a b s t r a c tPolysaccharides production from the fruiting body of Tricholoma matsutake was carried out using enzymeassisted extraction methodology. Response surface methodology (RSM), based on a five level, four variablecentral composite design (CCD), was employed to obtain the best possible combination of extractiontemperature (X1: 54–66 ◦C), extraction pH (X2: 3.6–4.4), extraction time (X3: 2.4–3.6 h), and complexenzyme (the ratio of papain:pectinase:cellulase was 1:1:1) amount (X4: 1.6–2.4%) for maximum polysaccharidesproduction. The experimental data obtained were fitted to a second-order polynomial equationusing multiple regression analysis and also were analyzed by analysis of variance (ANOVA). The 3-Dresponse surface plot and the contour plot derived from the mathematical models were applied to determinethe optimal conditions. The optimum extraction conditions were: extraction temperature of 61.8 ◦C,extraction pH of 4.14, extraction time of 3.2 h, and complex enzyme amount of 2.1% (w/v). Under theseconditions, the experimental yield of polysaccharides was 7.53±0.26%, which is well in close agreementwith the value predicted by the model
