Pulsed Electric Field Applications for the Extraction of Bioactive Compounds from Food Waste and By-Products: A Critical Review

Biomass, Journal Year: 2023, Volume and Issue: 3(4), P. 367 - 401

Published: Nov. 6, 2023

The food processing industry is a continuously developing sector that uses innovative technologies to efficiently process products. During processing, industries generate substantial amounts of by-products in the form waste materials. This consists organic matter rich bioactive compounds, such as polyphenols, carotenoids, and flavonoids. Improper management can adversely affect both environment human health, leading environmental pollution release greenhouse gas emissions. Thus, proper has become an urgent global issue. presence compounds (mainly flavonoids, anthocyanins, but also alkaloids, proteins, lipids, carbohydrates) holds potential transform them into valuable resources. Several sectors, including energy, have recognized source. Recently, much emphasis been placed on optimizing extraction yield through utilization environmentally friendly sustainable methodologies solvents. Pulsed electric field (PEF)-assisted emerging technique promise for PEF technology optimize within shorter time while minimizing solvent energy consumption. In this review, we provide comprehensive overview current state its implications recovering from waste. integration like play crucial role managing sustainably, reducing impact, harnessing full contained these objective critical review pretreatment conduct comparative analysis with other techniques.

Acid-hydrolyzed phenolic extract of parsley (Petroselinum crispum L.) leaves inhibits lipid oxidation in soybean oil-in-water emulsions

Food Research International, Journal Year: 2024, Volume and Issue: 187, P. 114452 - 114452

Published: May 3, 2024

The antioxidant activity of the natural phenolic extracts is limited in particular food systems due to existence compounds glycoside form. Acid hydrolysis post-treatment could be a tool convert glycosidic polyphenols aglycones. Therefore, this research investigated effects an acid on composition and parsley obtained by ultrasound-assisted extraction method delay lipid oxidation real system (i.e., soybean oil-in-water emulsion). conditions were varied maximize total content (TPC) 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. When exposed 0.6 M HCl for 2 h at 80 ℃, TPC was 716.92 ± 24.43 µmol gallic equivalent (GAE)/L, DPPH 66.89 1.63 %. Not only did increase concentrations individual polyphenols, but it also resulted release new phenolics such as myricetin acid. extract's metal chelating ferric-reducing increased significantly after hydrolysis. In emulsion containing 400 GAE/L, acid-hydrolyzed extract had 11-day lag phase headspace hexanal compared 6-day unhydrolyzed extract. findings indicated that conversion aglycones can help extend shelf-life emulsion-based foods.
