Physico-chemical Properties and Biological Activity of Honey from Two Districts of Tien Giang Province, Vietnam

Abstract

This study was conducted to determine the physico-chemical properties and biological activity of honey collected from the Tan Phu Dong and Cai Be districts of Tien Giang province, Vietnam. The results showed that the 19% and 20% moisture content honey from Tan Phu Dong district had viscosities of 1075 Cp and 1013.33 Cp, insoluble solid contents of 0.12% and 0.09%, acidities of 32.49 mg/1000 g and 30.49 mg/1000 g, diastase index of 4.5 Schade and 4.09 Schade, free reducing sugar content of 65% and 67%, HMF contents of 0.98 mg/100 g and 0.86 mg/100 g and antioxidant activity of 0.47 and 0.52 mg vitamin C equiv./mg dry wt, respectively. The honey from Cai Be district with 22% moisture content, viscosities, insoluble solid content, acidity, diastase index, free reducing sugar, HMF content and DPPH antioxidant activity displayed as 619 Cp, 0.119%, 46.41 mg/1000 g, 5 Schade, 60.28%, 0.38 mg/100 g and 0.45 mg vitamin C equiv./mg dry wt, respectively.
