헬스케어용 가다랑어(Katsuwonus pelamis) 통조림의 제조 및 특성

초록

This study was conducted to prepare canned skipjack tuna Katsuwonus pelamis in the mixture of isotonic beverage and tomato paste (ST-S) for use as a health food. An analysis of the time-temperature profile and viable cells showed that a reasonable F0 value for ST-S preparation was 4 min. The proximate composition of ST-S was 76.8% moisture, 20.2%crude protein, 0.8% crude lipid, 1.7% ash and 0.5% carbohydrate. The calorie content of ST-S was 94.8 kcal, which is 47.4% lower than that of commercial canned skipjack tuna in oil (ST-O) and 2.2% lower than that of commercial chicken breast in water (CB-B). The total amino acid content of ST-S was 18.54 g/100 g, which is 31.4% lower than that of ST-O and 7.9% lower than that of CB-B. The major amino acids in ST-S were aspartic acid and glutamic acid. An enrichment effect due to such minerals as phosphorus, potassium and iron would be expected on consuming 100 g of ST-S. The major fatty acids in ST-S were 16:0 (27.4%), 18:1n-9 (14.3%) and 22:6n-3 (27.8%), which are different from those in ST-O and CB-B. The major free amino acids in ST-S were glutamic acid (8.1%), histidine (38.6%) and its related dipeptide,such as anserine (15.7%). In an evaluation of taste, flavor and color, ST-S was found to be superior to ST-O and CB-B.
