Tütsülenerek Konservelenen Midye’de (Mytilus galloprovincialis, L.) Mikrobiyal Flora, Su Aktivitesi ve Kimyasal Analizlerin Belirlenmesi
Bu çal›flma, iki farkl› tütsüleme tekni¤i uygulanan ve konservelenen midye’nin su aktivitesi, nem, tuz, pH, asitlik, sirke, toplam bakteri say›s›, koliform, fekal koliform ve Clostridium botulinum düzeyini içermektedir. Bulgulara göre; ortalama su aktivitesi (S2L) 0,971 ± 0,001 ile 0,982 ± 0,001 (TSM) aras›nda de¤iflmektedir. Örneklerin nem içeri¤i; % 69,440 (TSM) ile % 76, 35 (BTS)aras›ndad›r. Gruplar›n baz›lar›nda pH, asitlik, tuz, nem ve sirke aras›ndaki de¤iflim önemlidir (P< 0,05). Likid ve odun duman› ile tütsülenmifl midye, köri sos, domates püreli sos ve ayçiçek ya¤l› sos içerisinde 120 ± 1 ºC ve 5.2 ± 0,1 F0 de¤erinde sterilize edilmifltir. Konserve ürünlerin hiçbirinde 37 ve 55 ºC’deki inkübasyonda bombaj ve C. botulinum’a rastlanmam›flt›r. Konserve öncesi ön ifllem uygulanm›fl midye, toplam bakteri say›s›, fekal koliform, koliform bak›m›ndan herhangi bir risk tafl›mamaktad›r.
The Determination of Microbial Flora, Water Activity and Chemical Analyses in Smoked, Canned Mussels (Mytilus galloprovincialis, L.)
This study reports the water activity, moisture, sodium chloride, pH, acidity, vinegar, total plate count, fecal coliform, coliform and Clostridium botulinum of canned mussels processed by 2 different smoking techniques. The results indicated that the average measured water activity was 0.971 ± 0.001 for liquid smoked canned mussel with curry sauce and 0.982 ± 0.001 for traditional smoked mussel. The moisture of samples varied between 69.440% for traditional smoked mussel and 76.35% for salting before traditional smoking. The moisture, salt, pH, acidity and vinegar were significantly different in some of the groups (P < 0.05). Mussels smoked using liquid and oak wood sawdust, in tomato puree sauce, curry sauce and sunflower oil sauce, were sterilized at 120 ± 1 ºC and 5.2 ± 0.1 F0. In none of the products was swelling or C. botulinum detected at 37 ºC or 55 ºC. Prior to canning, the mussels were investigated for fecal coliform, coliform and total plate count and found to carry no risk in terms of these parameters.
