as special spoilage organisms of tilapia stored at 0-15℃. At the end of shelf life, the average number of Pseudomonas spp. was 7.70±0.11 log 10cfu·g~ -1 at temperatures 0,5,10 and 15 ℃.
The result showed that carboxymethyl-chitosan had stronger bacteriostasis against above-mentioned common bacteria in polluted food. The minimum inhibition concentration(Mic) is 0.1% for staphylococcusaureus, 0.2% for escherichiacoli and bacillussubtilis.
Fish evaluations for 12 days of storage in ice included sensory (EU and the QIM scheme), physical (Torrymeter and Freshmeter) and microbiological changes [counts of total bacterial numbers, specific spoilage organisms (SSO) and Pseudomonas].
It is bacteriostatic or bactericidal to gram-positive bacteria based on its activity as a proton-ionophore, and a broad range of food-related spoilage organisms and pathogens is inhibited by reutericyclin.
Seeds and cereal grains can be treated with low energy (>amp;lt;300?keV) or high energy (1-10?MeV) electrons for decontamination of phytopathogenic and spoilage organisms.
Antimicrobial activity of carboxymethyl-chitosan were studied by using escherichiacoli, staphylo- coccusaureus and bacillussubtilis as experimental bacteria. The result showed that carboxymethyl-chitosan had stronger bacteriostasis against above-mentioned common bacteria in polluted food. The minimum inhibition concentration(Mic) is 0.1% for staphylococcusaureus, 0.2% for escherichiacoli and bacillussubtilis. The experimental results showed that 0.5% carboxymethyl-chitosan solvent can extend the storage lif...
The microbiological quality change characteristic, high quality life and shelf life of tilapia stored aerobically at 0, 5, 10 and 15℃ were studied in order to investigate its chilled chain distribution feasibility. At the same time, the correlation between the numbers of Pseudomonas spp (special spoilage organisms of cultured freshwater fish stored aerobically at 0~15℃), the total aerobic counts, VBN, and sensory freshness were also discussed in this paper. The results showed that tilapia is a species of fr...
A series of experiments had been carried out to develop and validate the growth kinetics model of specific spoilage organisms for predicting the microbial quality and remaining shelf life of cultured tilapia stored aerobically in cold temperature. The results from microbiological behaviors analysis, organoleptical quality and TVBN evaluation identified Pseudomonas spp. as special spoilage organisms of tilapia stored at 0-15℃. At the end of shelf life, the average number of Pseudomonas spp. was 7.70±0.11 log...
