Ligustrum robustum (Rxob.) Blume was utilized as an natural additive to protect oil quality during the high temperature processing. L. robustum exhibited the remarkable capability to inhibit peroxide value, acid value, viscosity and color deterioration of oil. Meanwhile, L. robustum inhibited the decomposition of unsaturated fatty acids and the formation of trans fatty acids to protect the nutritional value of the oil. In addition, L. robustum increased the initial oxidation temperature of oil and raised its initial decomposition temperature. With high content of total phenols (126.9 g gallic acid equivalent /kg extract) and flavonoids (135.6 g rutin equivalent /kg extract), L. robustum showed the remarkable antioxidant and reducing capacities and was effective in scavenging free radicals and inhibiting lipid peroxidation. Furthermore, Ligurobustoside B was identified as the phenolic component in L. robustum sample with the high amount. All present results suggest that L. robustum has potential to be utilized as the natural additive for protecting oil quality during the high temperature processing. Chemical compounds studied in this article Ligurobustoside B (PubChem CID: 102,316,894).

The low solubility of phenolic compounds in oils limits their protective effect on oil quality. In the present study, novel microemulsions were designed and prepared with Ligustrum robustum (Rxob.) Blume polyphenols extract (LRE) using soybean oil as the oil phase, a combination of Tween80 and Span80 as surfactants, and ethanol as the co-surfactant, and subsequently characterized and evaluated their properties and performance in oil. Results showed that the amount of LRE dissolved in prepared microemulsions could reach 0.025 g/g oil. According to the droplet size, rheology, differential scanning calorimetry, and transmission electron microscopy measurements, LRE had no negative effects on microemulsion structure and increased the particle size, viscosity, and interfacial strength of microemulsion. Moreover, LRE exhibited remarkable antioxidant activities, and the LRE-loaded microemulsions showed no obvious cytotoxicity on Caco-2 cells. Furthermore, the LRE-loaded microemulsions exhibited superior effectiveness in inhibiting oil oxidation during storage, compared to the direct addition of LRE. All results suggest that the microemulsion has the potential used as an embedded material for natural antioxidants in food industry.

The increasing concerns about health have led to a growing demand for high-quality fried foods. The potential uses of Ligustrum robustum (Rxob.) Blume, a traditional tea in China, as natural additives to enhance the quality of starchy food during frying was studied. Results indicated that L. robustum polyphenols extract (LREs) could improve the quality of fried starchy food, according to the tests of color, moisture content, oil content, texture property, and volatile flavor. The in vitro digestion results demonstrated that LRE reduced the final glucose content from 11.35 ± 0.17 to 10.80 ± 0.70 mmol/L and increased the phenolic content of fried starch foods from 1.23 ± 0.04 to 3.76 ± 0.14 mg/g. The appearance and polarizing microscopy results showed that LRE promoted large starch bulges on the surface of fried starchy foods. Meanwhile, X-ray diffraction results showed that LRE increased the intensity of characteristic diffraction peak of fried starch with a range of 21.8%–28%, and Fourier transform infrared results showed that LRE reduced the damage to short-range order structure of starch caused by the frying process. In addition, LRE increased the aggregation of starch granules according to the SEM observation and decreased the enthalpy of starch gelatinization based on the differential scanning calorimetry results. The present results suggest that LREs have the potential to be utilized as a natural additive for regulating the quality of fried starchy food in food industries. Practical Application The enhancement of L. robustum polyphenols on the quality of starchy food during frying was found, and its mechanisms were also explored. This work indicated that L. robustum might be used as a novel economic natural additive for producing high-quality fried foods.

A functional yogurt was prepared with Ligustrum robustum (Rxob.) Blume extract (LRE), while its antioxidant and hypoglycemic activities were evaluated and its action mechanism was further explored. With the cofermentation of LRE, the yogurt showed the fine quality characteristics, including pH, titratable acidity, texture, syneresis susceptibility, color, microbiological content, and chemical composition. Meanwhile, the yogurt exhibited the remarkable antioxidant capability to enhance the activities of antioxidant enzymes and reduce the malondialdehyde level in animal serums. In addition, the yogurt showed the obvious hypoglycemic activity to inhibit the decrease of glucose tolerance and the increase of postprandial hyperglycemia of diabetes mice. Furthermore, using the analysis of molecular docking, the main compounds of LRE could combine tightly with α-amylase and α-glucosidase by hydrogen bond and hydrophobic interaction, so as to change their spatial structure and inhibit their biocatalytic activity in glucose metabolism. All present results suggested that LRE showed the potential value to be used as supplement to enhance the quality and functions of yogurt in food industry. Practical Application The hypoglycemic and antioxidant activities of a functional yogurt cofermented with LRE were found and its relative action mechanism was also explored. This work provide the experimental and theoretical basis for the application of this yogurt as nutraceuticals to protect human health in food industry.

This study aimed to construct zeolite/chitosan-based magnetic microparticles (MMPs) using ZSM-5 zeolite, Fe3O4, and chitosan with incorporated Ligustrum robustum (Rxob.) Blume polyphenol extract (LRE) for oil quality control. Magnetic characterization and X-ray diffraction analysis demonstrated that the obtained MMPs had a saturation magnetization of 12.07 emu/g and showed magnetic separation ability due to the presence of ferric oxide crystals. Meanwhile, MMPs exhibited good resistance against heating and had a uniform structure with an intermediate diameter of 125.79 μm. Furthermore, scanning electron microscopy and sustained-release analysis indicated that MMPs could well embed LRE and slowly release LRE in weakly polar solvents. Finally, the oil protection experiments demonstrated that MMPs could inhibit the quality deterioration of peanut oils during the frying process and show good recyclability. The findings provide promise for using magnetic microparticles in oil quality control during high-temperature processing in agriculture and food industries.

The potential uses of Ligustrum robustum (Rxob.) Blume extract as a natural antioxidant to protect the quality of different oils during storage and frying process were studied. The results showed that L. robustum extract has been shown to retard the decline in the quality of both oils based on the tests of acid value, peroxide value, p -anisidine value, color, volatile flavor, and fatty acid compositions, and the protective effect of L. robustum extract on the quality of peanut oil was better than that of palm oil. By the component analysis, L. robustum extract was found to have a total phenols content of 140.75 ± 1.52 mg/g, and ligurobustoside C was identified as the main phenolic compound. The thermogravimetric and differential scanning calorimetry results showed that L. robustum extract enhanced the oxidative stability of peanut and palm oils. In addition, Fourier transform infrared results indicated that L. robustum extract had protective effects on the C=C bond and ester bond of oil molecule. Moreover, by using electron spin resonance technique, L. robustum extract showed the ability to inhibit and scavenge alkyl-free radicals in both oils. The present results suggested that L. robustum extract may protect the quality of oils during the storage and frying process by inhibiting the oxidation of unsaturated fatty acids and might be a potential natural antioxidant in the food industry. Practical Applications The excellent antioxidant ability of Ligustrum robustum (Rxob.) Blume extract on the oxidation of different oils and its low price indicated that it could be used as a new low-cost natural antioxidant in oil processing.

We investigated the modification of wheat starch withLigustrum robustum(Rxob.) Blume extract (LRE) and determined the action mechanism. Based on differential scanning calorimetry, LRE decreased the gelatinization enthalpy of wheat starch from 19.14 to 7.15 J/g and changed gelatinization temperatures (including the variation in gelatinization onset temperature, peak temperature and conclusion temperature in different degrees). Moreover, LRE affected the pasting viscosity curve of wheat starch, and changed its rheological parameters (including the decrease in storage modulus and loss modulus, as well as the increase in loss tangent). Based on the analysis of scanning electron microscopy and wide-angle X-ray diffraction, LRE increased the hole size and the roughness of the gel microstructure, and decreased the crystallinity of wheat starch. Meanwhile, the evaluation results of the texture analyzer and the colorimeter showed that LRE could change the quality properties (including decrease hardness, fracturability andL*values, as well as increasea*andb*values) of wheat starch biscuits after hot air baking (170 °C). Furthermore, with molecular dynamics simulation analysis, phenolic compounds of LRE combined with starch molecules via H-bonds and affected the formation of molecular bonds (including intra- and intermolecular hydrogen bonds), so as to change the spatial conformation and properties of wheat starch during gelatinization and retrogradation. The present results suggest that LRE can modify the physicochemical properties of wheat starch and further improve its processing properties, indicating its potential in the design and development of starch foods (such as steamed buns, bread, biscuits, etc.).
