Caracterização bromatológica de oito linhagens de Lentinula edodes (Shiitake) cultivadas em toras de Eucalyptus grandis

Abstract

Lentinula edodes is high quality food which is rich in proteins, vitamins, and minerals and poor in calories and fat. However, its nutritional value is variable according to the strain grown, processing after harvest, development stage of basidiomata, and substrate used. Thus, the objective of this paper was to carry out the bromatological characterization of basidiomatas from eight (LE-95/01, LE-95/02, LE-95/07, LE-96/17, LE-96/18, LE-98/47, LE-98/55 e LE-96/13) L. edodes strains, whole or in parts (stalk and pileus), produced in E. grandis logs. We verified that both the L. edodes strains and parts of basidiomatas analyzed influenced nutritional responses of the samples. The stalk presented the highest raw fiber averages and the lowest rawprotein averages. The pileus presented the highest ash averages. For all basidiomatas evaluations, the highest averages concerning raw protein contents were obtained for the strains LE-95/07, LE-96/17 and LE-96/18. The highest raw fiber average was obtained for the L. edodes strain LE-96/13. The lipids content of the pileus and the stalk did not vary among L. edodes strains.
