Abstract

Abstract: Background: 5-Hydroxymethylfurfural (5-HMF) is a neo-formed contaminant arising in foods during thermal processing, especially under acidic conditions. Exposure to 5-HMF is inevitable for human beings since it is widespread in foods, including honey, bread, beer, coffee, fruit juices, and black garlic. The many studies published to date have shown that 5-HMF displays diverse effects on human health, including carcinogenicity, neoplastic transformation, and hepato- and nephrotoxicity, and antioxidant activity. Therefore, reducing the amount of 5-HMF in foods has become an important food safety issue. Scope and approach: This review introduces the formation and biological effects of 5-HMF in food, and summarizes the methods developed in recent years for mitigating 5-HMF formation or for removing 5-HMF from foods, including ultraviolet irradiation, phytochemical addition, yeast fermentation, vacuum treatment, microwave heating, non-thermal processing, and formula adjustment. Key findings and conclusions: According to the available evidence, the effects of 5-HMF on health are closely correlated with dose, though more research is needed to clarify many aspects. In addition, the testing of food sensory attributes should be critically considered when evaluating 5-HMF elimination approaches in order to increase their applications in the food industry. Highlights: The mechanisms of formation of 5-HMF are summarized. The positive and negative effects of 5-HMF on human health are discussed. This review advance of the processing approach to reduce 5-HMF in foods.
