Summary: | The invention relates to the technical field of polysaccharide modification, and discloses a preparation method of deacetylated gulcomannan and a product thereof, the preparation method comprises the following steps: mixing gulcomannan with an ethanol solution, and carrying out swelling treatment to obtain a swelled mixed solution; mixing the swelled mixed solution with an alkaline solution, and carrying out deacetylation reaction to obtain a deacetylation product; carrying out washing treatment on the deacetylation product to remove redundant alkaline solution, and then carrying out dehydration treatment to obtain a washing product; and carrying out drying treatment on the washing product to obtain the deacetylated glucomannan. According to the preparation method of the deacetylated gulcomannan and the product of the deacetylated gulcomannan, provided by the invention, the acetyl in the gulcomannan is at least efficiently removed, so that the water-holding capacity and the viscosity of the gulcomannan are re |
