Article Abstract
The objective of this study was to discrimination the cultivar, growing region, and geographical origin of rice () using a mass spectrometry-based electronic nose (MSE-nose). The inside-needle dynamic extraction (INDEX) system was used to concentrate the samples for MSEnose, following which the ion fragment data obtained were used to perform discriminant function analysis. Discriminant functions 1 and 2 readily separated all 16 cultivars of rice sampled. It was also confirmed that MSE-nose could distinguish the region in which rice cv. and were grown, likely due to variation in environmental factors, such as soil and climate. Finally, it was confirmed that MSE-nose could be used to detect the geographical origin of rice, discrimination Korea rice from Japanese rice. Therefore, this simple and rapid technique is of value for discriminating the cultivar, growing region, and geographical origin of rice.

Fruit and fruit-based products are a valuable source of essential nutrients, critical for food security, and drive economic productivity with minimal inputs. The significant rise in global demand for high-quality imported fruit and fruit-based products reflects a shift in consumer awareness and interest in the products origin and potential health-promoting bioactive compounds. Analytical techniques such as liquid chromatography, gas chromatography, inductively coupled plasma techniques, isotope-ratio mass spectrometry (IRMS), near infrared (NIR) spectroscopy, visible near infrared (VIS-NIR) spectroscopy, hyperspectral imaging (HSI), mid-infrared (MIR) spectroscopy, Raman spectroscopy, nuclear magnetic resonance (NMR) spectroscopy, fluorescence spectroscopy, terahertz spectroscopy, dielectric spectroscopy, electronic nose (e-nose), and electronic tongue (e-tongue) coupled with supervised and unsupervised chemometrics can be employed for traceability, authentication, and bioactive profiling of fruit and fruit-based products.

Denisovans have yet to be directly associated with a hominin cranium, limiting our understanding of their morphology and geographical distribution. We have attempted to retrieve DNA from a nearly complete Middle Pleistocene cranium from Harbin (>146 ka), northeastern China. Although no DNA could be retrieved from a tooth or the petrous bone, mitochondrial DNA (mtDNA) could be isolated from dental calculus.
