Response surface methodology was applied to optimize the recovery of ergosterol from an agroindustrial residue of Agaricus blazei Murrill, by comparing conventional (heat-assisted extraction, HAE) and more sustainable nonconventional approaches (ultrasound and microwave-assisted extractions, UAE and MAE, respectively). A circumscribed central composite design was employed to optimize and describe the interactive effects among variables of the HAE, MAE (time and temperature) and UAE systems (time and ultrasound power), and their performances compared with the standard soxhlet extraction system. The optimum conditions were predicted as 150 min, 81.6°C for HAE, 30 min, 400 W for UAE, and 25 min, 134.6°C, for the MAE system. The UAE system was identified as the most appropriate technique to obtain extracts with the highest amount of ergosterol, followed by MAE and HAE. Overall, these results demonstrate the potential of using the fruiting bodies of A. blazei as a suitable source to obtain ergosterol-rich extracts, which can be used as an ingredient for various biobased industrial applications.

“…In this sense, several methods have been evaluated to extract bioactive compounds from acerola seed and peel (Table 3). On the one hand, Rezende, Nogueira, and Narain (2017) concluded that ultrasound is better in extracting anthocyanins, carotenoids, ascorbic acid, phenolic compounds, and flavonoids with acidified ethanol from acerola industrial processing residue (seed and peel), in comparison with shaking and maceration. On the other hand, de Oliveira et al (2009) concluded that a high concentration of functional compounds, mainly phenolics, were extracted with methanol using a Soxhlet system from acerola pulp and peels, with an extraction yield of 7.1%.…”

Tropical fruits represent one of the most important crops in the world. The continuously growing global market for the main tropical fruits is currently estimated at 84 million tons, of which approximately half is lost or wasted throughout the whole processing chain. Developing novel processes for the conversion of these byproducts into value‐added products could provide a viable way to manage this waste problem, aiming at the same time to create a sustainable economic growth within a bio‐economy perspective. Given the ever‐increasing concern about sustainability, complete valorization through a bio‐refinery approach, that is, zero waste concept, as well as the use of green techniques is therefore of utmost importance. This paper aims to report the status on the valorization of tropical fruit byproducts within a bio‐refinery frame, via the application of traditional methodologies, and with specific attention to the extraction of phenolics and carotenoids as bioactive compounds. The different types of byproducts, and their content of bioactives is reviewed, with a special emphasis on the lesser‐known tropical fruits. Moreover, the bioactivity of the different types of extracts and their possible application as a resource for different sectors (food, pharmaceutical, and environmental sciences) is discussed. Consequently, this review presents the concepts of tropical fruit biorefineries, and the potential applications of the isolated fractions.

“…Acerola (Malpighia emarginata D.C.) is a native fruit to Central and South America, with Brazil having among the largest acerola crops in the world. Despite its industrial potential, acerola processing generates a substantial amount of residues, loss of raw material, with great environmental, social and economic impact, generating up to a total volume of 40% of discarded residue (Silva, Santana & Koblitz 2010;La Fuente, Zabalaga, & Tadini 2017, Rezende, Nogueira, & Narain 2017.…”

This study was aimed at analyzing the reduction of antinutrients, preserving apparent phenolic compounds in acerola flour residue by employing drying techniques. The optimal drying conditions were then determined in the wet residue, analyzing antinutrient concentration and apparent phenolic compounds in the residue and subsequently in the acerola flour. The physicochemical characterization of the flour was carried out, determining its antioxidant activity, thereby assessing the impact of the drying process on the composition of volatile compounds. The optimal drying conditions were found for a temperature of 65ºC for 120 min, reducing water activity by 0.3 and moisture content by 13.89%, which are considered adequate conditions for flours. Carbohydrate content represented 68.72 g/100g, while proteins represented 12.55 g/100g of the centesimal composition of the flour. Significant reductions (p<0.5) of antinutrients were observed in saponins (35.9%), followed by phytates (32.8%) and condensed tannins (11.52%). Losses of 18.7% of apparent phenolic compounds were also observed. For volatile compounds, a significant loss of esters with a significant increase in alcohol content was noticed. Thermal processing reduced aroma complexity, but maintained important bioactive compounds, such as linalool and caryophyllene. In this regard, taking into account the results of the present study, the agro-industrial residue of acerola proved to be an alternative source of antioxidants with a reduced antinutritional impact and may be incorporated as an ingredient in the formulation of new food products. Moreover, this agro-industrial residue reduces the environmental impact caused by the fruit pulp processing industry.
