Food Chem 2024; 446:138863. [PMID: 38428084 DOI: 10.1016/j.foodchem.2024.138863] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Revised: 02/21/2024] [Accepted: 02/25/2024] [Indexed: 03/03/2024]
Abstract
Brewer's spent grain (BSG) is an abundant agro-industrial residue and a sustainable low-cost source for extracting proteins. The composition and functionality of BSG protein concentrates are affected by extraction conditions. This study examined the use of citric acid (CA) and HCl to precipitate BSG proteins. The resultant protein concentrates were compared in terms of their composition and functional properties. The BSG protein concentrate precipitated by CA had 10% lower protein content, 5.8% higher carbohydrate, and 5.4% higher lipid content than the sample precipitated by HCl. Hydrophilic/hydrophobic protein and saturated/unsaturated fatty acid ratios increased by 16.9% and 26.5% respectively, in the sample precipitated by CA. The formation of CA-cross-linkages was verified using shotgun proteomics and Fourier transform infrared spectroscopy. Precipitation by CA adversely affected protein solubility and emulsifying properties, while improving foaming properties. This study provides insights into the role of precipitants in modulating the properties of protein concentrates.

Abstract
Curcumin is a natural lipophilic polyphenol that exhibits significant various biological properties such as antioxidant and anti-inflammatory properties following oral administration. However, its uses have shown limitations concerning aqueous solubility, bioavailability and biodegradability that could be improved by prolamin-based nanoparticle. In this study, curcumin was encapsulated into prolamin from sorghum (SOP) and wheat (WHP) and distilled spirit spent grain (DSSGP), which was obtained after microbial proteolysis of the former two cereal grains. All the three prolamins showed clear variation of protein profiles and microstructure as confirmed by electrophoresis analysis, disulfide bond determination and Fourier-transform infrared spectroscopy (FTIR). For curcumin-loaded nanospheres (NPs) fabrication, three prolamin-based NPs shared features of spherical shape, uniform particle size, and smooth surface. The average size ranged from 122 to 193 nm depending on the prolamin variety and curcumin loading. In the experiments in vitro, curcumin showed significantly improved UV/thermal stability. Furthermore, DSSGP was more resistant to enzymatic digestion in vitro, hence achieving the controlled release of curcumin in gastrointestinal tract. Collectively, the results indicated the improved bioavailability and biodegradability of curcumin encapsulated by DSSGP, which would be an innovative potential encapsulant for effective protection and targeted delivery of hydrophobic compounds.

Abstract
Traditionally, diverse natural bioactive compounds (polyphenols, proteins, fatty acids, dietary fibers) are used as inhibitors of starch digestive enzymes for lowering glycemic index (GI) and preventing type 2 diabetes mellitus (T2DM). In recent years, organic nanomaterials (ONMs) have drawn a great attention because of their ability to overcome the stability and solubility issues of bioactive. This review aimed to elucidate the implications of ONMs in lowering GI and as encapsulating agents of enzymes inhibitors. The major ONMs are presented. The mechanisms underlying the inhibition of enzymes, the stability within the gastrointestinal tract (GIT) and safety of ONMs are also provided. As a result of encapsulation of bioactive in ONMs, a more pronounced inhibition of enzymes was observed compared to un-encapsulated bioactive. More importantly, the lower the size of ONMs, the higher their inhibitory effects due to facile binding with enzymes. Additionally, in vivo studies exhibited the potentiality of ONMs for protection and sustained release of insulin for GI management. Overall, regulating the GI using ONMs could be a safe, robust and viable alternative compared to synthetic drugs (acarbose and voglibose) and un-encapsulated bioactive. Future researches should prioritize ONMs in real food products and evaluate their safety on a case-by-case basis.

Colloids Surf B Biointerfaces 2023; 222:113080.

Abstract
In this study, a novel method was developed to encapsulate hydrophobic compounds by self-assembly of cod protein (CP) triggered by breaking disulfide bonds. Curcumin (Cur), a representative lipid-soluble polyphenol, was selected as a model to evaluate the potential of CP nanoparticles as novel and accessible nanocarriers. Results showed that the protein structure gradually unfolded with increasing dithiothreitol (DTT) concentration, indicating that S-S cleavage was conducive to forming a looser structure. The resultant unfolded CP exposed more hydrophobic sites, facilitating its interaction with hydrophobic compounds. The encapsulation efficiency (EE) of formed CP-Cur nanoparticles was relatively high, reaching 99.09%, 98.8%, and 89.77% when the mass ratios of CP to Cur were 20:1, 10:1, and 5:1 (w/v), respectively. The hydrophobic interaction, weak van der Waals, and hydrogen bond were the forces contributing to the formation of CP-Cur nanoparticles, whereas the hydrophobic interaction played a crucial role. The CP-Cur complex exhibited increased stability and a homogeneous-stable structural phase. Thus, this research not only proposed a novel and simple encapsulation method of hydrophobic bioactive compounds but also provided a theoretical reference for the application of reductants in food or pharmacy system.

Abstract
In this study, glycated soy β-conglycinin (β-CG) stabilized curcumin (Cur) composites were fabricated by a unique reversible self-assembly character of β-conglycinin-dextran conjugates (β-CG-DEX). Intrinsic fluorescence and far-UV CD spectra revealed that glycation did not affect the self-assembly property of β-CG in the pH-shifting treatment. The structure of β-CG-DEX could be unfolded at pH 12.0 and reassembled during acidification (from pH 12.0 to 7.0). Meanwhile, β-CG-DEX-3d, which was incubated at 60 °C for 3 days, exhibited a high loading capacity (123.4 mg/g) for curcumin, which far exceeds that (74.90 mg/g) of β-CG-Cur. Moreover, the reassembled β-CG-DEX-3d-Cur showed eminent antioxidant activity of approximately 1.5 times higher than that of free curcumin. During the simulated gastrointestinal condition, compared with β-CG-Cur, β-CG-DEX-3d-Cur nanoparticles showed a more stable and sustained release of curcumin. Thus, β-CG-DEX has immense potential to become a new delivery carrier for hydrophobic food components by means of a self-assembly strategy.

Abstract
In comparison to conventional encapsulation methods of phenolic compounds (PCs), pH-driven method is green, simple and requires low energy consumption. It has a huge potential for industrial applications, and can overcome more effectively the aqueous solubility, stability and bioavailability issues related to PCs by changing pH to induce the encapsulation of PCs. This review aims to shed light on the use of pH-driven method for encapsulating PCs. The preparation steps and principles governing pH-driven method using various carriers and delivery systems are provided. A comparison of pH-driven with other methods is also presented. To circumvent the drawbacks of pH-driven method, improvement strategies are proposed. The essence of pH-driven method relies simultaneously on alkalization and acidification to bind PCs and carriers. It is used for the development of nanoemulsions, liposomes, edible films, nanoparticles, nanogels and functional foods. As a result of pH-driven method, PCs-loaded carriers may have smaller size, high encapsulation efficiency, more sustained-release and good bioavailability, due mainly to effects of pH change on the structure and properties of PCs as well as carriers. Finally, modification of wall materials and type of acidifier are considered as efficient approaches to improve the pH-driven method.
