Description of Research Interests
Dr. Singh's research is focused on value-added processing using various emerging technologies. Projects include developing processes for peanut blanching and crispy products using radiant wall technology. He is also developing processing protocols for various foods using radio frequency heating technology, and micronization followed by microencapsulation of phytochemicals from fruits. Additionally, these projects require physical and chemical characterization of products and properties of key ingredients.
