DNA Testing Identifies Ingredients In Foods

Modern DNA sequencing techniques have been turned toward creating a highly sensitive, quantifiable analysis of animal, plant, and microbial substances present in foodstuffs. In pilot studies, the researchers were able to use their new DNA method to detect the presence of a 1% content of horse meat in products and to determine the actual amount with a high level of precision. The researchers even found slight traces of the DNA of added mustard, lupin, and soy in a test sausage prepared for calibration purposes, something that could also be of interest with regard to allergy testing of foods.  read more
