Abstract

In this study, we evaluated black pepper seed and white pepper seed for the following compounds: piperine content was determined by HPLC, and volatile oil content was determined via the Soxhlet method in before/after heat-treated samples, and total volatile material contents were determined via the SDE(Linkens-Nikens type simultaneous steam distillation and extraction apparatus) method. As a result, differences were noted in the black and white pepper seeds according to the constituent components, growing district, and whether the species was indigenous to Indonesia or India. We concluded that the differences in taste were attributable to the differences in the volatile material contents in black and white peppers. We also assessed these three determination results, and found that they were directly correlated. The volatile oil contents were determined by the Soxhlet method, which was a rapid, simple, and accurate method. We concluded that this method should prove to be an effective determination method in the quality control of black and white peppers.

흑후추와 백후추 원두에서 HPLC에 의한 piperine 함량, 가열처리 전후의 시료에 대한 Soxhlet법을 이용한 휘발성 기름성분 함량, SDE(Linkens-Nikens type simultaneous steam distillation and extraction apparatus)법을 이용한 총 휘발성 물질 함량 등을 측정하였다. 그 결과, 흑후추와 백후추의 구성성분차이, 인도네시아와 인도의 산지 기후조건 및 품종 차이 등에 따른 편차는 인정되었으나 전체적으로 일정한 범위 내에서 차이를 나타내었다. 후추에서 맛의 차이는 맛 성분의 차이보다는 휘발성 물질의 함량 차이가 큰 영향을 미쳐 냄새를 일반적으로 맛으로 착각하는 경향이 있는 것으로 판단된다. 이로부터 상호간의 측정결과를 비교평가해 본 결과 일정 수준의 비례적 관계를 갖는 것으로 나타나 현장의 품질관리 등에서 간편하고 신속하게 결과를 측정할 수 있는 Soxhlet법에 의한 휘발성 기름 성분 함량 측정법을 후추의 중요한 품질평가 방법의 하나로 활용할 수 있을 것으로 기대되는 결과를 얻었다.
