Description
Samal Yeganeh-Zare leads a 2026 study on spotting fake apple juice concentrate sweetened with cheaper syrups. Pure concentrate was mixed with fructose syrup, glucose syrup, and date concentrate. The team measured acidity, sugars, organic acids, and minerals, then used statistical methods to sort pure from adulterated samples.
Fifteen measures were used for classification after reducing the data set. The best sorting, at 100 percent correct, came from just three minerals: sodium, potassium, and copper. Acidity and total sugar best showed the type of added syrup, while malic acid and ascorbic acid best showed how much was added. The method could support routine checks for juice fraud.
