| Abstract Crude polysaccharides of Lentinus edodes were extracted using homogenate method. Factors affecting the yield of crude polysaccharides were investigated and optimized by response surface methodology. The homogenate extraction method was compared with traditional heating extraction method. The antioxidant activity of crude polysaccharides from Lentinus edodes was evaluated. Results showed that, the optimal conditions of homogenate extraction were as follows: solvent pH, 10; liquid-solid ratio, 30: 1 (mL: g), extraction time, 66 s; number of extraction, 1. Under these conditions, the yield of crude polysaccharides was (13.2 ± 0.9)%, which was 29.82% higher than that of traditional heating extraction. Crude polysaccharides of Lentinus edodes had good... |

| Many studies have drawn attention to the occurrence and concentration of toxic elements found in the fruiting body of mushrooms. Some edible mushroom species are known to accumulate high levels of inorganic contaminants, mainly cadmium, mercury, and lead. There are about 2,000 known edible mushroom species, but only 25 of them are cultivated and used as food. In Brazil, the most marketed and consumed mushroom species are Agaricus bisporus, known as Paris champignon, Lentinus edodes, or Shitake and Pleurotus sp, also called Shimeji or Hiratake. In this study, the concentration of cadmium was determined in Lentinus edodes mushrooms from different cities in São Paulo state and some samples imported from Japan and China. The analyses were performed by graphite... |
