This study investigates whether lecithin could fasten lipolysis through the alleviation of protein aggregation in an infant formula emulsion model. Our previous study reported low intestinal digestion of infant formula could be due to the aggregation of proteins that slow lipid digestion. The emulsion contained lipids droplets simulating the fatty acid composition in breast milk, different levels of lecithin and milk protein. The interphase proteins were replaced with lecithin in a dose-dependent manner. The results showed the addition of 5% and 7% lecithin improves the physical stability, narrows the range of particle size, reduces the mean particle size and increases the zeta potential. The 5% lecithin emulsion showed the highest rate and extent of lipid and protein digestion. These positive effects were caused by lecithin through stabilizing the emulsion and suppressing droplet flocculation after digestion. Lecithin promotes lipid digestion and may improve the "insufficient fat supply" in infant formula.The aim of this study was to analyse contents of phytosterols, carotenoids, tocochromanols and fatty acid composition in oil from nutlets of linden. Standard determination methods for these compounds were applied using liquid and gas chromatography. In the analysed oils from small and large-leaved lime the dominant acids included linoleic (53.1 and 54.1%), oleic (18.5 and 22.2%), palmitic (15.3 and 11.8%). Linden seed oil was characterised by very high contents of phytosterols (2-2.5 g/100 g). β-Sitosterol was the dominant phytosterol (80-83%). Additionally squalene was detected at 806 and 607 mg/100 g, respectively, for Tilia cordata and T.platyphyllos. It was found that linden seed oil contains tocopherols (93%) and tocotrienols (7%). In terms of tocochromanol contents this oil is surpassed only by wheat germ oil. In terms of the α-T equivalent these oils contain 95 (Tilia cordata) and 50.6 mg/100 g vitamin E (Tilia platyphyllos).Freshwater scarcity is a global concern, not just in countries with limited water resources, and wastewater reuse is becoming an essential necessity. Beer is the fifth-most widely consumed beverage in the world and breweries are a major industrial water consumer. Within this study, the long-term performance of a modular pilot scale plant reusing brewery wastewater was investigated. The system consisted of a flotation device, a membrane bioreactor (MBR), an ultrafiltration (UF) and a reverse osmosis (RO) system. The system was fed with wastewater from the effluent of a full-scale anaerobic reactor. The combination of flotation device and MBR removed chemical oxygen demand (COD) by 93.6%. The subsequent UF and RO removed remaining organic load and inorganic components and process water was produced, whereby drinking water quality was achieved. A yield of 63% was reached with the pilot plant. Based on the results, a base case cost estimate was carried out for a full-scale application, taking into account the actual hydraulic load of the brewery. In order to predict the uncertainties of cost-sensitive factors, the specific costs for sludge disposal, electrical energy, freshwater supply and wastewater disposal as well as membrane lifespan and yield of the RO unit were expressed by probability distributions. Using the Monte Carlo method with 75,000 iterations, the probability distributions for the costs and economic viability of reusing brewery wastewater were calculated. The estimate found that reusing brewery wastewater can be economically viable in 77.2% of simulated cases showing the strongest dependency on costs for wastewater disposal.Surface-water irrigation is one of the most important irrigation methods in areas with abundant surface water. see more Although this method of irrigation is both economical and convenient, many contaminants are also introduced into the soil-water systems such as organophosphorus pesticides (OPPs). To study the influence of surface-water irrigation on the distribution of OPPs in soil-water systems, 42 water samples (38 groundwater and four surface water) and 85 soil samples (78 profile soil samples and seven topsoil samples) were taken from Shahu in the Jianghan Plain, China. Shahu is a typical Chinese surface-water irrigation district. During sampling, three types of areas were considered surface-water irrigated areas, groundwater-irrigated areas away from rivers, and non-irrigated areas adjacent to rivers. The results showed that the concentrations of OPPs in the groundwater and soil in the surface-water irrigated farmland were higher than those in groundwater-irrigated farmland. The groundwater flow field and surface-water irrigation were responsible for the OPPs. Thus, it is clear that the surface-water irrigation had a strong influence on the distribution of OPPs in soil-water systems. Principal component analysis for OPPs content in groundwater showed that the key influencing factors on the distribution of OPPs in groundwater were the groundwater flow field and current pesticide use.Given the increase in infrastructure construction, ecological restoration techniques need to be scientifically assessed so that appropriate measures can be taken. However, the specific effects of these techniques are often confounded by multiple ecological stressors, and robust evaluations of their effects are rare. Here, we conducted a global meta-analysis of 68 peer-reviewed publications to quantitatively evaluate the ecological impacts of roadside slope restoration techniques and explored potential mechanisms using linear regression and random-forest models. We found that roadside slope restoration techniques generally enhanced restoration effectiveness, but the recovery rate differed over space and time. Relative to the degraded reference group, the synthetic technique (63.10%) and species selection (62.09%) had more positive impacts on restoring slopes than erosion control (44.82%), seed spraying (43.55%), and substrate amelioration (12.96%). Additionally, we found that vegetation condition, soil quality, and species diversity were negatively correlated with restoration time, implying that recovery might not be stable during early restoration periods. Our findings highlighted the importance of biodiversity for restoration success, but the negative relationship between species diversity, precipitation, and age highlighted the potential risks of losing biodiversity during restoration. Finally, the importance of soil substrate but difficulty in restoring it suggested that restoration actions should stress soil substrate amelioration. Generally, this study provides evidence-based references to support decision making and ensure the effectiveness and sustainability of future slope restoration efforts.
