The tanning industry is burdened with substantial environmental concerns, especially due to hazardous chemicals used in dehairing and chrome tanning processes. This research investigates the application of indigenous microorganisms (IMO) derived from rumen fluid, integrated with gambier-based vegetable tanning, to create an eco-friendly dehairing method for goat hides while examining its effects on their physicochemical and sensory characteristics.
Dehairing goat leather using enzymes from IMO of rumen fluid is an environmentally friendly alternative. This study evaluated the impact of rumen liquid IMO on the dehairing process of gambier goat leather and its physicochemical and sensory properties.
This study used 20 pieces of goat leather and rumen liquid. This study used an experimental method with a completely randomized design, five treatments, and four replications. The treatments included soaking the skin in rumen liquid IMO for 0-4 days and adding 6% lime.
The results showed that the use of rumen fluid IMO in the dehairing process significantly affected ( < 0.05) the tensile strength, elongation, rawhide substance, degree of tanning, water-soluble substances, and sensory value. Nonetheless, they exerted no substantial impact (p > 0.05) on Zwik strength, moisture, fat, bound tannin, and ash content.
The best treatment in terms of physicochemical and sensory properties on goat skin is soaking for three days in rumen fluid IMO, with the following characteristics: the meat part is clean from meat residue, the skin condition is quite soft, the skin color is yellowish brown, and the skin surface is smooth, where the test meets the SNI quality standards of 06-0463-1989.
制革行业面临着重大的环境问题，尤其是在脱毛和铬鞣工艺中使用的有害化学物质。本研究调查了源自瘤胃液的本土微生物（IMO）与藤黄属植物鞣制相结合的应用，以创建一种用于山羊皮的环保脱毛方法，同时研究其对山羊皮物理化学和感官特性的影响。
使用瘤胃液中IMO的酶对山羊皮进行脱毛是一种环保的替代方法。本研究评估了瘤胃液IMO对藤黄山羊皮脱毛过程及其物理化学和感官特性的影响。
本研究使用了20块山羊皮和瘤胃液。本研究采用完全随机设计的实验方法，设置5种处理，每种处理重复4次。处理方法包括将山羊皮在瘤胃液IMO中浸泡0至4天，并添加6%的石灰。
结果表明，在脱毛过程中使用瘤胃液IMO对拉伸强度、伸长率、生皮物质、鞣制程度、水溶性物质和感官价值有显著影响（<0.05）。然而，它们对Zwik强度、水分、脂肪、结合单宁和灰分含量没有实质性影响（p>0.05）。
就山羊皮的物理化学和感官特性而言，最佳处理方法是在瘤胃液IMO中浸泡三天，其特点如下：肉面无肉渣残留，皮的状态相当柔软，皮色为黄褐色，皮表面光滑，该测试符合SNI 06 - 0463 - 1989质量标准。
