However, it is difficult using this method to disclose the honey adulteration with other high fructose syrup (HFS) from C3 plant (C3 HFS), such as rice, beet and cassava etc, because the difference of d13C‰ between C3 HFS and honey is too small to be used as a standard to prove the adul teration in honey (Krueger & Reesman, 1982). Recently, more researches have been focused on the carbohydrate profile of honey again, which is usually applied to control the botanical and geo- graphical origin of honey
