摘要: 以某屠宰加工厂的鸡胴体为实验对象,研究食品中常见的乳酸、丙酸、酒石酸、柠檬酸、葡萄糖酸、山梨酸钾和焦磷酸钠(质量分数均为2%)对鸡胴体雾化喷淋处理后的减菌效果及复合有机酸雾化喷淋处理后对鸡胴体在贮藏期间品质的影响。结果表明:柠檬酸、丙酸和酒石酸对鸡胴体表面的菌落总数和乳酸菌、葡萄球菌属、假单胞菌属、热杀索丝菌、肠杆菌科的减菌效果较好;对柠檬酸、丙酸和酒石酸进行复合喷淋减菌效果研究,确定1%(质量分数,下同)柠檬酸、0.5%丙酸和0.5%酒石酸的复合喷淋减菌效果优于单一有机酸喷淋处理,且复合有机酸喷淋处理后对鸡胴体的红度、黄度和亮度值基本无影响;在11 d的贮藏期内,复合有机酸喷淋处理后鸡胴体的菌落总数、挥发性盐基氮和硫代巴比妥酸反应产物含量都明显降低。因此,复合有机酸雾化喷淋处理对鸡胴体具有明显的减菌效果,并可延长产品的货架期。

Abstract: In this study, the decontamination effects of atomization spraying with lactic acid, propionic acid, tartaric acid, citric acid, gluconic acid, sotassium sorbate or sodium pyrophosphate (2% by mass each) on broiler carcasses from a slaughterhouse were determined together with the influence of organic acid combinations on the quality of broiler carcasses during storage. Results indicated that citric acid, propionic acid and tartaric acid exhibited better efficacy in reducing bacterial counts on broiler carcasses surface including total lactic acid bacteria, Staphylococcus spp., Pseudomonas spp., Brochothrix thermosphacta and Enterobacteriaceae. The combination of 1% citric acid, 0.5% propionic acid and 0.5% tartaric acid was more effective than each alone while having little influence redness (a*), yellowness (b*) and lightness (L*) values. During 11 days of storage, quality indexes such as total plate count, total volatile basic nitrogen (TVB-N) content, thiobarbituric acid reactive substances (TBARS) content were obviously decreased in the combination treatment group. Taken together, combined organic acid treatment has significant decontamination effect on broiler carcasses and thus can be used to prolong the shelf life of the products.
