Storage Stability and Thermal Stability of Hordeumin, an Anthocyanin Pigment from Barley
スポンサーリンク
概要
- 論文の詳細を見る
Hordeumin stored at -40 to -80℃ in 1% HCl-methanol suffered neither from color reduction nor discoloration. After heating at 80℃ for 60min, hordeumin showed a pigment retention rate of 100%. This characteristic is because the pigment is a composite high-molecular weight compound consisting of anthocyanins and polyphenols. It was determined, however, that discoloration and browning occurred more rapidly than color reduction during storage and heating of the pigment.
