Abstract:
Background/Objectives: Metabolic profiling of tissue samples via liquid-state nuclear magnetic resonance (NMR) requires the extraction of polar metabolites in a suitable deuterated solvent. Such methods often prioritise metabolite recovery over protein removal due to the relatively low sensitivity of NMR metabolomics and the routine use of methods able to supress residual protein signals. However, residual protein may impact metabolite integrity and the metabolite stability after NMR sample preparation is often overlooked. This study aimed to investigate the effect of residual protein contamin

Background and Aim: Edible bird's nest (EBN) is the nutrient-rich salivary bioproduct produced by swiftlets in Southeast Asia. Currently, researchers are exploring the therapeutic effects of EBN, such as cell growth promotion, antioxidant content, antiviral effects, bone strengthening, eyes care, and neuroprotection bioactivities. The therapeutic effects of EBN have been studied through different extraction methods but the metabolites profile of the EBN in each extract has not yet been elucidated.

Abstract:
Metabolite extraction is one of the critical steps in microbial metabolome analysis. It affects both the observed metabolite content and biological interpretation of the data. Several methods exist for metabolite extraction of microbes, but the literature is not consistent regarding the sample model, adequacy, and performance of each method. In this study, an optimal extraction protocol for Yersinia intracellular metabolites was investigated.

Abstract:
The composition of extracts isolated from black alder bark by ‘green’ microwave assisted water extraction in the temperature range of 70–150 ℃ was studied using the wet chemistry Folin-Ciocalteu method and Py-GC-MS/FID. The composition data were compared with those of the extracts obtained at the same temperature by accelerated solvent extraction (ASE) of bark. It was shown that microwave assisted extraction, compared with ASE, resulted in more significant transition of major cell wall components, including hemicelluloses and phenolics of lignin origination, into the solution. Depending on the

Abstract:
Fruit constitutes a major component of our diet, providing fiber, vitamins, minerals, and many other phytonutrients that promote good health. Fleshy fruits, such as tomatoes, already contain high levels of several of these ingredients. Nevertheless, efforts have been invested in increasing and diversifying the content of phytonutrients, such as carotenoids and flavonoids, in tomato fruits. Increasing levels of phytonutrients, such as lycopene, is highly justified from the perspective of the lycopene extraction industry due to cost effectiveness reasons. Diversifying phytonutrients, in particul

Abstract:
The objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) on the internal surfaces of metallic natural gas pipelines. The goal is one or more products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this year has been to evaluate a number of methods to fractionate and concentrate the components found in the pepper extracts. The separation methods considered include size exclusion chromatog

Abstract:
Sagu (Maranta arundinacea), es una planta que se caracteriza por sus rizomas cilíndricos y tuberosos de los cuales se extrae almidón, sin embargo, poco se ha reportado sobre las bondades que pueden brindar sus hojas para la alimentación animal. Por tanto, el objetivo de esta investigación fue determinar la presencia o ausencia de metabolitos secundarios en hojas y rizomas de sagu y caracterizar la fibra de las hojas con el fin de determinar su valor nutricional. Se realizó a las hojas y rizomas de sagu, un análisis proximal (Materia seca (MS), proteína cruda (PC), extracto etéreo (EE), Cenizas

Abstract:
Objectives To determine endocrine factors that regulate the partitioning of amino acids by the mammary gland. To evaluate dietary flow and supply of energy and amino acids and their effects on milk protein synthesis and endocrine status. To use primary cultures of cow mammary epithelial cells to examine the role of specific factors on the rates and pattern of milk protein synthesis. Milk protein is an increasingly valuable component of milk but little is known regarding the specific hormonal and nutritional factors controlling milk protein synthesis.
