The conventional extraction methods of phenolic compounds from fruits and vegetables have some limitations such as high solvent consumption, long extraction time, low yield, and low quality of the extracts due to long . Several drugs can extract by only maceration methods due to their high swelling property or high mucilage content. The maceration process is nothing more than an extraction process between materials of different physical solid-liquid states, in which the chemical compounds of interest are found in the solid matter, since they have solubility; a liquid is used that allows its extraction. It consists of immersing a plant in a liquid (water, oil, alcohol, etc.) it may be defined as the treatment of the plant or animal tissues with appropriate solvent, which would dissolve the medicinally active constituents. The main difference between maceration and percolation is that the maceration is a process of soaking something to make it softer whereas the percolation is the seepage or filtration of a liquid through a porous substance.

The stirring in the extraction process helps to increase the diffusion of tannins into the extract. This is an extraction procedure in which coarsely powdered drug material, either leaves or stem bark or root bark, is placed inside a container; the menstruum is poured on top until completely covered the drug material. This cold soak pulls out brighter fruit and darker color than regular maceration. . Skin maceration, or pruning, is the softening and breaking down of skin from being exposed to too much moisture.

Maceration is the process by which organized tissue is transformed into a suspension of intact cells, resulting in pulpy products used as base material for pulpy juices and nectars, as baby foods, and as ingredients for dairy products such as puddings and yoghurts (Pilnik and Voragen, 1993; Khatri et al., 2015).

The malting process is to place the barley within natural water for a period of two to three days.
