Quantification of Allergic Crustacean Tropomyosin Using Shared Signature Peptides in Processed Foods with a Mass Spectrometry-Based Proteomic Strategy

“…This may be because the digestion time is too long, leading to nonspecific cleavage of peptides . For an ideal digestion process, the signature peptides not only need to remain stable but also need to determine their digestion degree, to accurately represent of target proteins in the extract. − To determine the digestion efficiency, the synthetic quantitative peptide IVELEEELR was used, and a fitted equation of y = 0.2439 x + 0.0656 ( R 2 = 0.9999) was obtained. A sample blank matrix solution was obtained by subjecting a blank sample without crustacean allergens to the sample preparation steps.…”

Aminopoly(carboxylic acid)-Functionalized PolyHIPE Beads toward Eliminating Trace Heavy Metal Ions from Water

“…PolyHIPEs are highly interconnected macroporous polymers with void sizes and interconnected pore sizes typically in the range of 5–100 and 0.5–20 μm, respectively. − PolyHIPEs are fabricated by polymerizing the continuous phase (or the monomers in it) of a HIPE and subsequently removing its dispersed phase. − Compared with a commercial helix static mixer, polyHIPE is a more efficient micromixer due to its interconnected three-dimensional (3D) porous structure. In polyHIPEs, fluids can be effectively mixed in a laminar flow regime. , Owing to the excellent mixing effect, polyHIPE is expected to act as a highly efficient water-treatment-based material, when it is appropriately surface functionalized. − …”

Mechanism of Interconnected Pore Formation in High Internal Phase Emulsion-Templated Polymer

“…However, when a small amount of surfactant, such as 1.0 wt %, was added to the Pickering HIPE, it was found that the surfactant not only disaggregated the particles to leave them well-dispersed in the continuous phase but also tended to occupy the oil−water interface at the contact point of adjacent droplets. 33,39 The interconnected pore structure formed in the resulting polymer foams.…”

“…High internal phase emulsion (HIPE), an emulsion containing internal phase of >74% dispersed as individual droplets, has been known for many years and has found applications in fields such as food, fuels, oil recovery, biphasic interfacial catalysis, and cosmetics. − In the past 20 years, a growing interest focuses on its application in materials science, i.e., as template to fabricate highly porous structure (so-called HIPE-templating technique). ,− HIPE is commonly stabilized by high content of nonionic surfactant (5–50%, relative to its continuous phase) owing to its high volume ratio of disperse phase/continuous phase. − When the HIPE contains monomers in its continuous phase, polymerization of the monomers and removal of the dispersed phase could cause a highly open-cell foam, named polyHIPE. − The HIPE-templating technique provides the advantages of generating porous materials with a diverse morphology, for example, polymer foams, membranes, beads, or rods. Since the structure of polyHIPE replicates from its precursor HIPE-template, by tuning the droplet size and the chemical nature of HIPE phases, polyHIPEs with designed performance can be fabricated. − Moreover, in situ or postpolymerization approaches can be also adapted to tune the surface area or endow polyHIPE with additional chemical properties. − PolyHIPEs could be used in a wide range of areas, including energy storage applications, , tissue engineering, chromatography, separation, , microreactors, , sound absorption, , and catalysis. − The implementation of these applications largely depends on their highly open-cellular structure, i.e., the presence of interconnected pores (also named pore throats or windows) between adjacent voids.…”

“…The suggestion is also verified by the previous work in which the w/o (water-in-St/DVB) HIPE was stabilized by only copolymer particles or copolymer. , The resulting polymer foams have a closed-cell porous structure owing to the lack of surfactant. However, when a small amount of surfactant, such as 1.0 wt %, was added to the Pickering HIPE, it was found that the surfactant not only disaggregated the particles to leave them well-dispersed in the continuous phase but also tended to occupy the oil–water interface at the contact point of adjacent droplets. , The interconnected pore structure formed in the resulting polymer foams.…”
