| Résumé : |
Animal skin is the basic raw materials for the tanning industry, which is the by-product of meat industry. The degradation of skin starts within several hours after the death of animal if it is left untreated. Application of common salt (sodium chloride, NaCl) is the most popular preservation method of skin; it preserves the skin by its dehydrating ability and bacteriostatic effect. The negative effect of sodium chloride is that it generates a huge amount of pollution in the form of total dissolved solids (TDS) during leather processing. In this present study, an investigation was made to preserve goat skin using plant leaf paste. The preservation process was evaluated by monitoring different parameters e.g., shrinkage temperature, hair slip, putrefaction, odor, moisture content, extractable nitrogen, and bacterial count in comparison to the conventional wet salting method. Results indicate that the leaf paste could be used as curing agents to preserve goat skin. Combination of 10% leaf paste + 10% NaCl could preserve the goat skin for a period of 30 days. In this less-salt preservation method, pollution load was reduced e.g., chlorides and TDS in soaking operation by 45.2% and 49.8%, respectively. |
