| Résumé : |
Bovine raw hides are commercially cured either with high salt concentration of about half the weight of actual hide or 95% saturated brine solution. This conventional technique is very popular due to the availability of common salt (sodium chloride) and its cost-effective procedure but it generates a huge pollution problem increasing salinity. As a result, an alternative method of using less or no salt for hide preservation needs to be developed. For the preservation of hide it is essential to arrest microbial attack on hide as the main constituent of raw hide is protein which is very susceptible for bacterial degradation. Such bacterial degradation leads to the putrefaction of raw hide before converting them into leather. Agricultural Research Services scientists at Wyndmoor, Pennsylvania, have developed antiseptic based formulations for hide curing where only 45% saturated brine solution is used. The newly developed formulations have been found more effective in limiting microbial growth for a longer time on cured skin than the regular brine process and thus preserve hides for more than 30 days. In-process analysis of cured hides during storage period reveals the compatibility of the alternative curing process in comparison to the traditional method. Therefore, this new development will not only preserve hide through better protection from microorganisms but also offers improved conservation of the environment. |
