Influence of cultivation methods on the chemical and nutritional characteristics of Lentinula edodes

Abstract

Lentinula edodes (Shiitake) is an edible mushroom with excellent nutritional potential, aroma and flavor. It’s traditionally produced on wood logs, but this practice has been replaced by cultivation on axenic substrates (AS) made from different materials that are stored in plastic bags. This papper aimed to evaluate the nutritional composition of L. edodes grown on Quercus acutíssima (QA) and AS by correlating their chemical composition with the media on which they were grown. Culture media were analyzed for their density, moisture content, ash, extractives, lignin (soluble and insoluble) and holocelulose before L. edodes inoculation, as well as after the second consecutive harvest this mushrooms. The mushrooms from the second harvest of each culture media were characterized regarding their moisture content, protein, ash, lipids, dietary fiber (soluble and insoluble), α, β and glucanas total, carbohydrates and minerals. Mushrooms cultivated on AS showed higher protein content, macrominerals and lipids, when compared to mushrooms cultivated on QA. AS initially contained lower lignin content, less holocelulose and a reduced C:N ratio when compared to QA. The results showed that the composition of the culture medium influenced the nutritional composition of L. edodes mushrooms.

Protective effect of Agaricus bisporus mushroom against maternal and fetal damage induced by lead administration during pregnancy in rats

“…Our analysis revealed that the Ab contained trace amounts of toxic metals. The origin of the toxic metals may have been from the substrate where the mushroom was cultivated, (e.g., Bach et al, 2018). However, the levels detected were negligible and did not have any significant impact on our results, except for ALT enzyme; this biomarker isolated increased in the Ab group.…”

Kütük Yetiştiriciliğinde Misel Ekim Zamanı Ve Ağaç Türlerinin Shiitake Mantarının (Lentinula edodes) Verim Ve Kalitesi Üzerine Etkileri

“…MAZ×AT Farklı ağaç türlerine ait kütüklerden elde edilen shiitake mantarlarının protein ve mineral madde içeriklerindeki farklılığın ağaç türlerine bağlı olarak kütüklerin besin içeriklerindeki değişimden kaynaklandığı düşünülmektedir. Farklı tarımsal atıkların kullanıldığı yetiştirme ortamlarından elde edilen shiitake mantarının protein ve mineral madde miktarlarının farklı olması da ortamların içeriklerinin etkisinden kaynaklanmaktadır [4,25,41,42]. Mantarlarda element bileşimini, substratın kimyasal bileşimi ve özellikleri yanında, ortamın eser elementlerle kirlenmesi de etkilemektedir [43].…”

Composition and contents of fatty acids and amino acids in the mycelia of Lentinula edodes

“…Therefore, it is necessary to discover more ways to get high‐quality, healthier protein. Edible mushrooms provide high‐quality proteins and present more productivity and biological efficiency than animals as a protein resource (Fabiane et al, 2018). These mushrooms are rich in dietary fiber, minerals, and vitamins and have a low lipid content, abundant amino acids, and a high proportion of polyunsaturated fatty acids (Jonathan et al, 2013).…”
