Simple SummaryHigh levels of inorganic Zn were supplemented to meet the nutritional requirements of Zn in piglets, which results in the development of intestinal microbial resistance and environmental pollution. Previous research indicated that organic Zn sources had higher bioavailability than inorganic Zn. There is limited information on the comparison of dietary Zn source dissolved in water with other Zn supplementation forms in piglets. Therefore, the present study was designed to compare the effects of three Zn supplementation forms (Zn-Met in the feed, ZnSO4in the feed, and ZnSO4dissolved in drinking water) on growth performance, Zn accumulation, activities of Zn-containing enzymes, expression of MT, and Zn transporters in piglets. In conclusion, Zn-Met and ZnSO4dissolved in drinking water had higher bioavailability in piglets.AbstractThe study aimed at determining the effect of different zinc (Zn) supplementation forms on Zn accumulation, activities of Zn-containing enzymes, gene expression of metallothionein (MT), and Zn transporters in piglets. Eighteen piglets were randomly divided into three groups: (a) a basal diet supplemented with 150 mg/kg Zn from Zn methionine (Zn-Met) in the feed (Zn-Met group), (b) a basal diet supplemented with 150 mg/kg Zn from Zn sulfate (ZnSO4) in the feed (ZnSO4,feedgroup), and (c) a basal diet supplemented with the same dose of Zn as in ZnSO4,feedgroup but in water (ZnSO4,watergroup). The results showed that Zn-Met added in feed and ZnSO4dissolved in drinking water significantly improved (p< 0.05) the Zn concentration in liver and jejunum and the apparent digestibility of Zn in comparison with the ZnSO4added in feed. In addition, dietary Zn supplementation as Zn-Met significantly increased (p< 0.05) the activity of alkaline phosphatase (AKP) in the jejunum of piglets in comparison with the ZnSO4,feedgroup. Furthermore, the Zn-Met and ZnSO4,watergroups showed an improved total superoxide dismutase activity (T-SOD) in the ileum as compared to the ZnSO4,feedgroup. Meanwhile, the qPCR and western blot results showed that Zn-Met and ZnSO4dissolved in drinking water increased the expression of MT in the jejunum in comparison with the ZnSO4added in the piglets’ feed. However, different Zn supplementation forms had no effect on the mRNA expressions of Zip4 and ZnT1 transporters. In conclusion, Zn-Met added in feed and ZnSO4dissolved in drinking water had higher bioavailability in piglets.Keywords:zinc;zinc methionine;metallothionein;mineral concentration;pig

Research on soybean nutrition is crucial for Chinese agriculture and public health, as soybean sprouting enhances its nutritional value. However, the relationships between grain quality and soybean varieties are not yet fully understood. In this study, the quality of 49 soybean cultivars from 15 different origins was evaluated through multiple correlation analysis. Differences were observed based on their geographical origin, with Shandong Chongwen showing higher calcium and isoflavone levels than the others. A correlation was found between protein content and soybean daidzein (0.561***), as well as genistein (0.597***). Additionally, sprouting was shown to improve soybean nutrition. Among six high-nutrient soybean varieties, increased levels of protein, minerals, and isoflavones were observed during germination. Phytic acid and oligosaccharide levels decreased by 64.7% and 94.5%, respectively, while saponin increased by 106.0%, indicating changes in antinutritional factors. The experiment establishes a clear relationship between soybean nutrients and the tested variables, highlighting the impact of germination on soybean quality and nutrient content.

Background: There are a substantial number of papers in the scientific literature reporting on the chemical composition of the Aloe vera plant. None of these investigations are truly comprehensive nor address the differences in composition that occur through processing variations in fresh leaves and commercially available product forms. Objectives: This work was to analytically examine a range of these forms and compile the findings. Methods: Fresh A. vera leaves and a number of commercial aloe juice powders were investigated for their major chemical constituents. Samples included fresh leaves from China and Mexico, plus commercial powders from different manufacturers made from different plant parts and/or manufacturing processes. The test results include moisture, ash, fiber, protein, lipids, minerals, organic acids, free sugars, and polysaccharides. The analytical methods employed comprise inductively coupled plasma-optical emission spectroscopy for minerals, high-performance anion-exchange chromatography equipped with pulsed amperometric detection for free sugars, HPLC for organic acids, and size exclusion chromatography (SEC)–multi-angle laser light scattering (MALS)–differential refractive index (dRI) for polysaccharide analyses. The absolute MW and MW distribution were determined using MALS measurement. Results: The major constituents of A. vera fresh leaf are fibers, proteins, organic acids, minerals, monosaccharides, and polysaccharides, which accounted for 85–95% of the total composition determined. In the commercial powdered aloe juice samples, four major components—organic acids, minerals, monosaccharides, and polysaccharides—accounted for 78–84% of the total composition. Apart from the four major components, products manufactured by ethanol precipitation contained high amounts of fiber and protein, while the free sugars were removed. In ethanol-precipitated products, the polysaccharide MW was less affected by manufacturing conditions and the concentration of aloe polysaccharides was higher than in products made in the nonethanol manufacturing processes. The overall chemical profiles were found to be consistent, except for the MW and content of polysaccharides in the commercial aloe samples analyzed, which were largely dependent on the types of manufacturing processes employed. Conclusions: This present study provides a comprehensive investigation of the major chemical composition of A. vera leaf and commercially derived products. The use of the SEC combined with MALS and differential RI detectors has proved to be an improved tool for the accurate determination of polysaccharide MW and contents of the various commercially available A. vera products in this study.

Biochars that were produced from pig manure at two different temperatures were incubated with three different minerals to examine the effects of soil minerals on biochar properties and sorption capacities. Biochars freshly mixed with minerals showed dramatic decreases in the sorption of atrazine (maximum decrease by 70.9% at C e = 0.5 S w ) and phenanthrene (maximum decrease by 69.5% at C e = 0.5 S w ) compared to unmixed biochars. Following the incubation, minerals were tightly attached to the biochar surface and insert into inner pores, thus changing the elemental composition and surface area of biochars in a manner dependent on the types of biochars and minerals involved. The changes in biochar properties in turn affected biochar sorption capacities. The sorption of both atrazine and phenanthrene by the pig manure biochar produced at 300 °C (BC300) decreased after aging due to an increase in surface hydrophilicity. In contrast, the sorption of atrazine and phenanthrene by BC700 increased after aging with minerals, which could be attributed to the increase in surface area caused by the minerals. However, the sorption capacities of the aged BC700 were still lower than those of the fresh BC700.

Pet foods are gaining ground in China. Canine milk substitute formulations are based on their milk chemistry. This study aimed to analyze and compare the differences in proteins, fatty acids, minerals, and basic chemical composition between canine, bovine, and caprine milk. Canine milk contains higher contents of protein (6.62–17.34%), fat (8.92–14.31%), and ash (1.11–1.81%), and a lower content of lactose (1.56–3.92%) compared to bovine and caprine milk. The protein profiles of canine, bovine, and caprine milk were similar as confirmed by sodium dodecyl sulphate-polyacrylamide electrophoresis gel (SDS-PAGE). The quantification of proteins in canine, bovine, and caprine milk were significantly different when analyzed by inverse high-performance liquid chromatography. Canine milk showed higher contents of monounsaturated fatty acids (29.71–32.95% of total fatty acids) and polyunsaturated fatty acids (16.83–20.56% of total fatty acids), but a lower proportion of saturated fatty acids (47.57–53.18% of total fatty acids) than bovine and caprine milk. The essential fatty acids ARA and DHA were also found in canine milk in the ranges of 0.82–1.77% and 0.12–0.43% of total fatty acids, respectively. Canine milk had higher levels of Mg, K, Na, Fe, and Zn than those in bovine and caprine milk. The nutrient profile of canine milk was different from that of bovine and caprine milk. There were differences in nutritional compositions of the milk samples from four breeds, and Rottweiler milk had the highest nutritional content. The data of this study may provide useful information about the nutritional needs of puppies during their first months of life and the basic information for formulations of puppy milk substitutes.Keywords:canine milk;chemical composition;protein;fatty acids;mineral

Variations in the quality of brewing water profoundly impact tea flavor. This study systematically investigated the effects of four common water sources, including pure water (PW), mountain spring water (MSW), mineral water (MW) and natural water (NW) on the flavor of Tieguanyin tea infusion. Brewing with MW resulted in a flat taste and turbid aroma, mainly due to the low leaching of tea flavor components and complex interactions with mineral ions (mainly Ca 2+ , Mg 2+ ). Tea infusions brewed with NW exhibited the highest relative contents of total volatile compounds, while those brewed with PW had the lowest. NW and MSW, with moderate mineralization, were conducive to improving the aroma quality of tea infusion and were more suitable for brewing both aroma types of Tieguanyin . These findings offer valuable insights into the effect of brewing water on the sensory and physicochemical properties of oolong teas.

Fe 3+ -mediated coal-assisted water electrolysis (CAWE) for hydrogen production is an effective way to utilize coal resources. Low-rank coal, which has a high abundance, is rich in mineral matter and oxygen-containing functional groups (OGs). To promote the development of Fe 3+ -mediated CAWE of low-rank coal, the roles of mineral matter and OGs in Fe 3+ -mediated CAWE are investigated in this study. Besides, to understand the reaction mechanism of coal electrolysis and provide guidance for the effective use of electrolyzed coal, the microstructural, surface structure, and microcrystalline changes of the coal are analyzed via Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and X-ray diffraction, respectively. The results show that minerals and OGs have a positive and negative influence on the Fe 3+ -mediated CAWE, respectively. The hydrogen yields of demineralized coal and oxidized coal are 33.15% and 68.47% lower than that of raw coal owing to the influence of minerals and OGs, respectively. After electrolysis, the degree of aromatic ring condensation increases whereas coal rank decreases; the content of –OH on the coal surface increases and the composition of organic sulfur on the coal surface is altered; and the crystallite diameter of the coal changes.

This study investigated the difference of nutrient composition in Caulerpa lentillifera collected from different regions. The nutrient compositions of C. lentillifera from China’s Hainan and Shandong provinces were determined and compared with those from Semporna (Malaysia), Sabah (Malaysia), Petchburi (Thailand), and two other species of seaweeds (Malaysia). The results showed that the polysaccharide and protein contents of C. lentillifera from Hainan (44.82%±0.98% and 12.5% ±0.70%), Shandong (43.22% ±1.42% and 14.7% ±0.72%), Petchburi (59.27%±2.31% and 12.49%±0.30%), and Sabah (44.02%±2.01% and 19.38%± 1.48%) were higher than those of Eucheuma cottonii (26.49%±3.01% and 9.76%±1.33%) and Sargassum polycystum (33.49%± 1.70% and 5.40% ± 0.07%), respectively. The polyunsaturated fatty acid contents in C. lentillifera from Hainan (29.98%) and Shandong (22.11%) were higher than that in Semporna (16.76% ± 0.27%), Sabah (9.49%), and S. polycystum (20.34% ±0.43%), but lower than that in E. cottonii (51.55% ± 0.57%). In Caulerpa lentillifera of Hainan and Shandong provinces, the essential amino acid (EAA)/total amino acid (TAA) ratios were 35.22% and 38.78%, respectively; and the EAA/ETAA ratios were 54.36% and 63.35%, respectively. The EAA composition of C. lentillifera was close to the ideal model of Food and Agriculture Organization/World Health Organization. C. lentillifera was rich in mineral elements, including calcium ((3315.85 ±127.55) mg (100 g) −1 and (3728.35 ±92.38) mg (100 g) −1 ), magnesium ((6715.74 ± 82.58) mg (100 g) −1 and (8128.59 ± 242.72) mg (100 g) −1 ), and trace elements, including iron ((510.65 ±5.47) mg (100 g) −1 and (1972.97 ±183.35) mg (100 g) −1 ), selenium ((1.04 ±0.08) mg (100 g) −1 and (0.83 ±0.15) mg (100 g) −1 ), and zinc ((33.90 ±0.13) mg (100 g) −1 and (11.75 ±2.05) mg (100 g) −1 ). These results showed that C. lentillifera was more nutritious than S. polycystum or E. cottonii in terms of polysaccharide, protein, and fatty acid contents. Furthermore, both C. lentillifera species collected from Hainan and Shandong provinces show more basic nutrients. Therefore, C. lentillifera has important development and application prospects.

Nanofiltration (NF) membranes have a high removal rate for pharmaceutical and personal care products (PPCPs) in drinking water, but they also reject critical minerals (e.g., calcium and magnesium) that are beneficial to health. Herein, polyethersulfone (PES)/sulfonated polysulfone (SPSf) loose NF membranes were fabricated using non-solvent induced phase separation (NIPS) to enable efficient rejection of PPCPs while preserving high mineral permeability. The resultant loose NF membrane showed increased negative charge owing to the -SO 3 - groups of SPSf. It also exhibited a high water permeance of ∼20.8 L m -2 h −1 bar −1 characterized by high PPCPs/minerals selectivity ( i.e. , rejection of PPCPs > 90 % and rejection of Mg 2+ < 5 %). The filtration performance of resultant membrane indicated that the ionic PPCPs (e.g., Indomethacin, Diclofenac Sodium, Levofloxacin, Norfloxacin) were removed by the electrostatic repulsion and adsorption, while the removal of non-ionic PPCPs (e.g., Bisphenol A, Carbamazepine) was primarily dominated by the synergy of adsorption and size exclusion. Therefore, the superior removal rate of hydrophilic PPCPs was due to enhanced PPCP-membrane adsorptive interaction. This study provides a profound understanding of the selective separation mechanism of loose NF membranes for micropollutants and minerals.

Transforming to biochar provides an environmentally friendly approach for crop residue reutilization, which are usually applied as sorbent for heavy metal removal. As typical silicon-rich material, the specific sorptive mechanisms of rice straw derived biochar (RSBC) are concerned, especially at the low concentration range which is more environmentally relevant. In the present study, Cd sorption onto RSBCs at the concentration of ≤ 5 mg/L was investigated. The sorptive capacity was positively correlated with the pyrolytic temperature of the biochar and the environmental pH value. Water soluble minerals of the RSBCs played the dominant roles in Cd sorption, contributing 29.2%, 62.5% and 82.9% of the total sorption for RSBCs derived under 300°C, 500°C and 700°C, respectively. Increased number of cations, dominantly K + , were exchanged during the sorption. Coprecipitation with cations and carbonates may also be contributive to the sorption. The dissolution of silicon-containing minerals was found to be declined during sorption, suggesting its involvement in the sorption process, possibly through precipitation. Whilst, the sparingly soluble silicate crystals may impose ignorable role in the sorption. Complexation with organic groups is only a minor mechanism in Cd sorption, compared to the much more dominant roles of the inorganic ashes.

In recent years, biochar has been well-documented in the literature as a promising soil amendment for the sorption and immobilization of organic contaminants in contaminated soils via its organic functional groups. In this study, original and demineralized cow manure biochars were applied with the aim to evaluate the impact of their mineral component on adsorption and competitive adsorption of oxytetracycline and carbaryl. Adsorption increased greatly for oxytetracycline but decreased slightly for carbaryl after demineralization. Mineral components significantly enhanced overall adsorption of carbaryl but slightly inhibited that of oxytetracycline to biochars, because the dominant sorption mechanisms of oxytetracycline and carbaryl on demineralized biochars were established as pore-filling effects and specific-site sorption, respectively. Competitive adsorption was observed in the binary-solute sorption system, where oxytetracycline outcompeted carbaryl on original biochars, however, carbaryl showed a greater competitive adsorption to oxytetracycline on demineralized biochars. Furthermore, demineralization treatment weakened the competition strength of oxytetracycline to carbaryl but enhanced that of carbaryl to oxytetracycline. This work demonstrated that the demineralization treatment altered the physicochemical properties of biochars and the dominant sorption mechanisms of oxytetracycline and carbaryl, leading to their different changes on competition strength. The results are useful for the application of biochars in the remediation of combined pollution in agricultural soils.

Mei (Prunus mume) is widely planted in Eastern Asian countries. To evaluate the effect of cultivar and producing origin on the quality of Mei fruit, we studied the phytochemical properties and antioxidant activities of the 16 Mei fruit cultivars from 6 provinces in China, as well as their profiles of 121 volatile compounds, 5 organic acids, 13 minerals, 24 amino acids and 3 active peptides. Multivariate analysis revealed that the four Mei fruit cultivars with a drier climate in Yunnan province had the characteristics of low water moistures and proteins contents, high total acids, soluble solids, flavones, and phenols contents, and high antioxidant activities, which could be distinguished from fruits of other producing areas. Further component analysis showed that Mei fruits were rich in volatile compounds, organic acids (such as citric acid and malic acid), minerals (such as K, Ca, Mg, P, and Fe), and amino acids (such as Orn, Asn, and Asp), and the nutrient composition ratio in different cultivars was different. In conclusion, Mei fruits can be used as nutritious health food and different cultivars focus on different nutritional compositions.
