Risk and Benefit of Natural and Commercial Dark Brown Sugars as Evidenced by Phenolic and Maillard Reaction Product Contents.

Products of dark brown sugar (DBS) from different production processes and raw materials may bring different risks and benefits to human health. Therefore, this study was aimed to evaluate the quality of natural and commercial DBS products. Results showed that physicochemical properties, including pH value, turbidity, and browning degree have no significant difference between natural and commercial DBS products. Total flavonoid content of natural DBS was found to be significantly higher than that of commercial DBS ( p < 0.05). Notably, the levels of harmful Maillard reaction products in natural DBS were significantly lower than that in commercial DBS as evidenced by analyses of methylglyoxal and fluorescent advanced glycation end products ( p < 0.05). However, the amount of acrylamide in natural DBS was significantly higher than that in commercial DBS. In conclusion, this study provides useful information for risk-benefit assessment of DBS products, which is helpful for food safety management.
