The effect of thermal pasteurization (TP), high temperature long time (HTLT), ultra-high temperature instantaneous (UHT), high hydrostatic pressure (HHP) and thermosonication (TS) sterilization on the physicochemical, sensory and functional properties of black carrot juice (BCJ) were studied. And for the first time, the comprehensive quality of sterilized BCJ was quantified by mathematical modeling. UHT was the least suitable sterilization method for BCJ resulting from the most severe deterioration in functional properties. TS had adverse effects on sensory and physicochemical properties, but significantly increased the total flavonoids and anthocyanins contents ( p < 0.05) and showed the strongest antioxidant activity, making it a nutritional high-value processing method. TP and HHP balanced the improvement of sensory properties and the retention of functional properties, which were the most suitable sterilization methods for BCJ. This study determined the optimal sterilization methods of BCJ, and provided a scientific solution for the screening of high quality processing methods.

Introduction Quality evaluation of Huang-qin is significant to ensure its clinical efficacy. Objective This study aims to establish an accurate, rapid and comprehensive Huang-qin quality evaluation method to overcome the time-consuming and laborious shortcomings of traditional herbal medicine quality assessment methods. Methods The contents of baicalin, baicalein and scutellarin in Huang-qin from five different origins were analyzed by FT-IR and NIR spectra combined with multivariate data technology. The quality of Huang-qin from different origins was evaluated by TOPSIS and consistency analysis based on the content of three active ingredients. The correlation between ecological factors and the accumulation of active ingredients was explored. Results Satisfactory prediction results of PLS models were obtained. Relatively, the model based on FT-IR combined with the PLS regression method has higher R 2 and smaller RMSE than the NIR combined with the PLS method. TOPSIS and consistency analysis results showed that the quality of Huang-qin from different geographical origins was significantly different. The results showed that the quality of Huang-qin produced in Shanxi Province was the best among the five origins studied. The results also found that the quality of Huang-qin in different growing areas of the same origin was not completely consistent. The correlation study showed that altitude, sunshine duration and rainfall were the main factors that caused the quality difference of medicinal materials in different geographical origins. Conclusion This study provides a reference for the rapid quantitative analysis of the active components of herbal medicine and the quality evaluation of them.

Introduction: Metropolitan governance’s efficacy is regularly gauged by its capability for public health preparedness, a critical component, particularly in the post-pandemic climate, as global cities reassess their mitigation abilities. This process has broader implications, curbing mortality rates and amplifying sustainability. Current methodologies for preparedness assessment lean primarily on either Subjective Evaluation-Based Assessment (SBA), predicated on experts’ input on various capacity indicators, or they opt for Data-Based quantitative Assessments (DBA), chiefly utilizing public statistic data.Methods: The manuscript discusses an urgent need for integrating both SBA and DBA to adequately measure Metropolitan Public Health Pandemics Preparedness (MPHPP), thus proposing a novel entropy-TOPSIS-IF model for comprehensive evaluation of MPHPP. Within this proposed model, experts’ subjective communication is transformed into quantitative data via the aggregation of fuzzy decisions, while objective data is collected from public statistics sites. Shannon’s entropy and TOPSIS methods are enacted on these data sets to ascertain the optimal performer after normalization and data isotropy.Results and discussion: The core contribution of the entropy-TOPSIS-IF model lies in its assessment flexibility, making it universally applicable across various contexts, regardless of the availability of expert decisions or quantitative data. To illustrate the efficacy of the entropy-TOPSIS-IF model, a numerical application is presented, examining three Chinese metropolises through chosen criteria according to the evaluations of three experts. A sensitivity analysis is provided to further affirm the stability and robustness of the suggested MPHPP evaluation model.

Camellia chekiangoleosa Hu. ( C. chekiangoleosa ) is an oil-bearing tree species with high oleic acid content and properties such as rapid oil formation. A report related to the evolution of its seed chemical composition during ripening is limited. This study investigates changes in the chemical composition of C. chekiangoleosa seeds during maturation. For this purpose, eight clones of C. chekiangoleosa fruit samples were harvested at different ripening degrees. Finally, an improved Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method was used to assess the quality of mature oils based on key analytical parameters including oil yield, fatty acids composition and lipid concomitant. The difference in the analytical parameters of the eight sample’s oils gradually decreased as ripening progressed. Moreover, during the seed development of C. chekiangoleosa , higher protein and starch content was observed at the early stages. In addition, as ripening advances, the soluble sugar content fluctuated during maturation, while the oil content increased significantly. During ripening, monounsaturated fatty acids (MUFA) increased, while polyunsaturated fatty acids (PUFA) decreased. As ripening advances, the amounts of α-tocopherol, squalene, and β-sitosterol decreased to a stable range. The PCA results further proved that the composition of C. chekiangoleosa seed oils remained almost constant after 25 August. Therefore, an improved TOPSIS based on Mahalanobis distance was used to evaluate the quality of C. chekiangoleosa seed oils collected at three time-points after maturity. Moreover, LK006 and LK32 were evaluated as better than other clones and more suitable for breeding and processing.

The wheat seedlings of 6 days old were daily subjected to ultraviolet irradiation (irradiating for 5, 10, 20, 40, and 60 min/day, respectively), Polyethylene glycol 6000 (5, 10, 15, 20, 25% in 1/2 Hoagland solution, respectively), and salinity solution (10, 25, 50, 100, 200 mM in 1/2 Hoagland solution, respectively), while the control group (CK) was supplied only with the Hoagland solution. The wheatgrass was harvested regularly seven times and the total soluble polysaccharides, ascorbic acid, chlorophyll, total polyphenol, total triterpene, total flavonoid, and proanthocyanins content were tested. The antioxidant capacity was evaluated through 2,2′-azino-bis (3-ethylbenzthia-zoline-6-sulfonic acid) (ABTS), 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging ability, and ferric ion reducing power. Technique for order preference by similarity to ideal solution (TOPSIS) mathematical model was adopted to comprehensively assess the functional phytochemicals of the different treatments. The results showed that the accumulation patterns of phytochemicals under abiotic stress were complex and not always upregulated or downregulated. The antioxidant activity and functional phytochemicals content of wheatgrass were significantly affected by both the stress treatments and seedling age, while the latter affected the chemicals more efficiently. The top five highest functional phytochemicals were observed in the 200 mM NaCl treated group on the 21st and 27th day, 25% PEG treated group on the 24th day, 200 mM NaCl treated group on the 24th day, and the group of 40 min/day ultraviolet exposure on 27th day.

Rana chensinensis ovum (RCO) is an agricultural waste when producing Oviductus Ranae . The aim of this work was to evaluate the potential of RCO as a preeminent roe resource. Commercially available fish roes were employed as a nutritional measure to assess RCO. Major unsaturated fatty acids (UFAs) concentration, the ratio of n-6/n-3 UFAs, vitamin E, the ratio of vitamin E to linoleic acid (LA), antioxidant capacity, cost, and oil extraction rate were all considered throughout the evaluation. Methodology of cluster analysis, TOPSIS, and chemometrics were used in the investigation. The results showed that RCO had an appropriate ratio of n-6/n-3 UFAs of 1:1.0986 and a total amount of 30.3368 mg g −1 for seven main UFAs (rank 5/31). The measurement of the vitamin E concentration was 10.9465 ± 7.9858 mg g −1 (rank 1/31). The antioxidant capacity of RCO was rated 11 out of 31. After a thorough evaluation of all parameters with TOPSIS, RCO came in first place out of 31 different types of roes. According to this study, RCO has the potential to be a roe product available in terms of both economic viability and nutritional value. The results of this study will aid in lowering RCO waste and enhancing knowledge and use of its nutritional value. Practical Applications As a byproduct generated during the production of Oviductus Ranae , the potential nutritional value of RCO remains unexploited. The present study identified that RCO exhibits the following notable advantages: an n-6/n-3 polyunsaturated fatty acid ratio (∼1:1.1) aligning with ideal human metabolic needs; vitamin E content (10.9465 mg·g − 1 ) ranking top among 31 commercial aquatic roe samples, mitigating lipid peroxidation and active component degradation; coupled with low production costs and reduced water use. These traits position RCO as a promising premium caviar substitute or functional food, enabling high-value byproduct utilization and providing consumers with a cost-effective, nutrient-rich option.

An intelligence model using a linear hypothesis algorithm was created to calculate the blending proportions of granular green tea sourced from Zhejiang, China. Using quantitative sensory and chemical indicators, two similarity coefficients ( and ) were derived through the Factor Analysis-Technique for Order of Preference by Similarity to Ideal Solution (FA-TOPSIS) to screen appropriate candidate samples and determine the final blending proportions as comprehensive evaluation criteria. ranked the top five appropriate samples for blending, and identified the optimal blending proportions. Blending model solution was obtained using the Monte Carlo method, while integer programming was applied as a model constraint. The blending proportions, as determined by quantitative sensory indicators, resulted in the highest values. The result of quantitative descriptive analysis (QDA) validated that the blended samples closely replicated the target's taste profile. The present study investigates the blending of green tea taste, employing linear hypothesis algorithms with FA-TOPSIS to innovatively establish a digital indicator-based intelligent blending approach. This methodology is also applicable to flavor blending for other tea varieties.

A comprehensive assessment of the heavy metal system in the rehabilitated saline-alkali land holds significant importance, as the in-situ remediation process utilizing amendments substantially alters the initial physicochemical properties of the soil, which could lead to the migration or reactivation of previously stabilized heavy metals. In this context, the present study aims to evaluate the heavy metal content and health risk within the improved saline-alkali soil-plant system. Moreover, a comprehensive evaluation based on the TOPSIS-RSR method is carried out to accurately gauge the soil health status. The findings indicate that the modification process has an impact on the concentrations of heavy metals in the soil and crops, causing either an increase or decrease. However, the level of heavy metal pollution in the improved saline-alkali soil and rape remains within safe limits. The results of the migration of heavy metals after amendment application indicated that the migration of heavy metals in the soil was influenced by the properties of the heavy metals, the composition of the amendment, and leaching. Furthermore, the total non-carcinogenic hazard quotients in the soil and rape were within the safe threshold for all populations. The findings provided novel insights into the status and risk assessment of the pollution of improved saline-alkali soil.

Wild tea is highly valued for its perceived superior quality, yet scientific validation remains limited. Therefore, this study comprehensively evaluated the quality of Wuning wild tea. Compared to cultivated tea, Wuning wild tea exhibits superior essential chemical constituents, including tea polyphenols and free amino acids, and its functional component composition and quality characteristics are better. Wuning wild black tea (WBT) was shown to possess the highest quality among the 11 teas evaluated through multivariate statistical analysis and the technique for ordering preferences for similarity to ideal solutions-gray relational analysis (TOPSIS-GRA) coupled model, and to possess strong antioxidant activity. Mechanistic studies revealed that the interaction between theaflavin-3,3′-digallate (TFDG) and pepsin (PEP) follows a static quenching mechanism. UV–vis spectroscopy analysis showed that TFDG reduces the hydrophobicity of tyrosine and tryptophan residues in PEP. These results provide a scientific basis for the superior quality of wild tea.

To establish a quality evaluation system for Meconopsis integrifolia based on alkaloid components and to analyze the relationships between active ingredients and environmental factors, 138 samples from 15 origins was evaluated using the TOPSIS-entropy weighting method. Machine learning models (including PLS, SVR and BayesRidge) integrated with near-infrared spectroscopy preprocessing were employed for quality evaluation. Key environmental drivers were then identified through correlation and redundancy analysis. The results from the TOPSIS-entropy weighting indicated that samples originating from the north of Laji Mountain in Qinghai (P4 and P6) demonstrated the highest quality. Machine learning results showed that the optimal model for quality evaluation of different alkaloid components, utilizing both TQ Analyst and Python, achieved high prediction accuracy (RPD>2.8). External validation demonstrated that TQ Analyst exhibited the best predictive performance for OE and NE, whereas the Python-based approach yielded superior results for TA, PE, and AE. Overall, the Python-based models showed enhanced predictive accuracy and robustness, as evidenced by higher prediction rates, reduced MAE and MSE values, and stronger R² scores upon external validation. Spearman correlation and RDA analyses revealed the contents of alkaloid were significantly correlated with altitude, temperature, and precipitation. This study provides a scientific basis for the quality control of M. integrifolia . Additionally, the elucidated relationship between active ingredients and environmental factors lays a theoretical foundation for its protection of excellent germplasm resources and sustainable resource utilization.

Quality of Cortex Fraxini is closely related to its clinical efficacy and drug safety. Traditional quality assessment methods are either non-objective or time-consuming. It is imperative to establish a rapid method for quality detection and evaluation of Cortex Fraxini . In this study, fourier transform infrared spectroscopy (FT-IR) and near-infrared spectroscopy (NIR) combined with chemometrics were used for rapid quantitative analysis of the main active components in Cortex Fraxini . Partial least squares regression (PLSR) combined with variable select by competitive adaptive reweighted sampling (CARS) algorithm gave rise to good predictions of the content of the three active components with R 2 values greater than 0.98. Furthermore, the quality evaluation results of Cortex Fraxini cannot be simply derived from data on the content of active ingredients. This study used technique for order preference by similarity to an ideal solution (TOPSIS) method and consistency analysis to evaluate the quality of Cortex Fraxini from five geographical origins. Two methods respectively realized the quality superiority ranking and quality consistency grading of Cortex Fraxini samples. The evaluation results showed that Cortex Fraxini derived from SN had the best performance in quality and was consistent with the standard of genuine regional herbs. This study introduces an effective technique for swift identification of the primary active compounds in Cortex Fraxini , as well as for an overall assessment of its quality. The combination of spectroscopic techniques and chemometrics provides a rapid and efficient method for the quality analysis of Cortex Fraxini .

The present study was executed to analyze the functional phytochemicals of hulless barley grass grown under different intensities of ultraviolet stress. The wheat seedlings were imposed to 0.5, 1.0, 1.5, 2.0, and 2.5 h ultraviolet radiation and harvested in different times at vegetative stage. Specifically, the contents of total polyphenols, total flavonoids, total triterpenes, total polysaccharides, proanthocyanidins, and chlorophyll were determined and antioxidants capacity was evaluated by OH• and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) scavenging ability. A mathematical model (Technique for Order Preference by Similarity to Ideal Solution, TOPSIS) was also employed for the comprehensive evaluation of functional components of hulless barley grass at different growth stages. The results showed that the UV stress could efficiently improve/preserve the contents of total polyphenols, total flavonoids, total triterpenes, total polysaccharides, proanthocyanidins, chlorophyll a, chlorophyll b, and total chlorophyll, as well as the OH• and ABTS scavenging capacity. TOPSIS evaluation revealed that the highest phytochemical contents were yield on the 15th day under 1.0 h ultraviolet treatment.
