Glycerides and fatty acid mixtures and methods of using same

摘要

Green compositions and technologies are provided. In an embodiment, the present invention provides a method of separating a first material from a second material. For example, the method can comprise mixing the first material and the second material in a slurry with a beneficiation composition. The beneficiation composition can comprise one or more glyceride and fatty acid mixtures extracted from an ethanol process. Air bubbles can be provided in the slurry to form bubble-particle aggregates with the first material and the bubble-particle aggregates can be allowed to be separated from the second material.

1. A method of separating a first material from a second material, the method comprising the steps of:
mixing the first material and the second material in a slurry with a beneficiation composition, providing air bubbles in the slurry to form bubble-particle aggregates with the first material, and allowing the bubble-particle aggregates to be separated from the second material; wherein the beneficiation composition comprises an extract, the extract having been extracted from an ethanol process and comprises a mixture of a fatty acid and at least one glyceride, the composition further comprises carotenoids in a concentration of at least 250 micrograms per gram of the sum of grams of glycerides plus grams of fatty acid, and optionally the composition further comprises one or more component selected from the list consisting of: linoleic acid, phytosterols, tocopherols, hydroxycinnamate steryl esters, lutein, and zeaxanthin, and any combination thereof.
