Analysis of Amino Acid and Vitamin in Oak Mushroom (Lentinus edodes Sing)

표고버섯의 아미노산(酸) 및 비타민분석(分析)

Oak mushroom (Lentinus edodes Sing.) has been used as one of vegetable foods for a long time, because it has particular odour, taste and abundant nutritive material. Its cultivation has been done extensively, but its checmical analysis of the components is curiously limited. It is the purpose of this study to analyse its component chemically and to get basic data in terms of nutrition science. The results are summarized as follows: 1. It was analysed that the total number of amino acid is 17 different kinds, mainly glutamic acid. 2. All the essential amino acids which are lecucine, lysine, threonine, tryptophan, valine, phenylalanine, isoleucine, tyrosine, and methionine were found in this chemical analysis. 3. The seven kinds of vitamins are analysed, which are A(${\beta}$-carotene), $B_1$ (thiamin), $B_2$(riboflavin), C(ascorbic acid), E(${\alpha}$-tocopherol), Niacin, choline chloride.

추용(椎茸)버섯의 영양학적(營養學的) 기초자료(基礎資料)의 보강(補强) 및 미분석자료(未分析資料)를 제공(提供)하기 위하여 일반분석(一般分析), amino 산(酸) 분석(分析), vitamin 분석(分析)을 행한 결과(結果)를 요약(要約)하면 다음과 같다. 1) 일반분석(一般分析)은 이미 발표(發表)된 영양분석표(榮養分析表)의 기본(基本) 분석치(分析値)와 유사(類似)하였으며, 2) Amino 산(酸)은 모두 17종 즉, aspartic acid, threonine, serine, glutamic acid, proline, glycine, alanine, valine, methionine, isoleucine, lecucine, tyrosine, phenylalanine, tryptophan, lysine, bistidine, arginine 등이 검색(檢索)되었는데, 가장 많이 함유(含有)된 성분(成分)은 glutamic 산(酸)이었다. 3) 필수(必須) 아미노산 8종(種) 즉, threonine, valine, methionine, isoleucine, lecucine, phenylalanine, tryptophan, lysine 등이 모두 함유(含有)되어 있어서 매우 중요(重要)한 식품(食品)이라는 것을 알수 있었다. 4) Vitamin은 총(總) 7종(種) 즉, A(${\beta}$-carotene), $B_1$ (thiamin), $B_2$(riboflavin), C (ascorbic acid), E (${\alpha}$-tocopherol), Niacin, Cholinechloride이 분석(分析)되었으며 가장 많은 양(量)은 Cholinechloride 이었다.
