“…Otherwise, the separation steps are widely discussed in literature, such as precipitation (Rauch et al 1960;Min et al 2011;Kwak et al 2012;Nakano et al 2012), solvent extraction (Malmary et al 2000;Wasewar et al 2002;Matsumoto et al 2003;Yankov et al 2004;Alkaya et al 2009;Krzyzaniak et al 2013), membrane separation processes, and others. Membrane separation processes that have been studied include reverse osmosis, electrodialysis, and ultrafiltration (Kim and Moon 2001;Choi et al 2002;Madzingaidzo et al 2002;Li and Shahbazi 2006;González et al 2008;Ecker et al 2012;Lu et al 2012;Ramchandran et al 2012;Sikder et al 2012;Dey and Pal 2013;Pal and Dey 2013;Wang et al 2014).…”

Lactic acid is a naturally occurring organic acid that can be used in a wide variety of industries, such as the cosmetic, pharmaceutical, chemical, food, and, most recently, the medical industries. It can be made by the fermentation of sugars obtained from renewable resources, which means that it is an eco-friendly product that has attracted a lot of attention in recent years. In 2010, the U.S. Department of Energy issued a report that listed lactic acid as a potential building block for the future. Bearing the importance of lactic acid in mind, this review summarizes information about lactic acid properties and applications, as well as its production and purification processes.

“…NF has two remarkable features: one is the molecular weight cut-offs (MWCO) between reverse osmosis (RO) membranes and ultrafiltration (UF) membranes, which ranges from 200 to 2000 Da; the other is the separation of electrolytes due to the materials containing charged groups [15][16][17]. Solute separation in nanofiltration membrane involves mainly the electrostatic interaction of membrane and solutes on the membrane surface and size exclusion [18]. And the separation efficiency in a nanofiltration process gets influenced by parameters such as pH [19], concentration [20], applied transmembrane pressure [21], initial cross flow rate etc.…”

Response surface analysis methodology was used to optimize the concentrate process of phenolic acids from Lonicera japonica by nanofiltration technique. On the basis of the influences of pressure, temperature and circulating volume, the retention rate of neochlorogenic acid, chlorogenic acid and 4-dicaffeoylquinic acid were selected as index, molecular weight cut-off of nanofiltration membrane, concentration and pH were selected as influencing factors during concentrate process. The experiment mathematical model was arranged according to Box-Behnken central composite experiment design. The optimal concentrate conditions were as following: nanofiltration molecular weight cut-off, 150 Da; solutes concentration, 18.34 μg/mL; pH, 4.26. The predicted value of retention rate was 97.99% under the optimum conditions, and the experimental value was 98.03±0.24%, which was in accordance with the predicted value. These results demonstrate that the combination of Box-Behnken design and response surface analysis can well optimize the concentrate process of Lonicera japonica water-extraction by nanofiltration, and the results provide the basis for nanofiltration concentrate for heat-sensitive traditional Chinese medicine.

“…Increasingly, they are produced by environmental-friendly fermentation of glucose, starch, molasses [5,6,9,14,16,19]. The fermentation broth is neutral or weakly alkaline mixture of saccharides, organic and inorganic salts and fermentation microorganism [6,15]. First, the acid separation is done by broth ultrafiltration to remove microorganisms and some large proteins [6].…”

“…The fermentation broth is neutral or weakly alkaline mixture of saccharides, organic and inorganic salts and fermentation microorganism [6,15]. First, the acid separation is done by broth ultrafiltration to remove microorganisms and some large proteins [6]. The second step is converting, purifying and concentrating the organic acid solution [7,8], commonly using strong acid or ionic liquid [21] extraction.…”
