Pistacia vera l. - Anacardiaceae - pistachio, (Echte) Pistazie, Pistazienbaum

Dioecious deciduous shrub, native to West and Central Asia, currently distributed throughout the Mediterranean basin, cultivated since ancient times.

„The kernels are often eaten whole, either fresh or roasted and salted, and are also used in pistachio ice cream, kulfi, spumoni, historically in Neapolitan ice cream, pistachio butter, pistachio paste and confections such as baklava, pistachio chocolate, pistachio halva, pistachio lokum or biscotti and cold cuts such as mortadella. Americans make pistachio salad, which includes fresh pistachios or pistachio pudding, whipped cream, and canned fruit.“

„Major volatile compounds of the fresh pistachio nuts were detected as α-pinene (15.53-48.57%), α-terpinolene (1.66-23.06%), limonene (3.15-30.04%), and β-myrcene (3.50-8.95%), respectively. Sensory flavor profile analysis (FPA) techniques demonstrated the common descriptors for fresh pistachio nuts as fresh hazelnut, fresh walnut, fresh apricot kernel, pine, wet wood, green, sour, sweet, bitter, astringent, milky, and oily.“

„VOC analysis shows that Argentinean pistachio nuts are rich in monoterpenes, mainly limonene (citrus, mint), α-pinene (pine, turpine), and 3-carene (lemon, resin)… Considering the study case, 97 % of aromatic and basic tastes in pistachio nuts could be explained by three VOCs, namely, limonene, α-pinene, and 3-carene.“

More than 69% of the total peak area (GC-MS) of volatiles of SPME extracts of fresh pistachio nuts was composed of (Z)-9-octadecanoic acid isomers. Other components were α-pinene (10.2%), β-myrcene (1.8%), limonene (1.4%), α-terpinolene (6.3%), azulene (0.1%), 2-decenal (0.6%), 2-octenal (0.7%), and 8-heptadecene (0.1%).

The potent odorants present in roasted pistachio aroma of Kerman (Spain) and and Fandooghi (Iran) varieties are almost the same (HS-SPME, GCO, AEDA 4:1). The main difference lies in the perception intensity of some of those compounds. There were 8 regions with the same FD of 1024 and 10 with FD 256. Highest FD factors of 1024 showed 2-methylbutanal / 3-methylbutanal (malty), unknown (earthy), octanal (citrus), 2-acetyl pyrroline (roasted nuts, corn), unknown (rubber, plastic), unknown (ruber, sulfur-like), unknown (anis-like), and guaiacol (smoky). Among the 10 flavor-active components with FD 256 were isobutanal (malty), (Z)-4-heptenal (fishy), 1-octen-3-one (mushroom), dimethyltrisulfide (sulfur-like), 2,3-diethyl-5-methylpyrazine / 3,5-diethyl-2-methylpyrazine (fatty, green-like), (E)-2-nonenal (paper-like), 2-methylbutyric acid / 3-methylbutyric acid (blue cheese, sweaty), benzyl alcohol (sweet), unknown (green pepper, earthy), and methyl laurate (fatty, flowery).
„The descriptive sensory analysis (DSA) showed that the roasted, chocolate/coffee, and nutty attributes were rated significantly higher in the Fandooghi variety, whereas the green attribute was significantly higher in the Kerman one.“
