Food preservation includes processes that make food more resistant to microorganism growth and slow the oxidation of fats. This slows down the decomposition and rancidification process. Food preservation may also include processes that inhibit visual deterioration, such as the enzymatic browning reaction in apples after they are cut during food ...
Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [a] although under specific circumstances, it can be much longer. [2] A freeze-dried canned product, such as canned ...
Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of salt, with the aim of drawing moisture out of the food by the process of osmosis. Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable ...
Individual quick freezing, usually abbreviated IQF, is a descriptive term for freezing methods used in the food processing industry. The food is in individual pieces, and is frozen quickly. Products commonly frozen with IQF technologies are typically smaller pieces of food, and can include berries, fruits and vegetables both diced or sliced ...
Dry pasta manufacturing line from 1930s. The first extruder was designed to manufacture sausages in the 1870s. [4] Dry pasta and breakfast cereals have been produced by extrusion since the 1930s, [2] and the method has been applied to tater tots (first extruded potato product: Ore-Ida in 1953) and pet food production since the 1950s (first extruded dog food: Purina Dog Chow in 1957, and first ...
How-to knead dough. In cooking (and more specifically baking), kneading is a process in the making of bread or dough, used to mix the ingredients and add strength to the final product. It allows the process of baking to be shortened by developing the gluten more quickly than it would develop in the absence of kneading. [1]
Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. In accordance with the internationally established definition, freezing means the solidification phase change of a liquid or the liquid content of a substance, usually due to cooling. [ 1 ][ 2 ] For most substances, the ...
Parchment paper, also known as baking paper, is a cellulose -based paper whose material has been processed so as to obtain additional properties such as non-stickiness, grease resistance, resistance to humidity and heat resistance. [1][2] It is commonly used in baking and cooking as a disposable non-stick paper.
