In recent times, studies have shown the negative effect that synthetic preservatives have on mental health. Recently, various essential oils have been shown to be just as effective without the negative side effects, such as hyperactivity and various disorders of the immune system. Thyme oil in parsley performed very well. These essential oils also lower the risk of causing antibacterial resistance. To make consumption and use as a preservative easier, research is being done into making essential oils into edible films to be used in production of food.
- As Professor Yiannis Samaras points out, essential oils are not only cheap and effective, they also reduce the risk of antibiotic resistance.
- A 2014 study showed that essential oils were superior to commercial additives at preserving bread.
- The preservative benefits of essential oils can help reduce both food waste and the usage of synthetic additives.
“A noteworthy British study, in The Lancet, found that sodium benzoate used as a food additive or preservative posed too much of a risk for hyperactivity in children to go unnoticed.”
