酱卤肉制品作为我国传统熟肉类制品,因其自身性质及加工特性,极易遭受微生物污染.该研究对酱卤类产品在不同加工阶段的污染状况进行检测,从而找出引起产品微生物污染的关键环节及主要因素.结果显示,酱卤类产品从卤煮到包装环节微生物数量呈上升趋势,对各产品进行多样性分析,发现各产品间存在差异,烧鸡、猪头肉、鸭脖在冷却前期优势菌属分别为不动杆菌属(Acinetobacter,38.93％)、链球菌属(Streptococcus,19.38％)和金黄杆菌属(Chryseobacterium,63.26％),包装后期分别转变为不动杆菌属(Acinetobacter,39.70％)、魏斯氏菌属(Weissella,38.25％)和肠杆菌属(Enterobacter,57.92％).对其加工环境进行溯源,发现卤煮车间的温度最高为(22.38±2.24)℃,且微生物污染也最严重,最高达(75.67±9.07)CFU/皿,推车、挡板、盛样筐等接触器械为主要污染点,是造成产品微生物污染的主要因素.该研究结果可为酱卤肉制品加工安全防控提供科学理论依据.
Change and Traceability of Microbial Diversity of Different Marinated Meat Products During Processing
As traditional cooked meat products in China,marinated meat products are highly susceptible to microbial contamination due to their inherent properties and processing characteristics.In this study,the contamination status of marinated products at different processing stages is detected,so as to identify the key links and main factors causing microbial contamination in the products.The results show that the number of microorganisms in marinated meat products shows an upward trend from boiling to packaging.The diversity analysis of various products is carried out,it is found that there are differences among various products,and in the early stage of cooling,the dominant bacterial genera of roasted chicken,pig head meat and duck neck are Acinetobacter(38.93％),Streptococcus(19.38％)and Chryseobacterium(63.26％)respectively,and the dominant bacterial genera change to Acinetobacter(39.70％),Weissella(38.25％)and Enterobacter(57.92％)respectively in the later stage of packaging.The processing environment is traced,it is found that the temperature of the cooking workshop is the highest of(22.38±2.24)℃,and the microbial contamination is the most severe,which is up to(75.67±9.07)CFU/vessel.The contact devices such as carts,baffles and sample baskets are the main pollution points,which are the main factors causing microbial contamination of products.This study results can provide a scientific theoretical basis for the safety prevention and control of the processing of marinated meat products.
