Meanwhile, the COM had a higher ⊎-carotene retention ratio owing to its strong steric hindrance for the release of ⊎-carotene.…”

BACKGROUND Great efforts have been made to improve the oral bioaccessibility of lipophilic ingredients with multi‐functionalities. Achieving intestinal delivery of lipophilic ingredients and their encapsulation in micelles composed of bile salts and lipid hydrolysates (i.e. fatty acids) is critical for improving oral bioaccessibility. Therefore, oil‐core microcapsules are considered ideal carriers of lipophilic ingredients. Previous studies have reported oil‐core/zein‐shell microcapsules constructed by a one‐step anti‐solvent process. Still, its efficacy as an intestinal delivery system was limited because if the porous shell structure. RESULTS Zein solution was pretreated with ultrasound and tannic acid (TA) cross‐linking. Composite oil‐core microcapsule (COM) with a compact shell structure was successfully prepared by using modified zein solution in the anti‐solvent process. Fourier‐transform infrared spectroscopy and circular dichroism analyses indicated that ultrasound and TA synergistically promote the conformational transition of zein from α‐helix to β‐sheet and enhance the hydrophobic interactions among protein chains. The above changes contribute to the strengthen of shell zein network. Correspondingly, COM presents superior encapsulation efficiency and environmental stability over the simple oil‐core microcapsule (SOM) prepared without the use of ultrasound and TA. Furthermore, antioxidant activity of β‐carotene was well retained during the encapsulation process. In vitro studies indicated that COM was more resistant to digestibility and acid‐induced swelling. More than 87% of β‐carotene could be released in the intestine in a sustainable way. The controllable release behavior thus promoted a significant increase in bioaccessibility of β‐carotene encapsulated in COM compared to SOM (85.9% versus 48.5%). CONCLUSION The COM generated here shows potential for bioaccessibility improvement of lipophilic ingredients. © 2022 Society of Chemical Industry.

“…12–15 Fessi et al 16 constructed a 1-methylnaphthalene (1-MN)/water Pickering emulsion using bare TiO 2 nanoparticles without any surfactant as the photocatalyst and stabilizer, which intensified the photocatalytic degradation of 1-MN compared with the non-emulsified system containing TiO 2 nanoparticles. Cao et al 17 prepared an edible Pickering emulsion stabilized with zein and N -(2-hydroxy)propyl-3-trimethylammonium chitosan chloride (HTCC), which exhibited good stability against high-concentration salt ions and could be used as potential carrier for the transport of lipophilic nutrients.…”

“…However, they are thermodynamically unstable systems (McClements & Jafari, 2018). Pickering emulsions are stabilised by particles (Shah et al ., 2016; Cao et al ., 2021). The particles with a balance of hydrophilic and hydrophobic surface properties irreversibly adsorb to the interface between oil and water (Rodrigues Costa et al ., 2020; Ribeiro et al ., 2022), making the resulting Pickering emulsions more stable for a long time (Xu et al ., 2020).…”

Summary Chitosan (CS) derivatives, chemically modified appropriately, can be used to produce nanoparticles with good properties. In this work, using CS, hydroxypropyl CS (HPCS) and HPCS modified by cinnamic acid (HPCS‐CA) derivative as raw materials, the nanoparticles were synthesised by ion crosslinking method with tripolyphosphate. FT‐IR spectra indicated that CS and its derivatives successfully cross‐linked with TPP at the molecular level. XRD and TG results exhibited changes in crystallinity and thermal stability. The nanoparticles had narrow size distribution and were nearly spherical. The surfaces of the nanoparticles were all positively charged. The nanoparticles‐stabilised oil‐in‐water Pickering emulsions were obtained by high‐speed homogenisation. The emulsions' morphology was reported by confocal laser scanning microscopy, indicating that the Pickering emulsions were synthesised successfully. The stability of the emulsion stabilised by HPCS‐CA nanoparticles was better than that of CS and HPCS nanoparticles. Taking curcumin as the target component, its stability in Pickering emulsions was good. The Pickering emulsion stabilised by HPCS‐CA nanoparticles may be a novel bioactive compound delivery system.
