Description
  • About thirty Czech honey and mead samples of various floral sources were characterized by the presence of electrochemically active compounds. Median value of total electrochemical activity in honeys corresponded to 1.7 % of BHA. The highest activity was found in unifloral buckwheat and milk thistle (Silybum marianum) honeys. Darker honeydew were significantly higher in reducing activity than nectar honeys only when the buckwheat and milk thistle samples were excluded. During mead production and storage, no significant changes in the levels of honey-derived antioxidants were observed; however, the activity can increase due to the addition of spices or hops. Changes in composition and concentration of reducing substances during thermal treatment (70-200 °C) were investigated for selected honeys both in models and meals. The heating increased the total reducing activity both in model systems by factors of 1.2-14 and, in honey roast pork, by 30-40 % in comparison with the roast pork recipe without honey.
