中文摘要 | 為了解九孔營養價值和衛生品質,乃探討台灣南北部市售和三家養殖場九孔之一般組成分和微生物衛生品質季節變化。得知台灣市售和養殖場九孔其一般組成分平均為水分76.52%,粗蛋白質16.77%,灰分2.23%和脂質0.46%。其中粗脂肪以10月份時較高。微生物衛生品質調查結果發現,北部市售九孔樣品中其總生菌數超過1�e10 CFU╱g者有52.1%,且大腸菌群檢出呈陽性反應者有96.6%,而南部市售九孔樣品中超過1�e10 CFU╱g者有72.9%,大腸菌群檢出呈陽性反應者有93.8%。另外比較台灣三家養殖場九孔之微生物衛生品質,發現內臟中之總生菌數和大腸菌群最確數均較肌肉者為高。而且養殖場九孔之全部檢體中,除2件肌肉檢體外,其總生菌數均超過1�e10 CFU╱g。顯示台灣市售或養殖場之九孔存在有細菌污染的問題。 |
英文摘要 | To establish the untritional value and hygienic quality of the small abalone (Halioties diversicolor), regional and seasonal variations in proximate chemical composition and hygienic microbiological quality in the small abalones collected from markets and aquaculture ponds were studied. It was found that the average value of proximate chemical composition in the small abalones was as follows: moisture 76.12%, protein 16.77%, ash 2.23%, and fat 0.46%. The content of curde fat was higher in October than in other seasons. The ratio of aerobic plate count (APC) over 105 CFU/g in the small abalones collected from northern and southern markets was 52.1% and 72.9%, respectively. The detectable ratio of total coliform (TC) was more than 90% in samples collected from both the north and south of Taiwan. The levels of APC and TC in the small abalones collected from aquaculture ponds were found to be higher in the viscera than in the muscle. Except 2 muscle samples, the value of APC in all samples was higher than 105 CFU/g in both viscera and muscles, showing that the small abalones have been contaminated by microorgainsma. |
