복분자 부산물(박)을 유용한 천연 색소원으로 활용하기 위하여, 복분자 부산물(박)의 추출조건에 따른 색소 및 폴리페놀의 추출 특성에 대해 조사하였다. 용매 조건별 추출한 색소액의 총 흡광도는 80% 에탄올 용매에서 9.51 unit로 높은 편이었고, 폴리페놀은 에탄올 함량이 40%일 때 최고 수율이었고 에탄올 농도가 높아감에 따라 감소하는 경향이었다. 추출액의 총 흡광도는 용매에 citric acid 및 lactic acid를 첨가하였을 때 높았

With the aim of using Bokbunja byproducts as natural pigments, characteristics of extracts were investigated after application of different extraction conditions. Total optical density (TOD) of pigment extracts was greatest (9.51 units) when 80% (v/v) ethanol was used as solvent. The polyphenol content was greatest when 40% (v/v) ethanol was used and tended to decrease with higher concentrations of ethanol. The TOD values were increased when citric or lactic acid was added to extracting solvents. Polyphenols were effectively extracted by solvent containing ascorbic acid. As the level of byproducts increased with different extraction procedures, TOD and polyphenol content of byproducts tended to decrease. More than 90% of anthocyanin pigments and polyphenols could be obtained using two extractions with 40% (v/v) ethanol.
