“…Moreover, a large volume of solvent causes more absorption of microwave energy and thus sufficient microwave energy may not be available for cell breakage, which is considered important for effective leaching out of the target analyte. Similar effects were also recorded during the MAE of tea polyphenols and tea caffeine (Pare et al ., ; Pan et al ., ). Taking all these factors into consideration, a loading range of 10:1 to 30:1 mL/g was selected for the optimisation study.…”

Recovery of Biomolecules from Food Wastes — A Review

2014

View full text Add to dashboard Cite

Food wastes are produced by a variety of sources, ranging from agricultural operations to household consumption. About 38% occurs during food processing. At present, the European Union legislation encourages the exploitation of co-products. This valorisation can be achieved through the extraction of high-value components such as proteins, polysaccharides, fibres, flavour compounds, and phytochemicals, which can be re-used as nutritionally and pharmacologically functional ingredients. Extraction can proceed according to solid-liquid extraction, Soxhlet extraction, pressurized fluid extraction, supercritical fluid extraction, ultrasound-assisted extraction, microwave-assisted extraction, pulsed electric field extraction, and enzyme-assisted extraction. Nevertheless, these techniques cannot be used indiscriminately and their choice depends on the type of biomolecules and matrix, the scale processing (laboratory or industrial), the ratio between production costs and economic values of the compounds to be extracted. The vegetable wastes include trimmings, peelings, stems, seeds, shells, bran, residues remaining after extraction of oil, starch, sugar, and juice. The animal-derived wastes include wastes from bred animals, wastes from seafood, wastes from dairy processing. The recovered biomolecules and by-products can be used to produce functional foods or as adjuvants in food processing or in medicinal and pharmaceutical preparations. This work is an overview of the type and amounts of food wastes; food waste legislation; conventional and novel techniques suitable for extracting biomolecules; food, medicinal and pharmaceutical uses of the recovered biomolecules and by-products, and future trends in these areas.

“…As a continuation of our work in further developing technologies for novel microwave-assisted processes (MAP TM ) [1][2][3][4][5][6][7][8][9][10][11][12][13], we have undertaken a research program aimed at assessing the feasibility of using microwaves as a processing tool in the industrial sector. More specifically, we have an interest in assessing and validating applications for the petrochemical and petroleum sectors with the aim to reduce energy intensity as well as greenhouse gas emissions.…”

A novel microwave reactor has been constructed for the conversion of ethane to ethylene. The bench-top, pilot-scale facility is capable of conventional furnace heating and microwave-assisted heating, thus allowing direct comparative studies between the conventional industry-wide process and the novel microwaveassisted conversion process. The latter makes use of chemical substances called susceptors that are good microwave absorbers and can transfer heat energy to the surrounding environment. The ethane feed stream is thus heated to achieve thermal conversion to ethylene. Data validating the apparatus and preliminary data on the feasibility of conversion are presented.
