近年来,超声波因具有绿色、无残留等优势,成为非热加工技术领域的研究热点之一,且在杀菌领域也逐渐受到关注。然而研究结果表明,单独超声波处理对微生物的作用有限,可通过栅栏技术改善这一情况,即联合其他技术手段协同杀菌。杀菌剂应用范围广,兼具价格低廉、易于获得、贮存方便等优势,与超声波联合使用后,既能有效提升杀菌效果,还能减少杀菌剂有害副产物残留、改善杀菌剂渗透性差等问题。本文综述了超声波空化效应导致的超声穿孔、声化学、声致发光效应,重点阐述了超声波联合杀菌剂杀菌的机理和影响因素,以及联用杀菌技术在食品领域的应用,并对未来的研究方向进行了展望,旨在为进一步研究基于超声波与杀菌剂的联用杀菌技术提供参考。 相似文献

High-power ultrasound is a versatile technology which can potentially be used in many food processing applications including food preservation. This is part 2 of a series of review articles dealing with the effectiveness of nonthermal food processing technologies in food preservation focusing on their effect on enzymes. Typically, ultrasound treatment alone does not efficiently cause microbial or enzyme inactivation sufficient for food preservation. However, combined with mild heat with or without elevated pressure (P ≤ 500 kPa), ultrasound can effectively inactivate enzymes and microorganisms. Synergistic effects between ultrasound and mild heat have been reported for the inactivation of both enzymes and microorganisms. The application of ultrasound has been shown to enhance the rate of inactivation of quality degrading enzymes including pectin methylesterase (PME), polygalacturonase (PG), peroxidase (POD), polyphenol oxidase (PPO), and lipoxygenase (LOX) at mild temperature by up to 400 times. Moreover, ultrasound enables the inactivation of relatively heat-resistant enzymes such as tomato PG1 and thermostable orange PME at mild temperature conditions. The extent to which ultrasound enhances the inactivation rate depends on the type of enzyme, the medium in which the enzyme is suspended, and the processing condition including frequency, ultrasonic intensity, temperature, and pressure. The physical and chemical effects of cavitation are considered to be responsible for the ultrasound-induced inactivation of enzymes, although the dominant mechanism depends on the structure of the enzyme. 相似文献

热处理对鲜切果蔬品质影响的研究进展 总被引:1,自引:0,他引:1
鲜切果蔬方便、营养的特性越来越受到加工者和消费者的重视和青睐,然而短暂的货架期已成为限制鲜切果蔬发展的瓶颈难题。为了在保证其食用安全性的前提下,延长鲜切果蔬的货架期,有必要寻找或开发更为环保和安全的鲜切果蔬加工方法,来取代氯水清洗或其他化学试剂在果蔬去皮、切块、清洗等工序中的使用。热处理是一种传统的物理保鲜方法,而将热处理技术应用在鲜切果蔬贮藏保鲜是近年来的研究热点。为此,本文概括了热处理和热处理与其他技术相结合对鲜切果蔬感官品质、营养品质和安全品质的影响,同时归纳了热处理对鲜切果蔬保鲜的机理。以期为热处理应用于鲜切果蔬的贮藏保鲜和提高鲜切果蔬的食用安全提供参考。 相似文献

The food industry faces numerous challenges to assure provision of tasty and convenient food that possesses extended shelf life and shows long-term high-quality preservation. Research and development of antimicrobial materials for food applications have provided active antibacterial packaging technologies that are able to meet these challenges. Furthermore, consumers expect and demand sustainable packaging materials that would reduce environmental problems associated with plastic waste. In this review, we discuss antimicrobial composite materials for active food packaging applications that combine highly efficient antibacterial nanoparticles (i.e., metal, metal oxide, mesoporous silica and graphene-based nanomaterials) with biodegradable and environmentally friendly green polymers (i.e., gelatin, alginate, cellulose, and chitosan) obtained from plants, bacteria, and animals. In addition, innovative syntheses and processing techniques used to obtain active and safe packaging are showcased. Implementation of such green active packaging can significantly reduce the risk of foodborne pathogen outbreaks, improve food safety and quality, and minimize product losses, while reducing waste and maintaining sustainability. 相似文献

Poultry is thriving across the globe. Chicken meat is the most preferred poultry worldwide, and its popularity is increasing. However, poultry also threatens human hygiene, especially as a fomite of infectious diseases caused by the major foodborne pathogens (Campylobacter, Salmonella, and Listeria). Preventing pathogenic bacterial biofilm is crucial in the chicken industry due to increasing food safety hazards caused by recurring contamination and the rapid degradation of meat, as well as the increased resistance of bacteria to cleaning and disinfection procedures commonly used in chicken processing plants. To address this, various innovative and promising strategies to combat bacterial resistance and biofilm are emerging to improve food safety and quality and extend shelf-life. In particular, natural compounds are attractive because of their potential antimicrobial activities. Natural compounds can also boost the immune system and improve poultry health and performance. In addition to phytochemicals, bacteriophages, nanoparticles, coatings, enzymes, and probiotics represent unique and environmentally friendly strategies in the poultry processing industry to prevent foodborne pathogens from reaching the consumer. Lactoferrin, bacteriocin, antimicrobial peptides, cell-free supernatants, and biosurfactants are also of considerable interest for their prospective application as natural antimicrobials for improving the safety of raw poultry meat. This review aims to describe the feasibility of these proposed strategies and provide an overview of recent published evidences to control microorganisms in the poultry industry, considering the human health, food safety, and economic aspects of poultry production. 相似文献
