Abstract
Texture, nutritive values and volatile compounds of Lentinula edodes, Pleurotus ostraetus and Pleroutus sajor-caju mushrooms were determined. The volatiles have been found out with an estimation approach by carrying out gas chromatography and mass spectrophotometer (GS-MS) Library Catalogue comparison. Neither regular increase nor decreases were observed for the values of texture, moisture, ash and protein values of L. eddoes. While a decrease, negative correlation was seen in values of vitamin C, folic acid and niacin values from the first flush to fourth flush periods, there was no correlation in the values of riboflavin and thiamin. Average mineral values of Shiitake (mg/kg wet basis) were: Zn, 10.18; Fe, 5.69; P, 998.47; Ca, 64.55; Mg, 191.89; K, 2347.33; Na, 622.40, proximate composition, vitamin C, folic acid, niacin, B1, B2 were determined in Pleurotus mushrooms. These mushrooms can contribute nutrition for protein and vitamin daily requirements. The mean mineral values of Pleroutus species (mg/kg, wb) were: Zn, 11.18-9.31; Fe, 14.80-7.94; P, 998.47-716.31; Ca, 81.16-23.66; K, 2225.00-2687.00; Na, 750.77-773.67, respectively. The volatile compounds, typical esters which are found in the mushrooms, hydrocarbons and fatty acids derivatives were determined with estimated approach by comparing library catalog of (GS-MS). © 2007 Elsevier Ltd.
