Proximate and Dietary Fibre Analysis of Mushrooms

Abstract

Quantitative analysis of nutritional components and dietary fibre in over-thirty species of mushrooms was accomplished. The average contents were as follows; crude protein: 24.4±7.62, crude fat: 4.3±2.10, crude ash: 8.3±2.67, Carhohydrate: 63.0±9.19, respectively (% in dry basis±S.D.). Neutral detergent fibre (NDF), acid detergent fibre (ADF), lignin, pectic substance and crude fibre (CF) were estimated to evaluate as dietary fibre (DF). The average contents of dietary fibre were as follows; NDF: 35.7±7.79, ADF: 14.3±4.71, lignin: 2.9i-1.34, pectic substance: 3.7±2.28 and CF: 9.7±3.40, respectively (% in dry basis±S.D.). Therefore, the average content of cellulose (ADF-lignin) was 11.4±4.63%, hemicellulose (NDF-ADF) was 21.4±7.12% and total DF (NDF+pectic substance) was 39.4±7.73%. The mean ratio of crude fibre to total DF was found to be about 5.7 for mushrooms, while being much smaller for vegetables.
