| Résumé : |
A matched side experiment was carried out to corroborate small scale studies on the effectiveness of an acidified sulfite solution" as a short-term preservation system for fresh hides.
One side of each hide was conventionally sait cured and the other was treated with a 20 percent float containing 1.5 percent sodium sulfite and one percent acetic acid (on hide weight). Using six matched sides for each storage period, the sides were held six, 14, and 28 days at ambient temperatures. The leathers prepared from the preserved hides were tested for tensile strength, suitabilitv for lasting, and shrinkage temperature. The preservation was also monitored hy using microbial counts and noting the odor of the bides. The leathers made from sides held for all three storage periods were considered commercially acceptable. The results demonstrated that acidified sulfite provides an alternative to salt curing for the short-term preservation of hides. The new method reduces the dissolved solids in tannery effluents, an identified pollution problern caused hy the use of salt cured hides. In addition, the reduction of the microbial load in the preserved bides provides more sanitary conditions for hide handling. |
