Research Progress on Authenticity Discrimination and Detection Methods of Whole-Wheat Foods

Whole-wheat foods are rich in various nutrients. Long-term consumption of whole-wheat foods can prevent chronic metabolic diseases, which has become a new trend in the healthy transformation of the grain industry. However, a standard system for whole-wheat foods is currently lacking, so product quality in the market is uneven. Consequently, developing a rapid and accurate method for authenticity identification and quantitative detection of whole-wheat foods is important for standardizing the market order. In this review, we briefly introduce the definition, standards and current detection status of whole-wheat foods, set forth the basis for the use of the whole wheat marker alkylresorcinols for the quality evaluation of whole-wheat foods, and summarize the quantitative detection methods of alkylresorcinols. Finally, we give an outlook on the future prospects and advantages of nanomaterials and bionics technology in the detection of whole-wheat foods, aiming to provide scientific references for the authenticity discrimination and quantitative analysis of whole-wheat foods.
