4개의 아미노산류(proline 0.29 g, glycine 0.63 g, arginine 0.61 g, methionine 0.02 g)와 과당(fructose 1.07 g)을 홍게 농축자숙액(100 mL, 20oBrix)에 넣고 반응향(reaction flavor)을 유도한 게 향미제 base(CFB)의 휘발성 향기성분을 분석하였다. 총 74종의 휘발성 성분이 검출되었는데, 원료에서는 30개의 화합물이, 대조구에서는 34개, CFB에서는 55종의 화합물이 검출되었으며, 반응향 유도 가열반응에 의해 많은 휘발성 화합물이 생성된 것을 알 수 있었다. 그룹별로 보면 함질소화합물(19종의 pyrazine류, 4종의 pyridine류)이 반응향 유도를 통하여 가장 많이 검출되었고, 대조구에 비해 27배 이상의 함량 증가가 있었다. 함황화합물류(7종)에서는 dimethyl trisulfide 및 dimethyl disulfide 등 2종의 화합물이 전체 함량의 대부분을 차지하였고 반응을 통하여 유의성 있게 증가하였다. 방향족화합물의 종류와 함량은 원료(12종) 및 대조구(3종)에서 반응향 반응을 통하여 CFB(3종)에서는 오히려 감소하였다. Pearson"s 상관분석 결과 tetramethylpyrazine, 2-ethyl-3,5,6-trimethylpyrazine 2,3,5-trimethyl-6-(3-methyl butyl) pyrazine, 2-ethyl-3,5-dimethylpyrazine, 2,5-dimethyl-3-(3-methylbutyl)pyrazine, 2-ethyl-3,6-dimethylpyrazine 및 2-decanone 등 7종의 화합물이 CFB의 관능적향에 영향을 미치는 것으로 나타났다.
Crab-like flavoring base (CFB) was made from a concentrated snow crab cooker effluent (SCCE) containing five food additives (proline, glycine, arginine, methionine, fructose) using reaction flavor technology (RFT). The volatile flavor compounds in CFB were compared between raw (SCCE) and control (without food additives) samples using solid phase microextraction (SPME) and gas chromatography with mass selective detector. A total of 74 compounds were detected in all samples (30 raw samples, 34 control samples, 55 CFB samples). A total of 22 nitrogen-containing compounds, including 19 pyrazines and 3 pyridines, were formed through RFT and increased 27 times compared to the control. Dimethyl trisulfide and dimethyl disulfide were predominant sulfur-containing compounds that increased through RFT, while aromatic compounds decreased through RFT. Seven compounds, tetramethylpyrazine, 2-ethyl-3,5,6-trimethylpyrazine, 2,3,5-trimethyl-6-(3-methylbutyl)pyrazine, 2-ethyl-3,5-dimethylpyrazine, 2,5-dimethyl-3-(3-methylbutyl)pyrazine, 2-ethyl-3,6-dimethylpyrazine, and 2-decanone potentially have a role in CFB odor by Pearson"s correlation analysis.
