Optimization of Fermentation Time for Iranian Black Tea Production
The optimum fermentation times of black tea manufactured by two systems of Orthodox and CTC (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly polymerized substances and total liquid colour during the fermentation stage. Optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولAntioxidant activity of black tea vs. green tea.
Dear Editor: A recent article by Leung et al. (1) reported that drinking black tea has benefits equal to those of drinking green tea in terms of their antioxidant capacities because theaflavins present in black tea possess at least the same antioxidant potency as catechins present in green tea. As reported in related studies (2–4), it is clear that a group of theaflavins (TF) in black tea, spec...

متن کاملEffects of dried Rose Petals (Rosa damascena) on the antioxidant capacity of Green and Black Tea
The health benefits of green and black tea are mainly associated with their antioxidant potential and phenolic compounds. The present study aimed to evaluate the effects of dried rose petals (Rosa damascena) on the antioxidant capacity of green and black tea. Antioxidant capacities of tea and rose infusions were assessed using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2-azinobis-3-<...
