Detailed rheological analyses and fine structural characterizations were conducted to elucidate the mechanisms underpinning gel formation. The results indicate that amylose content and amylopectin chain length distribution are pivotal factors; specifically, an amylose content exceeding 5% is essential for gel formation was proposed for the first time. Modified starches exhibited a higher proportion of both short (DP 6–8) and long chains (DP > 26) compared to their native counterparts. Rheological assessments demonstrated that these gels maintained thermal stability through repeated heating and cooling cycles between 90 °C and 4 °C. Notably, <em>Tt</em>4αGT treatment significantly enhanced gel strength, particularly in tapioca starch (TS), and improved the thickening performance and reversibility of starch. The gel network structure was primarily stabilized by hydrogen bonds, supplemented by electrostatic interactions.

This involves using various thickened foodstuffs, which must be evaluated using unified, rheological, colloidal, and tribological techniques/standards. During swallowing, food bolus undergoes rapid, nonlinear, large deformations across a wide range of timescales. However, the ideal rheological profile for safe swallowing is still not known, and the study of foods under large deformation is inadequate. This work aimed to employ large-amplitude oscillatory shear (LAOS) analysis to describe the behavior of thicker foods under different timescales. Mayonnaise, a representative with complex rheological behaviors, is considered a suitable model for studying dysphagia-oriented foods. The study used multiple LAOS analysis models, including algebraic stress bifurcation to determine yield points, the Kamani–Donley–Rogers recovery rheology model to identify recoverable and unrecoverable components, and a data-driven constitutive model for precise LAOS behavior prediction. Other methods used included Fourier transform rheology, Lissajous curve, stress decomposition, strain-stiffening and shear-thickening ratios, dissipation ratio, and the sequence of physical processes. Importantly, it was observed that as the testing frequency increased, the apparent nonlinearity trajectories of mayonnaise collapsed inward with slight rotations. The timescale of deformation can strongly or weakly influence the intensity and type of non-Newtonian flows observed depending on the LAOS behaviors at different frequencies. This study enhanced the development and evaluation of dysphagia-oriented products at different timescales from a rheological perspective, which may bring new insight into the on-demand management of dysphagia and motivate innovative ideas in diet design and processing.</div></div>","PeriodicalId":320,"journal":{"name":"Food Hydrocolloids","volume":"161 ","pages":"Article 110867"},"PeriodicalIF":11.0,"publicationDate":"2024-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142748372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current review aims to examine the present state and prospects of using the LbL assembly technique for the concurrent delivery of both probiotics and bioactive compounds into the gastrointestinal system. In LbL assemblies, unigenric and polygenric wall material could be used to encapsulate a single or an aggregate of cells through direct or indirect encapsulation. It is established that during LbL assembly synthesis for encapsulation, polyelectrolytes with large molecular weights are used for layering, giving the opportunity to use these layers to carry bioactive compounds while keeping probiotics in the core. Several technologies, including extrusion, coacervation, emulsification, spray and freeze drying, and others, could be solely used or in combination to produce LbL assemblies of desired properties. The LbL assemblies can significantly reduce environmental damage to encapsulated cells and bioactive compounds and preserve their metabolic activity and function. Moreover, a wide array of compounds, such as prebiotics, omega-3 fatty acids, phytosterols, curcuminoids, carotenoids, anthocyanins, vitamins, and several other bioactive compounds of interest, could be supplemented in the layers of LbL assemblies, which are delivered to a precise location by systematic disintegration of layers in the gastrointestinal system.
