Munizyme AN

Acidic bating agent with anti-wrinkling effect. Munizyme AN is a bacterial protease produced by submerged fermentation of a Bacillus Sp. strain especially suitable for wet blue re-bating.

Munizyme AN is an enzyme-based bating agent with an optimum efficiency at a pH range of 3-5.5. it can be used up to temperatures of 55˚C. Its dosage should be around 0.3-0.5% of hide and skin weight. In all cases, it is suggested that Munizyme AN should be evaluated in small scale before going full stream in order to detect its best dosage in the process.

 

Attention: In order to reach the highest activity of this bating agent, it should be used carefully in the pH range of more than 6.5. If Munizyme AN is used in excess amount or time in the mentioned condition, it maybe cause damage in the hides or skins.

Therefore, it is extremely suitable for the application in the pickle process to remove pickle folds and to achieve a clean grain.

Applications & Recommendations

Wet blue can be treated with Munizyme AN to level out the differences of the raw material and to improve the evenness and shade intensification of the dyeing. Also when our wet blue needs extra bating by this agent it is get-at-able.

An acidic bate with Munizyme AN is particularly recommended for wet blue showing a very compact and irregular fiber structure such as calf or goat skins.

It improves the evenness of the leather due to a better opening up of the fibers.

Using of Munizyme AN often expands the cuttable area (yield area) to the normally loose belly area.
