Abstract
An attempt was made to investigate the chemical compositions of green pumpkin, edible flesh and seed of ripened pumpkin (Cucurbita moschata Duch.). The proximate compositions were moisture 9.34%, 11.98%, protein 12.70%, 13.38%, lipid 11.31%, 0.85%, carbohydrate 64.32%, 62.18%, fiber 6.31%, 4.54% and ash 6.05%, 7.76% in green and ripened pumpkin, respectively. The compositions of free sugar were glucose, fructose, sucrose, lactose and maltose in green and ripened pumpkin, respectively. During flesh growth, glucose, maltose and lactose was increased but sucrose and fructose was decreased in pumpkin. Pattern of 15 amino acid compositions in green and ripened pumpkin was shown to be of similarity. Major amino acids were glutamic acid, aspartic acid and alanine in green pumpkin and edible flesh of ripened pumpkin. And major amino acid in seed of ripened pumpkin were glutamic acid, arginine, aspartic acid and leucine. The predominant fatty acids were palmitic acid, linolenic acid, linoleic acid and oleic acid in green and ripened pumpkin, respectively. And those in seed of ripened pumpkin were linoleic acid, palmitic acid and oleic acid. The richest mineral contained in the green and ripened pumpkin was shown to be K and followed by Ca, Mg, Na and Fe in order.
미숙호박과 완숙호박의 일반성분, 유리당, 아미노산, 지방산, 무기성분 조성등의 화학성분을 비교 조사한 결과, 호박은 성숙함에 따라서 성분이 변화하는 경향을 보였다. 미숙호박 및 완숙호박의 과육중에는 당질
