Introduction

Sethuraman Swaminathan is a notable inventor based in Bengaluru, India. He has made significant contributions to the field of carotenoid extraction and purification. With a total of 2 patents, his work focuses on developing efficient processes for isolating valuable compounds from natural sources.

Latest Patents

Sethuraman's latest patents include a process for the isolation and purification of carotenoids from marigold flowers. This innovative method allows for the extraction of carotenoid crystals containing lutein and zeaxanthin in specific weight ratios. The process involves contacting a plant source rich in lutein with hexane and extracting it at temperatures between 40°C to 60°C to obtain an oleoresin rich in lutein. Similarly, a plant source rich in zeaxanthin is treated under the same conditions to yield an oleoresin rich in zeaxanthin. These oleoresins are then mixed in various ratios and homogenized to create a mixed oleoresin. The subsequent hydrolysis and crystallization steps result in carotenoid crystals suitable for nutraceutical and food products.
