ABSTRACT

Snail (Archachatina Marginata) meats were processed into 3 different forms. Such that Ti was boiled and served as control. While T2 was boiled and fried. And 13 was boiled, coated with batter, dusted with breading and then fried. A comparative study of shelf life of these samples was conducted within 36 storage days. From tables I, ii, iv microbiological quality of Ti, 12; and 13 were determined for the 36 days of storage. Such that microbiological quality of Ti, 12, andT3 under freezing temperature storage was guaranteed after 36 days of storage. Like wise samples (stored under refrigeration, while samples stored under room temperature were not microbiologically guaranteed after 36 days of storage. However the most common microbial growth irrespective of storage temperature was mould (penicillium, Botrytis, and fusarium). Though mould growth cannot be said to be spoilage, rather suggests poor packaging and storage condition. Especially when they are not up to the stage where toxins are produced. In order words the presence of mould suggests poor packaging .However mold growth was a bit higher when compared to those of Ti, arid 12.This is because of the precence of baPer and breading.. In all a <100 foot cell aggregate per gram of staphylococcus spp. Was deducted after the analysis.Batter and breading coating was found to have cryoprotectant effect ,thus protected the staphylococcus spp from the full elimination effect of freezing and refrigeration temperature.
