不同类型发酵香肠产品特性及其栅栏效应的比较研究 总被引:3,自引:1,他引:3
可将发酵香肠大致分为干香肠、半干香肠和非干燥发酵肠三种类型。干香肠的防腐保质栅栏主要建立于aw值(降低水分活度值)之上,半干香肠也是以aw值为主,同时pH(发酵酸化)和c.f.(优势菌群)起到重要辅助作用。对于非干燥发酵肠,pH值作为主要栅栏因子与aw、c.f.等互作效应决定产品的质量特性。根据产品特性分析,对开发适宜我国消费习惯的发酵香肠产品提出了建议。 相似文献

香豉兔肉防腐保质栅栏因子的调控研究 总被引:4,自引:0,他引:4
在新型兔肉干制品开发中,对决定产品感官和可贮性的主要特性指标进行了研究。结果表明,添加2.0%食盐,3.0%白糖,70℃烘烤干燥2h,使肉料至含水量30.5%,将产品理化值确定于aw0.86,pH5.9,NaCl3.9%,糖4.5%时产品风味最佳,而以aw0.86作为保证产品可贮性和质量特性的主要栅栏因子,在通过高温杀菌设置的F因子(110℃,10min)与aw互作效应,可使产品在尽可能保持特有风味的同时,感官质量和货架寿命优于传统肉干。 相似文献

BackgroundIn recent years, there has been growing consumer demand for the minimally processed and chemical additives free Ready-To-Eat (RTE) healthier meat products. On the other hand processed and RTE meat products have been notified as the primary cause for food borne outbreaks in different countries that commonly associated with emerging pathogens such as Salmonella, Listeria monocytogenes and Escherichia coli species.Scope and approachHigh pressure processing (HPP) has been renewed as a best non-thermal intervention for extending the shelf-life and safety of RTE meat products without altering the sensory and nutritional properties. Meat products are complex medium with different physical and chemical compositions that influence the lethality of the microorganisms during HPP. Using high pressure levels (above 600 MPa) for complete sterility of meat products may not be economically feasible more over it may negatively affect the product quality characteristics. The present review aimed to explore the recent research investigations addressed the multi hurdle approaches to increase the effectiveness of HPP at lower processing levels in order to reduce the processing costs and to improve the safety and quality of processed meat products.Key findings and conclusionsThe combination of natural antimicrobials (plant bioactive compounds and bacteriocins) and antioxidants (plant phenolic compounds) as additional hurdles through different mechanisms (active and intelligent packaging) during HPP can definitely be an effective and innovative intervention in ensuring the complete safety of processed meat products. Moreover, the development of low salt meat products with optimum quality attributes can be highly possible through HPP technology. 相似文献

Modern‐day processing of meat products involves a series of complex procedures designed to ensure the quality and safety of the meat for consumers. As the size of abattoirs increases, the logistical problems associated with large‐capacity animal processing can affect the sanitation of the facility and the meat products, potentially increasing transmission of infectious diseases. Additionally, spoilage of food from improper processing and storage increases the global economic and ecological burden of meat production. Advances in biomedical and materials science have allowed for the development of innovative new antibacterial technologies that have broad applications in the medical industry. Additionally, new approaches in tissue engineering and nondestructive cooling of biological specimens could significantly improve organ transplantation and tissue grafting. These same strategies may be even more effective in the preservation and protection of meat as animal carcasses are easier to manipulate and do not have the same stringent requirements of care as living patients. This review presents potential applications of emerging biomedical technologies in the food industry to improve meat safety and quality. Future research directions investigating these new technologies and their usefulness in the meat processing chain along with regulatory, logistical, and consumer perception issues will also be discussed. 相似文献

so as to implement some innovations in food industry associated with processing, preservation, and storage of the products
based on the food safety issues. Attention is focused on the engineering aspects of the immobilized cell techniques with emphasis
on the mass-balance-based mathematical modeling of the system. Some aspects of models for safety, quality, and competitiveness
of the food processing sector are also presented. Ultimately, development of products with novel properties within the alcoholic
beverages, meat processing/preservation, manufacture of cheese and bread, sweeteners and pigments, as well as nutraceuticals
is also addressed. 相似文献
