Lipid Extraction for Halal and Toyyib Applications: Conventional and Emerging Methods

Efficient lipid extraction is vital for producing Halal and Toyyib food products, medicines, and cosmetics, necessitating techniques that adhere to Islamic dietary regulations. This chapter reviews conventional methods like mechanical pressing and hexane solvent extraction, emphasizing the importance of solvent selection and addressing challenges such as solvent residues and cross-contamination. Advanced methods like supercritical fluid extraction, enzymatic extraction, and ultrasound-assisted extraction offer benefits like improved lipid quality and reduced environmental impact, yet present challenges in ensuring Halal-compliant enzymes and solvents. We compare these methods based on factors like source material, desired lipid quality, available resources, and Halal requirements, highlighting the need to balance these elements for compliance. Ultimately, the chapter provides insights into developing sustainable lipid extraction methods that cater to the expanding Halal market, enabling informed decisions by researchers, manufacturers, and consumers.
