Finally, the authors express their heartfelt gratitude and indebtedness to their parents, siblings and friends for their encouragement and affectionate inspiration.
The research was conducted in different laboratories of Faculty of Agro-Industrial and Food Process Engineering, Dinajpur and in Institute of Food Science and Technology, BCSIR, Dhaka, Bangladesh. Locally collected fresh mushroom were cleaned with hot water containing 3% salt and 0.01% citric acid at 100°C for 3 minutes. Then they were chopped into small pieces and dried at 33±2° for 48 hours upto 9-10% moisture level. The dried mushrooms were grounded to make powder. Three samples of bread were prepared incorporating 5%,10% and 15% mushroom powder and another sample containing no mushroom powder was collected from market. The composition of mushroom powder and bread prepared incorporating various levels of mushroom powder were analyzed to determine the effects of various levels of mushroom powder in nutritional constituents and consumers’ acceptability. The bread containing 5% mushroom powder showed significantly better result for texture and overall acceptability parameters of consumer acceptability. In case of nutritional composition, the bread with 5% mushroom powder (16.04% moisture, 10.07% protein, 9.20% fat, 1.82% ash and carbohydrate 62.87%) was better than bread with no mushroom powder (17.31% Moisture , 9.46% Protein, 9.10% Fat, 1.63% Ash and 62.50% Carbohydrate) but below bread with 10% (9.36% moisture, 10.74% protein, 9.73% fat, 2.01% ash and carbohydrate 58.16%) and 15% (17.54% moisture, 11.40% protein, 10.10% fat, 2.20% Ash and 58.76% total carbohydrate) mushroom powder. By considering both nutritional composition and consumer acceptability, it was concluded that bread with 5% mushroom powder was the best sample having highest consumer acceptability. It was also observed that addition of more than 10% mushroom powders affect the baking quality and acceptability of the bread adversely.
Food fortification has been defined as the addition of one or more nutrients to a food to improve its quality for the people who consume it, usually with the goal of reducing or controlling nutrient deficiency.
Normal bread does not contain enough protein for human nutrition. Addition of mushroom powder is a cost-effective way to increase protein and other nutrient content in wheat bread. Taste and flavour of mushroom can...
