Abstract
This study was carried out to analyze useful component in freeze-dried persimmon flower powder made from six cultivais. The cultivais were Dogunjosang, Kojongsi, Kabjubaeknok, Chalang, Weolhasi and SangjuDungsi. Powder of persimmon flower was prepared by milling after freeze drying at $-70^{\circ}C$. Crude lipid was the highest in Dogunjosang (57.26%). Major free sugars of the persimmon flowers were fructose ($95{\sim}310mg%$), glucose ($75{\sim}281mg%$) and sucrose ($7{\sim}28mg%$). Major organic acids were malic acid (225 mg% in Kabjubaeknok (Jun. 4th)) and tartaric acid (189 mg% in Kabjubaeknok (Jun. 4th)). Predominant free amino acids were hydroxy-L-proline(25.33 mg% in Weolhasi), L-citrulline (58.83 mg% in SangjuDungsi (May 280)) and L-threonine (11.88 mg% in SangjuDungsi (May 280)). Major phenolic compounds in the persimmon flowers were caffeic acid ($1,946{\mu}g/100 g$ in Kabjubaeknok (Jun. 4th)), p-hydioxybenzoic acid($418{\mu}g/100 g$ in SangjuDungsi (May 29th)) and protocatechuic acid($181{\mu}g/100 g$ in Kabjubaeknok(Jun. 1st)). The results suggest that persimmon flowers be potential materials as useful food ingredients.
