Red rice has been proposed as a super-food. Accordingly, the nutritional properties (AOAC), as well as its chemical composition, including sugars (HPLC-RI), organic acids (UFLC-PDA), tocopherols (HPLD-FD), and phenolic compounds (LC-DAD-ESI/MSn), together with the main bioactive properties (antioxidant, cytotoxic, antiproliferative, and antibacterial activities), were evaluated to access its nutritional benefits and health improvement potential. The most abundant macronutrients found were carbohydrates (87.

In the present work, the effect of the cultivation process, in the field and under a controlled environment, on biochemical parameters by using commercial strains of were evaluated. The results obtained revealed that the strains cultivated in the field presented higher levels for most of the parameters evaluated (organic acids (20.5-48.

Portobello variety of Agaricus bisporus mushrooms, appreciated for its taste, makes it desirable to be eaten fresh and also as flour in soups and gravies. Gamma and electron-beam radiation at four doses (1, 2, 5, and 10 kGy) were used to analyze its preservation effect on Portobello mushroom flour. A proximate analysis, as well as the impact on fatty acids, tocopherols, soluble sugars, organic acids, and ergosterol profiles, were performed every 3 months, during a storage period of 1 year.

Supplementation of mushroom substrates has been linked to a higher resistance against insect pests, although few studies show the impact of this supplementation on the different agronomical parameters of mushrooms or even their chemical composition. In this work, the variation in the biological and chemical composition of oyster mushroom ( var. florida (Jacq.

Deficiencies of micronutrients, essentially vitamins and minerals, have mainly cause several illnesses, especially in children and women worldwide. Governments and world organizations have focused great efforts to address these shortcomings and improve the health of the populations. This malnutrition can be combated by fortifying basic foods that are consumed daily.

Seven types of wheat and rye flours were studied regarding their physical and chemical properties, as well as the presence of mycotoxins and microorganisms. The results revealed that flours presented moisture and ash contents below the recommended maximum limit. They also presented a low lipid content, which helps avoiding changes in the flours' smell and taste.

Mushroom production and consumption is increasing, but high perishability still represents a major commercial drawback. Besides increasing the product shelf-life, conservation processes should be innocuous to consumers. Therefore, the effects of gamma and electron beam radiation on chemical and nutritional composition of fresh samples of Agaricus bisporus Portobello (a highly commercialized species) were assessed.

The present work is aimed at developing nutraceutical formulations based on the mycelium of Agaricus bisporus and Pleurotus ostreatus, highlighting the potential of in vitro culture as a tool to improve the production of bioactive compounds, namely phenolic acids and ergosterol. The mycelia of both species were cultured in different solid and liquid media in order to compare the growth rate and yielded biomass. Fruiting bodies, mycelia and culture media were compared regarding the antioxidant activity, anti-inflammatory effects in RAW264.
