The problem up to now however is that the seeds have a short shelf life because of their high protein and fat content and become rancid quite quickly.
A new study has found that adding oregano essential oil to the seeds preserves both their benefits and their freshness.
This pattern of using natural additives instead of synthetic ones is a new trend in the food industry aimed an increasing consumer demand.
The oregano oils helps to stop liquid oxidation in the roasted seeds and delays the development of rancid tastes.
In addition to preserving the seeds the oregano oil has its own positive affect by helping to relieve gastrointestinal disorders.
The study is published in the Journal of Food Science.
