Determination of amino acid content, fatty acid profiles, and phenolic compounds in non-conventional edible fruits of seven species of palm trees (Arecaceae) native to the southern half of South America.

The fruits of palm trees (Arecaceae) are a very important food source for fauna and for humans, despite the still incipient role of these fruits in conventional diet. Seven palm tree species (plus one variety) that are native to the southern half of South America located east of the Andes (Argentina, Paraguay, Uruguay, and the southern states of Brazil) were studied. For the first time, the fatty acid profiles of palm seeds and the content of both amino acids and phenolic compounds present in the pulp (yellowish fleshy mesocarps) of the fruits were determined.

Chemical features and bioactivity of grain flours colonized by macrofungi as a strategy for nutritional enrichment.

Agaricus blazei, Auricularia fuscosuccinea and Pleurotus albidus mycelia were obtained in solid-state cultivation (SSC), using grains (brown rice, canjica corn and wheat) as raw material. Colonized grain flours were analysed for their nutritional, physical and physico-chemical characteristics and biological activity in vitro. Wheat flour with P.
