Abstract

The present disclosure relates to a method for protecting stored agricultural dry products during storage, consisting of a controlled release system of essential oils and a shell for allowing oil diffusion in vapour phase towards the outer atmosphere without direct contact of the support material with stored products. This system is characterized by being suitable for use within containers for protecting stored dried agricultural plant products for a long period of time, in particular more than 4 weeks, more preferably more than 8 or 12 weeks.

First claim

The invention claimed is:

1. A method of enhancing long-term protection of an agricultural product, comprising:
storing the agricultural product in a dried form; and
exposing the stored agricultural product to an essential oil, wherein the essential oil includes both eugenol and pulegone, wherein the agricultural product is stored for at least four weeks.

2. The method of claim 1 , wherein the agricultural product is stored for at least eight weeks.

3. The method of claim 1 , wherein the combination of the eugenol and the pulegone have a concentration of at least 40 weight percent of the essential oil.

4. The method of claim 1 , wherein the stored dried agricultural product comprises at least one of a cereal, a pulse, and a nut.

5. The method of claim 1 , wherein the stored dried agricultural product comprises at least one of rice, a bean, maize, rye, whey, wheat, and a nut.

6. The method of claim 1 , wherein the essential oil includes at least one of a stabilizer, an antioxidant, and a food dye.

7. The method of claim 6 , wherein an antioxidant is added to the essential oil and the antioxidant added includes at least one of butylated hydroxytoluene, ascorbyl palmitate, calcium disodium ethylenediamine-tetraacetate, sorbic acid, 4-Hydroxymethyl-2,6-di-tert-butylphenol, monoglyceride citrate, 2,4,5 trihydroxybutyrophenone; tertiary butylhydroquinone, and 2,4,5-Trihydroxybutyrophenone.

8. The method of claim 1 , wherein the essential oil is derived from a plant.
