Parametric Optimization Route of Oil Extraction from Seed: A Review

Abstract

Abstract Over the years, oil extracted from seeds has been employed as a skincare product, food, perfumes, biodiesel, soap and so much more. With the advent discovery of biodiesel, reliance on fossil fuels like petro-diesel has reduced drastically, as alternative diesel which burns in engines without the emission of greenhouse gases and less air pollution are being considered. Biodiesel production using seed oil is a means of converting waste to wealth because they are less expensive, biodegradable, and easily accessible. The use of seed oil for the production of alternative renewable energy can be achieved through extraction and the quality and quantity can be increased by the optimization of the process variables adopted for extraction. In this review paper, the different oil extraction method such as the conventional and the recent techniques will be evaluated as well as the downside and benefits of the extraction techniques, experimental designs employed for the optimization of seed oil alongside the impact of desired process variables on the amount and quality of the oil. Several studies have been conducted as regards seed oil extraction by adopting various techniques. However, the choice of a technique suitable for oil extraction with reasonable oil yield and good quality is very paramount and this is ultimately dependent on the type of seed and on whether the oil required is on a small- or large-scale basis. Optimization of process variable for extraction of seed oil will help save cost and improve the quality and quantity of seed oil.
