Abstract:
... Honey is a nutritious natural sweetener from honey bee-collected nectar from a variety of flowers. The health benefits and high value of honey, however, have motivated fraudulent acts of honey adulteration by either a direct or secondary inclusion of cheaper sweeteners. Therefore, stringent quality controls must be in place to ensure authenticity of honeys while safeguarding the wellbeing of consu ...
