Sugars are critical components of fruit juice. The binding of sugars and aroma compounds may affect the release of flavor in juices. In this study, the effects of sucrose, glucose, and fructose on the release of active aroma compounds in fresh and high hydrostatic pressure-processed (HPP) Tainong mango juice were evaluated. Using gas chromatography-mass spectrometry/olfactometry and odor activity values, four volatiles were identified as active aroma compounds in fresh and HPP mango juice. Furthermore, Fourier transform infrared spectroscopy and isothermal titration calorimetry illustrated that the sugar-volatile interaction was hydrophobically-driven, with hydrogen bonding to some extent. As the concentrations of sugar were increased in the fresh juice, a significant change in the release of active volatiles occurred, while HPP juice showed stronger retention of the active volatiles. The results suggest that high hydrostatic pressure processing maintained the freshness of mango juice flavor by strengthening aroma retention within the juice matrix.While dairy proteins have traditionally been used to stabilize nanoemulsions, there is a trend towards plant-based formulations. Additionally, both types of protein are poorly soluble near their isoelectric point. The main goals of this research were to develop and characterize Maillard conjugates from pea protein (PPI) or caseinate and dextran, and to evaluate the physical stability of nanoemulsions made with such emulsifiers at various ionic strengths, pH = 4.6, and temperatures during storage, as well as lutein color retention over storage. Protein conjugates formed nanoemulsions with diameters of 125 ± 12 nm (PDI = 0.13 ± 0.00) and 269 ± 36 nm (PDI = 0.76 ± 0.42) (pH = 7) for caseinate and PPI, respectively. Conjugation improved the physical stability (droplet size) of emulsions at the isoelectric point, during storage at 4-55 °C, and in ionic solutions. Lutein color degradation was better associated with particle size than conjugation and was lowest for PPI-stabilized emulsions. This study suggests that Maillard conjugation could improve PPI emulsification properties.Direct determination of arsenic species in real samples is challenging due to their trace concentration and spectral interferences by coexisting ions. Herein, we proposed an ultrasound-assisted dispersive solid phase microextraction (DSPME) procedure for the analyses of the trace inorganic arsenic. The hydrothermally synthesized cadmium sulfide nanoparticles (CdS NPs) completely adsorbed both arsenic species within 20 s at the initial arsenic concentration of 100 µg L-1. The detection limit (3 S/m) of the proposed method was found to be 0.5 ± 0.2 and 0.8 ± 0.2 ng L-1 for As(III) and As(V), respectively. The accuracy of the method against the systematic and constant errors was confirmed by the analysis of the Standard Reference Material (SRM) (>95% recovery with less then 5% RSD). The Student's t-test values were found to be less than the critical Student's t value at a 95% confidence level. The method was successfully employed for the determination of arsenic in food samples.Soybean is one of the greatest crops in the world, with about 348.7 million tons being produced in 2018. Soybean hull is a by-product produced during the processing of soybean to obtain flour and oil. Though not being actually exploited, it is a source of polyphenols with antioxidant activity. Here, the extraction of polyphenols from soybean hull was performed by means of an alkaline hydrolysis treatment, which was optimized by the response surface methodology. At the optimal region, a total phenolic content of 0.72 g gallic acid equivalents per 100 g of soybean hull was obtained with an antioxidant activity of 2.17 mmoles of Trolox equivalents. Polyphenols responsible for the antioxidant activities were identified by LC-MS, including phenolic acids, anthocyanins, stilbenes, and the two main isoflavones of soybean, daidzein and genistein, in their non-glycosylated form. Other alternative extraction methods based on Aspergillus oryzae fermentation and α-amylase hydrolysis are also proposed.Tenebrio molitor larvae protein isolates (TPIs) were extracted using the alkaline extraction and acid precipitation methods (AEAP) assisted by NaCl (salting-in) and (NH4)2SO4 (salting-out) procedures. The structural, physicochemical, and functional properties of TPIs were investigated. It was found that the salt-assisted treatments did not affect the total amino acid content but altered specific amino acid compositions. The salting-in-AEAP extraction resulted in non-significant (P > 0.05) differences in zeta potential, hydrophobicity, thermal stability, solubility and foaming capacity compared with the AEAP extraction. Salting-out-AEAP extraction significantly (P less then 0.05) increased overall protein solubility, emulsion activity, foaming capacity and stability that were associated with lower hydrophobicity, higher zeta potential, α-helix and disulfide bond contents. The salting-in-AEAP-out extraction generated the greatest protein yield (39.54%), emulsion activity index (55.5 m2/g), foaming capacity (205%) as well as foaming stability (65.59%).Antarctic krill oil (KO) was encapsulated into yeast cells (YCs), and the physicochemical, morphological, and conformational characterizations of KO-loaded YCs (KYCs) were investigated. Moreover, the oxidation stability and in vitro release behavior of KYCs were evaluated. Rilematovir manufacturer Results showed that KYCs provided significantly higher oxidative stability than native KO. The fatty acid profile remained obviously unchanged after encapsulation. Most interestingly, the phospholipid proportion increased from 49.76% ± 1.42% to 59.92% ± 1.39% after encapsulation. Furthermore, there was a slow and prolonged release of KYCs, along with higher bioaccessibility of docosahexaenoic acid and eicosapentaenoic acid than the KO-in-water emulsion (69.62% ± 7.67% and 66.67% ± 4.55% vs 47.44% ± 4.4% and 39.74% ± 3.89%). KO encapsulation in YCs can be considered as an efficient approach for extending the oxidative and in vitro stability of this nutritious oil and facilitating its application in food products.
