Variety traits

Taste and aroma — walnut

Juglans regia L.

Taste and aroma are key breeding traits for walnuts, determined by organoleptic evaluation and the chemical composition of volatile compounds. High product quality is characterized by the absence of bitterness, astringent aftertastes, and off-odors.

In the reference 38 varieties crop Persian walnut, where this is mentioned in the description.

In walnut breeding, taste is evaluated organoleptically using a scoring system, where a mild, nutty, and slightly sweet profile is considered the standard. Bitterness and astringency are indicators of low quality, often associated with oil oxidation due to improper storage conditions or premature harvesting.

The specific aroma of the walnut is formed by a complex of 17 significant volatile compounds, among which sotolon and (2E, 4E, 6Z)-nona-2,4,6-trienal play a key role. Maintaining these characteristics depends directly on adhering to harvest timelines and protecting the nuts from exposure to moisture and sunlight.
