Maceration continues during the fermentation period, and can last well past the point when the yeast has converted all sugars into alcohol. The process itself is a slow one with compounds such as the anthocyanins needing to pass through the cell membrane of the skins to come into contact with the wine.
Maceration of dried fruit in rum and apple juice. Maceration is the process of preparing foods through the softening or breaking into pieces using a liquid. Raw, dried or preserved fruit or vegetables are soaked in a liquid to soften the food, or absorb the flavor of the liquid into the food. [1]
Vanilla extract in a clear glass vial. Vanilla extract is a solution made by macerating and percolating vanilla pods in a solution of ethanol and water.It is considered an essential ingredient in many Western desserts, especially baked goods like cakes, cookies, brownies, and cupcakes, as well as custards, ice creams, and puddings.

Maceration (bone), a method of preparing bones; Acid maceration, the use of an acid to extract micro-fossils from rock; Maceration, in chemistry, the preparation of an extract by solvent extraction; Maceration, in biology, the mechanical breakdown of ingested food into chyme; Skin maceration, in dermatology, the softening and whitening of skin ...
The natural occurrence of fermentation means it was probably first observed long ago by humans. [3] The earliest uses of the word "fermentation" in relation to winemaking was in reference to the apparent "boiling" within the must that came from the anaerobic reaction of the yeast to the sugars in the grape juice and the release of carbon dioxide.
However, the co-product from this process will produce corn oil, corn gluten meal, corn germ meal, corn gluten and feed steep water. The average of one bushel of corn generally will have about 32 lb of starch or 33 lb sweeteners or 2.5 gallons of fuel ethanol and 11.4 lb gluten feed and 3 lb gluten meal and 1.6 lb corn oil.

Carbonic maceration techniques (e.g. semi-carbonic maceration) have recently been adapted to coffee processing. The ripe coffee cherries are placed inside a hermetic stainless steel tank and left to undergo an anaerobic fermentation. This fermentation process brings out intense aromas, with a taste profile akin to red wine and whisky.
Industrial fermentation is the intentional use of fermentation in manufacturing processes. In addition to the mass production of fermented foods and drinks, industrial fermentation has widespread applications in chemical industry. Commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation. [1]
