Synthesis of the Halal Fragrance Compound Menthyl p- Anisate from Fennel Oil

Abstract

Menthyl p-anisate is an ester compound which can be used as chemical base of halal fragrance. Synthesis of menthyl p-anisate from Fennel Oil has been conducted. p-an1sate acid was derivative of anethol from fennel oil that undergo oxidation process by KMnO4 at 40°C for 2 hours. Esterification with menthol carried out at 40°C for 7 hours. Identification and determination of structure compound of the product was analysed by spectroscopic methods (FTIR and GC-MS). Organoleptic evaluation of the fragrance was carried out by 20 semi-trained panellists. The result showed that identification of menthyl p-anisate using FTIR indicated the presence of C-O ester at 1223,41 cm−1 and 1180,44 cm−1; and C = O carbonyl at 1689.64 cm−1. However, methyl p-anisate was different from menthol which is shown by mass spectra with the absence of m/z 71 and m/z 57 peak. Organoleptic evaluation suggested that the menthyl p-anisate compound is in range of “fragrant” with score 4,90, “very sharp fragrant” with score 5,90, and acceptance in range of “preferred” with score 5,00. Thus, follow the conclusion that the compound exerted potent ability as chemical component in halal fragrant.
