Background and purpose: Today, the use of natural preservatives in increasing meat products shelf life has gained much attention. In this study, we aimed at evaluating the effects of eucalyptus and cuminum essential oils on microbial quality of Oncorhynchus mykiss. Materials and methods: In an experimental study the eucalyptus and cuminum essential oils were prepared and their antibacterial ...
The effects of ultraviolet (UV) radiation were investigated with regards to the microbial growth inhibitory effect on the shelf life of Korean native cattle (Hanwoo) beef prior to refrigerated storage. The Hanwoo samples were exposed to UV radiation (4.5 mW/cm(2)) for 0, 5, 10, 15, and 20 min. The UV-irradiated beef that was exposed for 20 min showed significantly reduced mesophilic and psychro...
The effect of vacuum packing on the shelf-life of sausages produced from Capoeta umbla were investigated during storage periods. For this purpose, microbial, chemical and sensory changes were analyzed throughout the storage time. The microbial flora of the sausages comprised mainly mesophilic bacteria, psychrotrophic bacteria, lactic acid bacteria, yeast and molds. Escherichia coli, Staphylcocc...

Extended shelf-life (ESL) or ultra-pasteurized milk is produced by thermal processing using conditions between those used for traditional high-temperature, short-time (HTST) pasteurization and those used for ultra-high-temperature (UHT) sterilization. It should have a refrigerated shelf-life of more than 30 days. To achieve this, the thermal processing has to be quite intense. The challenge is ...
Amylase is one of the most widely used enzymes in the industry. Cold environments are the most ubiquitous environments in the world that have been occupied by cold tolerant microorganisms. The enzymes of these microorganisms have a wide range of applications in various areas of biotechnology. The aim of this study was to isolate cold-active amylase producing bacteria. A total of 64 cold-toleran...
