“…Since CaCO 3 is the major component of the eggshell, its dissolution under acidic condition will break the strongly bounded structure and release the ESM [ 13 , 51 , 52 ]. Acid treatment with acetic acid, hydrochloric acid, or EDTA is commonly applied for the separation of the ESM [ 53 , 54 , 55 , 56 ]. Another strategy consists of loosening the bounds between the ESM and ES by immersing the ES in low acid solution followed by manual separation [ 54 , 55 , 57 , 58 ].…”

“…Another strategy consists of loosening the bounds between the ESM and ES by immersing the ES in low acid solution followed by manual separation [ 54 , 55 , 57 , 58 ]. During the acid treatment process, numerous parameters such as the incubation temperature, reaction time, moisture content, and type of acid used will influence the efficiency of this separation step [ 56 , 59 ].…”

The eggshell membrane (ESM), mainly composed of collagen-like proteins, is readily available as a waste product of the egg industry. As a novel biomaterial, ESM is attractive for its applications in the nutraceutical, cosmetic, and pharmaceutical fields. This review provides the main information about the structure and chemical composition of the ESM as well as some approaches for its isolation and solubilization. In addition, the review focuses on the role and performance of bioactive ESM-derived products in various applications, while a detailed literature survey is provided. The evaluation of the safety of ESM is also summarized. Finally, new perspectives regarding the potential of ESM as a novel biomaterial in various engineering fields are discussed. This review provides promising future directions for comprehensive application of ESM.

“…This protein removal mechanism is expected to be important near surfaces with loosely attached particles or with readily dissolvable surfaces. Higher frequency ultrasound tends to have higher energy absorption by liquid and thus greater acoustic streaming flow rates than lower frequencies at the same power intensity [45]. In addition, higher power intensities lead to greater acoustic streaming flow rates due to higher energy gradients in liquid between acoustically and nonacoustically stimulated areas.…”

“…Acoustic streaming causes bulk water movement toward and away from the membrane cake layer, with velocity gradients near the protein cake layer that may scour proteins from the surface. The effect of ultrasound on the flux and solute rejection in cross-flow UF of BSA-lysozyme binary protein mixture, using PES membrane (30 kDa MWCO), was investigated and reported [44,45]. The authors observed that ultrasonic wave not only enhanced the UF flux but also increased the lysozyme rejection.…”

Membrane fouling is one of the major issues encountered in membrane filtration including microfiltration, ultrafiltration, nanofiltration, and reverse osmosis. Membrane fouling can occur due to the reversible and irreversible deposition of particles, colloids, macromolecules, salts, and other types of elements. As a consequence, fouling causes a significant decrease in the permeate flux due to plugging of membrane pores, and adsorption of fouling material on the membrane's surface and/or in the pore walls. A lot of research efforts have been directed towards fouling remediation techniques or membrane cleaning alternatives. Although most of these methods are relatively functional, they have drawbacks and limitations. Among these methods, the use of ultrasound has been shown to be effective in enhancing mass transfer, cleaning, disinfection, and controlling fouling. In membrane filtration processes, ultrasound can help accelerating the permeate flux towards the membrane and decreasing the concentration of solutes accumulated in the membrane pores and on the membrane surfaces. Ultrasonic fouling control does not require chemical cleaning and can maintain a high permeate flux throughout the filtration process. In addition, wastewater contaminants can be degraded by ultrasound. Therefore, ultrasound creates unique physicochemical conditions, which can be used as an effective tool for membrane fouling control. In this chapter, ultrasound radiation as a unique method to modify physical and chemical properties of a complex fluid with applications in wastewater treatment and protein purification process is highlighted. At first, ultrasonic parameters and how their ability to enhance the delivery of fluid flow to the membrane surface and affect the physical and chemical properties of foulants are discussed. Furthermore, various ultrasonic methods, including continuous and intermittent waves, and its influences on membrane fouling, permeate flux, membrane cleaning and flux recovery are reviewed. The main role of wave streaming as a driving force for fluid acceleration and antifouling control, and the impact of ultrasound-generated bubble cavitation on preventing and removing fouling deposits are described. The challenges of current ultrasonic techniques, which need to be addressed so as to facilitate their widespread and successful implementation, are explored. This chapter examines how the periodic compression/ rarefaction cycles of ultrasound can influence mass transfer and membrane fouling. Also, the current knowledge and approaches to advance ultrasonic technology as an Advances in Membrane Technologies 2 effective method for membrane fouling remediation in wastewater treatment and protein purification downstream processing are presented in this chapter.

“…The RSM is always used in conjunction with the Box–Behnken design (BBD). Compared with the central composite design (CCD), the BBD avoids the axial points outside the experiment level and requires fewer runs . After that, a less laborious mathematical model is established for statistical analysis of experimental results.…”

The effect of ultrasound on the alkali extraction of proteins from eggshell membranes

Abstract: Ultrasound favours the detachment of big clumps of proteins from the eggshell membrane, facilitating the solubilisation of its compounds. The ultrasound had no effect on the protein properties tested in this study. © 2017 Society of Chemical Industry.
