Salt used for preservation is discharged along with the soak liquor and contributes to 70% of TDS load from leather manufacturing. As an attempt to reduce chloride and TDS, plant based preservation with Tamarindus indica was studied. Different concentrations of salt and Tamarind leaf extract were applied on freshly-flayed goatskins based on its green weight and compared with control (40% salt alone/kg of skin wt.). Sensory evaluation of the preserved skin was done every day (till 21st day) for smell, hair slip and putrefaction. The samples were collected on 1st, 2nd, 3rd, 71h, 14th and 21st day and tests such as moisture content, total nitrogen content, protein content, hydroxyproline content and microbial load for finding out the curing efficiency. Skin those were preserved for 21 days were processed into leather and the leather and properties were examined. The result showed that 15% salt with 15% Tamarindus indica and 10% salt with 15% Tamarindus indica (Test) showed good preservation systems. Note de contenu : - Skin - Plant extract

Récupération (Déchets, etc.)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : Large quantity of sodium chloride is used for raw skin preservation. Significant amount of salt is removed from raw skin through a mechanical process before taking for further processing in tanneries. This recovered salt is contaminated with various dirt, proteinous materials and microorganisms and gets accumulated, which creates a serious waste disposal problem for tanneries. In this study the recovered contaminated waste salt was purified and reused for skin preservation. The recovered contaminated salt from tannery was dissolved in water, filtered, treated with activated charcoal to remove the undesired components and subjected to ozone treatment for the removal of microbial contamination. The ozonized solution was subjected to solar evaporation. Improved evaporation techniques were employed to facilitate evaporation of salt solution. Dried purified salt obtained was checked for microbial contamination. Then the dry salt was used for the preservation of a fresh batch of animal skin. After a minimum storage period of 21 days, the skins were processed into leather as per the usual procedure and compared with the leathers obtained by conventional fresh salt preserved skins. The physical tests, chemical analysis and organoletic properties of experimental leathers show that the quality of leather obtained from animal skins preserved using purified salt was comparable to leathers obtained from conventional pure salt preserved skins. The approach minimizes salinity concerns of tanning by providing simple and practical solution. Note de contenu : - Materials and methods
