摘要：Melanoidins are Maillard products produced in the hydrothermal treatment of organic solid waste represented by food waste and sludge. Their effect on anaerobic fermentation is related to energy recovery efficiency. Based on the researches of melanoidins in food field, this review paper aims to improve the understanding of melanoidins in wastewater treatment and anaerobic fermentation. The formation mechanism of melanoidins is complex, and the molecular weight and structure are not systematic and standardized. During the Maillard reaction process, the basic characteristics of melanoidins are affected by the type of reactants, temperature, pH and the presence of metal ions. In addition, the physicochemical and biological properties of melanoidin itself involve the mechanism explanation of melanoid behavior. Antioxidant, antimicrobial and metal chelating abilities are related to the inhibition or promotion of melanoidins in anaerobic fermentation, but the specific mechanism (such as cytotoxicity or the effect on interspecific electron transfer) still needs to be further explored. Finally, the characterization of melanoidins can provide more accurate semi-quantitative information with the development of analytical technology. The colorimetric method, ultraviolet/visible (UV/Vis) spectrophotometry, excitation-emission matrix joint region integration method and parallel factor analysis method developed from the color and structure characteristics of melanoidins have become the commonly used characterization techniques. In summary, the formation mechanism, structure, and characterization of melanoidins in the process of thermal pretreatment, as well as their impact and improvement on subsequent anaerobic fermentation are still the key directions for the efficient utilization of organic solid waste resources. ? 2022, The Authors.
