“…For example, the evaluation of geographical and cultivar origins of extra-virgin olive oil (the most valuable class of olive oil) received great attention [3,41,42], with the added aim of finding possible adulterations [43,44]. De Flaviis et al [45] performed an in-depth study on wheat (based on PCA and PLS-DA) to evaluate the factors influencing the VOC's profile (genetic, soil, weathering and altitude of farming). Cervellieri et al [46] used a GC-MS-eNose to discriminate Italian wheat pasta from pasta produced with mixtures of wheat from different origins.…”

Instrument automation, technological advancements and improved computational power made separation science an extremely data-rich approach, requiring the use of statistical and data analysis tools that are able to optimize processes and combine multiple outputs. The use of chemometrics is growing, greatly improving the ability to extract meaningful information. Separation–multidetection generates multidimensional data, whose elaboration should not be left to the discretion of the operator. However, some applications or techniques still suffer from the lack of method optimization through DoE and downstream multivariate analysis, limiting their potential. This review aims at summarizing how chemometrics can assist analytical chemists in terms of data elaboration and method design, focusing on what can be achieved by applying chemometric approaches to separation science. Recent applications of chemometrics in separation analyses, in particular in gas, liquid and size-exclusion chromatography, together with field flow fractionation, will be detailed to visualize the state of the art of separation chemometrics, encompassing volatile, soluble and solid (colloidal) analytes. The samples considered will range from food chemistry and environmental chemistry to bio/pharmaceutical science.

“…Differences in pedoclimatic conditions, resulting from cultivation in different places and at different altitudes, seem much more important than wheat genetics in influencing the volatiles profile of kernels ( De Flaviis et al, 2021 , 2022a ); the place of wheat cultivation could thus impart to this crop distinctive quality traits.…”

“…The results of recent studies showed that it is possible to classify wheat according to their origin (species, variety, area of cultivation) based on their flavour profile ( De Flaviis et al, 2021 , 2022a , 2023 ) and that differences in wheat variety and cultivation site could affect the volatile organic compounds (VOCs) profile of wheat beers ( De Flaviis et al, 2022b , 2022c ). These results confirm those of other authors ( Alvim et al, 2017 ) who reported that the volatile profile of beer is more influenced by raw materials, such as malt and hops, and the method of production than by the kind of fermentation.…”

“…In other crops, such as teas and apples, cultivation at high altitude results in a change in the volatiles profile in comparison with cultivation at low altitude, 10,11 whereas in coffee, grapes, and olives, the cultivation at high elevation affects both the abundance of selected volatile compounds and the aroma profile of their products 12‐14 . Recent studies have shown that wheat cultivation at high altitudes does not necessarily result in a low yield and poor commercial quality 15 and that it could determine a distinctive flavor profile, as high‐altitude‐induced stresses trigger the formation of several sensory‐active volatiles, among which terpenes seem to play the major role 15‐17 …”

BACKGROUNDClimate changes associated with global warming are increasingly affecting the quality of cultivated crops. Cultivation at different altitudes and similar latitudes may offer an extraordinarily useful opportunity to obtain a diversificated dataset of climate variables and to further investigate their effect on crop quality. This study evaluated the effect of climate indices – temperature, rainfall precipitation and solar radiation data – on commercial parameters and the volatile organic compound (VOC) profile of wheat at harvest.RESULTSThree common and durum wheat varieties, including two heritage wheats, were sown in experimental fields sited at three altitudes for 3 years consecutively, and they were analyzed for their yield, grading parameters, and VOC profiles. The datasets were processed by partial least squares regression (PLS‐R) and the results indicate that summer days (SU25) and diurnal temperature range (ΔT) are the climate indices mainly responsible for the VOC profile changes in both common and durum wheat. Accumulated growth degree days (GDD), consecutive dry days (CDD), and accumulated solar radiation (ASR) induced species‐specific responses. Terpenes represented the chemical class of VOCs most affected by stresses, followed by ketones and alcohols, which were affected by CDD, GDD, and ASR.CONCLUSIONThis study showed a selective response of wheat to abiotic stresses associated with climate variables in terms of VOC synthesis. Its findings may be relevant in several fields, from plant ecology to agronomy and food quality, with implications for local economic strategies. © 2023 Society of Chemical Industry.
