“…As previously reported, in order to control and reduce membrane fouling, pre-treatments are usually used prior the clarification process, with the aim to decrease the content of macromolecules that are able to accumulate in the membrane surface or in the membrane pores. The pre-treatments include mainly the application of pectolic enzymes, fining agents, chitosan or centrifugation [32,84]. A decrease of both total and fouling resistance with the increasing of feed flowrate was also observed by Vladisavljević et al [62] in the clarification of depectinized apple juice with ceramic UF membranes.…”

“…However, the main drawback of polymeric membranes is their low stability in drastic conditions of pH and consequently, limited shelf-life for juice processing applications. On the other hand, ceramic membranes have greater resistance to chemical degradation, low tendency of fouling, good cleanability and much longer shelf life making them suitable for many applications for which polymeric membranes cannot be used; their disadvantage is the high cost if compared with polymeric membranes [32].…”

The fruit juice industry is one of the food sectors that has invested the most in the implementation of new technologies, such as non-thermal technologies. Among them, membrane processes are considered today well-established separation techniques to support the production and marketing of innovative fruit juices designed to exploit the sensory characteristics and nutritional peculiarities of fresh fruits. Pressure-driven membrane operations, membrane distillation, osmotic distillation and pervaporation have been widely investigated in the last few decades to replace conventional technologies used in fruit juice processing industry (i.e., clarification, stabilization, concentration and recovery of aroma compounds). This paper will review the significant progresses on the use of membrane-based operations in fruit juice processing industry in the light of the growing interest towards products with improved safety, quality and nutritional value and sustainable processes characterized by low energy consumption and low environmental impact.

“…They have some advantages compared to conventional methods: The separation can be carried out at a low temperature in order to reduce the operational costs and to avoid injuring heat‐sensitive components. Additionally, additives are not required for the process and to the possibility of creating several hybrid technologies exists (Bhattacharjee, Saxena, & Dutta, ; Domingues, Ramos, Cardoso, & Reis, ; Echavarría, Torras, Pagán, & Ibarz, ; Urosevic, Povrenović, Vukosavljević, Urošević, & Stevanović, ). These processes have been widely used for the concentration of the bioactive compounds present in fruit and vegetable juices and extracts (Almanasrah et al, ; Chaparro, Castillo, Vaillant, Servent, & Dornier, ; Polidori et al, ).…”

Lycopene is a carotenoid found in tomatoes and other red fruits and vegetables. It is known for its antioxidant properties, which is associated with the prevention of cancer. Raw tomatoes and tomato‐based products are important sources of dietary lycopene. This study aimed to evaluate the integration of diafiltration and reverse osmosis processes to concentrate tomato pulp and to obtain a lycopene‐rich extract with a high antioxidant capacity and a low molecular weight. Diafiltration was efficient in desalting the tomato pulp, maintaining the lycopene concentration of the tomato at the same level as the whole tomato pulp. The permeate flux of the diafiltrated tomato pulp was 29.5 L·h−1·m−2 and the concentration factor of lycopene was 2.4. Additionally, it was found that the antioxidant capacity increased at the same rate than the lycopene content. Practical applications Lycopene is a carotenoid found in tomatoes with higher antioxidant capacity. The membrane separation processes are considered as an alternative to the thermal processes, providing the concentration of these bioactive compounds present in the tomato using soft process temperatures, besides preserving the sensory and aroma characteristics. The integration of the processes with microfiltration and diafiltration membranes allows the production of a final product from the tomato with high concentration of lycopene, promoting the assistance in the prevention of various diseases related to human health, and a reduced soluble solids content of reduced molecular weight.

“…Such separation processes have been commonly applied in the purification of essential oils such as clove oil, patchouli oil, ginger oil, phenolic compound, and other essential oils [3][4][5]. The introduction of membrane separation for bioproduct extraction was massively studied [6][7]. However, recent separation technologies such as polymeric based membranes were rarely applied in the purification of essential oils.…”

The application of membranes for clove oil purification has the potential to improve the efficiency and effectiveness of processing. The main problem that occurs is the polymer-based membranes tend to change in properties such as weakening, dissolving, and swelling when contact with clove oil. In this study, cellulose acetate membrane was developed with TiO2 nano-particles to reduce swelling effect and coating with polyvinyl alcohol (PVA) to modify membrane surface. The membranes were prepared using dry-wet phase inversion method from dope solution with polymer concentration of 14–20 wt% and nano-particles of TiO2 with a concentration of 0–1.5 wt% in total solid. The formed membrane was coated with PVA with a concentration of 2–5 wt% crosslinked using glutaraldehyde. The SEM results show that prepared membrane are asymmetric membranes and show the coated layer of PVA on the surface. The FTIR spectra confirm that the PVA is successfully crosslinked and the addition of nano-particles TiO2 decreases the membrane swelling degree, significantly. In the addition of 0.5 wt% of nano-TiO2 can increase the flux from 0.54 to 0.66 L × m−2 × h−1 × bar−1. The coated membrane surface using PVA increases the selectivity of the membrane to produce clove oil permeates with eugenol content of 82.5 % from 68 %.
