[17] Disruption: Known in the Western tea industry as disruption or leaf maceration, the teas are bruised or torn in order to promote and quicken oxidation. [18]
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 that is kept constantly wet; Maceration, in poultry farming, a method of chick culling
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]
