Abstract

Presented are compositions that can be used as protective coatings for agricultural (e.g., food) substrates. The compositions can comprise a compound of Formula I:and an additive, wherein the variables m, n, q, r, Ra, Rb, R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, R11, R12 and R13 are defined herein. The protective coatings formed from the compositions can be used to prevent food spoilage due to, for instance, moisture loss, oxidation, or infection by a foreign pathogen.

First claim

1 . A method of protecting harvested produce, comprising:
providing a mixture comprising a composition in a solvent; and applying the mixture to a surface of the harvested produce to form a coating over the produce, the coating being formed from the composition and being less than 3 microns thick; wherein the coating serves to reduce a rate of mass loss of the harvested produce by at least 10%.

2 . The method of claim 1 , wherein the coating is greater than 0.05 microns thick.

3 . The method of claim 2 , wherein the composition comprises a compound selected from the group consisting of monoacylglycerides, fatty acids, esters, amides, amines, thiols, carboxylic acids, ethers, aliphatic waxes, alcohols, organic salts, and inorganic salts.

4 . The method of claim 3 , wherein the composition comprises a monoacylglyceride.

5 . The method of claim 4 , wherein the composition further comprises an organic salt.

6 . The method of claim 1 , wherein the solvent comprises water or ethanol.

7 . The method of claim 1 , wherein the composition comprises a first monoacylglyceride compound and a second monoacylglyceride compound different from the first monoacylglyceride compound.

8 . The method of claim 7 , wherein a carbon chain length of the first monoacylglyceride compound is different from a carbon chain length of the second monoacylglyceride compound.

9 . The method of claim 8 , wherein the composition further comprises an organic salt.

10 . A method of protecting an agricultural product, comprising:
providing a solution comprising a composition dissolved in a solvent, the composition comprising at least one of 1-monoacylglycerides, 2-monoacylglycerides, fatty acids, esters, and organic salts; applying the solution to a surface of the agricultural product; and removing the solvent to precipitate the composition and form a protective coating over the agricultural product, the coating being less than 3 microns thick; wherein the coating serves to reduce a rate of mass loss of the harvested produce by at least 10%; and the coating is substantially free of visible residues.

11 . The method of claim 10 , wherein the composition comprises a 1-monoacylglyceride having a first carbon chain length and a 2-monoacylglyceride having a second carbon chain length different from the first carbon chain length.

12 . The method of claim 10 , wherein the composition comprises a first 1-monoacylglyceride having a first carbon chain length and a second 1-monoacylglyceride having a second carbon chain length different from the first carbon chain length.

13 . The method of claim 12 , wherein the composition comprises an organic salt.

14 . The method of claim 12 , wherein the solution comprises a carboxylic acid.
