US 10,517,310 B2 · Plant extract compositions and methods of preparation thereof

Abstract

Embodiments described herein relate generally to plant extract compositions and methods to isolate cutin-derived monomers, oligomers, and mixtures thereof for application in agricultural coating formulations, and in particular, to methods of preparing plant extract compositions that include functionalized and non-functionalized fatty acids and fatty esters (as well as their oligomers and mixtures thereof), which are substantially free from accompanying plant-derived compounds (e.g., proteins, polysaccharides, phenols, lignans, aromatic acids, terpenoids, flavonoids, carotenoids, alkaloids, alcohols, alkanes, and aldehydes) and can be used in agricultural coating formulations.

Claims26

Dependent claims

A method of treating an agricultural product, comprising:

obtaining a composition comprising plant-derived fatty acids;
functionalizing the fatty acids by esterification to form fatty acid esters, the fatty acid esters comprising monoacylglycerides;
causing the monoacylglycerides to be added to a solvent, thereby forming a mixture;
and
causing the mixture to be applied to a surface of the agricultural product to form a protective coating from the monoacylglycerides over the agricultural product.

2 more elements

A method of treating an agricultural product, comprising:

obtaining a composition comprising a first group of plant-derived fatty acid esters;
transesterifying the first group of fatty acid esters to form a second group of fatty acid esters different from the first group of fatty acid esters, the second group of fatty acid esters comprising monoacylglycerides;
and
causing the monoacylglycerides to be applied to a surface of the agricultural product to form a protective coating from the monoacylglycerides over the agricultural product.

1 more element

A method of treating an agricultural product, comprising:

obtaining a composition comprising monoacylglycerides, wherein the monoacylglycerides are formed by transesterification of plant-derived fatty acid esters;
and
causing the composition to be applied to a surface of the agricultural product to form a protective coating from the monoacylglycerides over the agricultural product.

Dependencies are inferred from the claim text.
