Article Abstract
In this study, eight types of non-centrifugal raw cane sugar (NRCS) were produced from two sugarcane varieties at two stages of maturity. The sucrose/reducing sugar ratios (sugar index - SI) of the original juices and the possible NRCS styles, molded and granulated, were evaluated, as were the morphologies via scanning electron microscopy (SEM), sugar compositions via nuclear magnetic resonance spectroscopy (H NMR), and crystallinities via X-ray diffraction (XRD). Data analysis revealed that the styles of genuine NRCSs highly depend on the sugarcane maturity stage. Specifically, sugarcane juices with SI values less than 13 produced NRCSs with less than 69 % crystallinity, indicating an exclusively molded style. Thus, this research suggests that evaluating juices on the basis of the sugar index enables the prediction of the NRCS quality standard. In addition, the need for further studies to incorporate moisture as a quality parameter for NRCSs is highlighted.

Processed brown sugar is produced by combining non-centrifugal cane sugar (NCS), raw sugar, and molasses. The present study aimed to examine the effects of NCS and raw sugar blending (10%:90%, 50%:50%, 75%:25%, and 90%:10%) on color traits, non-volatile and volatile compounds, retronasal aroma release, and sensory profiles of processed brown sugar, and hence, its flavor quality. The International Commission for Uniform Methods of Sugar Analysis (ICUMSA) color index and the +L* (brightness) and +b* (yellowness) color spaces were gradually altered upon the addition of raw sugar, with strong Pearson's negative correlations between the ICUMSA value and both color space indices (r = -0.

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.

Raw cane sugars have been claimed to be rich in natural phenolic compounds which, in contrast to refined sugar, may increase the nutritional value of foods and contribute to the development of healthier foods and diets. The use of non-refined cane sugars in food formulation seems an interesting option since they provide natural antioxidants with sucrose still being the major sugar present, minimizing the loss of technological properties. However, substitution of refined sugar could imply an undesired impact on physicochemical and sensory properties, conditioning consumer's acceptance.
