Abstract

Objective: The aim of this study was evaluation of some physicochemical parameters and total phenolic compounds content of five Libyan honey samples that most commonly consumed in east Libya, Libya. Methods: Libyan honey samples included mono-floral (ziziphus louts; thymus capitatus; eucalyptus; Arbutus pavari) and multi-floral honey, were collected from local market in Benghazi city. The physicochemical parameters of all honey samples, including moisture content; ash content; electrical conductivity; optical density; pH; total acidity, free acidity, sugar contents and hydroxmethylfurfuarl, were measured. Results and Discussion: Some honey samples showed higher values of moisture content than the maximum permitted level of Libyan standard Legislation, but moisture content values were within the Codex Standard limit. However, the values of the other physicochemical parameters of Libyan honey samples were found to meet the Libyan Standard Legislation for honey. The total phenolic compounds content of the samples ranged from 97.67-123.50 mg gallic acid/100g of honey, with a mean value 109.64 ±11.93 mg gallic acid/100g. Conclusion: The values of physicochemical parameters of Libyan honey samples varied bases on the floral source, handling and storage condition. The high total phenolic compounds content indicates that the Libyan honey has a high antioxidant potential, especially Arbutus pavari honey.
