Abstract: In various implementations, methods may be implemented to extract pectin from citrus peel. The methods may include using a mild organic acid, an enzyme, or a mild organic acid/enzyme combination, to extract at least a portion of the pectin from the citrus peel. The methods may further include using high temperature and a short extraction time. In some implementations, no additional water is added, other than the water necessary to originally prime the system. The methods may further involve pressing the citrus peel or fruit waste to reduce the moisture content before adding the acid, enzyme, or acid/enzyme combination. In some implementations, the extracted pectin may be provided as a concentrated liquid or may be combined with cellulose and/or hemi-cellulose to form a composite ingredient.
