Abstract

An investigation of various olive oils available in Korea was carried out to assess their quality properties such as color, oxidative stability, fatty acid composition, tocopherol content, sterol content and benzo(a)pyrene content. In color measurement, by using a Lovibond color scale and Hunter color difference meter, both a and b values of extra virgin olive oil were higher than those of pure olive oil by Tintometer (Lovibond PFX995). However, extra virgin olive oil showed higher a value and lower L value than pure olive oil by the Hunter color difference meter. In the rancimat test, the induction period of extra virgin olive oil $(38.03{\sim}8.47hr)$ was longer than that of pure olive oil $(32.40{\sim}9.94hr)$. In fatty acid composition, C18:1 $(72.01{\sim}78.53wt%)$ was present in the greatest amount, with lesser amounts of C18:2 $(4.88{\sim}10.36wt%)$ and C18:3 $(0.56{\sim}1.09wt%)$. The tocopherol content ranged from ${\alpha}-Toc\;4.09{\sim}13.89mg/100g$, ${\beta}-Toc\;0.57{\sim}1.34mg/100g$, and ${\gamma}-Toc$ $3.41{\sim}8.03mg/100g$, and ${\alpha}-tocopherol$ was found to be the main isomer in all oil samples. Therefore, there was little difference in the fatty acid composition and tocopherol content among the different types of olive oils. In sterol content, ${\beta}-sitosterol$ $(124.52{\sim}19.33mg/100g)$ and campesterol $(1.10{\sim}0.62mg/100g)$ of extra virgin olive oil were higher than that of pure olive oil $({\beta}-sitosterol\;92.68{\sim}17.44mg/100g,\;campesterol\;0.59{\sim}0.35mg/100g)$. Benzo(a)pyrene was found in almost all samples, with $0.287{\sim}0.106{\mu}g/kg$ in extra virgin olive oil and $1.204{\sim}2.130{\mu}g/kg$ in pure olive oil.

국내에서 유통 중인 올리브오일 extra virgin 및 pure 등급 13종에 대한 영양성분 및 유해성분 분석을 통해 품질특성을 조사하였다. Tintometer 색도에서는 yellow값, red값 모두 extra virgin 등급이 pure 등급보다 높았으며, Hunter 색도에서는 a값에서만 extra virgin 등급이 높고, L값은 pure 등급이 높아서 extra virgin급이 다소 색이 진한 것으로 나타났다. 산화안정성을 나타내는 Rancimat실험을 한 결과, 유도기간이 extra virgin 등급$(38.03{\sim}8.47hr)$이 pure 등급$(32.40{\sim}9.94hr)$보다 다소 길어서 산화안정성이 비교적 양호한 것으로 나타났다. 영양성분 분석결과에 있어서는 지방산 조성은 $C18:1(72.01{\sim}78.53wt%)$, $C18:2(4.88{\sim}10.36wt%)$, $C18:3(0.56{\sim}1.09wt%)$ 순으로 높았다. Tocopherol 함량은 ${\alpha}$체 $4.09{\sim}13.89mg/100g$, ${\beta}$체 $0.57{\sim}1.34mg/100g$, ${\gamma}$체 $3.41{\sim}8.03mg/100g$ 범위로 ${\alpha}-tocopherol$ 함량이 가장 많았다. 올리브 오일 등급간의 지방산 조성과 tocopherol 함량은 거의 차이가 없었다. Sterol 함량은 extra virgin 등급 올리브오일의 ${\beta-sitosterol}$이 $124.52{\pm}19.33mg/100g$, campesterol이 $1.10{\pm}0.62mg/100g$으로 pure 등급$({\beta}-sitosterol\;92.68{\pm}17.44mg/100g,\;campesterol\;0.59{\pm}0.35mg/100g)$보다 많았다. 유해성분인 benzo(a)pyrene 함량은 extra virgin 등급이 $0.287{\pm}0.106{\mu}g/kg$, pure 등급은 $1.204{\pm}2.130{\mu}g/kg$이었다.
