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.
微精炼红糖（MRBS）是一种源自甘蔗的红糖，其血糖生成指数较低。本研究旨在测定并比较微精炼红糖、精制糖（RS）和红糖（BS）的抗氧化成分以及营养和理化性质。此外，通过体外细胞毒性方法并使用斑马鱼模型评估了这些糖的毒性。结果表明，微精炼红糖优于其他两种糖，因为它的水分含量较低且灰分含量较高。微精炼红糖的钾和锰含量高于其他两种糖。令人惊讶的是，微精炼红糖还含有硒，而在精制糖和红糖中未检测到。微精炼红糖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脂肪细胞均无细胞毒性。
