Green Processes in Foodomics: Biorefineries in the Food Industry

Supercritical Carbon Dioxide Technology for Recovering Valuable Phytochemicals from Cannabis sativa L. and Valorization of Its Biomass for Food Applications

“…On the other hand, CO 2 comes into direct contact with the plant matrix during the extraction process, diffusing through plant tissues to extract compounds of interest. The key point that makes CO 2 an attractive solvent for food intents is the fact that it is a substance that is not chemically reactive [111]. Indeed, many studies reported the chemical stability of macronutrients after supercritical CO 2 processing such as sugars [99,102], dietary fibers [100], proteins [112,113], and others.…”

Exploiting waste derived from Musa spp. processing: Banana and plantain

“…Consequently, the initial design of the specific extraction processes should include a detailed evaluation of the type of solvent to be used, prioritizing those framed within green chemistry. 50,51 Evaluation of the impact of drying conditions on total phenolic compounds and antioxidant activity, as well as modeling of process variables using artificial neural networks. The samples, banana, were dried by warm air at 50 and 70°C and freeze-dried; each sample was subjected to multiple extractions: first with a methanol solution; three times with acetic acid (98:2), and then with an acetone-water solution (60:40), also three times.…”

“…In fact, in some cases they are considered hazardous wastes that must be carefully managed. Consequently, the initial design of the specific extraction processes should include a detailed evaluation of the type of solvent to be used, prioritizing those framed within green chemistry 50,51 …”

One-step ultrasound-assisted recovery of yellow-orange-red natural coloring from defatted annatto seeds: A cleaner processing alternative

“…Recent works reviewed the newest developments concerning green and efficient extraction technologies to obtain carotenoids [9] , [10] . The use of green solvents such as edible oils, supercritical CO 2 , ionic liquids, deep eutectic solvent, and natural deep eutectic solvents combined with emerging technologies including supercritical fluid extraction (SFE) [11] , [12] , pressurized liquid extraction (PLE) [13] , high-intensity ultrasound (HIUS) [14] , [15] , pulsed electric field (PEF) [16] , and enzyme-assisted extraction (EAE) [17] have great potential to efficiently recover carotenoids, although further studies involving the analysis of the colorant quality, process cost, and environmental impact are still necessary. Among the technologies, HIUS stands out as a promising treatment to recover phytochemicals in short processing times with high extraction yields [18] , [19] .…”
