담양군 죽순으로 제조한 죽순식초와 시판 과실식초의 이화학적 특성인 산도, 무기질, 아미노산, 플라보놀을 비교 분석하고 SBSE-GC/MS방법을 사용하여 향기성분을 분석하였다. 죽순식초의 산도는 4.49%로 제일 낮았으며 무기질 중 Na의 경우 8.36 mg/100 g으로 다른 과실식초에 비해 그 함량이 낮았다. 아미노산은 다른 시판 식초에 비해 tyrosine과 lysine의 함량이 높았으며 flavonol aglycone 중 quercetin이 3.29 mg/L 들어있었다. SBSE방법으로 향기성분을 분석한 결과 aldehyde류의 함량이 시판식초에 비해 높았으며 특이적으로 수면 유도물질로 알려진 oleamide가 처음으로 검출되었다.
We assessed the quality of a bamboo shoot vinegar produced in Damyang-gun in terms of parameters that included acidity, mineral contents, amino acids, and flavonol aglycones. The flavor compounds of the bamboo shoot vinegar were also analyzed using the stir bar sorptive extraction (SBSE) method. The acidity of the bamboo shoot vinegar was 4.49%, which was the lowest value among the commercial vinegars studied. The bamboo shoot vinegar had a lower concentration of Na (8.36 mg/100 g) than the other commercial vinegars. There was a relatively large amount of tyrosine and lysine in the bamboo shoot vinegar. The concentration of quercetin, a flavonol aglycone, was 3.29 mg/100 g. The results of the flavor analysis showed that hexanal, 2-furancarboxaldehyde, and benzaldehyde were high in the bamboo shoot vinegar. Oleamide, a compound that is known to induce sleep, was first found in bamboo shoot vinegar using the SBSE method.
