After two days of conservation, it was found that the concentration of kampferol was 0.024 mg/100 g which was identical to the concentration of kampferol (0.024 mg/100 g) at +25°C. But in the case of refrigeration, the concentration of Kampferol was 0.023 mg/100 g at +6°C whereas the concentration of Quercetin was 0.027 mg/100 g dates. At 3-weeks of conservation, the mean concentration of Quercetin was 0.087 mg/100 g in Khalas dates while that of kampferol was 0.067 at +6°C. But at +25°C conservation temperature the concentration of kampferol reached to 0.45 mg/100 g as compared to Quercetin concentration of 0.045 mg/100 g. The research findings showed that date conservation at +6°C increased the concentration of flavonoids such as Kampferol and Quercetin. The study showed that date storage under chilled conditions can maintain higher levels of different flavonoids.]]>Abo-El-Soaud, A.A.,20032003Al-Farsi, M., C. Alasalvar, A. Morris, M. Baron and F.
