Asia, and South Asia. It has also been produced commercially in the West since 1904 and is popular in breakfast cereals and other snack foods.
Resistant starch (RS) is starch, including its degradation products, that escapes from digestion in the small intestine of healthy individuals. Resistant starch occurs naturally in foods, but it can also be added as part of dried raw foods, or used as an additive in manufactured foods.
Corn snacks are snack foods made from corn (maize). They are often marketed, packaged and flavoured in a similar way to potato crisps.
Mouthfeel refers to the physical sensations in the mouth caused by food or drink, making it distinct from taste. It is a fundamental sensory attribute which, along with taste and smell, determines the overall flavor of a food item. Mouthfeel is also sometimes referred to as texture.
Extrusion in food processing consists of forcing soft mixed ingredients through an opening in a perforated plate or die designed to produce the required shape. The extruded food is then cut to a specific size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate. The extruder is typically a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.
Mian Nadeem Riaz is a Pakistani–American food scientist, academic and author. He is a professor in food diversity, director of the Extrusion Technology Program and the Associate Department head of the Food Science and Technology Department at Texas A&M University.
