Although the color of lutein is vibrant, its stability during thermal processing remains a significant challenge that has yet to be overcome. A comprehensive understanding of the interactions between pea protein isolate (PPI) and lutein, as well as their influence on lutein retention and the solution behavior of PPI itself, is crucial for the development of pea protein-based products with optimized color. Currently, PPI provided a pronounced protective effect against the thermal degradation of lutein, primarily by influencing the retention rate, overall color variation, and total antioxidant capacity of lutein. Fluorescence spectroscopy revealed static quenching with strong affinity between PPI and lutein. The surface hydrophobicity of PPI after binding lutein decreased significantly (<i>p</i> &lt; 0.05), while the secondary structure of PPI remained stable without notable relaxation or unfolding. Notably, lutein exists in both dispersed and aggregated forms, while the resulting lutein–PPI complex manifested as stable spherical nanoparticles. Polydispersity index and Z-average diameter measurements reveal that the lutein–PPI complex is more homogeneous and stable than PPI alone. In summary, compared to previous references, the present study fundamentally enhanced understanding of the underlying mechanisms involved in the interaction of PPI with lutein, thereby providing valuable insights for the development of novel plant-derived protein products with improved color stability.</p></div>","PeriodicalId":564,"journal":{"name":"Food Biophysics","volume":"20 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142679770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This widespread deficiency is quite alarming, as it can lead to significant health risks and increase susceptibility to various diseases, thereby compromising overall well-being. Vitamin D in its native form has a limited shelf life (approximately a year at ambient temperature), low stability, and poor bioavailability; however, encapsulation can improve these characteristics without compromising its biological effectiveness and controlled release. The encapsulation technique and wall material type used have a significant role in the process. The present article provides a comprehensive overview of the prevailing advanced encapsulation techniques, such as emulsification, coacervation, nanoliposomes, solid lipid particles, solvent evaporation, electrospinning, spray drying and lyophilization, along with various wall materials used, to improve the shelf life, stability, and bioavailability of vitamin D.

The increased global demand for gelatin and issues regarding mammalian collagen have prompted an imperative urge for alternative sources. Therefore, this study aimed to explore the impact of ultrasound-assisted extraction on the physicochemical, functional, and bioactive attributes of gelatin obtained from <i>Tenualosa ilisha</i> scales. Ultrasound-assisted gelatin (UAG) extraction substantially increased the yield (34.49%), reducing fat and moisture content compared to water bath gelatin (WBG) extraction (20.06%). Sodium dodecyl-sulfate polyacrylamide gel electrophoresis (SDS-PAGE) revealed α1, α2, and β chains, corroborating a triple helical conformation with UAG displaying shorter peptide composition. Fourier-transform infrared spectroscopy (FT-IR) showcased distinct peaks for amide- I, II, III, and A with decreased molecular order owing to ultrasound treatment. The WBG exhibited a lower UV-transmittance and a higher gel melting temperature, whereby, UAG displayed an excellent foaming capacity and stability with improved performance at higher concentrations. The WBG demonstrated superior emulsion activity and stability index, however, the emulsion activity of both gelatins declined with increasing concentrations. The gelatins showed a similar water-holding capacity, although WBG possessed a greater fat-binding capacity compared to UAG. However, UAG demonstrated enhanced antioxidant effects, revealing an IC₅₀ of 121.17 ± 2.38 for scavenging free radicals and an EC₅₀ of 184.48 ± 3.16 for reducing Fe³⁺, thus, minimizing oxidative stress.

All five mathematical models, namely, Newton, Logarithmic, Page, Henderson and Pabis, Midilli and Kucuk, and the ANN model, exhibit a high degree of accuracy in their fit. The ANN model surpasses all empirical models in predicting drying behaviour across all drying temperatures, with the highest correlation coefficient of 0.9987 and the lowest root mean square error value of 0.01364. Moisture diffusivity and the convective mass transfer coefficient were found ranged from 4.46 × 10^–9 to 10.2 × 10^–9 m²/s and 8.9 × 10^–7 to 25.3 × 10^–7 m/s, respectively, at drying temperatures of 50 to 80 °C.
