5.PHYSICO-CHEMICAL PROPERTIES OF HONEY PRODUCED IN THE CENTRAL REGION OF PUNJAB_ PAKISTAN By HAMMAD SHAFIQ1_ AZKA SHAHID1 AND MUHAMMAD ZAKRIA FARID2
Abstract
The aim of current study is to determine the physicochemical properties of
honey samples collected from the central region of Punjab province of
Pakistan. Ten samples were analyzed for several physicochemical parameters
including water activity, moisture, acidity, hydroxymethylfurfural (HMF),
soluble solids, electrical conductivity, ash contents, sugar content, mineral
content and color (L*, a*, b*). The average value for water activity is 0.588,
for moisture 17.36 %, for acidity 29.2 meq kg-1, for HMF 13.87 mg kg-1, for
soluble solids 80.6 °Brix, for conductivity 0.463 ?S cm-1, for ash content 2.12
g kg-1and for fructose and glucose is 384.0 g kg-1, 321.0 g kg-1 receptively .The
honey samples present a good level of quality because the physicochemical
values were in the range of approved limits (conforming to codex standards)
for all honey samples.
KEY WORDS: Honey, physicochemical characteristics, Sugars, Minerals.
