Minimally refined brown sugar (MRBS) is a brown sugar derived from sugarcane that has a low glycemic index. This study aimed to determine and compare the antioxidant contents and nutritional and physicochemical properties of MRBS, refined sugar (RS), and brown sugar (BS). In addition, the toxicity of these sugars was evaluated via in vitro cytotoxicity method and by using a zebrafish model. Results showed that MRBS was better than the two other sugars because it has a lower moisture content and higher ash content. The contents of potassium and manganese of MRBS were higher than those of the two other sugars. Surprisingly, MRBS also contained selenium, which was not detected in RS and BS. The major phenolics in MRBS are 4‐hydroxybenzoic acid, chlorogenic acid, protocatechuic acid, trans‐Ferulic acid, and apigenin. All sugar solutions and their antioxidant‐containing extracts were not cytotoxic to 3T3‐L1 adipocytes.

最低精制红糖和其他糖的抗氧化活性、营养和理化特性以及毒性

最低精炼红糖（MRBS）是一种从甘蔗中提取的红糖，血糖指数较低。本研究旨在测定和比较 MRBS、精制糖 (RS) 和红糖 (BS) 的抗氧化剂含量以及营养和理化特性。此外，通过体外细胞毒性方法和使用斑马鱼模型评估了这些糖的毒性。结果表明，MRBS 比其他两种糖更好，因为它具有较低的水分含量和较高的灰分含量。 MRBS中钾和锰的含量高于其他两种糖。令人惊讶的是，MRBS 还含有硒，而在 RS 和 BS 中未检测到硒。 MRBS 中的主要酚类物质是 4-羟基苯甲酸、绿原酸、原儿茶酸、反式阿魏酸和芹菜素。所有糖溶液及其含抗氧化剂的提取物对 3T3-L1 脂肪细胞均没有细胞毒性。
