Ovomucin, accounting for ∼3.5% of total egg white protein, is responsible for the thick gel characteristics of liquid egg white. Besides its excellent foaming and emulsion capacities, it possesses anti-viral, anti-bacterial, anti-tumor and other bioactivities. This paper reviews compositional, structural, physicochemical, functional and biological properties of ovomucin, as well as development of methods of extraction. As one of the least defined proteins in egg white, further study is required to characterize the structure and to explore its full potential in new applications as functional foods and nutraceuticals.

Amyloid fibril formation of α-synuclein (αSN) is a hallmark of synucleinopathies. Although the previous studies have provided numerous insights into the molecular basis of αSN amyloid formation, it remains unclear how αSN self-assembles into amyloid fibrils in vivo. Here, we show that αSN amyloid formation is accelerated in the presence of two macromolecular crowders, polyethylene glycol (PEG) (MW: ~10,000) and dextran (DEX) (MW: ~500,000), with a maximum at approximately 7% (w/v) PEG and 7% (w/v) DEX.

Food allergens are defined by their stability during digestion, with allergenicity largely influenced by resistance to enzymatic hydrolysis. Ovalbumin (OVA), a major egg protein, is a significant contributor to food allergies, particularly in children. Our previous work demonstrated that high hydrostatic pressure (HHP) treatment reduces OVA allergenicity by disrupting conformational epitopes and altering its structure.

Bioactive peptides rich in branched-chain amino acids (BCAAs) are an effective way to alleviate fatigue conditions, but the deep mechanism remains unclear. This study investigated the anti-fatigue effect of branched-chain amino acid-enriched egg white peptides (BEWPs) through the gut-muscle axis by gut bacteria and untargeted metabolomic analyses. The results demonstrated that BEWPs enhanced exercise endurance and strength by also promoting gastrocnemius development in mice.

Edible films are significant in prolonging the shelf life of meat products. Herein, we prepared some edible coatings (EW/TNPCSs) based on egg white/chitosan/pectin as polymer matrix, containing tannic acid-nisin composite nano-crosslinker with antibacterial-antioxidant activities. The results of preservation indicated that the prepared EW/TNPCSs reduced the water loss of chilled pork and delayed the changes of taste, texture and surface color.

Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high-performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for optimal bone development has been little addressed so far.
