Detection of Undeclared Addition of Corn Syrup to Apple or Orange Juice

Poor harvests have a number of impacts on the food production chain, including increasing the likelihood of adulteration of some foodstuffs.

This is particularly pertinent right now in the UK, where farmers have suffered the 2nd worst harvest on record as a result of unusual weather conditions.

Significant economic incentives to adulterate apple or orange juice with less expensive sugar solutions, the simplest method of extending a fruit juice, known to be practiced by less scrupulous people, is to add inexpensive sugar and dilute with water to rebalance the sweetness.

However, the addition of inexpensive corn syrup or cane sugar to apple or orange juice can be detected by carbon-13 analysis.

See Example Laboratory Report*

This analysis detects undeclared additions of corn syrup, including high fructose corn syrup, to apple or orange juice.

Our team conduct carbon-13 analysis to the standards required by the Association of Official Analytical Chemists (AOAC) Method 981.09 – Carbon ratio mass spectrometric method for detection of corn syrup in apple juice and Method 982.21 – Carbon ratio mass spectrometric method for detection of corn syrup in orange juice.

We require a minimum of 10 ml of apple or orange juice, or 1 gram of concentrate, to be supplied for analysis. Our laboratory reports include carbon-13 content of the juice, as determined by duplicate analysis, and an interpretation of the outcome of the analysis.
