肉鸡屠宰加工过程中的微生物控制对保障食品安全和人类健康具有重要意义。肉鸡屠宰加工过程中,浸烫、洗涤、冷却是微生物污染控制的重要环节,多种措施的联合使用可有效降低肉鸡胴体中微生物载量。其中次氯酸钠、氯化十六烷基吡啶、酸化亚氯酸钠等抗菌剂可有效减少肉鸡胴体中沙门菌、大肠埃希菌和弯曲菌等致病菌污染,但不同减菌环节及抗菌剂的使用剂量、作用时间等对减菌效果影响较大。本文综述了肉鸡屠宰加工过程中各环节微生物污染的控制措施,同时也对多种抗菌剂在上述工艺环节中的减菌效果进行系统阐述,以期为国内肉鸡屠宰加过程中微生物污染防控提供数据参考,促进肉鸡生产行业健康发展,保护消费者健康。 相似文献

Food contamination with heat‐resistant fungi (HRF), and their spores, is a major issue among fruit processors, being frequently found in fruit juices and concentrates, among other products, leading to considerable economic losses and food safety issues. Several strategies were developed to minimize the contamination with HRF, with improvements from harvesting to the final product, including sanitizers and new processing techniques. Considering consumers’ demands for minimally processed, fresh‐like food products, nonthermal food‐processing technologies, such as high‐pressure processing (HPP), among others, are emerging as alternatives to the conventional thermal processing techniques. As no heat is applied to foods, vitamins, proteins, aromas, and taste are better kept when compared to thermal processes. Nevertheless, HPP is only able to destroy pathogenic and spoilage vegetative microorganisms to levels of pertinence for food safety, while bacterial spores remain. Regarding HRF spores (both ascospores and conidiospores), these seem to be more pressure‐sensible than bacterial spores, despite a few cases, such as the ascospores of Byssochlamys spp., Neosartorya spp., and Talaromyces spp. that are resistant to high pressures and high temperatures, requiring the combination of both variables to be inactivated. This review aims to cover the literature available concerning the effects of HPP at room‐like temperatures, and its combination with high temperatures, and high‐pressure cycling, to inactivate fungi spores, including the main factors affecting spores’ resistance to high‐pressure, such as pH, water activity, nutritional composition of the food matrix and ascospore age, as well as the changes in the spore ultrastructure, and the parameters to consider regarding their inactivation by HPP. 相似文献

There is an increasing need for rapid test methods to certify the quality and safety of food products. Current tests applied for the microbiological assessment of food products are based on standard approved culture-based isolation methods and can take several days to yield results. Nucleic acid diagnostic (NAD) tests for the identification of bacterial foodborne pathogens employing in vitro amplification technologies are capable of sensitive and specific detection of single or multiple pathogens in foods in a shorter timeframe than traditional methods. New developments in molecular biosensors have the potential to provide at-line bioanalysis, whereas microarray-based technologies may in the future be the NAD platforms of choice for multiple pathogen detection and identification. This article reviews current and emerging NAD platforms for foodborne bacterial pathogens that have the potential to impact food safety. 相似文献

Biofilm is an advanced form of protection that allows bacterial cells to withstand adverse environmental conditions. The complex structure of biofilm results from genetic-related mechanisms besides other factors such as bacterial morphology or substratum properties. Inhibition of biofilm formation of harmful bacteria (spoilage and pathogenic bacteria) is a critical task in the food industry because of the enhanced resistance of biofilm bacteria to stress, such as cleaning and disinfection methods traditionally used in food processing plants, and the increased food safety risks threatening consumer health caused by recurrent contamination and rapid deterioration of food by biofilm cells. Therefore, it is urgent to find methods and strategies for effectively combating bacterial biofilm formation and eradicating mature biofilms. Innovative and promising approaches to control bacteria and their biofilms are emerging. These new approaches range from methods based on natural ingredients to the use of nanoparticles. This literature review aims to describe the efficacy of these strategies and provide an overview of recent promising biofilm control technologies in the food processing sector. 相似文献

非热杀菌技术在低温鸡肉制品致病菌控制中的应用研究进展 总被引:1,自引:0,他引:1
由于低温鸡肉制品具有较好的感官品质,能够保留鸡肉原有的营养,成为我国肉制品发展的一个趋势。低温鸡肉制品水分含量和pH值较高,在加工和贮藏过程中极易受到食源性致病菌的污染,影响产品的质量安全,甚至引发食源性疾病,因此采用合适的杀菌技术来解决致病菌的污染是低温鸡肉制品贮藏保鲜需要解决的关键问题。由于热杀菌技术不适合用于低温鸡肉制品的灭菌,非热杀菌技术的应用就显得尤其重要。目前,应用在低温鸡肉制品加工中的非热杀菌技术主要包括超高压、辐照、超声、低温等离子体、脉冲紫外线、脉冲电场和脉冲微波。本文主要综述以上7 种非热杀菌技术的杀菌机制以及在不同低温鸡肉制品加工应用时对致病菌的控制效果,为未来非热杀菌技术在低温肉制品加工中的应用提供参考。 相似文献

Consumers demand, in addition to excellent eating quality, high standards of safety and nutrition in ready-to-eat food. This
requires a continuous improvement in conventional processing technologies and the development of new alternatives. Prevailing
technologies such as thermal processing can cause extensive and undesirable chemical changes in food composition while minimal
processing strategies cannot eliminate all microbial pathogens. This review focuses on pressure-assisted thermal processing,
a new alternative for shelf-stable foods. Its implementation requires an analysis of reaction kinetics at high pressure and
elevated temperature. Acceleration of the inactivation of bacterial spores by the synergistic effect of pressure and temperature
is expected to allow processing at lower temperature, shorter process time, or a combination of both. Therefore, thermal degradation
of quality is expected to be lower than that of conventional thermal processes. However, few studies have focused on the effect
of the conditions required for the inactivation of bacterial spores on the kinetics of chemical reactions degrading food quality,
particularly at the high temperatures required for the processing of low-acid foods. 相似文献
