Abstract

The elderberry was known to the ancients for its medicinal properties, and in Europe the inner back was formerly administered as a cathartic. The flowers contain a voletile oil, and serve for the distilation of elder-lower water, used in confectionery, perfumes and lotions. The leaves are employed to impart a green colour to fat and oil, and the leaves and bark emit a sickly odour, believed to be repugnant to insect. With its unique flavor and natural food colour, commercial processing companies used the fruit mainly in the making for jam, jelly, pies, juice, and wines. Its vitamin-C content is reported by Andross (1941) as 25-30mg/100g. Harvesting and processing have been mechanized to some extent. However, the cotains with nutritional value has not been reported yet. In the present study the various contains with nutritional value in the fresh elderberry juice is reported by the quantitative analysis. In this study results obtained can be summarized as follows. 1) The fresh elderberry juice contained following mineral elements; calcium 0.012%, magnesium 0.023%, potassium 0.10%, sodium 0.0019%, iron 0.0009%, cobalt 0.0002%, zinc 0.0004%, copper 0.0001%, phosphorus 0.036%, manganese 0.0006%, iodide $1{\mu}g/g$. 2) Five kinds of vitamines were also found ; vitamin-$B_1$ $0.1{\mu}g/g$, vitamin-$B_2$ $0.5{\mu}g/g$, vitamin-C 0.3mg/g, niacin $14{\mu}g/g$, choline chloride 0.3mg/g. 3) Fresh elderberry juice also contains crude protein 1.10%, fat 0.26%, carbohydrate 6.9%, pectin 0.76%, tannin 0.89%, ash 0.80%, water 90.9% and 34.3 cal/100g. 4) The absorption spectrum of the purplishblack color of fresh elderberry juice has a peak between 523-530mm.

Elderberry는 고대인(古代人)에게 약용식물(藥用植物)로 알려졌으며 Europe에서는 옛부터 설사약(지사제(止瀉劑))으로 쓰여 왔다. 꽃은 휘발성 정유(精油)를 함유(含有)하고 있어서 제모(製慕), 향료(香料) 및 로숀 같은 화장품 등에 쓰이는데 주(主)로 꽃을 물로서 증류(蒸溜)해서 사용(使用)하며, 잎은 지방(脂肪)을 green colour로 착색(着色)하는데 사용(使用)되고, 잎과 수피(樹皮)는 곤충(昆虫)이 싫어하는 기피성 물질이 들어 있어서 내충성(耐虫性) 식물(植物)이 된다. 과실(果實)은 향기(香氣)와 천연식용색소(天然食用色素)로서 주요시(主要視)되어 상대적(商業的)으로는 주(主)로 jam, jelly, pies, juice, wine을 만드는데 쓰여진다. 영양가(營養價)는 1941년(年) Andross가 vitamin-c의 함유량(含有量)이 25~30mg/100g 이라고 보고 했으나 그 외(外)의 vitamin이나 각종(各種) mineral 및 영양가(營養價)는 지금까지 보고(報告)된 바 없다. 본(本) 연구(硏究)에서는 각종영양가(各種營養價)와 minerals, vitamins, 그리고 식용천연색소(食用天然色素)의 파장(波長)을 측정(測定)하여 다음과 같은 결과(結果)를 얻었다. 1) 신선(新鮮) Elderberry 과즙(果汁)은 mineral이 11종(種)이 함유(含有)되어 있는 바 Ca : 0.012%, Mg : 0.023%, K : 0.10%, Na : 0.0019%, Fe : 0.0009%, Co : 0.0002%, Zn : 0.0004%, Cu : 0.0001%, P : 0.036%, Mn : 0.0006%, I : $1{\mu}g/g$ 등이 고루 함유(含有)되어 있다. 2) vitamin류(類)는 5종(種)이 함유(含有)되어 있는데, vitamin-$B_1$ : $1{\mu}g/g$, vitamin-$B_2$ : $0.5{\mu}g/g$, vitamin-C : 0.3mg/g, niacin : $14{\mu}g/g$, choline chloride : 0.3 mg/g 으로 되어 있다. 3) 과즙내(果汁內)에는 주요(主要) 영양가(營養價)로서 조단백(粗蛋白) : 1.10%, fat : 026%, carbohydrate : 6.9%, pectin : 0.76%, tannin : 0.89%, ash : 0.80%, water : 90.9% 인데 100g 당 34.3 cal을 보였다. 4) 신선(新鮮)한 과즙(果汁)의 적자색(赤紫色)인 천연색소(天然色素)는 최고파장(最高波長) $523{\sim}530m{\mu}$을 보였다.
