Quality Assessment of Nigerian Honeys Sourced from Different Floral Locations

Abstract

Comparative studies on the quality of honey obtained from different floral locations in Nigeria were investigated. Parameters such as physical properties, chemical, mineral, microbial contents and antimicrobial activity as well as organoleptic quality were evaluated. The results of the physico-chemical properties show the following range of values for acidity (1.36-1.55%), soluble solids (80.96-82.00%), specific gravity (1.41-1.44) and sweetness index (52.52-62.73). While the proximate values were: moisture (15.69-18.41%), protein (0.90-1.15%), fat (0.12-0.21%), ash (0.26-0.38%) and carbohydrate (79.94-82.71%). Potassium (55.31mg/100g) and calcium (5.14mg/100g) were the dominant minerals in the honey samples. The highest microbial count was observed in sample NSK (1.4±0.14x10 2 cfu/100g). There were no observable coliform growths in all the samples. All the honey samples exhibited antibacterial activities with clear zones that range from 2.05-6.10mm. Honey samples KAD and ABJ had the best overall acceptance scores of 8.49 and 8.27 respectively.

Assessment of essential minerals and physico-chemical analysis of floral origins fresh honey produced by Apis mellifera

“…(Abdulkhaliq and Swaileh, 2017) investigated potassium and sodium concentrations ranging from 183.86 ppm to 104.66 ppm, which are lower than the previous study. The findings agreed with those of (Agbagwa et al, 2011) and(Joel, 2014), who found potassium dominance in the honey. On the other hand, microelements such as Cobalt, Chromium, Manganese, Molybdenum, Nickel, Lead and Selenium were found in the normal range.…”
