The best results or quality indicators at the optimum temperature (6 ☌) and time (3 h) were viscosity (90 cp), moisture content (14.6%), ash content (2.23%), density (1259 kg/m 3), yield (32 g glue/100 g of hide), PH (5.98), water solubility by color (black), and shear strength (260 MN). Then the glue was cooled and characterized and best results were obtained at a temperature of 6 ☌ and at time of 3 h. The filtered glue solution was concentrated in rotary vacuum evaporator. After extraction the solution was filtered with nylon cloth to separate the non collageneous materials. The extraction processes were taken place at temperature of 60, 65 & 70 ☌ and the time of 2.5, 3 & 3.5 h in water bath. The hide trimming waste after pretreatment were soaked for 4 h in lime solution and washed with water and followed by neutralized by hydrochloric acid. In this research parameter that were studied are pretreatment and conditioning techniques during animal glue production. The main raw material used for the study is hide trimming waste from Bahir Dar tannery plc. Animal glue is the most important protein adhesive obtained from animal hides, skins, and bones through hydrolysis of the collagen. ![]()
