摘要：
In this study, a nutritious, healthy Chongqing hotpot oil with excellent flavor was blended while considering nutrition, flavor, and health aspects. Four blended hotpot oils prepared from fragrant rapeseed, palm, sesame, and chicken oils were analyzed to determine their physicochemical properties, antioxidant capacities, levels of harmful substances, and nutritional compositions, and their sensory qualities were evaluated. Principal component analysis was performed to identify the best hotpot oil (10% chicken oil + 20% palm oil + 10% sesame oil + 60% fragrant rapeseed oil), which exhibited good antioxidant capacity (Oxidation Stability Index: 7.95 h; 2,2-diphenyl-1-picrylhydrazyl: 168.6 mu mol/kg, 2,2 '-azinobis-(3-ethylbenzothiazoline-6-sulfonate): 116.7 mu mol/kg, and ferric-reducing/antioxidant power: 63.9 mu mol/kg), a high sensory score (7.7/10), stable physicochemical properties (acid value: 0.27 mg/g and peroxide value: 0.01 g/100 g), and high tocopherol (54.22%), and phytosterol retention (98.52%) after boiling for 8 h. Although the 3,4-benzopyrene content of this hotpot oil exceeded the EU standard after boiling for 7 h, the increase in the amount of harmful substances was the lowest.
摘要：
This study compared the effect of five different adsorbents (activated clay, activated carbon, attapulgite clay, bentonite, diatomite) on the levels of nutrients, harmful substance retention, and decolorization in rice bran oil. Among the adsorbents tested, activated carbon displayed the highest decolorization efficiency (82.90%) and adsorption effect on 3,4-benzopyrene (BaP, 89.53%) and 3-monochloropropane-1,2-diol ester (41.55%), whereas activated clay had the highest oryzanol retention percentages (85.98%) and affordability. Activated carbon and activated clay were therefore selected as composite decolorizing agents. Based on single-factor and Box-Behnken response surface tests, the optimal conditions for decolorization efficiency (97.08%), oryzanol retention (89.62%), sterol retention (90.16%), vitamin E retention (79.91%), and benzo(a)pyrene adsorption percentages (95.98%) were determined to be achieved by using a 5% (w/w) composite decolorant (activated clay:activated carbon=5:1), at a temperature of 116celcius, with an incubation time of 33 min. This study provides evidence to support the efficacy of compound decolorants, which may have practical use in large-scale industrial applications of edible oil decolorization during refinement.

摘要：
The present study sought to evaluate the effects and mechanisms of mannitol and xylitol on the regeneration of spicy wheat gluten sticks (SWGSs) through texture profile analysis (TPA), Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), X-ray diffraction (XRD), and low-field nuclear magnetic resonance (LF-NMR). The rate constant of crystallization and the relative degree of crystallinity of SWGS substantially reduced with polyols addition after 4 weeks of storage at 4 degrees C. The peaks near 3385 cm-1 and 1081 cm-1 in FTIR of SWGS became wider with the addition of mannitol and xylitol, indicating that mannitol and xylitol formed hydrogen bonds by binding to wheat starch. The DSC experiment results showed that the addition of mannitol and xylitol could reduce the Tp and Delta H of SWGS powder effectively under different storage times. The NMR results showed that the water in SWGS was mainly immobile water, and the addition of mannitol and xylitol could increase the content of bound water and immobile water in SWGS and reduce the water migration. These results provided deeper insights into the action mechanism of mannitol and xylitol in delaying the quality change of starch products during storage, thereby providing a reference for inhibiting SWGS regeneration. Therefore, it could be inferred that improving the quality of SWGS by adding polyol might have significant application prospects in the food industry.
摘要：
Soy sauce, as a traditional seasoning, is widely favoured by Chinese and other Asian people for its unique colour, smell, and taste. In this study, a salt-tolerance Saccharomyces cerevisiae strain HF-130 was obtained via three rounds of ARTP (Atmospheric and Room Temperature Plasma) mutagenesis and high-salt based screening. The ethanol production of mutant HF-130 was increased by 98.8% in very high gravity fermentation. Furthermore, ATF1 gene was overexpressed in strain HF-130, generating ester-producing strain HF-130-ATF1. The ethyl acetate concentration of strain HF-130-ATF1 was increased by 130% compared to the strain HF-130. Finally, the soy sauce fermentation performance of Torulopsis globosa and HF-130-ATF1 was compared with T. globosa, HF-130, HF-130-ATF1, and Torulopsis and HF-130. Results showed ethyl acetate and isoamyl acetate concentrations in co-fermentation of T. globosa and HF-130-ATF1 were increased by 2.8-fold and 3.3-fold, respectively. In addition, the concentrations of ethyl propionate, ethyl caprylate, phenylethyl acetate, ethyl caprate, isobutyl acetate, isoamyl alcohol, phenylethyl alcohol, and phenylacetaldehyde were also improved. Notably, other three important flavour components, trimethylsilyl decyl ester, 2-methylbutanol, and octanoic acid were also detected in the co-fermentation of T. globosa and HF-130-ATF1, but not detected in the control strain T. globosa. This work is of great significance for improving the traditional soy sauce fermentation mode, and thus improving the flavour formation of soy sauce.

摘要：
Monascus red pigments (MRPs), natural food colorants from microorganisms, are widely used in the food industry but are not very stable during storage and processing. Therefore, this study aims to microencapsulate MRPs using an emulsification/internal gelation technique to improve the stability. The highest encapsulation efficiency (EE) of 70.32% +/- 0.28% was achieved when the percentage of NaCl in phosphate buffered saline (PBS) was 0.88%, the mass ratio of CaCO3 to NaAlg was 3.13, and the molar ratio of calcium to acid was 4.15. Spray-dried MRPs microcapsules had a smaller average diameter (D [4,3] approximate to 3 mu m) with a smooth surface and spherical shape. Moreover, the stability assays revealed that spray-dried MRPs microcapsules processed higher retention rate, especially under the treatments of heating, light and in vitro simulated gastrointestinal digestion. The spray-dried MRPs microcapsules exhibited the lowest degradation constant and longest half-life compared with free MRPs and freeze-dried MRPs microcapsules. These results demonstrated that combining emulsification/internal gelation with spray-drying is feasible for enhancing the stability of MRPs to broad its further application in the food industry.
摘要：
In the present work, a dual-modified waxy rice starch (OOWRS) fabricated with OSA and ozone was successfully used to stabilize the O/W Pickering emulsion. The molecular structure, surface properties, and underlying stabilizing mechanism were systematically investigated. The results showed that oxidation occurring on the surface of OSA-modified waxy rice starch (OSAWRS) resulted in the presence of indentations and cracks. The relative crystallinity of starch was generally decreased with increasing degree of oxidation. Due to the introduction of carbonyl and the variation in surface structure, the hydrophobicity and acidity of OSAWRS were significantly enhanced after the ozone treatment. Remarkably, OOWRS stabilized Pickering emulsion exhibited a feature of typical O/W emulsion, and the 0.5 h and 1 h OOWRS emulsion exhibited a more uniform droplet size as well as a higher surface potential. We also noted that a weak-gel network was formed within the OOWRS emulsion system as the hydrophilic starch chains played a bridging role. Two reasons for the improved stability of the emulsion were the special gel structure and the enhanced electrical repulsion among the droplets. This research provides that ozone-conjugated OSA modification is a promising strategy for improving the emulsion ability of starch-based Pickering emulsions.
摘要：
Using amino silica modified with fluorescein isothiocyanate (FITC), a quick fluorescence analysis technique is used for the detection of 3-monochloropropane-1,2-diol (3-MCPD). At 100 degrees C and pH 8.5, FITC-modified amino silica exhibits the lowest fluorescence intensity in the presence of 3-MCPD. This can predominantly be explained mostly explained by 3-MCPD's capacity to occupy the amino group that FITC normally binds to. The fluorescence intensity of FITC-modified amino silica was greatly quenched by 3-MCPD's reaction with the amino group under alkaline conditions, and the fluorescence intensity is different at different reaction times, reaction pH, and reaction temperature. The effects of various 3-MCPD concentrations on the optical characteristics of FITC-modified amino silica were also investigated. Fluorescence analysis is used to obtain a linear range from 0.025 to 1.0 mg/L for 3-MCPD detection under optimal experimental conditions, with a detection limit of 0.025 mg/L and a correlation coefficient of 0.9915. The quantity of 3-MCPD in soy sauce was measured under ideal conditions. Using the optimized conditions, the contents of 3-MCPD in soy sauce were determined. These results suggest that this method is sensitive to 3-MCPD and may have a substantial application in the rapid detection of food contaminants particularly, where the quality and safety of food products are of paramount concern.

摘要：
Constructing natural polymers such as cellulose, chitin, and chitosan into hydrogels with excellent stretchability and self-healing properties can greatly expand their applications but remains very challenging. Generally, the polysaccharide-based hydrogels have suffered from the trade-off between stiffness of the polysaccharide and stretchability due to the inherent nature. Thus, polysaccharide-based hydrogels (polysaccharides act as the matrix) with self-healing properties and excellent stretchability are scarcely reported. Here, a solvent-assisted strategy was developed to construct MXene-mediated cellulose conductive hydrogels with excellent stretchability (∼5300%) and self-healability. MXene (an emerging two-dimensional nanomaterial) was introduced as emerging noncovalent cross-linking sites between the solvated cellulose chains in a benzyltrimethylammonium hydroxide aqueous solution. The electrostatic interaction between the cellulose chains and terminal functional groups (O, OH, F) of MXene led to cross-linking of the cellulose chains by MXene to form a hydrogel. Due to the excellent properties of the cellulose-MXene conductive hydrogel, the work not only enabled their strong potential in both fields of electronic skins and energy storage but provided fresh ideas for some other stubborn polymers such as chitin to prepare hydrogels with excellent properties.

摘要：
A very low content of oleosome-associated proteins (OAPs) allows for long-term stability of oleosomes in mature seeds, but there is limited knowledge on these interfacial behaviors. Here, the effect of extraction solvents on the composition, structure, and interfacial properties of OAPs from Camellia oleifera were investigated. After lipid removal by cold acetone/ether (AE) and chloroform/methanol (CM), the OAPs-AE exhibited a white lumpy morphology, but the OAPs-CM was a transparent film. The major components of OAPs-AE and OAPs-CM were similar, including oleosin, Ole I, Ole II, Ole IV, and Ole V. The OAPs-CM had more alpha-helix (-60%) and beta-sheet (-15%) structures than that of OAPs-AE, while the OAPs-AE had a higher denaturation temperature (-90.9 degrees C). The residual phospholipid content in OAPs-AE was 21.5 times that of OAPs-CM. The OAPs-AE displayed an impressive ability to increase surface pressure at the air-water interface (-32 mN/m at 4000 s) and oil-water interface (-12 mN/m at 4000 s), even at a very low concentration (0.04 mg/mL). For the air-water interface, the diffusion rate of OAPs-AE was faster than that of OAPs-CM at all of the investigated pH values. These results provide a better understanding of OAPs as novel natural surface-active agents.
摘要：
Improving the dispersed stability of selenium nanoparticles (SeNPs) is the key to its application. In this study, yeast glucan with different degrees of amination (BNs) were used as stabilizers and capping agent to prepare dispersed SeNPs. The size, storage stability, and morphology of BNs/SeNPs were characterized. Results show that BNs/SeNPs presented positive potential and spherical morphologies with average particle size about 100-300nm and kept stable at room temperature for a long time. The CCK-8 assay showed that BNs/SeNPs had significantly lower toxicity to RAW264.7 cells than SeNPs. Moreover, BNs/SeNPs could inhibit the generation of NO, IL-1β and IL-6 effectively in RAW 264.7 macrophages induced by LPS, and down-regulate the mRNA transcription of iNOS, IL-1β, IL-6 and chemokines (CCL2 and CCL5), indicating that BNs/SeNPs had good anti-inflammatory activity. Therefore, aminated yeast glucan could improve the stability and bioactivity of SeNPs simultaneously, which is a promising stabilizer for SeNPs.
