Essencial oils

Like the hydrolyzable tannins mentioned in another publication, essential oils are also by-products of secondary or special metabolism in plants. And with a focus on a subject that we repeat a lot because of such importance, which is the search for alternatives to antimicrobial growth promoters, which has caused bacterial resistance, essential oils emerge alongside organic acids and hydrolyzable tannins.

There is a difference between essential and functional oils. The functional ones are extracted from seeds or grains, while the essentials are extracted from the essence of the plant. The use of essentials in animal nutrition aims to improve intestinal flora by raising zootechnical indexes

Antibacterial action

Having better results in Gram-positive bacteria due to the less complex membrane, when in contact with the bacteria, it changes the permeability of the membrane, making it difficult to transport ions and collapse the production and use of energy.

Antioxidant

The presence of phenolic compounds in essential oils neutralizes free radicals preventing oxidative action. The oils rich in thymol and carcravol have greater antioxidant effects.

Some examples of essential oils

Cinnamon: The main active ingredients are cinaladeido, eugenol and linabol. It has antioxidant and antibacterial actions.

Oregano: It has carcravol and thymol as its main active ingredients. It has antibacterial and antifungal actions.

Thyme: It has carcravol, thymol and geraniol. Antibacterial, antifungal and antioxidant actions.

Although many plant species have active ingredients in common, their concentrations vary widely from species to species, which can be mitigated with the synergistic mixture of cinnamon and oregano, for example, among other combinations.
