Regulation of dietary nutrient fractions to control the release of labile manure pollutants in swine production remains a challenge. Feeding trials were conducted to assess the impact of dietary nutrient fractions on labile manure composition and pollution potential in pigs at different growth stages. The pigs were selected based on age (weaning = 60 days, feeding = 100 days, and finishing = 160 days), health, and average body weight (23.

Physical field-assisted deep eutectic solvent processing: A green and water-saving extraction and separation technology.

J Food Sci

December 2024

Food Science and Nutrition Programme, Food Science and Microbiology Department, College of Pure and Applied Sciences, Landmark University, Omu-Aran, Nigeria.

Extraction of organic and bioactive compounds from plant materials with the traditional organic solvents aided by water or oil bath heating is not sustainable, because it consumes a lot of energy, time, water/oil, solvents, and results in lower yield. This review discusses deep eutectic solvent (DES) as a green solvent, physical field technology (PFT) as a water-saving and green technology, and how the coupling of PFT (ultrasound [US], microwave [MW], infrared [IR]) to DES will improve the yield and quality of protein, polysaccharides, polyphenols, pectin, and terpenoids extracted from plant materials. Ultrasonication increases DES extraction efficiency via cavitation dislodgement and pores creation.

The study was conducted to evaluate the nitrogen utilization efficiency (NUE) of open-pollinated maize cultivars under low nitrogen soil conditions. It took place at the Lower Niger River Basin Development Authority in Ilorin, Nigeria, during the 2019 and 2020 cropping seasons. The nitrogen treatments (0, 45, and 90 kg N ha⁻) were assigned as the main plots, while the genotypes were designated as sub-plots in a split-plot design.

Alzheimer's disease (AD) is an age-associated neurodegenerative condition marked by amyloid plaques, synaptic dysfunction, and neuronal loss. Besides conventional medical care, herbal therapies, both raw and refined, have attracted researchers for their potential therapeutic effects. As a proof-of-concept, our study combined HPLC-DAD analysis of bioactive constituents, network pharmacology, molecular dynamics (MD), molecular docking, post-MD analysis, and experimental verification to investigate the mechanisms of crude drug formulations as a therapeutic strategy for AD.

Infertility has become a significant health burden around the globe as it is believed that 15 % of married couples struggle with infertility, with half of the problem accrued to the male. The issue of male infertility could be traced to insufficient or absence of spermatozoa. Glucose metabolism is essential for continued spermatogenesis and for the reproductive potential of sperm cells.

Article Synopsis
  • The study investigates the safety and toxicity of snail slime by following OECD 425 guidelines, focusing on its acute toxicity effects in Wistar rats.
  • Eighteen rats were divided into control and treatment groups, receiving either 2000 mg/kg or 5000 mg/kg of the slime extract, and observed over 14 days for behavioral changes and organ health.
  • Results showed no deaths or significant behavioral changes, but mild cellular distortions in vital organs were noted, indicating that while the slime extract is relatively low toxic, further research is necessary before using it in traditional medicine.

Seasonings like garlic, ginger, and scallion provide spicy and masking flavor or aroma in vegetables. However, the method or technique used for drying these spices can affect the flavor profile. Therefore, this review focuses on vegetable seasonings like ginger, garlic, and scallion, the characteristic flavor of fresh and dehydrated vegetable seasoning, and how drying methods (freeze-drying [FD], convective hot air drying [HAD], infrared drying, microwave drying [MW]), and other recent dryers (swirling fluidized bed [SFB], pulsed-vacuum dryer, relative humidity-convective dryer, etc.

The study evaluated the combined effects of drying methods (air drying [AD], hot AD [HAD], microwave drying [MD], and freeze-drying [FD]) and ultrasonication parameters (sonication temperature [STemp]: 40, 50, and 60°C) and heating time (STime: 60 and 120 min) on natural deep eutectic solvent (NADES) extraction of phytochemicals from Amaranthus hybridus stem. Increasing the STemp increased the extraction yield (ECY) of the phytochemicals for all drying methods but increase in the heating time reduced the ECY slightly. MD combined with 60°C ST showed the highest ECY (53%), whereas HAD combined with 40°C ST had the lowest ECY (18%).

So far, the use of artificial low-calorie sweeteners, like sucralose, saccharin, and so on, to replace the conventional-based sugars has not succeeded due to the long-term adverse health effects, for example, hypertension, and not well-known safety stand. In this review, we discussed the next generation SvGl (rebaudioside M [Reb M]), their biosynthetic pathway in plant, high-yield production via microbial fermentation and enzyme engineering, physicochemical properties, taste modification, kinetic metabolism, application in food and beverages, safety and toxicological evaluation, regulation and dosage recommendation, and health benefits. In stevia, the biosynthesis of stevia glycosides, especially Reb M, is derived from the bifurcation of the pathway leading to gibberellin, followed by subsequent enzymatic modification of rubusoside.
