Non-centrifugal raw cane sugar (NRCS) is a minimally processed product from sugarcane (Saccharum officinarum L). This product contains phytochemical and nutritional compounds that benefit human health. Despite these advantages, NRCS commercialization is hindered by a lack of knowledge about its composition and, consequently, the absence of quality standards. Studies associating the nutritional composition of sugarcane varieties and their genuine products have not yet been found in the literature, and understanding this relationship can help establish quality standards for this product. Therefore, this study evaluated the mineral nutritional composition of genuine derivative NRCS produced from two sugarcane varieties obtained under different agronomic conditions at two stages of maturation to verify the relationships between raw material and the product. The obtained sugarcanes, juices, and bagasse, as well as the produced sugars, were analyzed for mineral content, such as calcium, magnesium, potassium, phosphorus, sulfur, iron, manganese, copper, and zinc, using inductively coupled plasma optical emission spectrometry. Most mineral constituents of sugarcane are in the juice in direct proportions to those in raw sugarcane. Thus, minimally processed food derivatives have nutritional characteristics equivalent to the raw materials. Consumption of NRCS contributes to meeting daily requirements for essential nutrients such as magnesium, copper, potassium, and manganese. For manganese, 25 g of NRCS, like the one produced in this study, can fulfill 22 to 76 % of an adult male's daily mineral requirements. The variation observed in the four NRCS samples, obtained from the same sugarcane variety under different maturation and agronomic conditions, was 250 %. This variation makes establishing quality parameters for mineral or ash content difficult. Therefore, setting mineral content levels for NRCS is inappropriate, as this parameter naturally depends on the raw material.
非离心原蔗红糖（NRCS）是一种从甘蔗（Saccharum officinarum L）中提取的低加工产品。该产品含有有益于人类健康的植物化学物质和营养成分。尽管有这些优点，但由于缺乏对其成分的了解，NRCS 的商业化受到了阻碍，因此也没有质量标准。目前还没有文献研究将甘蔗品种的营养成分与其真正的产品联系起来，了解这种关系有助于为该产品建立质量标准。因此，本研究评估了两种不同农业条件下成熟度不同的甘蔗品种所生产的真正衍生 NRCS 的矿物质营养成分，以验证原料与产品之间的关系。对获得的甘蔗、蔗汁和蔗渣以及生产的糖进行了矿物质含量分析，如钙、镁、钾、磷、硫、铁、锰、铜和锌，使用电感耦合等离子体光学发射光谱法。甘蔗中的大多数矿物质成分都存在于汁液中，与原甘蔗中的成分呈直接比例。因此，低加工食品衍生产品具有与原料相当的营养特征。食用 NRCS 有助于满足镁、铜、钾和锰等必需营养素的日常需求。对于锰，25 克 NRCS，如本研究中生产的 NRCS，可以满足成年男性 22%至 76%的日常矿物质需求。在从同一甘蔗品种在不同成熟度和农业条件下获得的四个 NRCS 样本中观察到的变化为 250%。这种变化使得难以确定矿物质或灰分含量的质量参数。因此，设定 NRCS 的矿物质含量水平是不合适的，因为该参数自然取决于原料。
