| Papain Usage And Synthesis |
| Chemical Properties | cream to light brown powder |
| Uses | Papain may cause allergic manifestation .Person handling this material should be protected against inhalation of dust and contact with the skin or eyes. |
| Uses | papain is a papaya enzyme able to dissolve keratin. Papain is used in face masks and peeling lotions as a very gentle exfoliant. It can be irritating to the skin but less so than bromelin, a similar enzyme found in pineapples and also used in cosmetics. It is considered a non-comedogenic raw material. |
| Uses | Papain is a tenderizer that is a protein-digesting enzyme obtained from the papaya fruit. the enzyme, used in a patented process, is injected into the circulatory system of the live animal and is activated by the heat of cooking to break down the protein, thus tenderizing the beef. the enzyme is inactivated by stomach acids. |
| Uses | For tenderizing meats; for clearing beverages; for bating skins. |
| Brand name | Caroid (Sterling Winthrop). |
| Safety Profile | Poison by intraperitoneal route. Human systemic effects by ingestion: changes in structure or function of esophagus. Experimental teratogenic and reproductive effects. An allergen. When heated to decomposition it emits toxic fumes of NOx. |
| Purification Methods |
A suspension of 50g of papain (freshly ground in a mortar) in 200mL of cold water is stirred at 4o for 4hours, then filtered through a Whatman No 1 filter paper. The clear yellow filtrate is cooled in an ice-bath while a rapid stream of H2S is passed through it for 3hours, and the suspension is centrifuged at 2000rpm for 20minutes. Sufficient cold MeOH is added slowly with stirring to the supernatant to give a final MeOH concentration of 70 vol%. The precipitate, collected by centrifugation for 20minutes at 2000rpm, is then dissolved in 200mL of cold water, the solution is saturated with H2S, centrifuged, and the enzyme is again precipitated with MeOH. The process is repeated four times. [Bennett & Niemann J Am Chem Soc 72 1798 1950.] Papain has also been purified by affinity chromatography on a column of GlyGlyTyrArg-agarose [Stewart et al. J Am Chem Soc 109 3480 1986]. |
