JOURNAL OF ANIMAL AND PLANT SCIENCES-JAPS(2022)
摘要
20 honey samples from district, Balochistan (Pakistan) were studied for their physiochemical, biochemical and antioxidant potential. During the study, pH, ash content, moisture, total fat, sugar content, reducing and non-reducing sugars, vitamin C, Vitamin A, flavonoids, polyphenols and % DPPH scavenging activity were monitored. The pH of the samples was between4.0 -5.0, having mean +/- SD values of 4.5 +/- 0.1. The moisture and ash content had an average value of 17.4 +/- 0.7 g/100g and 0.142 +/- 0.0 g/100g respectively. The fat content had range of values from minimum to maximum 0.12 -0.49 g/100g with mean +/- SD of 0.297 +/- 0.11. Total sugar content varied between 66.2 -71.8 g/100g with mean and S.D 68.88 +/- 1.7. The sucrose content ranged between 0.60 -4.28 g/100g with mean +/- SD 1.93 +/- 0.8 while average value of fructose and glucose values were 36.84g/100g +/- 0.9 and 30.41g/100g +/- 3.00 respectively. All the tested samples showed very low content of Vitamin A while Vitamin C and flavonoids showed the average values of 112.45 +/- 9.8 mg/kg and 43.0 +/- 2.0 mg CE/kg respectively and polyphenols showed the average value of 748.76 +/- 31.6 mg GAE/kg with 6057.5 -887.2 mg GAE/kg min to max values. The % DPPH scavenging at 40mg/ml showed the values 61.8 -75.7 min to max with the average of 70.3 +/- 0.9. All the tested samples lie within the limits of international standard but Sample P4 showed the best results among all the 20 honey samples.
