Sandra Teresita Martín del Campo

I suggest to use an enzyme, a lipase to increase the level. If you expose to sun or light you can oxidize your fat also.

Atiqah Rusli

Thank you Sandra for the suggestion. I found an article said that by treat with lipase it will decrease the FFA value but if treat with lipase + palmitic acid it will increase the FFA value. I share the article with you as attached. Scroll to page 1495.
