“…This can inhibit the oxidation of wine constituents, including phenolics, certain metals, tyrosine, and aldehydes, during the winemaking process, while retaining the sensory and nutritional value of wine. Furthermore, as previously reported, adding COS-based materials can reduce the concentrations of metals, such as boron, lead, mercury, and antimony, and that of ochratoxin A in process water [24][25][26][27], which can markedly improve wine quality. Therefore, in this study, COS was applied as an alternative to SO 2 in winemaking, and the antimicrobial activity of COS during winemaking was investigated using our own separated contaminated organisms and known wine spoilage organisms in comparison with the action of SO 2 .…”

Sulfur dioxide (SO2) has been used for centuries as a preservative in winemaking. However, the addition of SO2 is associated with allergic reactions and can negatively affect wine quality. In our work, chitooligosaccharide (COS) was applied as an alternative to SO2 in winemaking, and its antimicrobial activity during winemaking was investigated in comparison with the action of SO2. The optimal concentration of COS was identified as 500 mg/L. The antimicrobial effect of COS was evaluated using known and our own separated wine spoilage organisms. The antimicrobial effect of 500 mg/L COS was found to be comparable with that of 100 mg/L SO2. Furthermore, using 500 mg/L COS as an additive during winemaking did notinfluence the cell growth of Saccharomyces cerevisiae. Therefore, COS can be used as an additive in winemaking.

“…When environmental-friendly, biodegradable and renewable biomass-based flocculants were applied (Demey et al, 2014;Elwakeel et al, 2012), the flocculation process further enjoys an advantage of low risk of secondary contamination (Chatterjee et al, 2009;Liu et al, 2014;Roussy et al, 2005;Wang et al, 2013;Yang et al, 2014a). Nonetheless, studies on removal of combined pollutants of antibiotics and heavy metals using flocculation method is quite sparse to date, as there are three flocculation difficulties.…”

“…At present, many separation techniques have already been reported to separate boron from brine, such as adsorption [5], chemical precipitation [6], reverse osmosis [7], solvent extraction [8,9], and so on. Wherein, solvent extraction is one of the nonenergy intensive mass transfer processes and is widely used to separate and recycle valuable elements from complex matrix for its high selectivity and recovery.…”

In order to economical and environmental-friendly recycle of boron from underground brine, the extraction of boron was carried out in this work by the continuous centrifugal technique using 2-ethyl-1,3-hexanediol (EHD) + sulfonated kerosene (SK) extraction system, and the extraction mechanism was also investigated by the combination of FT-IR with slope method. The results showed that boron can be effectively extracted from underground water with the concentration of boron 5.43 g·L−1 by five-stage centrifugal extraction using 30% EHD + 70% SK at pH = 2.0–3.0, R(O/A) = 1 : 2, and the extraction rate reached 98.46%. Boron in the organic phase can be well five-stage back-extracted by 1.0 mol·L−1·NaOH at R(O/A) = 1 : 1 with a back-extraction rate of 97.00%. About 88.32% boron in the aqueous phase obtained by back-extraction can be recycled in H3BO3 form by evaporation crystallization after acidified to pH < 2.5. The extraction mechanism indicated that the extraction is completed mainly based on the esterification reaction between alcoholic hydroxyl in EHD and -OH in B(OH)3 at the stoichiometric ratio 1 : 1 to generate a stable six-membered ring structure of boric acid ester.
