Course Goal / Objective
By the end of this course, students will be able to explain the chemical structure, biosynthesis, production methods, quality characteristics, biological effects, and principles of safe use of essential oils; and compare their areas of application in food, cosmetics, pharmacy, aromatherapy, and agriculture. In addition, students will be able to evaluate the principal problems encountered in the standardization, quality control, and application processes of essential oils, and develop scientifically grounded solution proposals to address these issues.
Course Content
This course covers the definition and classification of essential oils; essential oil-bearing plants; biosynthesis and chemical composition; extraction and distillation methods; quality control and standardization; chromatographic analytical approaches; antioxidant and antimicrobial effects; applications in food preservation; cosmetic and dermocosmetic uses; pharmaceutical and aromatherapeutic applications; toxicity and safety assessment; legislation; industrial fields of use; and current research.
Course Precondition
No prerequisities.
Resources
The course notes are sent to the e-mails of the students.
