As the result of establishment of brands for some farming districts in Japan, it is a big social issue that agricultural products of which geographical origins are camouflaged. To solve this problem, we have proposed a distributed system that identifies cultivated places of vegetables by using their trace element content as coresearch with agricultural chemists. This system records trace elemen...

This paper explores how language policy affects the socio-economic development of nation states through two channels: the individual’s exposure to and (in reference to an individual’s mother tongue) linguistic distance from the official language. In a cross-country framework the paper first establishes a robust and sizeable negative relationship between an official language that is distant from...

Pooled salivary gland samples are frequently used to ensure the sufficient amount of material for the experiments; however, this could mask an individual variability. Thus, we compared salivary protein profiles in seven colonies of three Phlebotomus species: Phlebotomus sergenti, Phlebotomus perniciosus, and Phlebotomus papatasi. Surprisingly, the individual profiles differed significantly betw...

In the present work, we have evaluated for first time the feasibility of APCI-MS volatile compound fingerprinting in conjunction with chemometrics (PLS-DA) as a new strategy for rapid and non-destructive food classification. For this purpose 202 clarified monovarietal juices extracted from apples differing in their botanical and geographical origin were used for evaluation of the performance of...

Near-infrared (NIR) spectroscopy in diffuse reflectance mode was explored with the objective of discriminating sea salts according to their quality type (traditional salt vs "flower of salt") and geographical origin (Atlantic vs Mediterranean). Sea salts were also analyzed in terms of Ca(2+), Mg(2+), K(+), alkalinity, and sulfate concentrations to support spectroscopic results. High concentrati...

Rapid near infrared (NIR) spectroscopic analysis models were developed to distinguish the geographical origin and determine the content of Polygonum perfoliatum L. The spectra of 94 samples of differing origin were recorded using two NIR instruments (Antaris II and Nicolet 6700). The spectral pretreatment methods used were the first-derivative (FD) and the standard normal variate correction (SN...

In connection with the growing consumer’s interest to Russian wines controlled place of origin PGI and PDO, most pressing issue is method their identification. One effective ways confirm wine's in world practice a comprehensive research elemental profile isotopic characteristics “light” elements using methods statistical analysis. We have selected 32 samples fresh grapes from various wine regio...
