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,. | Available online at Myi Science Direct ELSEVIER Food Chemistry 105 2007 1188-1194 Analytical Nutritional and Clinical Methods The nutrients of exotic mushrooms Lentinula edodes and Pleurotus species and an estimated approach to the volatile compounds Necla Caglarirmak Celal Bayar University Saruhanli College Food Technology Department Saruhanh Manỉsa Turkey Received 5 December 2006 received in revised form 17 February 2007 accepted 17 February 2007 Food Chemistry locate foodchem Abstract Texture nutritive values and volatile compounds of Lentinula edodes Pleurotus ostraetus and Pleroutus sajor-caju mushrooms were determined.

These mushrooms can contribute nutrition for protein and vitamin daily requirements. The mean mineral values of Pleroutus species mg kg wb were Zn Fe P Ca K Na respectively.
