Adzuki beans are rich in phenols and flavonoids, which are of great significance for the nutritional supplementation of rice noodles. However, how to control the amount of Adzuki beans added to meet the rheological properties of rice noodles is unknown. Herein the effects of adzuki bean addition (0 % – 50 %) on the rheological properties of rice flour and the qualities of corresponding noodles were investigated. It was revealed that adzuki beans reduced the viscosity, gelatinization enthalpy, storage modulus ( G' ) and loss modulus ( G" ) values of the mixed flours. The resistant starch content increased from 23.74 % to 44.67 %, and the predicted glycemic index (pGI) decreased from 80.24 to 54.81. Adding 20 % adzuki beans had a minor impact on sensory quality while reducing pGI. Adzuki beans weakened the ability of starch to bond with water molecules, but shortened the optimal cooking time and quickly restored the elasticity of rice noodles.

The effect of dry heat (DH, 130 °C, 1, 3 and 9 h), cold plasma (CP, 40 V, 1, 5 and 10 min) and their combination (D-P) treatment on the structure, physicochemical and digestive properties of red adzuki bean starch were studied. The results showed that DH or CP had slight change in morphology while diffraction pattern of starch was remained. With the extension of treated time of DH and CP, the amylose content, crystallinity, molecular weight, short-range order, the long chain of amylopectin, enthalpy value, swelling power, digestibility were reduced, while gelatinization temperatures, the short chain of amylopectin and solubility were increased. The D-P had deeper modification than the single treatment. The combination of dry heat and cold plasma is a simple and green method to improve the starch structure and enhance starch properties and this modified starch could be implemented to tailor starch to the desired food applications.

Detailed characterization in nutrients and phytochemicals with antioxidant activities of 26 kidney beans was performed. The kidney beans contained high levels of dietary fiber (29.32–46.77%), resistant starch (9.16–18.09%) and protein (22.06–32.63%) but low levels of lipid (1.05–2.83%) and sugars (1.55–9.07%). The monosaccharide composition of soluble fiber was dominated by arabinose , galactose , mannose and galacturonic acid . The ratio of essential amino acid to the total amino acid was ranged from 0.29 to 0.36. The predominant fatty acid was polyunsaturated fatty acids , accounting for 47.54–67.26% of total fatty acids. The total tocopherol content was in the range of 12.83–68.35 μg/g, predominantly γ-tocopherol, followed by δ-tocopherol. In addition, certain levels of total phenolics and flavonoids with respective values of 0.25–3.79 mg gallic acid equivalent/g dry weight and 0.19–7.05 mg rutin equivalent/g dry weight resulted in significant antioxidant activities. And a good correlation was observed between TPC and FRAP values (R2 = 0.8030). The results indicated that kidney beans are excellent sources of health-promoting compounds.

The fruit (aril) of the endangered genus Taxus plants is an abandoned herbal resource. Traditionally, people enthusiastically focus on its bark, its renewable, tremendous arils fall into the soil with seeds after they are mature. The present research investigated the fruit of two species from the genus Taxus , Taxus chinensis var. mairei , and Taxus media , with regards to their antioxidant and antihyperglycaemic activities, safety, and bioactive constituents. Results showed that T . chinensis var. mairei and T . media both had certain biological activities with T . chinensis var. mairei better in antioxidant activity and T . media better in antihyperglycaemic activity. Correlation analysis revealed that the differences in bioactivities depended on content of their mainly chemical components. The mice acute oral toxicity test indicated that the methanol extracts of the two biotypes of Taxus were safe. And nineteen compounds were tentatively assigned from the two varieties, via tandem mass spectrometry using a LC-ESI-Q-TOF-MS instrument, which included phenols, flavonoids, and terpenes. These results indicate a possible application of Taxus fruit extracts in various fields like in food industry, however, this still needs further investigations. Graphical

Alternating current (ACEF), direct current (DCEF) and pulsed (PEF) electric field (EF) were applied for adzuki bean protein (ABP) pretreatment to prepare substitutes of steamed egg custard. Emulsion gels of EF pretreated ABP dispersions with flaxseed oil were mediated by transglutaminase (TGase). The emulsion particle size and the oil droplet size increased with the oil portion. PEF and ACEF pretreatment significantly reduced the number of large droplets. With the increase of oil portion, the infrared spectra at 2854 and 1747 cm −1 changed significantly and a new peak emerged in amide A zone. Three EF pretreatments all increased the β-sheets of ABP, ACEF pretreatment led to the random coils slightly higher than DCEF and PEF. DCEF pretreatment increased the α-helices significantly higher than ACEF and PEF. The EF pretreatments improved the emulsion gel texture in gel strength, hardness, and chewiness, and water holding capacity (WHC). The largest apparent viscosity and energy storage modulus were obtained in DCEF pretreatment and larger than PEF and ACEF pretreatments. The 0.15 % curcumin and 0.10 % β-carotene pigmentation of ABP-flaxseed oil emulsion gel gave the smallest difference in colour, and higher WHC, close springiness, slightly lower chewiness, and gel strength, compared with the real steamed chicken egg custard control.

The ancient gymnosperm genus Taxus is the exclusive source of the anticancer drug paclitaxel, yet no reference genome sequences are available for comprehensively elucidating the paclitaxel biosynthesis pathway. We have completed a chromosome-level genome of Taxus chinensis var. mairei with a total length of 10.23 gigabases. Taxus shared an ancestral whole-genome duplication with the coniferophyte lineage and underwent distinct transposon evolution. We discovered a unique physical and functional grouping of CYP725A s (cytochrome P450) in the Taxus genome for paclitaxel biosynthesis. We also identified a gene cluster for taxadiene biosynthesis, which was formed mainly by gene duplications. This study will facilitate the elucidation of paclitaxel biosynthesis and unleash the biotechnological potential of Taxus .

Curcumin, a bioactive compound characterized by its limited solubility in water and low bioaccessibility, which requires an effective delivery system to enhance stability and absorption. This research focused on creating Pickering emulsions stabilized by zein-adzuki bean seed coat polyphenol-sodium alginate composite nanoparticles (ZAS) to improve curcumin delivery. The effects of different concentrations of sodium alginate (SA) on the properties of ZAS were investigated. Fourier transform infrared spectroscopy (FTIR) showed that there were hydrophobic and hydrogen bonds interactions between SA and nanoparticles, and Differential Scanning Calorimetry demonstrated an improvement in thermal stability. Accelerated oxidation experiments showed that ZAS stabilized Pickering emulsions had good anti-oxidant capacity. In comparison to the control group, the addition of SA increased the loading rate of curcumin to 81.65 ± 1.56 % with improved bioaccessibility (27.99 ± 0.26 %) and in vitro digestion stability (55.72 ± 0.22 %). The findings indicate that ZAS nanoparticles modified with SA markedly enhance the stability of Pickering emulsions, while also attaining a high loading efficiency of 81.65 % and bioaccessibility of 27.99 %. This suggests their potential utility in functional food applications.

In response to the escalating plastic pollution crisis, the development of high-performance biodegradable materials is critical. Poly(butylene succinate) (PBS) is an important biodegradable polymer as it possesses excellent biodegradability and processability. But it suffers from limitations such as low mechanical strength, poor thermal stability, and high production costs. In this study, taxus residue (TF), a waste by-product, was utilized as a reinforcing filler to reduce PBS costs while enhancing its overall performance. To address the interfacial incompatibility between TF and PBS, branched PBS (T-PBS) was introduced as a compatibilizer. The TF was surface-modified via alkali treatment and silane coupling (KH550), and a series of PBS/TF/T-PBS composites with varying T-PBS viscosity grades were prepared by melt blending. The compatibilization mechanism of T-PBS and its influence on the composite structure, crystallization behavior, thermal stability, rheological, and mechanical properties were systematically investigated. Results show that the branched structure significantly enhanced T-PBS melt strength and reactivity. The introduction of T-PBS effectively improved interfacial compatibility between TF and PBS matrix, reducing phase separation and interfacial defects. Compared to uncompatibilized PBS/TF composites, those with appropriately viscous T-PBS exhibited improved tensile strength (increased by 19.7%) and elongation at break (increased by 78.8%), while flexural strength was also maintained at an enhanced level. The branched points acted as nucleating agents, increasing the onset temperature and degree of crystallinity. In the high-temperature region, the synergistic barrier effect from TF and char residue improved thermal stability (T85%reached 408.19 °C). Rheological analysis revealed enhanced viscosity and elasticity of the system. This study provides a promising strategy and theoretical foundation for the high-value utilization of taxus waste and the development of high-performance biodegradable PBS-based composites.

In this work, the superparamagnetic Fe 3 O 4 particles prepared by the coprecipitation method were coated successively by SiO 2 , vinyl end groups and molecularly imprinted polymer (MIP) shells to afford a pomegranate-like core/shell superparamagnetic particle (Fe 3 O 4 @SiO 2 @MIP), and the MIP shell preparation conditions were optimized by multi-objective response surface methodology. In order to simultaneously enrich and separate the four taxoids (10-DAB, baccatin III, cephalomannine and paclitaxel), cephalomannine was selected as the template because of its similar chemical structure to other three taxoids and relative inexpensiveness. Especially, to avoid template leaking which may influence the accuracy of identification and quantitation of the analytes, we selected paclitaxel as the target molecular during the investigation of the adsorption property of Fe 3 O 4 @SiO 2 @MIP particles. This strategy was similar to the dummy molecular imprinting technique in which the dummy molecularly imprinted polymer was prepared by using a dummy template, structural analog of the target analyte. The as-prepared Fe 3 O 4 @SiO 2 @MIP particles were characterized by transmission electron microscopy (TEM), vibrating sample magnetometer (VSM), and Fourier transform infrared spectroscopy (FTIR). The adsorption kinetics, isotherms and reusability were also investigated. Finally, the Fe 3 O 4 @SiO 2 @MIP particles were successfully applied to simultaneously enrich and separate these four taxoids in the extract of Taxus × media ( T. × media ).

Taxus species are well-known for paclitaxel, which exhibits antitumor activities and is used for treating various cancers. Although most Taxus species are widespread in many areas, few studies have characterized the variation in metabolism among different Taxus species. Using an integrated approach involving ‘tandem mass tag’ labeling and liquid chromatography–tandem mass spectrometry (HPLC–MS), proteomes of T. media and T. mairei were investigated and 4078 proteins were quantified. Screening and classification of differentially expressed proteins revealed many metabolism-associated proteins. In detail, four enzymes involved in the flavonoid biosynthesis pathway were predominantly expressed in T. mairei. Four enzymes associated with supplying precursors for paclitaxel biosynthesis and three cytochrome P450 taxoid oxygenases were preferentially expressed in T. media compared with T. mairei. Furthermore, variations in taxoid contents between T. media and T. mairei were determined using HPLC–MS analysis. Variations in flavonoid contents between T. media and T. mairei were determined by HPLC analysis. A number of differentially expressed proteins may provide an explanation for the variation in metabolisms of different Taxus species.

Paclitaxel (PTX), an active anticancer compound derived from Taxus cuspidata , possesses considerable economic value. Given the abundance of structural analogs, the selective separation of PTX from T. cuspidata presents a formidable challenge. In this study, the bifunctional monomers magnetic molecular imprinted polymers (MMIPs) with multiple active sites were synthesized using Fe 3 O 4 as the magnetic carrier, PTX as the template, 4-vinylpyridine (4-VP) and methacrylic acid (MAA) as the first-stage and the second-stage pre-assembly functional monomer, respectively. The results indicated that MMIPs exhibited excellent magnetic recovery capability and high adsorption capacity for PTX. Furthermore, the adsorption behaviors were more consistent with Langmuir isotherm model and pseudo-second-order kinetic model. The MMIPs possessed significantly higher selectivity for PTX than five structural analogs (Docetaxel, Baccatin III, 10-Deacetylbaccatin III, and Glucose) and recyclability for up to six cycles. Additionally, the adsorption mechanism analysis indicated that the excellent performance of MMIPs primarily arises from the multiple active binding sites involving hydrogen bonding and π-π stacking. Finally, MMIPs were used for PTX recognition and separation in T. cuspidata extracts. This study provides an efficient method and valuable theoretical basis for the highly selective separation of PTX from T. cuspidata.
