This study set out to evaluate the microbiological status of rabbit meat and the possibility of using irradiation to control foodborne pathogenic bacteria and extend the refrigerated storage life of meat. Rabbit meat samples were γ irradiated at doses of 0, 1.5 and 3 kGy. The samples were stored at refrigeration temperature, then the effects of irradiation and storage on their microbiological, ...

The natural microflora of cold-smoked fish at the end of shelf-life are lactic acid bacteria (LAB). Some of these display a capacity to inhibit spoilage as well as several strains of pathogenic micro-organisms, e.g. Listeria monocytogenes which is isolated frequently from cold-smoked salmon (CSS). Eight batches of sliced vacuum-packed CSS from Norway, Scotland and Spain were collected at retail...

berangan banana were treated with hot water at 50 ºc for 0 (control), 10, and 20 min and then kept at room temperature (25±2 ºc), 75-80% rh to observe the ripening progress. firmness and activity of cell wall degradation enzymes such as polygalacturonase (pg), pectin methylesterase (pme), and pectate lyase (pl) were determined for treated and untreated banana. the microstructure of banana peel ...

the pomegranate fruits of cvs. malas yazdi and malas ashkezar were immersed in sa (1 and 2 mm from source of acytyl salicylic acid) for five minutes, in ja (0.3 and 0.4 mm from source of n-propyl dihydrojasmonate) for fifteen minutes, in cacl2 (1 and 2%) for five minutes, and in distilled water for five minutes as control. then, the fruits were stored in cold storage at 1.5±0.5ºc and 85±5% rela...

production of part-baked bread is a successful method to postpone bread staling that has been applied widely for production of loaves. in this research, production and some physical characteristics of part-baked flat bread (barbari) including hardness, volume, color, weight loss, and microstructure were studied during the storage of the samples at ambient (25ºc) and freezing (-18ºc) temperature...

Fresh button mushrooms (Agaricus bisporus L.) are sensitive to browning, water loss, and microbial attack. The short shelf-life of mushrooms is an impediment to the distribution and marketing of the fresh product. Essential oils outstand as an alternative to chemical preservatives and their use in foods meets the demands of consumers for natural products. To resolve controlled release of oil an...

The present study was carried out to evaluate the efficiency of gamma radiation (3, 5 and 8 kGy) in combination with low temperature (-20°C) for extending the quality and shelf-life of degutted fresh Chinese pomfret, Pampus chinensis. Quality assessment was studied by monitoring the chemical (TVN, TMA), microbiological (TBC, TMC) and organoleptic changes in irradiated and non-irradiated (contro...

BACKGROUND The product quality of curry is determined by the food animal source, raw materials and the method of processing. Moreover the scientific information on processing and quality of traditional buffalo meat curry from different groups of buffaloes is not available. This study was undertaken to develop processed curry from different buffalo groups and to compare its quality during storag...

Optimal packaging and storage conditions for fresh tilapia fillets were established by evaluating sensory and microbiological changes, as well as monitoring physicochemical properties. Nile tilapia (Oreochromis niloticus) farmed in recirculation aquaculture system was filleted, deskinned, and packaged in air and 50% CO2/50% N2 prior to chilling and superchilling storage at 1°C and -1°C. Sensory...

Cold smoked and gravad fish products can be naturally contaminated with low numbers of Listeria monocytogenes. This could represent a serious hazard for susceptible people. This studied was conducted to determine and quantify the occurrence of this pathogenic bacteria on the Reykjavik retail market, estimate the remaining shelf life using the Pathogen Modelling Program (PMP) and assess the micr...
