 "The edible seeds are referred to as cashew nuts. They are surrounded by a leathery shell (mesocarp), which is rich in liquid. This substance is an important raw material for resin. The liquid contains skin-irritant toxic compounds, which are removed by heating. The fleshy hypocarp, or cashew apple, is processed into jam and dried fruit."

 "Cashew apples have a sweet but astringent taste. This astringency has been traced to the waxy layer on the skin that contains a chemical, urushiol, which can cause minor skin irritation to areas that have had contact with it. It is almost identical to the astringency caused by the skin of a mango, which also contains urushiol. The astringency from mango skin can be mildly tasted in the flesh of mango fruit, just as the astringency of cashew apple skin can be mildly tasted in the flesh of cashew apples. In cultures that consume cashew apples, this astringency is sometimes removed by steaming the fruit for five minutes before washing it in cold water; alternatively, boiling the fruit in salt water for five minutes or soaking it in gelatin solution also reduces the astringency. When mixed in drinks or used as a flavoring, the astringency becomes highly diluted and typically causes no irritation to those without urushiol allergies." \\ "Cashew apples have a sweet but astringent taste.

 +Volatile compounds in a heated aqueous extract of cashew included (FID peak area %): Propanal (7.59), acetone (1.69), methylpropanal (30.48), 2-methylfuran (13.95), butanone (1.62), 2-pentanone (7.62), 3-methylbutanal (11.49), 2-methylbutanal (8.08), acetol (1.9), hexanal (0.35), methylpyrazine (0.68), dihydro-2-methyl-3(2H)-furanone (coffee furanone; 0.45), furfural (7.44), dimethylpyrazines (0.44), acetylfuran (0.49), benzaldehyde (0.24), 5-methylfurfural (0.42), phenylacetaldehyde (0.46). \\

 +"...Strecker aldehydes, including methylbutanal, 2-methylpropanal, and acetaldehyde, were at the highest concentration in roasted cashews. The Maillard reaction contributed to the formation of most of the volatiles in cashews from the 3 countries. There was also degradation of sugars to form furan-type compounds and oxidation of lipids to form alkanals such as hexanal." \\

 +"In cashew nuts, acetic acid and acetaldehyde contribute to a pungent aroma, and phenylethanol is responsible for sweet and floral aromas. The main aromas come from pyrazines and aldehydes. Pyrazines are responsible for a nutty aroma and aldehydes such as methylbutanal and 2-methyl propanal are responsible for a pleased aroma in many roasted foods. Lipid oxidation products such as hexanal and nonane are also contributed to green and herbaceous odors, while ethyl butanoate is responsible for sweet, fruity and cashew-like aromas." \\ 
 +Roasted cashews showed higher concentrations (μg/L) of organic volatiles than raw cashews. This is especially true for compounds like acetic acid, acetaldehyde, 2-methylpropanal, methylbutanal, methanol, ethanol, hexane, heptane, styrene, ethyl butanoate, acetone, as well as mono-, di- and trimethyl pyrazines. \\
