Abstract

We could detect the specific gene of sugar beet (Beta vulgaris) from honey produced by sugar of sugar beet using the ultra-rapid real-time PCR (UR-qPCR). In our knowledge, it is the first report in the world that PCR detection of sugar beet-specific gene from adulterated honey. Through extracting the DNA (using CTAB method) from sugar and honey of sugar beet and using the UR-qPCR, sugar beet-specific DNA sequence could be amplified quantitatively until $10^0$ molecules of initial template. By using nested PCR and DNA sequencing, its specificity was confirmed. DNA sequence was matched 100% with mitochondria gene of sugar beet. This finding that trace DNA in adulterated honey could be genetically analysed, would be used as a decisive evidence for the authenticity test of honey.
