“…It can be expected that steady state permeate flux increases with the TMP increase, as it is the driving force in MF process [61] and enhanced driving force for solvent flux was bigger than the membrane fouling resistance [62].…”

This paper reports the study of the cross-flow microfiltration (MF) of glycerol fermentation broths with Citrobacter freundii bacteria. A single channel tubular ceramic membrane with a nominal pore size of 0.14 µm was used. It has been demonstrated that the MF ceramic membrane has been successfully applied to bacteria cell removal and to effectively eliminate colloidal particles from glycerol fermentation broths. However, due to fouling, the significant reduction of the MF performance has been demonstrated. In order to investigate the impact of transmembrane pressure (TMP) and feed flow rate (Q) on MF performance, 24 experiments have been performed. The highest steady state permeate flux (138.97 dm3/m2h) was achieved for 0.12 MPa and 1000 dm3/h. Fouling analysis has been studied based on the resistance-in series model. It has been found that the percentage of irreversible fouling resistance during the MF increases with increasing TMP and Q. The permeate flux regeneration has been achieved by membrane cleaning with 3 wt % NaOH and 3 wt % H3PO4 at 45 °C. The results of this study are expected to be useful in industrially employing the MF process as the first step of glycerol fermentation broth purification.

“…Catechin and quercetin were the prominent flavonoids in the evaluation of the leaves of the five species studied in this work, and these compounds were identified by Balyan and Sarkar [ 73 ] and Balyan et al [ 74 ] in jambolan leaves and by Faleiro et al [ 41 ], Saber et al [ 42 ], Santos et al [ 50 ], and Beltrame et al [ 44 ] when studying araçá leaves. Anthocyanins, flavones and flavonones were also identified in leaves of the same plant in the study of Zandoná et al [ 43 ].…”

This integrative review aims to identify the main flavonoids present in some species of the Myrtaceae family. Studies published between 2016 and 2022 were selected, specifically those which were fully available and written in Portuguese, English, or Spanish, and which were related to the fruits araçá (Psidium cattleianum), cambuí (Myrciaria floribunda), gabiroba (Campomanesia xanthocarpa), jabuticaba (Plinia cauliflora), and jambolan (Syzygium cumini). Scientific studies were gathered and selected in Google Scholar, Scielo, and Science Direct indexed databases, out of which 14 were about araçá, 7 concerned cambuí, 4 were about gabiroba, 29 were related to jabuticaba, and 33 concerned jambolan, when we observed the pre-established inclusion criteria. Results showed that the anthocyanins, such as cyanidin, petunidin, malvidin, and delphinidin, were the mostly identified class of flavonoids in plants of the Myrtaceae family, mainly relating to the purple/reddish color of the evaluated fruits. Other compounds, such as catechin, epicatechin, quercetin, and rutin were also identified in different constituent fractions, such as leaves, peel, pulp, seeds, and in developed products, such as jams, desserts, wines, teas, and other beverages. It is also worth noting the positive health effects verified in these studies, such as anti-inflammatory qualities for jambolan, antidiabetic qualities for gabiroba, antioxidant qualities for araçá, and cardioprotective actions for jabuticaba, which are related to the presence of these phytochemicals. Therefore, it is possible to point out that flavonoids are important compounds in the chemical constitution of the studied plants of the Myrtaceae family, with promising potential in the development of new products by the food, chemical, and pharmaceutical industries due to their bioactive properties.

“…The flux decline during membrane filtrations of different beverages is frequently described by the model proposed by Field et al (1995). (Balyan & Sarkar, 2018;Córdova et al, 2020;Jain et al, 2018;. Jain et al (2018) applied the model proposed by Field et al (1995) to identify fouling occurrences during microfiltration of bitter gourd (Momordica charantia) extract through asymmetric polymeric hollow fiber membranes.…”

This work evaluates a filtration process with and without centrifugation through asymmetric spinel hollow membranes for clarification of hibiscus extract. The centrifugation step increased the steady state flux through the membrane in 23.4%. Complete pore blockage was the main fouling mechanism and polysaccharides, proteins and phenolic compounds were mostly responsible for fouling. After sequential membrane filtration, total soluble solids, total solids and L* color coordinate (luminosity) were reduced from 5.53 to 4.03 °Brix, 47,120 to 37,780 mg/L, and 15.69 to 22.03, respectively. Seven individual bioactive compounds were identified in both extract and permeate by ultra performance liquid chromatography-mass spectrometer. The filtrated extract showed greater stability than the feed extract after 20 storage days (reduction of 43.1% in tea cream formation). The sequential centrifugation and filtration through asymmetric spinel hollow membranes can be potentially applied to produce hibiscus ready-to-drink tea with high antioxidant content. Practical applications Membrane separation process is a filtration technique based on the permeation of solute molecules through a semipermeable membrane. The ceramic membrane is widely used for the purification and clarification of food products, but the cost of material is a disadvantage for the use of filtration processes. This work demonstrated the possibility of exploring the use of asymmetric spinel hollow membrane in clarification and increased stability of teas ready for consumption. This membrane presents composition of 25 wt% of dolomite and 75 wt% of alumina, thus presenting high stability, high permeate flows and low-cost ceramic material. This filtration technology membrane can also be combined as a pre-treatment, such as centrifugation, thus improving filtration efficiency and product stability. Finally, the new membrane used was feasible to produce a hibiscus tea ready-to-drink rich in antioxidants. How to cite this article: Paraíso CM, dos Santos SS, Pereira Bessa L, et al.
