Preparation of Functional Healthy Drinks by Ethanol Extracts from Defatted Safflower Seed Cake

탈지 홍화씨박 에탄올추출물 함유 기능성 건강음료의 제조

Functional healthy drinks were processed with freeze dried powders of ethanol extract from of defatted safflower (Carthamus tinctorious L.) seed cake and some useful components of the drinks were investigated. Yield of freeze dried powder was the highest as 8.42% when it extracted with 60% ethanol (60% EFDP). Each drink contained 0.02% of freeze dried powder and ranged 10.6∼13.8% of soluble solid, 2.90∼3.68 of pH, 0.10∼0.83% of titratable acidity. ‘L’ value of drink-I (DSD-I) was the highest as 94.82$\pm$2.45, ‘b’ and ‘a’ value of drink-V (DSD-V) was highest as 27.15-2.65 and 28.67$\pm$2.69, respectively. Major free sugars of drink were 6015.3∼7918.2 mg% of glucose and 1511.4∼2091.0 mg% of sucrose. The content of citric acid was the highest as 179.2∼981.3 mg%. The content of total phenol in 60% EFDP was 99.17 mg% and that of drink-II(DSD-II) and DSD-V was 307.84 mg% and 224.06 mg%, respectively. Total flavonoid was contained as 50.29 mg% in 80% ethanol extract (80% EFDP) and 125.20 mg% in DSD-V. N-[2-(5-hydroxy-1H-indol-3-yl) ethyl] ferulamide (serotonin-I) was determined as high as 18.81 ppm in 80% EFDP and ranged 2.42∼2.89 ppm in drinks. N-[2-(5-hydroxy-lH-indol-3yl)ethyl]-p-coumaramide (serotonin-II) was determined as 30.17 ppm in 80% EFDP and ranged 3.79∼4.59 ppm in drinks. Acacetin, flavonoid compound were 9.83 ppm in amyloglucosidase hydrosis + 60% ethanol extract (A + 60% EFDP) and ranged 0.98∼1.26 ppm in drinks. Electron donating ability (EDA, %) was measured and compared with 100 ppm BHA as chemical antioxidant. EDA was 93.97$\pm$2.21% in A+60% EFDP, 94.79$\pm$2.26% in DSD-I, 94.69$\pm$1.37% in DSD-II, and 93.83$\pm$1.49% in BHA. DSD-II added with hot water extract solution from Korean ginseng and safflower yellow pigment recorded the highest sensory score.

탈지 홍화씨박 에탄올추출 동결건조분말을 첨가한 기능성 건강음료의 제조와 유용성분을 조사하였다. 수율은 60% 에탄올추출 동결건조분말이 8.42%로 가장 높았고, 당도는 10.6∼ 13.8%, pH는 2.90∼3.68, 적정산도 0.10∼0.83 수준이었다. L값은 DSD-I가 94.82$\pm$2.45, a값과 b값을 DSD-V가 27.15$\pm$2.65와 28.67$\pm$2.69로 높은 값을 보였다. Glucose는 6015.3∼7918.2mg%, sucrose는 1511.4∼2091.0mg% 수준으로 음료의 주된 당으로 확인되었고, 유기산으로는 citric acid가 179.2∼981.3mg% 수준이었다. 총페놀 함량은 60% 에탄올추출 동결건조분말이 99.17mg%와 DSD-II 307.84mg%와 DSD-V에 224.06mg%로 많은 양을 함유하고 있었다. 총플라보노이드 함량은 80% 에탄올추출 동결건조분말에 50.29mg%와 DSD-V에 125.20mg%로 다소 많은 양을 함유하고 있었다. Serotonin-I 함량은 80% 에탄올추출 동결건조 분말에 18.81 ppm과 음료는 2.42∼2.89 ppm 수준으로 함유하고 있었다. Serotonin-II함량 역시 80% 에탄올추출 동결건조분말에 30.17 ppm과 음료는 3.79∼4.59 ppm 수준으로 함유하고 있었다. Acacetin 함량은 amyloglucosidase 가수분해 후 60% 에탄올추출 동결건조분말에 9.83 ppm과 음료는 0.98∼1.26ppm 수준으로 함유하고 있었다. EDA(%)는 amyloglucosidase 가수분해 후 60% 에탄올추출 동결건조분말이 93.97$\pm$2.21%와 음료는 DSD-I이 94.79$\pm$2.26%와 DSD-II가 94.69$\pm$1.37%로 BHA 100 ppm 농도 93.83$\pm$1.49%보다 높은 항산화 활성을 보였다. 음료의 관능평가에서는 1% 인삼추출액과 홍화 황색색소를 첨가하여 제조한 DSD-II가 전반적으로 높은 관능 점수를 얻었다.
