This study aims to identify factors that affect saffron quality in order to enhance the quality and production of saffron. Saffron samples were collected from 38 harvest sites at various altitudes (high, medium, and low) in Taliouine and Taznakht. Analysis of the content of safranal, crocin, and picrocrocin was carried out through spectrophotometry in the ultraviolet‐visible (UV–vis) according to the ISO 3632‐1:2011 standard. Saffron from high‐altitude sites was found to have the highest average content of picrocrocin (90.92 ± 5.98), safranal (28.57 ± 2.52), and crocin (208.37 ± 21.27), followed by that from medium‐altitude sites (87.59 ± 8.22, 27.09 ± 3.69, and 200.05 ± 19.86, respectively). Analysis of variance test showed that the quality of the saffron was influenced by the altitude and not by the species provenance. Principal component analysis (PCA) indicated that saffron containing the highest quantity of crocin was found to have the greatest coloring strength and consequently belonged to the first grade. Partial least squares (PLS) regression allowed finding a suitable preliminary model to predict the coloring strength from the absorbances. Overall, these findings can be used to improve the quality and quantity of saffron by developing the conditions of saffron cultivation, especially at high altitude. Novelty impact statement The investigation of Moroccan saffron showed that his quality is affected by the altitude and not by the provenance, and that the high altitude containing the first grade of saffron. The moisture content showed an effect on saffron quality. PCA identified a strong correlation between crocin, coloring strength, and saffron grade. Thus, the saffron with the highest amount of crocin had the highest coloring strength and therefore belonged to the first grade. PLS regression was successfully created as a preliminary model to predict coloring strength based on their absorbance data in these study areas.

“…Among the 80 compounds detected, most of them have been already reported in saffron from diverse geographical origins and obtained by various extraction and detection techniques [2,5,[11][12][13][14][15][16][17][18][19]. Seventeen VOCs were common to all the eight ecotypes, including hexanal (V12), heptanal (V18), limonene (V19), 2-pentylfuran (V21), nonanal (V37), 1,3,5,5-tetramethyl-1,3-cyclohexadiene (V38), β-isophorone (V39), benzaldehyde (V46), α-isophorone (V53), safranal (V57), 4-ketoisophorone (V59), 2,4-dimethylbenzaldehyde (V65), dihydrooxophorone (V69), nepetalactone (V74) 2-(butylthio) thiophene (V78), and 4-(3-methyl-2-butenyl)-4-cyclopentene-1,3-dione (V79).…”

“…They are generated from the degradation of lipophilic carotenoids during the stigmas' maturation and includes the ionone derivatives [18,21]. This group, detected in saffron regardless of its geographical origin, plays a crucial role in the synthesis of new compounds during the storage process and has been indicated as key aroma compounds, responsible for the herbaceous and floral notes in saffron [2,5,11,12,14,17,18]. In all the examined samples, excepting the RRWT ecotype, compounds of this group, including 6-methyl-5-heptene-2-one (V34), α-ionone (V53), dihydro-β-ionone (V70), trans-geranyl acetone (V71), β-ionone (V75), and dihydro-β-ionol (V77), were detected (Table S1).…”

The volatile profiles of eight saffron samples (seven cultivated and one spontaneous) grown in different geographical districts within the Campania region (southern Italy) were compared. Using headspace solid-phase microextraction coupled to gas chromatography–mass spectrometry (HS-SPME/GC-MS), overall, 80 volatiles were identified in the eight landraces. Among them, safranal and its isomers and other related compounds such as isophorones, which are not only key odorants but also pharmacologically active metabolites, have been detected in all the investigated samples. Principal Component Analysis performed on the volatiles’ compounds revealed that the spontaneous sample turned out to be an outlier. In particular, the volatile organic compounds (VOCs) profile of the spontaneous saffron presented four lilac aldehydes and four lilac alcohol isomers, which, to the authors’ knowledge, have never been identified in the volatile signature of this spice. The multivariate statistical analysis allowed the discrimination of the seven cultivate saffron ecotypes in four well-separated clusters according to variety. Moreover, 20 VOCs, able to differentiate the clusters in terms of single volatile metabolite, were discovered. Altogether, these results could contribute to identifying possible volatile signature metabolites (biomarkers) or patterns that discriminate saffron samples grown in Campania region on a molecular basis, encouraging future biodiversity programs to preserve saffron landraces revealing valuable genetic resources.
