Abstract
The objective of the present invention is to provide a water-soluble konjac potato extract with a simpler method. There is provided a water-soluble konjac potato extract comprising sterylglucoside, wherein the content of fatty acid ester is equal to or less than 500 mg/100 g, the content of phytosterol is equal to or less than 5,000 mg/100 g, and the content of glucosylceramide is equal to or more than 5,000 mg/100 g, obtained by separating and removing fatty acid ester and phytosterol from a konjac potato extract extracted with an organic solvent.
Claims6
A water-soluble konjac potato extract comprising sterylglucoside, with a content of fatty acid ester of equal to or less than 500 mg/100 g, a content of phytosterol of equal to or less than 5,000 mg/100 g, and a content of glucosylceramide of equal to or more than 5,000 mg/100 g.
A method of producing a water-soluble konjac potato extract, comprising
