Chemical Ingredients of Fresh and Dry Wild Mushrooms from Bosnia and Herzegovina

Abstract

<p>Many species of wild mushrooms are used as a delicacy in the diet, but data on their nutritional value and the effects of their storage on nutritional values are rare. The aim of this study was to determine the content of Free Amino Acids (FAAs), total carbohydrates, vitamin C, and total anthocyanins in six wild mushroom species collected in Bosnia and Herzegovina. Results showed that the drying of mushrooms does not have much influence on the presence of essential and non-essential amino acids. Mushrooms are an excellent source of amino acids whether they are fresh or dry. The total carbohydrate content varied between 12.25-62.75 mg g^-1 for fresh mushroom extracts and 40.98-167.24 mg g^-1 for dry mushroom extracts. The total carbohydrate content in dry mushrooms is significantly higher than in extracts of fresh mushrooms. The vitamin C content of mushrooms varied between 0.02-1.95 mg g^-1 for fresh mushrooms and 0.0-0.63 mg g^-1 for dry mushrooms. A lower vitamin C content was found in dry mushrooms, which can be affected by the method of drying mushrooms. The total anthocyanins content varied between 0.39-0.66 mg CGE mL^-1 for fresh mushroom extracts and 0.10-0.19 mg CGE mL^-1 for dry mushroom extracts. Lower total anthocyanins content was found in dry mushroom extracts, probably due to the destruction of anthocyanins by drying. Our research shows that selected wild edible mushrooms, fresh and dry, have considerable nutritional potential. However, further research is needed on both other nutrients and anti-nutrients in these mushrooms to support their nutritional dominance.</p>
