Fragrant bioethanol: A valued bioproduct from orange juice and essential oil extraction
Abstract We identify the composition of a less known, yet important bioproduct obtained in relatively high amount during orange fruit processing for juice and essential oil extraction comprised of bioethanol dissolving valued terpenes. Green cosmetic, perfume and biosolvent applications are anticipated.
Integral Extraction of Opuntia ficus-indica Peel Bioproducts via Microwave-Assisted Hydrodiffusion and Hydrodistillation
The microwave-assisted hydrodiffusion extraction process affords high quality pectin and betanin from the peel of red and green Opuntia ficus-indica fruits under mild conditions. An aqueous mixture of valued bioproducts is readily obtained from the fruit peel cell water itself, without any water addition. The integral extract can be used as such to formulate nutraceutical beverages and products or, upon straightforward separation, to isolate pectin and betanin devoid of chemical contaminants suitable as ingredients for products ranging from food and beverage to cosmetic and pharmaceutical sectors. Betanin shows exceptional stability thanks to the high amounts of antioxidant polyphenols in t…
Economic and Technical Feasibility of Betanin and Pectin Extraction from Opuntia ficus-indica Peel via Microwave-Assisted Hydrodiffusion
Investigating the feasibility of betanin and pectin extraction from Opuntia ficus-indica peel via microwave-assisted hydrodiffusion and gravity, this study identifies selected important economic and technical aspects associated with this innovative production route starting from prickly pear fruit discards. Which benefits would be derived from this process? Would production be limited to Opuntia-growing countries or, likewise to what happens with dried lemon peel chiefly imported from Argentina, would production take place abroad also? Can distributed manufacturing based on clean extraction technology compete with centralized production using conventional chemical processes?
Sicilian Opuntia ficus‐indica Seed Oil: Fatty Acid Composition and Bio‐Economical Aspects
The fatty acid composition of the seed oil from the yellow fruit of Opuntia ficus-indica widely grown in Sicily shows several distinctive features. The oil obtained comprises significant amounts of vaccenic acid along with several other unsaturated fatty acids showing several health benefits, including linolenic, trans-13-octadecenoic, gondoic, 7Z,10Z-hexadecadienoic, and gadoleic acid. The economic analysis shows the significant advantage of carrying out the extraction from fruits considered unfit for consumption. Practical applications: The fatty acid composition of Sicilian Opuntia ficus-indica seed oil is similar to that of fruits grown in Tunisia, while it has a completely different pr…
