Quality of Tobacco Seed Oil from <i>Voor-Oogst</i> Variety Using Ultrasonic-Assisted Extraction

Abstract

Tobacco seed of the Voor-oogst variety has a high oil content and is harvested as waste from tobacco plantations, but it has not been utilised optimally. The purpose of this research was to obtain the best quality oil from tobacco seed using ultrasonic-assisted extraction (UAE). Oil was extracted from tobacco seeds using ultrasonic waves with various extraction times (30, 60, and 90 minutes) and n-hexane solvent volume (100, 125, and 150 mL). The quality of the oil was determined based on the moisture content, acid number, and saponification number. An analysis using ANOVA was performed to identify the best quality of oil statistically. The highest yield from the extraction process was 23.38% oil from 90 minutes of extraction treatment and 150 mL of solvent volume. The extraction treatment using n-hexane solvent volumes of 125 and 150 mL had a similar yield based on ANOVA. The main fatty acid of tobacco oil was linoleic acid (54.10%), oleic acid (8.18%), palmitic acid (7.92%), and stearic acid (2.10%). Based on the high linoleic content, the Voor-oogst variety of tobacco seed oil has the potential to be applied in the fields of cosmetics and food supply.
