“…NCSs vary in minerals and VOCs for several reasons such as their production origin and processing methods [ 8 , 13 ]. In our previous studies, we confirmed the importance of minerals and VOCs in determining the NCS quality [ 1 , 8 , 11 , 14 ].…”

“…This MS-e-nose approach allows for non-targeted volatile profiling without chromatographic peak separation requirements and provides digital fingerprints from the acquired mass spectra of the volatiles. The MS-e-nose profiles of the NCSs were analyzed using a GERSTEL ChemSensor (GERSTEL, Mülheim, Germany) on an Agilent 7890A-GC-5975C MS system equipped with an Agilent G1888 HSS autosampler (Agilent J&W) [ 1 , 8 ]. Briefly, 3 g of NCS was placed in a 20 mL vial, and the headspace was extracted at 80 °C for 10 min and then pressurized into the GC injection port at 11 psi for 0.3 min The injection temperature was set at 250 °C, and the injection split ratio was 1:10.…”

Non-centrifugal cane sugar (NCS) is an unrefined dehydrated form of sugar syrup produced worldwide. To date, there is a lack of differentiation in the key nutrients and flavor qualities of NCS products among countries, which makes it difficult for interested parties to select NCSs suitable for their needs. This study aimed to evaluate the minerals and volatile organic components (VOCs) in NCS products from Japan and ASEAN countries. Mineral components were determined using inductively coupled plasma atomic emission spectroscopy (ICP-AES). VOCs and their aroma profiles were examined using gas chromatography–mass spectrophotometry (GC-MS) and MS-e-nose analyses, respectively. The total minerals content in Japanese NCSs ranged from 228.58 to 1347.53 mg/100 g, comprising K, Ca, Mg, P, and Na (69.1, 16.6, 7.9, 4.5, and 3.2%, respectively); their average total amounts were as high as those of Malaysia and Indonesia origins (962.87, 984.67, and 928.47 mg/100 g, respectively). Forty-four VOCs were identified, of which concentrations of pyrazines, furans, and pyranones varied significantly among the NCSs. Additionally, the MS-e-nose analysis provided a multivariate differentiation profile of the NCS products based on differences in the intensities of the VOC ion masses. Nine statistical clusters were presented, wherein certain NCS products of ASEAN origin had volatile profiles comparable to those of the Japanese products. These outcomes suggest that the origin of production greatly influences the mineral and VOC compositions of NCS, affecting their quality traits.
