“…Ion exchange resins have been applied in many industries, such as food processing (Alexandratos, ; Geng et al, ). Resins have been used in food processing to remove limonin bitterness from orange juice and oleic acid from ethanolic solutions (Kola, Kaya, Duran, & Altan, ), to deacidify crude low‐cocoa butter and red palm oil (Wu et al, ), and to deacidify lipid feedstocks from food oil and other solutions (Cren & Meirelles, ; Cuevas et al, ). Few studies have reported applying ion exchange resins to deacidify fruit juice or wine.…”

In this study, an effective deacidification process for kiwifruit wine using ion exchange resins was investigated. Static adsorption experiments were conducted to screen an appropriate resin and optimize the volume ratio of resin to wine. Dynamic adsorption experiments were conducted to optimize the flow rate. Sensory and chemical analysis of the deacidified kiwifruit wine were also performed. The results demonstrated that 330 resin with a maximum adsorption capacity decreased total acid and citric acid to 4.32 and 1.39 g/L in kiwifruit wine. The acid adsorption process fitted Ho's sorption kinetic model well. The volume ratio of the 330 resin to wine and the feed flow rate were further optimized to be 1:30 and 4 mL/min. Kiwifruit wine with total acid and citric acid contents of 7.98 and 4.74 g/L was obtained, under optimum conditions, while preserving alcohol, vitamin C (Vc), flavonoids and phenol content, and improving the flavor. Practical applicationsThe high acidity in kiwifruit wine depress the sensory quality and attraction to consumers.Resins are applied for liquid treatment because of high efficiency, insolubility and low cost. This work showed that 330 resin treatment is a promising method to deacidify kiwifruit wine and provided an economical and effective processing method for kiwifruit processing enterprises.Monitoring acidity change and kiwifruit wine quality help enterprises better control the process. Furthermore, the easy removal of resins will greatly reduce energy consumption, resulting in lower processing cost.

Generally, conventional copolymers sorbent available commercially such as D202 anion exchange resin and Amberlite IRA 420 are normally based on styrenedivinylbenzene (DVB) copolymer which these resins show hydrophobic characteristic.…”

Strong anion exchange hypercrosslinked of poly(HEMA-co-EGDMA-co-VBC) (PHEV) and strong anion exchange hypercrosslinked of poly(styrene-co-EGDMA-co-VBC) (PSEV) were prepared via amination reaction with dimethylbutyl amine (DMBA) as the amination agent in dried toluene. The resins were characterized by SEM, FTIR, BET and elemental analysis. SEM results showed that there was no significant change of the particles shape after amination reaction for both strong anion exchange hypercrosslinked PHEV and strong anion exchange hypercrosslinked PSEV. Specific surface area (SSA) of strong anion exchange hypercrosslinked PHEV increase from 1035 m 2 /g to 1090 m 2 /g when amination reaction take place. However, SSA of strong anion exchange hypercrosslinked PHEV decreased from 124 m 2 /g to 27 m 2 /g. From FTIR spectra, significant drop occurred at 1265 cm -1 band after amination reaction of strong anion exchange hypercrosslinked PSEV but SSA of strong anion exchange hypercrosslinkedPHEV showed slightly significant drop. Elemental analysis showed that nitrogen content of strong anion exchange hypercrosslinked PHEV significantly increase from 0.10% to 1.46% resulted to high IEC value. Meanwhile, nitrogen content in strong anion exchange hypercrosslinked PSEV only showed small increment in nitrogen content from 0.36% to 0.63% led to low IEC value.

“…However, there are a few studies investigating the adsorption of FFA on adsorbents such as different types of clay: montmorillonite, sepiolite, kaolinite cristobalite and bentonite [23][24][25][26][27][28]. Recently, there are some studies on the adsorption of free fatty acids using anion resins [29][30][31]. The present work reports the use of a different anion-exchange resin (Dowex 550A) for adsorbing FFA from different oils as previous step to transesterification reaction in order to replace the esterification reaction.…”

Biodiesel is an alternative source of energy in diesel engines in its neat form or as a blend with conventional diesel fuel. The raw feedstock costs represent a lot of the overall biodiesel production cost. Therefore, the employment of waste oils or non-edible oils (which do not compete with edible oils) as feedstock for biodiesel production are presented as the best alternative. However, the presence of free fatty acids (FFA) in these oils is undesirable for biodiesel production due to the transesterification reaction performance is reduced. Hence, in this paper, the adsorption as treatment for reducing or removing FFA from oils prior to transesterification reaction for biodiesel production is examined using a strong anion-exchange resin in order to avoid esterification reaction employed commonly prior to transesterification reaction.
