“…In water treatment technology, membrane separation received significant advancement in this recent years and mainly subjected to its ability to remove microbes, particles and even reducing water with high heavy metal [16]. Beside, membrane filtration has also been applied in the field of food processing [17][18][19][20][21], downstream process especially for biotechnology industry [22][23][24][25], seawater treatment or desalination process [24,[26][27][28][29][30] and many other type of separations [17,[31][32][33][34]. The main reason of choosing membrane as part of the process were usually ease of operation, minimum waste generation and relatively low power needs [35].…”

Enhancing membrane permeation is usually an important parameter in the membrane development for filtration. In this study, polysulfone membrane equipped with different concentration of silver nitrate (0.5-2.0 wt%) were fabricated by phase inversion and later be known as composite membrane (CM) followed by letter (A till F) to indicate membrane composition. This study will investigate the effect of silver nitrate concentration to membrane permeation. Membrane morphology was investigated via scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Based on SEM examination, all composite membrane exhibits sponge-like structure otherwise FTIR for composite membrane with silver nitrate (CM B till CM E) shows additional peak at 1149.57 and 1294.24 indicating silver nitrate presence. In permeability test, composite membrane (CM C) with 1.0wt% silver nitrate achieved 22.25 L/m 2 .h of flux, the highest among all the composite membrane configuration. Thus, the result implied the addition of silver nitrate can increase permeation performance though excessive content may reduce the performance up to 50% of flux reduction. This work provides a better understanding of silver nitrate implication toward membrane permeability therefore provide an insight to any application of silver nitrate in membrane composition.

“…To date, the main application of these membrane‐based technologies has been widely focused on extracting compounds from food products (e.g., fruits and juices), waste from food industries, and the treatment of agro‐food by‐products . Membranes are actually considered competitive for large‐scale treatment . In addition, they have been used in the processing of natural extracts to obtain concentrates enriched in several compounds, such as organic acids (e.g., ascorbic, citric, glutamic, folic, and malic acids), vitamins (e.g., Vitamin C), pigments (e.g., betaxanthines and betacyanines), and sugars (e.g., glucose, fructose, and sucrose) …”

“…On the other hand, most of the compounds permeated in the three processes (MF, UF, or NF) are phenolic compounds, which have been widely recognized by their antioxidant properties . Recently, Cassano et al and Castro‐Muñoz et al reported compilations in which several studies focus on the recovery of phenolic compounds from natural sources (e.g., apple, orange, pomegranate, pineapple, and grape) and agro‐food byproducts (e.g., wastewater from nixtamalization, mill wastewater, and liquor pressing) using membrane‐based technologies. These authors argue that phenolic compounds may have a promising potential application as food additives.…”

The production of specific metabolites using microorganism has been promoted and enhanced by two different approaches, such as modification of the metabolic pathways of microorganism and optimization of culture medium conditions to synthesize specific compounds. However, research community is today focused on the development of processes and techniques for a suitable recovery of metabolites from different stages of fermentation. For this purpose, the use of organic solvents has been the most common approach for the recovery of specific target compounds according to the solvent affinity. Additionally, these techniques also require the implementation of unit processes to obtain better recovery rates; it means that solvent extraction methods need the implementation of additional steps to recover the solvents used, which may involve the increase of final costs in the production process. For this reason, researchers have started to consider membrane-based technologies (e.g. microfiltration [MF], ultrafiltration [UF], and nanofiltration [NF]), as an alternative for the recovery of metabolites from fermentation broths. Therefore, the objective of this paper is to provide an overview of the current findings of the recovery of metabolites from fermentation broths by means of pressuredriven membrane processes. Particular attention will be paid to relevant data, analyzing and discussing according to the membrane features, metabolite properties, and some other phenomena that influence in the separation.Moreover, a framework of the application of the MF, UF, and NF processes in solutes recovery is addressed. Finally, some fundamentals of these processes are also given.

“…This observation confirms the deposition of polyphenols present in bitter gourd extract, on the membrane surface. The attachment of polyphenols to the membrane surface was through hydrogen bonding between the O─H of polyphenols and the S═O group present in the sulfone group of the membrane (Cassano, Luca, Conidi, & Drioli, ).…”

Bitter gourd extract was clarified by cross flow ultrafiltration using a hollow fiber module under total recycle mode using polysulfone based membrane. The 70 kDa membrane was found to be the most suitable among the 10-, 44-, 70-, and 120 kDa molecular weight cut-off membranes. Variations of various resistances, viz. membrane hydraulic resistance, pore blocking resistance, and fouling layer resistance with operating conditions were examined. Effect of transmembrane pressure and cross flow rate on flux and quality parameters were examined and based on these results 138 kPa transmembrane pressure and 30 L/hr cross flow rate were found suitable operating conditions for processing of extract. Storage study revealed that the ultrafiltered extract could be successfully stored for 20 weeks without any additive, preservative and flavoring agent, maintaining its natural taste, aroma, nutrition, flavor, color, smell, and other nutritional qualities at par to fresh extract. Practical applicationsAqueous extract of vegetables possesses many ingredients having therapeutic values and medicinal importance. Bitter gourd is one such vegetable containing many health benefits. The present work deals with development of a cold sterilization process for bitter gourd extract using hollow fiber ultrafiltration without any additives, preservatives, and subsequent in-depth storage analysis. Novelty of the process includes identification of suitable membrane for this purpose, detailed flux decline analysis of the selected membrane, effects of operating conditions on the throughput and physicochemical parameters of the processed extract. The storage study indicates that the extract can be preserved for 20 weeks without any external chemicals maintaining the natural flavor, taste, and nutrient profiles of the original extract. Filtration experiments were conducted in scalable hollow fiber units. Therefore, this study is of paramount significance in scaling up of processing of bitter gourd extract having long shelf life.
