Abstract
Compositions containing 1,3-propanediol and an extraction product are provided, and the 1,3-propanediol in the composition is biologically derived. Also provided are processes for extracting an extract from a source. These processes include providing an ester of 1,3-propanediol and mixing the 1,3-propanediol ester with the source. This serves to extract the extract from the source into the ester. The processes also include separating the source from the ester and extract. Also provided are compositions containing an ester of 1,3-propanediol and an extraction product. In these compositions, the ester can have at least 3% biobased carbon.
