Enzymatic process for the production of GLA concentrate

Enzymatic process for the production of GLA concentrate

Technology Description

The invention is the production of concentrated gamma-linolenic acid (GLA) from borage oil using a simple enzymatic process. It is both a method to create the concentrated oil and a concentrated GLA oil material. The method utilizes simple lipase mediated enzymatic hydrolysis to concentrate GLA as either an acylglyceride or free fatty acid. The GLA concentrate can be sold as a food ingredient or cosmetic ingredient depending on the form.

Applications

Does not require the use of organic solvents, therefore making it more environmentally friendly and safer for consumption
High yield of concentrate from enzymatic production allows for scaling up for industrial production
Production of a highly concentrated GLA (43-45%) oil for use in dietary supplement

Advantages

Simple process
Short reaction times
No need for additional solvents
Low amount of enzyme required
Provides high yields
Available as free fatty acid, available as acylglyceride
Available as 43% GLA concentrate, available as 45% GLA concentrate

Stage of Development

This is a mature stage in product development, and therefore some work needs to be done to transfer the technology from this stage into a product that can be sold commercially.
