Vitamin B3 (nicotinic acid, NA) is selected as an example of a promising environmental eco-friendly metal sequestering reagent to functionalize the surface of nanoalumina-loaded sodium dodecyl sulfate (nano-Al 2 O 3 -SDS) sorbent. This reaction is accomplished via microwave-assisted heating using a solvent-free approach for the formation of a novel nano-Al 2 O 3 -SDS-NA sorbent. The functionalized nanomaterials are characterized by Fouriertransform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy. A comparative study is performed to explore and evaluate the sorption behaviors of nano-Al 2 O 3 , nano-Al 2 O 3 -SDS, and nano-Al 2 O 3 -SDS-NA sorbents for removal of Cu(II), Zn(II), and Pb(II) from aqueous solutions by the batch adsorption technique. The desired selectivity characteristics in the evaluated nanosorbents are confirmed from the determined maximum metal sorption capacity values of Cu(ΙΙ), Zn(II), and Pb(II) as 5700, 900, and 700 mmol g À1 by nano-Al 2 O 3 -SDS-NA sorbent, respectively, using a 5 mg dosage. The optimum contact pH, time, initial metal ion concentration and competing species are also investigated. The Langmuir, Brunauer-Emmet-Teller and Dubinin-Radushkevich adsorption isotherm models are applied to evaluate the interaction processes of Cu(II), Zn(II), and Pb(II) by nano-Al 2 O 3 , nano-Al 2 O 3 -SDS, and nano-Al 2 O 3 -SDS-NA sorbents. The potential applications of these nanosorbents for adsorptive removal of metal cations from real samples are successfully optimized via a micro-column technique.

“…The extraction was conducted according to a modified method described by Stafussa et al (). A proportion of 1:10 (m v −1 ) was used in which one gram of ground rice (brown rice, PC and PB) and 10 mL hydroethonolic solution (ethanol 40%) were kept under agitation in an incubator (Solab/SL222/Brazil) at 130 r.p.m.…”

“…According to Thammapat et al (), lipophilic antioxidants and phenolic compounds such as phenolic acids and flavonoids are abundant in brown rice and they constitute a potential benefit for human health since their antioxidant activity protects the cellular constituents, thus reducing their risk of developing disorders associated with oxidative stress (Stafussa et al , ). However, this potential benefit of the rice may be significantly affected by the processing methods used, including parboiling (Min et al , ; Paiva et al , ).…”

The conventional parboiling process decreases the total phenolic compounds (TPC) and the antioxidant activity (AA) of rice. In order to change this nutritional disadvantage, in this research we have proposed an unusual solution. Here, we added grape pomace (agro-industrial waste) in the process during the parboiling as a source of bioactive compounds (BC). An increase in the concentrations of TPC, flavonoids anthocyanins and antioxidant activity was found. Moreover, there was slightly change in the final colour of the rice (which tended towards red) in addition to added proline (NMR spectra), which is an amino acid that is characteristic of grapes. Therefore, we concluded that it is possible to improve the functionality of parboiled rice with the addition of grape pomace, besides promoting the valorisation and use of an agro-industrial waste rich in secondary metabolites.

“…This method is appropriate for increasing the extractability of polyphenols, covering usually nonextractable proanthocyanidins (Radenkovs et al, 2018). Meini et al (2019) demonstrated the positive effect of pectinase, cellulase and tannase on the release of phenolics from grape pomace matrix, while Stafussa et al (2016) investigated the possibility to inter-connect two food industry byproducts, using brewery's yeast biomass as biosorbent of the anthocyanins from grape pomace. Also, various fungi such as Trichoderma, Aspergillus, and Penicillium sp.…”

The growing demand for more sustainable, alternative processes leading to production of plant-derived preparations imposes the use of plants waste generated mainly by agri-food and pharmaceutical industries. These mostly unexploited but large quantities of plants waste also increase the interest in developing alternative approaches for sustainable production of therapeutic molecules. In order to reduce the amount of plant waste by further processing, different novel extraction techniques can be applied. Fruits and their industrial by-products are rich sources of different classes of compounds with therapeutic properties. The processed fruits waste can be reused and lead to novel pharmaceuticals, food supplements or functional foods. This review intends to briefly summarize recent aspects regarding the production of different active compounds from fruit by-products, and their therapeutic properties. The potential use of fruits by-products in different industries will be also discussed.
