Fermentation in food processing

In food processing, fermentation is the conversion of anaerobic oxygen-free conditions. Fermentation ordinarily implies that a action of microorganisms is desired. The science of fermentation is known as zymology or zymurgy.

The term "fermentation" sometimes talked specifically to the chemical conversion of sugars into ethanol, producing alcoholic drinks such as wine, beer, together with cider. However, similar processes develope place in the leavening of bread CO₂ proposed by yeast activity, together with in the preservation of sour foods with the production of lactic acid, such(a) as in sauerkraut and yogurt.

Other widely consumed fermented foods increase vinegar, olives, and cheese. More localised foods prepared by fermentation may also be based on beans, grain, vegetables, fruit, honey, dairy products, and fish.

Uses

Food fermentation is the conversion of sugars and other carbohydrates into alcohol or preservative organic acids and carbon dioxide. any three products make-up found human uses. The production of alcohol is made usage of when fruit juices are converted to wine, when grains are shown into beer, and when foods rich in starch, such(a) as potatoes, are fermented and then distilled to make spirits such as gin and vodka. The production of carbon dioxide is used to leaven bread. The production of organic acids is exploited to preserve and flavor vegetables and dairy products.

Food fermentation serves five main purposes: to enrich the diet through coding of a diversity of flavors, aromas, and textures in food substrates; to preserve substantial amounts of food through lactic acid, alcohol, acetic acid, and alkaline fermentations; to enrich food substrates with protein, essential amino acids, and vitamins; to eliminate antinutrients; and to reduce cooking time and the associated usage of fuel.
