Title Of Article :
Identification of spoilage microrganisms in fresh trout fillets coated with silver antimicrobial edible film
Abstract :
In this study fresh trout fillets were coated with colloidal silver antimicrobial edible films and identification of spoilage microorganisms were determined. 0.5 g of colloidal silver was put into 100 ml of edible film coatings. Then this mixture were mixed for 15 min. Fresh trout fillets were dipped into this edible film coating for 1 min for both sides. After 1 minute later trout fillets were put into strafor plates and wrapped with streched film. The microbiological (mesophilic aerobic bacteria count, psychrotrophic bacteria count, Enterobactericeae count, Staphylococcus spp. count, yeast and mould count, lactic acid bacteria count, sensorial (in raw and cooked samples) and pH analyses were done during storage period for groups (control and fresh trout fillets coated with colloidal silver antimicrobial edible film.). According to the results of API test kits; the spoilage microorganisms of trout fillets coated with/without colloidal silver antimicrobial edible film. The identification of dominant bacteria were 99,9 % Pseudomonas fluorescens, 76 % Alcaligenes spp., 76 % Moraxella spp., 99,9 % Lactobacillus salivarius, 99,6 % Lactobacillus brevis and 81,8 % Lactococcus lactis spp.
