چکیده
انواع عسل دارای خواص فیزیکوشیمیایی و دارویی متعددی می‌باشد که این تفاوت بستگی به منشاء گیاهی، جغرافیایی، عوامل محیطی و گونه زنبور عسل دارد. در این تحقیق مقایسه خواص فیزیکوشیمیایی و فعالیت آنتی‌اکسیدانی عسل شوید تولیدی با دو روش فرآوری‌شده(پروسه‌ای) و روش بیولوژیک انجام گرفت. آزمون‌های فیزیکوشیمیایی شامل رطوبت، pH، اسیدیته، ویسکوزیته، رنگ سنجی، مقدار کل ترکیبات فنولی به روش فولین- سیوکالتیو و فعالیت آنتی‌اکسیدانی(DPPH) برای عسل شوید، عسل پروسه‌ای و بیولوژیکی حاوی عرق شوید، و عسل طبیعی شاهد ( پایه یونجه) انجام شد. نتایج نشان داد بیشترین فعالیت آنتی‌اکسیدانی در عسل طبیعی شوید (60/87 درصد) حاصل شد. عسل طبیعی یونجه دارای فعالیت آنتی‌اکسیدانی برابر با 43/62 درصد بود. اگر چه تولید عسل بیولوژیک نتایج مطلوبی نسبت به عسل پروسه‌ای و طبیعی نشان نداد ولی نتایج آزمون‌های عسل پروسه‌ای تفاوت مشهودی با عسل طبیعی نداشت(0/05>P). لذا تولید عسل پروسه‌ای یک روش موثر برای تولید عسل گیاهی با خواص دارویی متفاوت است. اما عسل بیولوژیک علاوه بر هزینه زیاد، دارای خواص آنتی‌اکسیدانی کمتری نسبت به عسل طبیعی و پروسه‌ای می‌باشد. عسل های تیره تر ‌دارای ترکیبات فنولی، فلاونها و فلاونوئیدهای بیشتر و در نتیجه فعالیت آنت اکسیدانی بیشتری بودند.

چکیده English

Honey types have many physicochemical and medicinal properties, depending on the herbaceous origin, geographic location, environmental factors, and honey bee species. In this study, the comparison of physicochemical characteristics and antioxidant activity of honey containing added Dill extract in the process and biological methods. Physicochemical tests including moisture, pH, acidity, viscosity, colorimetry, total phenolic compounds by Folin-Ciocalteu method and antioxidant activity (DPPH) for Dill honey, processed and biological honey including Dill extract, and natural honey (control i.e., Alfalfa honey ) were done. The results revealed that the highest antioxidant activity in natural honey was obtained (60.87%). Natural Alfalfa honey had antioxidant activity equal to 43.62%. Although the production of biological honey did not show favorable results with compared to natural honey, the results of processed honey did not significantly differ (P <0.05). Hence the production of processed honey is an effective method for producing honey with different therapeutic properties. But biological honey, in addition to its high cost, has lower antioxidant properties than natural and processed honey. Darker honey samples had higher amounts of phenolic compounds, flavones, and flavonols and increased antioxidant activity.
