This study investigated the effects of cold plasma (CP) treatment on the inactivation of yam peroxidase (POD) and its impact on the structure and quality characteristics of yam slices. Under the CP condition of 500 W, 3 mm, 5 mm and 7 mm yam slices showed the lowest POD activity at 90 s, 120 s and 180 s, respectively. Further, the mechanism of POD inactivation was explored by observing the conformation and morphology changes of horseradish peroxidase (HRP) after CP treatment. Microscopic images and scanning electron microscopy showed that the yam surface was etched after CP treatment, which was conducive for water evaporation. Finally, CP effectively retained quality properties and antioxidant activity of yam. In conclusion, CP is an excellent non-thermal processing method which can achieve the balance between enzyme deactivation and preservation of physicochemical properties of yam slices.

BACKGROUND Natural plant essential oils have antimicrobial properties; however, essential oils are difficult to maintain in a system because of their volatile nature. First, we prepared microcapsules from β -cyclodextrin and oregano essential oil and characterized their properties. Second, the effect of microcapsules on the preservation of freshly cut purple yam was studied using an edible coating technique. Purple yams immersed in distilled water were used as control, and their characteristics were compared with yams coated with citric acid, citric acid + sodium alginate, and citric acid + sodium alginate + β -cyclodextrin–oregano essential oil microcapsules (CA–SA–MC) and stored at 4 °C for 5 days. RESULTS Microcapsules of oregano essential oil and β -cyclodextrin solution were successfully prepared via the inclusion method, with an optimal encapsulation efficiency of 55.14%. Scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis showed strong bonds between β -cyclodextrin and oregano essential oil. All edible coatings, particularly CA–SA–MC, significantly ( P ≤ 0.05) maintained firmness, total soluble solids, ascorbic acid content, and anthocyanin content compared with control treatment. This treatment also prevented browning and extended the shelf life of purple yam. CONCLUSION Oregano essential oil can be successfully encapsulated into cyclodextrin microcapsules. It has a great impact on the shelf life extension of purple yam and could be successfully applied to other fresh produce. © 2020 Society of Chemical Industry

This study systematically investigated the antioxidant activities and phytochemical profiles of petroleum ether (PE), ethyl acetate (EtOAc), n-butanol (n-BuOH) and aqueous fractions of edible (tubers) and non-edible portions (peels) ofPachyrhizus erosus.The results showed that both the tubers and peels fromP. erosuswere rich in polyphenols and flavonoids, whereas the EtOAc fraction of peels had the highest polyphenol content, and the PE fraction of peels had the highest total flavonoid content. ABTS, DPPH, and FRAP assays revealed that both the EtOAc fraction of tubers and peels fromP. erosusshowed significant antioxidant activity, whereas the EtOAc fraction of peels possessed better antioxidant activity than that of tubers. UPLC-Orbitrap-MS/MS analysis indicated that thirty compounds were identified from the EtOAc fractions of peels and tubers, including twenty-one flavonoids, six phenolics, two coumarins, and one lignan, some of which have previously been revealed to display significant antioxidant and anti-inflammatory effects via the Nrf2-Keap1 and NF-κB signaling pathways. These findings provide robust scientific evidence for the health-promoting properties and pharmaceutical potential ofP. erosus, and its non-edible portion (peels) has great potential for use as a natural antioxidant in the food, cosmetic, and pharmaceutical industries.

In this study, Chinese yam ( Dioscorea opposita Thunb. ) flour was irradiated at doses of 1.79, 6.06, 10.07 and 14.97 kGy of the electron beam, to analyze the effects of electron beam irradiated (EBI) on the solubility, transmittance, swelling, paste properties, and the microstructure of starch in yam flour. Results showed that EBI degraded the starch component of yam flour, and presented an increase in solubility from 15.59 to 30.05%, transmittance from 8.11 to 11.63%, and a decrease in swelling from 9.59 to 7.26 g/g. Also, we observed that there was a significant decrease in the paste properties of yam flour with the elevation of EBI. The scanning electron micrographs and Fourier transforms infrared spectra further illustrated the effect of EBI on the molecular structure, but not the surface structure of starch in yam flour. C -type crystalline structure in yam starch was also observed in both control and treatment, while irradiated yam starch had a lower crystallinity than that of unirradiated treatments. Yam starch exhibited a decrease trend in their thermal property values with irradiation treatment. This study concludes that the physical properties of yam flour instructed by EBI may be used in a wide application in the food and pharmaceutical industrie.

An antibacterial film based on Chinese yam starch (D-sorbitol as plasticizer) incorporated with eugenol (YDE) was prepared for pork preservation. The structure of films was characterized and the evaluation of two plasticizers (glycerol and D-sorbitol) on their mechanical and barrier properties was performed to determine the vehicle of eugenol. The release behavior and antimicrobial activity of YDE were investigated and the application of the films for pork preservation was evaluated. The mechanical and barrier properties of films were dependent on plasticizer. The release of eugenol from films was well-controlled by two release mechanisms of diffusion and erosion. YDE displayed good eugenol dose-dependent antibacterial activity which was higher against E. coli than against L. monocytogenes and S. aureus . The film with 3% eugenol can extend the shelf-life of pork beyond 50%, suggesting that the film may have great potential in active packaging for extending the shelf-life of foodstuffs.

The widely use of petroleum-based plastics causes serious environmental pollution and oil resource shortage. In this work, biodegradable films were prepared based on gallic acid (GA)-induced Chinese yam starch (YS) and chitosan (CS). The fresh-keeping effect of biodegradable films on the pork meat preservation were investigated. The prepared GA/YS/CS biodegradable films exhibited thinner thickness and better light transmittance, because CS effectively decreased the viscosity of film-forming solution and weaken its internal link structure. The SEM results and mechanical results revealed that the YS, GA, and CS had a good compatibility, GA modification and adding CS markedly improved the tensile strength of YS-based film, because the interaction between CS and starch molecular was facilitate owing to the NH 3 + of CS tended to form hydrogen bonds with the hydroxyl group of starch. Sensory analysis results suggested that GA/YS/CS films can effectively improve the quality of pork during storage compared to the package of polyethylene film. In summary, the prepared GA/YS/CS film in this work had practical application potential in pork preservation due to its excellent mechanical, antibacterial, oxidation resistance properties, and the development and application of biodegradable starch film can greatly reduce the increasingly serious environmental pollution pressure.

In this work, two combinations of double EOs, i.e., α-terpineol: eugenol (α-T:Eu) and carvacrol:eugenol (CA:Eu), are used to develop the active antibacterial films of double EOs@yam starch/microcrystalline cellulose (EOs@SC). The hydrogen-bonded networks in SC matrix are conducive to thermostability enhancement and the film of SC25 is determined for EO incorporation. The interactions between EOs and SC matrix are also hydrogen bonds and the double EOs@SC are smooth at ratio of ≤2:2 for α-T:Eu or CA:Eu. The ultimate film properties are dependent on the incorporated EOs. The release of EOs is well controlled by two mechanisms of diffusion (predominant) and swelling (secondary). Synergetic antibacterial activity occurs on double EOs@SC. The shelf life of pork can be extended by 1 day at 25 °C by the two typical films of α-T 2 :Eu 2 @SC and CA 2 :Eu 2 @SC. Moreover, EOs@SC can be well degraded in humus soil. Thereby, the target films will have great potential in active packaging to extend the shelf life of food.

The aim of this work was to compare the composition and physicochemical properties (SEM, XRD, solubility, swelling power, paste clarity, retrogradation, freeze–thaw stability, thermal property, and pasting property) of three Chinese yam (Dioscorea oppositaThunb.) starches (CYYS-1, CYYS-2, and CYYS-3) in Yunlong town, Haikou, Hainan Province, China. Our results show that all the CYYS gave a typical C-type X-ray diffraction pattern. The swelling power of CYYS varied from 10.79% to 30.34%, whereas solubility index was in the range of 7.84–4.55%. The freeze–thaw stability of each CYYS showed a contrary tendency with its amylose content. In addition, CYYS-3 showed the highestTo(81.1 °C),Tp(84.8 °C),Tc(91.2 °C), andΔH(14.1 J/g). The pasting temperature of CYYS-1 increased significantly with sucrose addition. NaCl could inhibit the swelling power of CYYS. There were significant decreases in pasting temperature and pasting time of CYYS when pH decreased.Keywords:Dioscorea oppositaplants;Chinese yam starch;pasting property;freeze–thaw stability

At present, the large scale application of batch foam fractionation is still in confrontation with many problems and difficulties, especially for the enrichment of non-surface-active materials. It is difficult to select a suitable surfactant as the collector when a non-surface-active material can only form a stable association with the expensive surfactants or has not any interactions with the commercially available surfactants. The objective of this work was to investigate the feasibility of batch foam fractionation for recovering such a non-surface-active material, puerarin. Yam mucilage, an abundant byproduct from the manufacture of yam starch, was used to generate a stable foam phase based on its good foamability. According to the properties of puerarin and yam mucilage, β -cyclodextrin ( β -CD) was selected as a basic material to establish an association between them. The results of fluorescence sensitization experiments indicated that puerarin could form an equimolar inclusion complex with β -CD and the inclusion constant was 405.8. Subsequently, β -CD was modified by introducing carbon disulfide and copper (Cu) ion. Then, puerarin could be adsorbed on the gas-liquid interface in the form of ternary complex with modified β -CD-Cu ion complex and glycoprotein molecules (see Fig. 7). Batch foam fractionation was carried out by using the crude extracting solution as the initial feeding solution, in which the concentration of puerarin was as high as 4.6 g/L. Under the suitable conditions of temperature 50 °C, pH 6.0, loading volume of feed solution 400 mL, the pore diameter of gas distributor 0.450 mm, additive volume of yam mucilage 30 mL and volumetric air flow rate 100 mL/min, the enrichment ratio and the percent recovery of puerarin were 4.3 and 82.3%, respectively. This strategy could be generalized to the separation of various non-surface-active materials due to the low cost and the diversiform cavity dimension of cyclodextrins.

Clinical research has demonstrated that non-starch polysaccharides from natural sources exhibit protective and therapeutic effects on ulcerative colitis (UC). In this study, a non-starch polysaccharide (CYP-A) with a molecular weight of 1.54 × 10 3 kDa was isolated from a speciality Chinese yam ( Dioscorea ) variety, the Ma yam, consisting mainly of mannose and glucose. The results indicated that CYP-A alleviated colitis symptoms induced by dextran sulfate sodium (DSS), repaired the mucus barrier, and protected the integrity of the intestinal mechanical barrier. Furthermore, CYP-A suppressed pro-inflammatory cytokine production, reduced oxidative stress, and modulated the biological barriers by facilitating the colonization of norank_f-_Muribaculaceae , Dubosella , Faecalibaculum and Enterorhabdus, while reducing Escherichia - Shigella and Bacteroides . Notably, CYP-A reshaped the metabolic pathways related to steroid hormone biosynthesis as well as phenylalanine, tyrosine, and histidine metabolism. These findings highlight the potential of CYP-A as a nutraceutical for targeting UC and improving gut health.

This work proposed to prepare solid acid from phosphorus tailings and successfully convert Dioscorea zingiberensis C.H. Wright (DZW) into diosgenin from the perspective of solid waste resource reuse and clean production. The results showed that SiO2–SO3H solid acid could catalyze the production of diosgenin from total saponins under solvothermal reaction conditions. In addition, the parameters of a single factor, such as the amount of SiO2–SO3H, solvent volume, reaction temperature, and reaction time, were optimized to confirm the optimal range of reaction conditions, and the optimal process conditions were determined by the response surface method. The yield of diosgenin was 2.45 ± 0.17% under the optimum conditions, and the yield of diosgenin was increased by 12.90% compared with the traditional acid hydrolysis process. Except the relatively higher catalytic activity, the alcoholysis approach for the production of diosgenin has no waste liquid to discharge. The products were analyzed by high-performance liquid chromatography-mass spectrometry, and the pathway to convert total saponins into diosgenin under SiO2–SO3H has been proposed. Moreover, the adopted catalyst can be prepared with very low cost from phosphorus tailings. Considering the obvious superiorities, the alcoholysis approach in this work could be a promising strategy for green production of diosgenin as well as a possible utilization pathway of phosphorus tailings.

This study aimed to test the preventive anti-inflammatory properties of Chinese yam polysaccharides (CYP) and sulfated Chinese yam polysaccharides (SCYP) on LPS-induced systemic acute inflammation in mice and investigate their mechanisms of action. The results showed that SCYP can efficiently reduce plasma TNF-α and IL-6 levels, exhibiting an obvious anti-inflammation ability. Moreover, SCYP reduced hepatic TNF-α, IL-6, and IL-1β secretion more effectively than CYP, and significantly altered intestinal oxidative stress levels. In addition, a 16S rRNA gene sequencing analysis showed that CYP regulated the gut microbiota by decreasingDesulfovibrioandSutterellaand increasingPrevotella. SCYP changed the gut microbiota by decreasingDesulfovibrioand increasingCoprococcus, which reversed the microbiota dysbiosis caused by LPS. Linear discriminant analysis (LDA) effect size (LEfSe) revealed that treatment with CYP and SCYP can produce more biomarkers of the gut microbiome that can promote the proliferation of polysaccharide-degrading bacteria and facilitate the intestinal de-utilization of polysaccharides. These results suggest that SCYP can differentially regulate intestinal flora, and that they exhibit anti-inflammatory effects, thus providing a new reference to rationalize the exploitation of sulfated yam polysaccharides.Keywords:yam polysaccharide;sulfation;LPS;anti-inflammation;gut microbiota
