Study of the mineral composition and color intensity of some honey samples circulating in the Libyan market

الملخص

Considering that honey is a complete food rich in minerals, which are an important reason for honey acquiring different colors, this study aimed to determine the levels of sodium (Na), potassium (K), lithium (Li), calcium (Ca), and barium (Ba) in six samples. Sample H1 was recorded the highest concentrations of these elements (12.7, 48.8, 1.4, 8.8, and 17.3 ppm), respectively. UV spectroscopy results showed that sample H3 had the highest iron concentration (7.05 mg/100 g), while H6 had the highest phosphorus level (317 mg/g). In addition to the elemental analysis, the honey color was evaluated using the Pfund scale, a commonly used standard that measures the color and intensity of honey samples on a spectrum from light to dark. Sample H6 recorded the highest Pfund value and density (134.73 mm Pfund and 805 mU), showing a dark amber color. In contrast, sample H3 was recorded the lowest Pfund value and density (52.29 mm Pfund and 204 mU), showing a light amber color.
