About

Shahin obtained his BSc in 2000 in the field of food science and technology from the Islamic Azad University, Iran. He completed his MSc in 2009 in food biotechnology at the University Putra Malaysia (UPM). In July 2011 he commenced his PhD studies at the University of Otago, New Zealand.
Shahin is a student member of the New Zealand Institute of Food Science and Technology (NZIFST), Institute of Food Technologies (IFT), Riddet Institute Scholar, and the Royal Society of New Zealand. He has been the student representative of the (IFT) Nonthermal Processing Division for Asia-Pacific (2013-2014).

Project Outline

Classical extraction methods, such as low pressure solvent extraction (LPSE) are widely used to obtain hydrophobic bioactive compounds from plant sources. Although LPSE is a simple method, it has limited application in food processing as most organic solvents are banned from food product extractions, and they are costly, environmentally hazardous, and require expensive disposal procedures.

There is an opportunity for the development of an inexpensive and efficient extraction system to replace the use of LPSE techniques. This research aims to develop a new strategy for the extraction of hydrophobic bioactive compounds from plant materials. This study evaluates the effectiveness of o/w microemulsions as a potential alternative to replace the use of organic solvents for extracting β-carotene from carrot pomace.
