What it is

Orange blossom is the flower of citrus trees, most often Citrus × aurantium, distilled into orange blossom water.

What it tastes like

On the nose: lavender, citrus, rose, floral. Among its measured molecules: 1,3,8-p-Menthatriene, 2-carene, cis-β-Ocimene, alpha-cadinol, D-limonene.

Every one of its 15 compounds carries a paper the library can cite.

  36.79% of the reference hydrosol (absolute content 1.5674 mg/kg), the largest constituent; odour activity value 7124.55 in that hydrosol and 9427.73 / 15778.182 / 14134.545 in the other three, the highest OAV in the study — Xie et al. 2024, Molecules (Table 1 (Analysis of the volatile components of CAVA IH), row 'Linalool'; Table 6 (OAV analysis of volatile components of hydrosols), row 'Linalool')
