EVALUATION OF THE EFFECTIVENESS OF DIFFERENT ENZYME FORMULATIONS IN THE UNHAIRING PROCESS OF GOATSKINS

Due to the high levels of pollution load produced in leather industry, many studies are being conducted replace most hazardous chemicals used. One options is use enzymes which biodegradable and considered environmentally friendly. Hides skins contain non-collagenous substances that require specific remove. The aim study was evaluate effectiveness different enzyme formulations unhairing process goatskins. To achieve this, four types were purchased from Jian Grace Industries include amylase (100,000 U/g), protease (200,000 keratinase lipase U/g). All possible combinations one, two, three per formulation prepared by mixing equal amounts formulation. Parameters such as total solids, dissolved solids protein content determined on affluent standard procedures. In addition, percentage weight gain, residual fat organoleptic test pelt evaluated. Data analysed using SPSS statistical packages version 21. ANOVA t-test used level significance (p≤ 0.05). Although several gave complete unhairing, a keratinase, protease, (KPL) selected best This completely unhaired with 6.4%. tests all pelts had rating 7-9. conclusion, application more than one can be better option removing components replacement sodium sulphide process.
