2012년 2월부터 11월까지 인천 지역에서 유통된 건고추 및 고춧가루 193건을 대상으로 아플라톡신 $B_1$과 오크라톡신 A의 오염도를 조사하였다. Immunoaffinity column 및 HPLC를 이용한 시험법은 모두 80% 이상의 회수율을 보였고, 아플라톡신 $B_1$ 및 오크라톡신 A의 검출한계는 각각 0.13 ${\mu}g/kg$, $0.30{\mu}g/kg$였다. 오염도 조사를 한 결과 아플라톡신 $B_1$은 17.1%의 검출율을 보였고 오크라톡신 A는 20.7%의 검출율을 보였으며, 아플라톡신 $B_1$의 검출농도는 0.14~9.67 ${\mu}g/kg$였고, 오크라톡신 A의 검출 농도는 0.31~3.31 ${\mu}g/kg$였다. 이는 우리나라 식품공전 상의 기준인 10 ${\mu}g/kg$(아플라톡신 $B_1$), 7 ${\mu}g/kg$(오크라톡신 A)보다는 낮은 수치로 비교적 안전한 수준이었다. A survey of aflatoxin $B_1$ and ochratoxin A was conducted on dried red pepper and red pepper powder. Total number of 193 samples were collected from local markets in Incheon. The presence of aflatoxin $B_1$ and ochratoxin A was determined by high performance liquid chromatography (HPLC) with fluorescence detector using immunoaffinity column clean-up. The recovery rate of aflatoxin $B_1$ and ochratoxin A were more than 80% and the limits of quantification were 0.13 ${\mu}g/kg$ for aflatoxin $B_1$ and 0.30 ${\mu}g/kg$ for ochratoxin A. Aflatoxin $B_1$ was detected in 33 samples (17.1%) with a range of 0.14~9.67 ${\mu}g/kg$ and ochratoxin A was detected in 40 samples (20.7%) with a range of 0.31~3.31 ${\mu}g/kg$. These results show that the occurrence of aflatoxin $B_1$ and ochratoxin A in dried red pepper and red pepper powder tested in this study is low compared with the standard in Korea Food Code (10 ${\mu}g/kg$ as aflatoxin $B_1$ and 7 ${\mu}g/kg$ as ochratoxin A).

Purpose: This study examined the effects of aronia, beet and prickly pear powder on the properties of mul-kimchi made of turnip. Methods: Each turnip mul-kimchi was made by adding 0.2% aronia, beet or prickly pear powder. After a 24 hour fermentation process at $25^{\circ}C$, it was stored at $4^{\circ}C$. The antioxidant activities and quality characteristics of turnip mul-kimchi during 34 days of storage at $4^{\circ}C$ were compared. The antioxidant activities were evaluated using DPPH (2,2-diphenyl-1-picryl-hydrazyl-hydrate) and ABTS (2,2'-azinobis-3-ethylbenzothiazoline-6-sulphonic acid) radical scavenging methods, as well as FRAP (ferric reducing antioxidant power) assays and the total polyphenol content. Results: The antioxidant activity of aronia-added turnip mul-kimchi was higher than that of the control and others. The vitamin C content was the highest on day 6, with the following levels: aronia-added turnip mul-kimchi (182.36 mg/kg), beet-added turnip mul-kimchi (171.80 mg/kg), prickly pear-added turnip mul-kimchi (163.80 mg/kg) and control group (158.85 mg/kg). Conclusion: The addition of aronia powder can improve the quality characteristics and antioxidant activities of turnip mul-kimchi.

국내 유통 알부틴 함유 미백 기능성화장품 중 히드로퀴논 및 살균보존제 안전성 조사

조중희 ( Joong Hee Cho ),김지형 ( Ji Hyeung Kim ),엄선아 ( Sun Ah Eom ),강민정 ( Min Jeong Kang ),한영선 ( Young Sun Han ),허명제 ( Myong Je Hur ) 대한화장품학회 2019 대한화장품학회지 Vol.45 No.4

미백 성분으로 사용되는 알부틴은 피부질환 및 발암물질로 알려진 히드로퀴논을 생성할 수 있으며, 살균보존제는 화장품을 장기간 보관 및 사용 중 미생물의 오염을 방지하기 위해 필수적이기는 하지만 독성 및 피부 자극 등 안전성의 문제가 제기되고 있다. 이번 연구에서는 온·오프라인으로 판매되는 알부틴 함유 미백 기능성화장품 40건을 대상으로 히드로퀴논과 살균보존제 21종에 대하여 함량 및 사용실태를 조사하였다. 그 결과, 히드로퀴논은 9건이 검출 되었으며, 이 중 7건에서 0.3 ∼ 0.9 ppm으로 식품의약품안전처에서 설정한 기준에 적합하였으나, 2건에서는 8.4 ppm, 50.5 ppm으로 검출이 되어 기준을 초과하였다. 살균보존제는 40건 중 20건에서 검출되었으며, 검출 항목 및 범위는 페녹시에탄올 0.1 ∼ 0.7% (15건), 메틸파라벤 0.19 ∼ 0.21% (2건), 클로르페네신 0.13% (1건), 클로르헥시딘 0.006%(1건), 프로필파라벤 0.06% (1건) 로 모두 기준 이내로 검출되었다. 또한 화장품 중 기능성 화장품의 경우 화장품법에 의하여 1차 또는 2차 포장에 기능성 화장품이라는 단어를 표기해야 하지만 40건 중 1건에서 표기가 되어 있지 않았다. 실험 결과 살균보존제는 안전하게 관리 되는 것으로 판단되지만, 히드로퀴논이 검출된 제품은 알부틴이 분해되어 생성되었다고 사료 되어 알부틴의 분해에 대한 추가적 연구 및 품질관리의 개선이 요구된다. Arbutin, which is used as a whitening ingredient, can produce hydroquinone, known as causing skin disease and carcinogen. Preservatives are essential to prevent microbial contamination during long-term storage and use of cosmetics, but safety issues such as toxicity and skin irritation are being raised. This study was conducted to determine hydroquinone and 21 preservatives levels in 40 arbutin-containing whitening functional cosmetics sold on-line and off-line. Result showed that 9 products contained hydroquinone. The concentrations in 7 products were ranged from 0.3 to 0.9 ppm, which were within the maximum allowed amount established by the Ministry of Food and Drug Safety. However, 2 products were 8.4 and 50.5 ppm and exceeded the allowed amount. Preservatives were detected 20 products. Detected items and ranges were phenoxy ethanol 0.1 ∼ 0.7% (N = 15), Methyl paraben 0.19 ∼ 0.21% (N = 2), Chlorphenesin 0.13% (N = 1), chlorhexidine 0.006% (N = 1), Propyl paraben 0.06% (N = 1), which were within maximum allowed amount established by the Ministry of Food and Drug Safety. Also, in cases of functional cosmetics the phrase "functional cosmetics" should be expressed on the primary or secondary package of cosmetics by cosmetics act. However, 1 product did not state the phrase as functional cosmetics. This study suggest that preservatives were safely managed. However, hydroquinone in hydroquinone-detected products could be produced by the decomposition of arbutin. Thus, further studies on the decomposition of arbutin are required to improve the quality control of the cosmetics.

BACKGROUND: This study was conducted to investigate the levels of pesticide residues in fruits and to assess their METHODS AND RESULTS: Monitoring of 215 samples of fruits collected from local markets in incheon during 2013 was performed. 259 pesticides were analyzed by multi-residue method and Quick, Easy, Cheap, Effective, Rugged, and safe/Mass/Mass(QuEChERS/MS/MS) method using Gas Chromatography-Electron Capture Detector/Nitrogen Phosphorus Detector(GC-ECD/NPD), GC-MS, LC(Liquid Chromatography-Mass/Mass(LC-MS/MS) and High Performance Liquid Chromatography-Photodiode Array/ Fluorescence Detector(HPLC-PDA/FLD). In 56.3% of the samples detected pesticide residues and were not found to exceed Maximum Residue Limits(MRL). The highest detected samples were found in citrus fruits(83.9%). Among the detected compounds, carbendazim(13.1%), imazalil (11.7%), thiabendazole(10.7%) and fludioxonil(9.8%) were frequently found in fruits. A risk assessment of pesticide residues in fruits was performed by calculating Estimated Daily Intake(EDI) and Acceptable Daily Intake(ADI). Also, we were evaluated removal efficiency of pesticide residues by washing and peeling. The removal efficiency of pesticide residues in citrus and tropical fruits by peeling processes were 91.6%. After the washing process, the removal rates were 43.1%(Cherry, Grape, Blueberry). CONCLUSION: The level of pesticide residues in fruits was within the MRL. The range of %ADI values was from 0.00011 to 0.98795%. The process of washing or peeling reduces the level of pesticide residues. The results of this research concluded that the detected pesticides are not harmful to human being.

Purpose: To present our treatment protocol and surgical outcome for patients with congenital brachymetatarsia in which treatment was decided according to the number of affected rays. Materials and Methods: Sixty-nine metatarsals in 44 patients with single or multiple congenital brachymetatarsia were included in the study. When a single ray was affected in a foot, we performed a one-stage lengthening using an intercalary autogenous iliac bone graft. We overcame excessively short rays by the double level lengthening at the metatarsal and proximal phalanx as one stage. When multiple rays were affected in one foot, we performed a one-stage combined shortening and lengthening procedure without an iliac bone graft. Results: All patients were satisfied with the cosmetic and functional results. The average length gain by one-stage lengthening in 56 metatarsals of 38 patients was 14 (6-21) mm. Six patients with a combined shortening and lengthening procedure regained a nearly normal parabola of the involved foot. Neurovascular complication was not identified. Conclusion: Satisfactory results were achieved for the treatment of patients with congenital brachymetatarsia, by individualizing the surgical options according to the number of affected rays and general foot appearance.
