Non-digestible polysaccharides from edible mush-rooms may have immunomodulatory properties. Therefore,the availability of mushroom polysaccharides is relevant for research or industrial purposes, as polysaccharides may be used as functional food ingredients. Recently, a method using successive extractions to obtain mushroom polysaccharides was developed, but it is time-consuming. As a way to enablea fast and efficient extraction, a set of improvements was proposed, allowing for obtaining water-soluble polysaccha-rides in half the time of the original method. Similar yield, composition, molecular weight, homogeneity and conforma-tion of polysaccharides obtained demonstrated that the optimised method could be explored as a fast and efficient way to obtain water-soluble non-digestible polysaccharides from mushrooms.
