This invention discloses an aroma fitter for fenugreek tincture based on key aroma components and synergistic aroma characteristics, and its applications. Based on analytical studies of the aroma components and aroma characteristics of high-quality fenugreek tincture, the aroma fitter identifies key aroma characteristics such as caramel sweetness, freshness, fruitiness, nutty aroma, roasting aroma, and sourness, and determines the contributing characteristic compounds and their synergistic proportions within each aroma characteristic. The composition contains key components such as acetic acid, trans-2-pentenal, propyl butyrate, phenethyl acetate, 2-hexanone, ethyl palmitate, benzaldehyde, 2,5-dimethylpyrazine, and 3-hydroxy-4,5-dimethyl-2(5H)furanone, which are precisely formulated to achieve a high degree of consistency with natural fenugreek tincture in aroma structure and olfactory characteristics. This invention not only provides a realistic and layered aroma fitter formulation but can also be applied to the food and daily chemical industries, providing stable and harmonious fenugreek characteristic aromas, thus possessing significant practical application value.
