Course Objectives

 

To improve their knowledge in Extraction Technology which is a valuable skill. To familiarise with different advanced extraction techniques developed to date

To improve the existing practical knowledge of students in extraction technology.

To introduce more sophisticated and sensitive extraction techniques such as Supercritical Fluid Extraction and Microwave assisted extraction techniques.

Learning Outcomes

 

This is another vital course which will impart new skill in the students. By learning this course students will know about different extraction techniques and can perform their own extractions using different herbal materials. While experimentation students will choose specific extraction technique depending on their formulation and medicinal plants used for extraction. Hands on experience on advanced instruments will enable them to perform well at industrial level which improve strength of their CV.
