                                                                  PAPAIN EXTRACTION INDUSTRY

The papaya is the fruit of the papaya tree (Carica papaya) native of Central America.The fruit ripens from 4 to 6 months depending on the climate where it is grown (Salunkhe and Kadam, 1995). The cultivation of this fruit has two main purposes: the sale of the fruit for human consumption and the extraction of enzymes that constitute 40% of the latex in 1 mM concentrations. The papain is a natural proteolytic enzyme that is extracted from the latex in the leaf, the stem and the papaya's unripe fruits. Papain is used in a many industrial fields (like pharmaceutical, brewery, meat, dairy, textile, photographic, optical, tanning, cosmetic, detergents, food and leather industry), because a synthetic enzyme is not capable of simulating the properties of the natural enzyme, which increased its demand. The process to obtain raw papain consists of two main stages: latex extraction and drying. A third stage, purification, may be used if a purified papain is wanted. This work compares the crude enzymatic activity obtained from locally Carica papaya using the unripe fruit and the skin juice under different drying processes and evaluates the enzyme activity for the proposed purification procedure.

     A common enzyme known as papain is obtained from the green papaya (pawpaw) fruit. Enzymes are proteins that can increase the rate of biological changes such as the ripening of fruit. At  the end  of  an  enzyme  catalysed  reaction  the  enzyme  itself  is unchanged and is able to react again.

     Enzymes can be generally recognized by the ending -ase. This either indicates  the nature of the substance  affected  by  the enzyme  (e.g.  carbohydrase  acts on  carbohydrate  material  and proteases  acts  on proteins) or to indicate the  nature  of  the reaction  e.g.  transferases catalyse the transfer  of  atoms  or groups of atoms within a substance.
