Comparative study of physio-chemical analysis of fresh and branded honeys from Pakistan

الملخص EN

Honey is a nutritious substance produced by bees.

Its quality and nutritional value is of great importance for consumers.

Keeping this in view physicochemical and minerals determination as quality parameters of fresh floral Pakistani honeys produced by A.

mellifera and branded honeys was conducted.

The results of fresh honey indicated average means of Color as 48.78 mmPfund, pH 4.9, Total acidity 37.14 meq/kg, Moisture content 18.62%, Electrical conductivity 0.23 mS/cm, Ash content 0.49%, HMF content 30.85 mg/kg, Proline 365.84 mg/kg, Diastase activity 34.39(DN) and Invertase activity was 68.61(IN) comparable to honey standards.

Natural honey were rich in k+ (408.46 ppm) and Na+ (405 ppm).

Although Ca+ was very low.

Whereas, Co, Mn and Ba concentrations exceed the 1 ppm.

However, Pb, Cr, and Mo were unnoticeable.

Similarly, Color, pH, MC, EC, T.

Acidity, HMF, Proline, Ash content, Diastase and Invertase activity of branded honey samples average means found were 42.5 mmPfund, 5.05, 20.5%, 0.18 mS/cm, 15.34 meq/kg, 36.5 mg/kg, 181.6 mg/kg, 1.11%, 7.90(DN) and 36.97(IN) respectively.

The findings showed that fresh honey samples were good and of consumable quality as per honey standards than branded honey.

Higher HMF content and lower enzymatic activity in branded honey sample than the Codex standards revealed its either long or improper storage.
