Using design, seven factors, namely, ethanol concentration, liquid:solid ratio (mL/g), sonotrode, amplitude (%), time, extractant pH, cycle, were studied.

The incorporation of artichoke bracts, a by-product processing, into pasta formulations represents an innovative approach to enhancing the nutritional and functional properties this staple food while promoting environmental sustainability. This study aimed evaluate impact powder (AP) enrichment (10% w/w replacement semolina) on technological, nutritional, antioxidant, sensory pasta. enriched (P-AP) was compared control (P-CTR) through comprehensive physicochemical analyses, including cooking performance, polyphenol characterization, in vitro digestion. Polyphenol analysis revealed that chlorogenic acid, dicaffeoylquinic acids, flavonoids accounted for 87% total identified phenolic compounds P-AP. Despite 42% reduction free polyphenols due cooking, digestion 47% increase polyphenols, attributed release bound polyphenols. Antioxidant assays (DPPH, ABTS, FRAP) confirmed significantly higher antioxidant capacity P-AP P-CTR. Additionally, exhibited lower predicted glycemic index (pGI = 56.67) than 58.41), beneficial feature blood glucose regulation. Sensory highlighted distinct differences between samples, with showing stronger vegetal, artichoke, legume-like notes, as well intensity bitterness astringency. While panelists rated P-CTR overall liking, maintained acceptable characteristics. These findings support valorization by-products production, demonstrating their potential enhance quality contributing circular economy.

Fuchsia hybrida (pena pena) and Alcea rosea L. (malvagoma) are predominant flowers in the “Horchata” infusion, a traditional beverage southern Ecuador, to which some medicinal properties attributed. However, there is very little published information about these two flower species. The current study aimed obtain dehydrated powders of determine their chemical composition, physicochemical technological properties, polyphenols, fatty acids profile. In both powdered flowers, carbohydrates predominated, with significant content dietary fiber fructose. fat was low, mainly comprising polyunsaturated fats (62% pena 52% malvagoma), presence omega-3 (C18:3n-3,6,9) omega-6 (C18:2n-6,9) acids, showing better n-6/n-3 balance malvagoma flowers. Pena highlighted by high anthocyanin ellagic acid amounts, whereas contains flavanones. conclusion, studied powder could be used formulation new foods or as source anthocyanins food colorants.
