He explains: "Most red wines go through a long maceration process that extracts all the color, tannins and flavor from the skins, and there's not much left for the distiller to work with".
The study shows that the UAEE could be employed to enhance the quality of must, reduce the time during the maceration process of juice or wine.
The 32 (two factors and three levels) factorial design, was applied to determine the best time and drug/solvent proportion to maximize the fl avonoid content in the hydroethanolic extract by maceration process.
The aim of this paper was to study and optimize the dynamic maceration process to obtain Matricaria chamomilla L., Asteraceae, inflorescences extracts with optimum flavonoid content and antioxidant activity using a multivariate approach.
In conclusion, the results validate the technological conditions of the maceration process to produce an optimized bioactive herb extract for the development of analgesic and anti-infl ammatory phytopharmaceuticals using 70 °GL ethanol, a plant to solvent ratio of 12.5% (w/v), and ten days of maceration.
In this work, the 25 2 fractional factorial design was selected in order to study how the factors of a dynamic maceration process influence the responses of total flavonoids, total phenols, quercetrin and afzelin contents, and antioxidant activity in extracts from C. langsdorffii leaves.
At the end of the maceration process, when equilibrium has been reached, the solution is filtered by passage through a special press.
The highest extraction yield in maceration process was obtained from processed chamomile flowers first class, while unprocessed chamomile flowers first class and processing waste show no significant differences (p < 0.05) between obtained extraction yield.
In maceration process, the ethanol was chosen as the solvent based on its environmental-friendly characteristics, low cost and its ability to enhance the extraction of target compounds from vegetable materials.
Instead, darkness in rosé is usually a matter of skin-contact time; the longer the maceration process, the darker and more tannic a wine, not sweeter.
