Abstract

Supercritical fluid extraction has been employed as a green alternative for the obtaining of extracts provided of bioactive constituents from defatted Assai waste. The effects of process parameters on the resulted overall extraction curves were evaluated using a spline model, which adjustable parameters used to analyze the extraction behavior were the time span periods for the constant and falling extraction rates, i.e., t(CER) and t(FER), and the extraction rate for the constant extraction period, M-CER (or b(1)). The mathematical modeling was performed using an alternative algorithm implemented in MS Excel, which was able to provide reliable fittings comparable to SAS software. Although no report has been found to be compared to our economic evaluation findings, the costs of manufacturing (26.20-4.88 USD/kg extract) obtained in this work are competitive in the market, since the selling price of similar products worldwide is over 80.00 USD/kg of extract.
