The analysis results of FTIR, ζ-potential, surface hydrophobicity and free sulfhydryl group content indicated that hydrogen bonding, electrostatic interactions, hydrophobic interactions, and disulfide bonds drove the assembly of protein fibrils. Specifically, acid-heat treatment for 24 h was able to form a large number of high-aspect-ratio semi-flexible fibrils. After heating for 32 h, fibrils formed fibrillar cluster aggregates. With increasing pH, electrostatic interactions governed the structural and morphological evolution. When the pH was increased from 2.0 to 5.0, amorphous aggregation was triggered. At pH 7.0 (SPIF-pH7), electrostatic repulsion partially dissociated the fibrils into short fibrils. This structure enhanced the migration and adsorption efficiency of the protein interface (adsorption capacity, 27.96 %), which was conducive to the formation of a relatively thick viscoelastic film. The foam was evenly distributed, with low coalescence and disproportionation, promoting foam formation and stability. This discovery broke through the traditional understanding that an acidic environment (pH 2.0) was necessary to achieve excellent foaming properties. The application of angel cake showed that 12.5 % SPIF-pH7 instead of egg white could increase the specific volume from 2.37 mL/g to 2.64 mL/g, and the springiness (1.16) was close to that of the control group (1.28).

Results revealed that lauric acid was successfully grafted onto both needle-like LCNC-I and elliptical LCNC-Ⅱ without destroying their crystal structures. Compared to LCNC-Ⅱ, LCNC-I exhibited superior hydrophobicity and emulsifying properties due to its needle-like morphology and higher crystallinity, zeta potential, substitution degree, and contact angle, resulting in higher encapsulation efficiency of PFEO microcapsules prepared with LCNC-I as the emulsifiers. The highest encapsulation efficiencies (92.87 % for Gel/LCNC-I/PFEO and 87.12 % for Gel/LCNC-II/PFEO) were achieved with 13 wt% gelatin and a 1:5 mass ratio of core material (PFEO) to wall material (gelatin and LCNCs). Compared to Gel/LCNC-Ⅱ/PFEO, Gel/LCNC-I/PFEO microcapsules exhibited a more uniform particle size, superior redispersion stability, and a longer dissolution time, attributed to the excellent emulsifying properties of LCNC-I and its strong interaction with gelatin.

MRI results correlated well with peptide and polysaccharide release kinetics in the digestion fluid. UTE 3D imaging showed stable bread volume during gastric digestion, followed by volume loss, surface roughening, and fluid ingress into pores during intestinal digestion, consistently with gluten hydrolysis. T₂ analysis distinguished more mobile water in the pores and less mobiles ones in bread. An increase in the amount of more mobile protons suggested erosion-driven exposure and internal enzymatic attack. The release of starch hydrolysis products was shown to be independent on the breakdown of the gluten network and could be monitored with T₂ in the digestion fluid.

The incorporation of these chelators was observed to reconfigure the puff's microstructure. This process increased the puff porosity from 68 % to over 84 % and created larger pores with a mean diameter exceeding 100 μm. This engineered architecture accelerated hydration kinetics and weakened the hardness of the matrix. Consequently, the chelators induced structural collapse of puffs within 30 s. Moreover, this approach engineered a disintegration pathway dominated by controlled swelling and softening. This also led to the formation of a cohesive, low-adhesion bolus for swallowing safety, which contrasted sharply with the high-adhesion paste from conventional starch-based commercial puffs. Multivariate analysis identified the porosity and contact angle as critical factors for quick disintegration. Notably, the natural chelator (CPP) exhibited oral disintegration comparable to synthetic chelators, highlighting its potential as a clean-label alternative.
