abstract
Our research group has an extensive work in the chemical characterization of wild
mushroom species from the Northeast of Portugal. This region is one of the European
regions with higher wild edible mushrooms diversity, some of them with great
gastronomic relevance. In Europe, they are collected for consumption being a good source
of digestible proteins, carbohydrates, fibers and vitamins.
The present work reports the nutrients {fatty acids and sugars) and non-nutrients
{phenolic acids) present on the wild species most appreciated in the Northeast of
Portugal: Boletus edulis, Cantharellus cibarius, Lactarius deliciosus and Macrolepiota
procera. Fatty acids and sugars were obtained by GC-FID and HPLC-RI, respectively [1-3];
Phenolic acids were analysed by HPLC-DAD-ESI/MS [4]. Furthermore their nutritional value
was accessed through the composition in macronutrients and energetic value.
Boletus edulis gave the highest energetic contribution and MUFA {mainly oleic acid)
content; Cantarellus cibarius revealed the highest moisture and proteins levels; Lactarius
deliciosus showed the highest ash, fat, SFA {mainly due to the specific contribution of
stearic acid), sugars (total contribution of mannitol and trehalose) and phenolic acids
{mainly p-hydroxybenzoic acid) contents; Macrolepiota procera gave the highest levels of
total carbohydrates and PUFA.
It was concluded that the most appreciated wild mushrooms have different nutrients and
non-nutrients profiles and concentrations. This report contributes to the elaboration of
nutritional data bases of the most consumed species, allowing comparison between them.
