Crystallization of honey at -20°C

Honeys from different regions of the province of Buenos Aires were stored at -20°C, and factors that affect crystallization were analyzed. Crystals were observed by light microscopy. Firmness, adhesivity and viscosity of the samples were measured. Honey was characterized by determining the water act...
