초록

현재 우리나라에서 허용된 식품첨가물인 감초추출물 및 에리스리톨의 경우 천연감미료로서 식품의 제조$\cdot$가공시 다양하게 사용되고 있으나 유통식품 중 식품 중 이들 첨가물의 함유여부 및 함유량을 파악할 수 있는 분석방법이 확립되어 있지 않은 실정이다. 따라서, 본 연구에서는 식품 중 감초추출물 및 에리스리톨의 분석방법을 확립하고, 이를 적용하여 국내유통식품 중 감초추출물 및 에리스리틀의 사용실태를 파악하고자 하였다. 식품 중 감초추출물 및 에리스리톨의 분석방법에 대한 최근 국내의 문헌 및 연구논문 등 기초 자료를 참고로 감초추출물 TLC및 HPLC분석방법과 에리스리톨 HPLC 분석방법을 비교$\cdot$검토하였다. 그 결과 감초추출물은 실리카겔 TLC판을 이용하였으며 TLC 최적용매조건은 부틸알콜 : 4N 암모니아용액 : 에틸알콜 50:20:10)이었다. HPLC 분석은 글리실리진산 (glycyrrhizic acid)을 표준물질로 하여 역상계 컬럼인 Capcell pak $C_{18}$ UG120을 사용하였으며 이동상, UV파장, 컬럼온도는 각각 아세토니트릴 : 물 (38:62), 254 nm 및 $40^{\circ}C$이었다. 에리스리톨의 HPLC 분석은 에리스리톨(meso- erythritol을 표준물질로 하여 역상계 컬럼인 Shodex Asahipak NH2P-50 4E 및 RI 검출기를 사용하였으며 이동상, 컬럼온도는 각각 아세토니트릴 : 물 (75:25), $30^{\circ}C$이었다. 글리실리진산은 서울,부산 등 11개 도시에서 구매한 국내 유통 가공식품 중 장류 18품목, 소스류 12품목, 건강기능식품류 15품목, 음료류 26품목, 주류 8품목, 과자류 23품목, 절임류 3품목 등 총 7종 105품목을 대상품목으로 하였으며 이 중 장류, 소스류, 건강기능식품, 음료류, 주류에서 각각 ND$\∼$48.7 ppm, ND$\∼$5.3 ppm, ND$\∼$988.9 ppm, ND$\∼$180.7 ppm, ND$\∼$2.6 ppm의 글리실리진산이 검출되었고, 나머지 품목은 모두 불검출이었다. 에리스리틀의 경우 껌류 13품목, 캔디류 15품목, 음료류 12품목, 건강기능식품류 12품목등 총 4종 52품목을 대상품목으로 하었으며, 껌류 및 건강기능식품에서 각각 ND$\∼$155.62 ppm, ND$\∼$398.14 ppm의 에리스리톨이 검출되었으며, 나머지 품목은 모두 불검출이었다. 본 연구결과는 식품 중 천연감미료인 감초추출물 및 에리스리톨의 분석방법 확립함으로써 국내유통식품의 감초추출물 및 에리스리톨 사용실태파악 및 사후 식품의 품질관리에 기여할 수 있을 것으로 사료된다.

Licorice Extract and Erythritol, food additives used in korea, are widely used in foods as sweetener. Its application for use in food is regulated by the standard and specification for food additives but official analytical method far determination of these sweetener in food has not been established. Accordingly, we has been carried out to set up analytical method of the glycyrrhizic acid in several foods by the way of thin layer chromatography and high performance liquid chromatography glycyrrhizic acid is qualitative anaylsis technique consists of clean-up with a sep-pak $C_{18}$ cartridge, separation of the sweeteners by Silica gel 60 F254 TLC plate using 1-butanol:4Nammonia solution:ethanol (50:20:10) as mobile solvent. Also, the quantitative analysis for glycyrrhizic acid, was performed using Capcell prk $C_{18}$ column at wavelength 254nm and DW:Acetonitrile (62:38 (pH2.5)) as mobile phase. and we has been carried out to set up analytical method of the erythritol in several foods by the way of high performance liquid chromatography. erythritol is qualitative anaylsis technique consists of clean-up with a DW and hexane. The quantitative analysis for erythritol, was performed using Asahipak NH2P-50 column, Rl and DW:Acetonitrile (25:75) as mobile phase. The glycyrrhizic acid results determined as glycyrrhizic acid in 105 items were as follows; N.D$\∼$48.7ppm for 18 items in soy sauce, N.D$\∼$5.3ppm for 12 items in sauce, N.D$\∼$988.93ppm for 15 items in health food, N.D$\∼$180.7ppm for 26 items in beverages, N.D$\∼$2.6ppm for 8 items in alcoholic beverages repectively and ND for 63 items in the ethers. The erythritol results determined as erythritol in 52 items were as follows; N.D$\∼$155.6ppm for 13 items in gm, N.D$\∼$398.1ppm for 12 items in health foods repectively and ND for 45 items in the others.
