| Résumé : |
Chilling is considered an alternative curing method for salt-free short-term preservation of hides and skins, but no systematic studies has been carried out with this method. In the present study, an attempt was made to investigate the role of chilling temperatures on the preservation efficacy. The experiments were done in a cold temperature cabinet using goat skins and cow hides. The samples of the hides and skins, chilled to different temperatures, were analyzed for the bacterial count, soluble nitrogen and hydroxyproline. The data suggested that 4oC is the optimum temperature for 7 days storage. The results of the chilling profile study indicate the need for a blast chiller to chill down to the target temperature in less than 2 hours in order to minimize the chance for bacterial damage. The optical microscopic studies of the chilled hides and skins at different temperatures show that the fiber compaction increases with the decrease in temperature compared to the skins preserved with common salt. The leathers produced had also the required qualities and strength properties to fulfill the trade requirements as evidenced from the organoleptic assessment, physical testing and scanning electron microscopic studies. |
