Özet

This study aimed to experimentally investigate the effect of sugar syrup additions on quality measurements of honey and to detect adulteration. For that purpose, two different pure blossom honey samples were adulterated by directly mixing 0%, 5%, 10%, 20%, 30%, 40%, and 50% of commercially available glucose-fructose corn syrup and maltose corn syrup. In this regard, key physico-chemical properties like moisture, pH, free acidity, proline, diastase number, color (L, a, b and Delta-E), electrical conductivity, HMF, sugar profile (glucose, fructose, sucrose and maltose), and C4 sugar analysis were tested. The results of the individual analysis of moisture, pH, free acidity, proline, diastase number, color, electrical conductivity, and HMF failed to detect sugar syrup adulteration. However, when principal component analysis (PCA) was utilized to analyze the data gathered from these tests, adulterations at all-syrup ratios (5-50%) were successfully detected.
