Physicochemical and sensory characteristics of sheep and goat cured legs were evaluated. The pH values (5.7-5.8) and aw (0.87 and 0.83) found to be adequate to control meat deterioration, promoting safety and stability to shelf life of products with respect to microbial growth. The high protein (46.2 and 38.4%) and low fat (5.3 and 8.7%) percentages of the goat and sheep cured legs were the main evidence of the effect of salting and ripening processes. A low cholesterol content of 4.5% is particularly evident in sheep cured legs. Curing process produced a slight increase in the P/S ratio 0.23 and 0.17 for goat and sheep cured legs, respectively. TBARS values are much lower than the value of 2mg of MDA/Kg which is the upper limit of rancidity. Physico-chemical and sensory characteristics indicate that producing cured goat and sheep legs from cull animals can be an interesting way of adding value to animals with very low commercial prices.
对绵羊和山羊腌制腿的理化和感官特性进行了评估。发现 pH 值(5.7-5.8)和水分活度(0.87 和 0.83)足以控制肉的变质,促进了产品微生物生长的安全性和稳定性,以延长保质期。山羊和绵羊腌制腿的高蛋白质(46.2%和38.4%)和低脂肪(5.3%和8.7%)百分比是腌制和成熟过程影响的主要证据。绵羊腌制腿的胆固醇含量特别低,为 4.5%。腌制过程使 P/S 比分别增加了 0.23 和 0.17,山羊和绵羊腌制腿的 P/S 比分别为 0.23 和 0.17。TBARS 值远低于 2mg MDA/kg 的上限,这是酸败的上限。理化和感官特性表明,用淘汰动物生产山羊和绵羊腌制腿,可以为价格非常低的动物增加附加值的一种有趣方式。
