Сигурен ли си, че хмф-то трябва да е до 4. На прима виста ако не ме лъже паметта допустимото хмф е до 30. Не се сещам сега къде съм го гледал, но тази цифра ми се върти из главата. Провери си пак информацията за допустимите нива.

Цитат от тук: http://www.extension.org/pages/28844...n#.Vcy11GDN2SoHMF (hydroxymethylfurfural) is formed in honey and high fructose corn syrup (HFCS) at high temperatures due to acid-catalyzed dehydration of hexose sugars, with fructose more prone to its formation. HMF above 30 ppm (parts per million) is considered toxic to honey bees. HFCS with such levels of HMF has been found to cause high mortality in cage studies (LeBlanc et al., 2010), as well as higher mortality than bees infected with Nosema ceranae (Z.Y. Huang, unpublished data). Beekeepers using HFCS for bee feeding should pay special attention to storage conditions, although many times, the batch from the supplier might have already become “bad” due to high temperatures either during transportation or storage.
Some honeys are not toxic to bees, but to humans. A good example is honey from tutu (Coriaria arborea), which has caused fatalities in New Zealand.
