Food samples had impurities that affect readings you should refine your analysis in terms of proper preparation of food samples for food analysis..The AOAC ( American Official.Agricultural Chemists had established methods as well as the AACC ( American associations of cereal chemist..Check their voluminous manuals specific to carbohydrate analysis..
