Abstract

Dead on arrival (DOA) animals, particularly poultry, refer to animals that die during the pre-slaughter phase and are generally considered waste, despite their potential as raw materials for leather production. However, scientific information regarding the quality of leather produced from DOA chicken feet skin remains limited. Therefore, this study aimed to evaluate the feasibility of utilizing DOA chicken feet skin by comparing its physical and chemical properties with those of fresh chicken feet skin after tanning. Chicken feet skin from both sources was processed through beamhouse operations, tanning, post-tanning, and finishing stages before quality evaluation. Physical properties analyzed included thickness, softness, shrinkage temperature, elasticity, tensile strength, tear strength, and seam strength, while chemical properties included pH, moisture content, and oil/fat content. Differences between treatments were analyzed using an independent samples t-test for parameters with sufficient replicates. The results showed that thickness, softness, and shrinkage temperature were not significantly different (P>0.05). Fresh and DOA leather showed comparable seam strength values of 602.52 N/cm and 600.23 N/cm, respectively. Chemical properties were also similar, with pH of 4, moisture contents of 15.16% and 13.82%, and oil/fat contents of 14.94% and 14.05%. Overall, DOA chicken feet skin showed comparable characteristics and potential for leather production.

Abstract

Objective: This study aims to examine the physical structure of goat skins tanned with aluminium as an alternative tanning agent.Methods: Twelve pieces of goat skin from the pikle breed were used in the study. Chromosal B, an aluminium tanning agent, Novaltan Al, salt (NaCl), Derminol OCS, MgO, Sodium bicarbonate, a BCG indicator, Permit MLN, and an anti-fungal are among the chemicals utilized. The approach involves tanning using chrome tanning as a control and aluminum tanning with amounts of 2%, 4%, and 6% Al2O3. Cross-sectional tests were used to assess the wet white leather's results, and the SEM-EDX method was used to determine the leather's composition.Results: Leather tanned with aluminium tanning agent shows the distribution of aluminium in the skin section, the increasing use of aluminium tanning materials, the higher the aluminium content in tanned leather.Conclusions: The presence of aluminium tanning agent in the skin indicates an interaction between the material and the skin so that it can be used as an alternative tanning agent.
