도토리 화분(꽃가루)의 물리적 처리에 의한 성분 변화

This study was conducted to establish the optimized protocol for cytoplasm isolation of bee pollen. Data of biochemical parameters and amino acid profiles were obtained from acorn pollen grains treated with pulverization or lyophilization. Contents of moisture, ash, crude protein and crude fat of acorn pollen were 11.7%, 2.6%, 24.1% and 11.8%, respectively. After pulverizing, content of crude protein was decreased to 23.8% while crude fat was 22.5% which means 90% increase. Also content of crude protein was increased to 26.5% in case of the lyophilized pollen. Amino acids such as aspartic acid, glutamic acid, leucine and arginine were extensively found in acorn pollen while histidine, methionine and cystine were infrequent. The pulverized pollen was increased by 2.6% in the total amino acid percentage while the lyophilized pollen increased by 11.8% compared to the untreated pollen.
