The objective of this study was to investigate the total sugar content of cooked rice (e.g. Bokkeumbap, Deopbap,Bibimbap, Gimbap, Chobap) and side dishes (Jjigae, Kimchi, Jangajji) by using HPLC analysis. Samples were col-lected from six regions in Korea (Seoul, Gyeonggi-do, Chungcheong-do, Gangwon-do, Jeonla-do, Gyeongsangdo).In cooked rice, the total sugar content in Bibimbap (8.537g/100g), Jangeo-deopbap (3.207g/100g), and Saladgim-bap (2.394g/100g) was higher than that of other cooked rice. Also the analysis results showed that the total sugarcontent of cooked rice with spice and sauce added was a little higher than that of other kinds of cooked rice. Fromthe analysis of Jjigae, it was shown that Doenjang-jjigae (1.805g/100g) from the Jeonla-do region had the highesttotal sugar content while there was no difference in total sugar content from the other regions. In case of Kimchi,that from Jeonla-do and Gyeongsang-do was very sweet, salty, and spicy, and the total sugar content was higherthan that from the other regions. The highest total sugar content among the analyzed Kimchi was in Godeulppaegi-kimchi with a value of 8.188g/100g. In addition, the total sugar content in Jangajjie, as a pickle among side dishes,was shown to be higher than that of the other side dishes with the highest range among Jangajjie of 32.865g/100gto 41.846g/100g being found in Maesil-jangajji.
The objective of this study was to investigate the total sugar content in take-out foods by using HPLC analysis.Samples of take-out food were collected from six regions in Korea (Seoul, Gyeonggi-do, Chungcheong-do, Gang-won-do, Jeolla-do, Gyeongsang-do). The samples consisted of 30 main dishes (12 Chinese dishes and 18 flour-baseddishes) and 19 desserts (11 rice cakes and 8 breads). In case of Chinese food, the maximum total sugar content ofTangsuyuk, Ganjajang, Jajangmyeon, and Gun-mandu was 10.346g/100g, 2.409g/100g, 1.589g/100g, and 1.988g/100g respectively. The total sugar content in seasoned Chinese food with sauces was higher than that of the otherChinese food. In case of flour-based food as a main dish, flour-based food seasoned with red pepper paste and manysauces such as Tteokbokki, Naengmyeon, and Guksue had a higher total sugar content than Mandutguk, Tteok-manduguk, and Udong. In particular, Hoe-naengmyeon had the highest total sugar content of 7.194g/100g. Also,desserts (rice cakes and breads), except for Garaetteok, had a high total sugar content with the highest in Glutinousdoughnut and Glutinous rice tteok with red bean paste, which among all the regions analyzed had a maximum totalsugar content of 19.602g/100g from Gyeongsang-do and 30.339g/100g from Seoul respectively.
The aim of this study was to analyze antioxidant activity, total phenolics, and vitamin C content in unripe and ripe jujube cultivar and to investigate correlation between antioxidant and chemical constituents including total phenolics and vitamin C. The antioxidant activity was measured by the DPPH radical scavenging activity, ABTS radical scavenging activity, and reducing power. Although, the weight, diameter and soluble solids of Zyziphus jujuba fruit were increased with the progress of ripening, antioxidant activity and total phenolics were decrease during ripening. The highest free-radical scavenging activity (at 2.5 ㎎/㎖) and reducing power (at 1 ㎎/㎖) in fruit were 81.75% (Bokjo, unripe) and 0.80 (Mudeung, unripe), respectively. The highest total phenolic content in unripe fruit of Mudeung was 62.50 ㎍/g. A linear correlation (r=0.911) was shown between DPPH radical scavenging activity and total phenolic content.
맥문동(麥門冬)의 괴근비대기간중(塊根肥大期間中)의 괴근비대양상(塊根肥大樣相), 수량(收量)및 성분변이(成分變異)를 조사(調査)하기 위하여 맥문동 1호를 공시(供試)하여 '92년 .4월 10일에 30×10cm로 정식(定植)해서 다음해 1월 15일부터 4월 15일까지 15일 간격(間隔)으로 수확하여 수량관련형질(收量關聯形質) 및 성분변이(成分變異)를 조사한 결과를 요약(要約)하면 다음과 같다. 1. 맥문동의 지상부 생육은 월동중(越冬中)에도 계속 증가(增加)하였고 괴근(塊根)의 형성(形成)은 1월 15일 이전에 결정(決定)되는 것으로 판단(判斷)되었다. 2. 괴근의 비대(肥大)는 월동중(越冬中)에 진행(進行)되며 2월 28일 이후에 완료(完了)되는 것으로 나타났다. 그리고 괴근수량은 3월 15일에서 387kg/10a로 최고수량(最高收量)을 보여 수확적기(收穫適期)로 판단(判斷)되었다. 3. 괴근의 전당함량(全糖含量)은 1월 30일에 가장 높았고, 그 이후 점차(漸次) 감소(減少)하여 3월 15일에 가장 낮으며, 전당함량(全糖含量)과 수량(收量)과는 고도(高度)의 부(負)의 유의상관(有意相關)(-0.788**)을 보였다.
