본 연구에서는 대왕오징어를 가공식품의 소재로 활용하기 위하여 건조 및 자숙공정을 이용하여 쓴맛 및 신맛을 내는 염화암모늄을 효율적으로 제거하고자 하였으며, 무처리 한 대왕오징어(RGS, Raw giant squid)와 건조과정을 거친 대왕오징어(DGS, Dried giant squid) 및 자숙과정을 거친 대왕오징어(BGS, Boiled giant squid)의 이화학적 성분 비교를 통한 맛성분의 기초자료로 활용하고자 하였다. 각 공정별 오징어의
The chemical components (e.g., proximate composition, nucleotide-related compounds, and amino-acid content) of raw, dried, and boiled giant squids were investigated. The moisture contents of raw, dried, and boiled giant squids were 75.65, 39.75, and 41.12%, respectively. The boiled giant squid had a higher moisture content than the dried giant squid. The crude protein contents of raw, dried, and boiled giant squids were 20.10, 56.25, and 49.58%, respectively, with that of the dried giant squid higher than that of the boiled giant squid. The crude lipid contents of the raw, dried, and boiled giant squids were 0.15, 0.57, and 1.35%, respectively, with the boiled giant squid having the highest crude lipid content. The crude ash content of raw, dried, and boiled giant squids were 1.68, 4.50, and 6.77%, respectively. IMP content was detected in the dried (1.21 mg/100 g) and boiled(0.25 mg/100 g) giant squids. In the sensory scores, the degree of bitterness, acidity, and aftertaste had lower values in the dried and boiled giant squids than in the raw giant squid. A total of 18 amino acids were detected in the samples, and most of the samples had high contents of glutamic acid, aspartic acid, proline, and arginine and low contents of histidine, tyrosine, and methionine. The free-amino-acid content was related to the taste component. The major free amino acid contained by the samples were hydroxyproline, alanine, arginine.
