Exploring the chemical composition of granola formulated with different sweeteners and produced via oven and microwave baking.

The objective of this study was to create and characterize an innovative granola, a popular choice in quick breakfasts. The granola samples were sweetened with agave syrup (A), honey (H), and stevia (S) and produced using conventional oven (1) and microwave (2) baking techniques at temperatures of 160°C and 300 W, respectively. Among the samples, H1 exhibited the highest total sugar content (26.

Classification of buckwheat honey produced in Kazakhstan according to their biochemical ingredients and bioactivities by chemometric approach.

Herein, nineteen buckwheat honey samples collected from 19 stations of different ecological zones of Kazakhstan were analysed for their pollen density, physicochemical properties, chemical composition, antioxidant, anticholinesterase, tyrosinase inhibitory, and urease inhibitory activities with chemometric approaches. Twelve phenolic compounds and fumaric acid were identified using HPLC-DAD, and mainly fumaric, p-hydroxybenzoic, p-coumaric, trans-2-hydroxy cinnamic acids, and chrysin were detected in all samples. The honey samples collected from the Northern zone exhibited best antioxidant activity in lipid peroxidation inhibitory (IC:8.

Intercalation of pyrazolone-based oxalamide metal complexes into Na-montmorillonite for catalytic liquid-phase oxidation of phenol using HO.

The intercalation of pyrazolone-based oxalamide metal complexes into Na-montmorillonite (Na-MMT) for catalytic liquid-phase oxidation of phenol using HO was undertaken by a flexible ligand method using metal ions including Mn(II), Zn(II), and Sn(II). First, the metal ions were exchanged with the sodium ions of Na-MMT, and then these metal ions were complexed with a new pyrazolone-based oxalamide ligand. The intercalated metal complexes were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, elemental analysis, and thermogravimetric analysis.

Use of Hydrogen-Rich water in rice milk preparation improves the nutritional and sensory properties of product.

The effect of using hydrogen-rich water (HRW) in the preparation of rice milk on the nutritional and sensorial properties was evaluated. The physicochemical parameters (pH, Eh7, titratable acidity), sensory properties (color), and minerals (ICP-MS), as well as amino acid (UPLC-ESI-MS/MS), sugar (HPLC-RID), and aroma (SPME-GC/MS) profiles, of four varieties of rice and their milk and waste were examined using Principal Component Analysis (PCA). Results showed that the profile of minerals, sugars, amino acids, and aroma was affected by the use of HRW.

Assessment of physicochemical parameters, bioactive compounds, biological activities, and nutritional value of the most two commercialized pollen types of date palm ( L.) in Morocco.

The pollen of date palm ( L.) is known for its nutritional value and implications as a health-promoting component. Due to its low cost, date palm pollen crushed with its spadix is more widely commercialized and used in Morocco than pure date palm pollen free of spadix.

Determination of water content in dimethyl sulfoxide/N,N-dimethyl formamide and methanol content in ethanol by solvatochromism of azo dye, 2-(tert-butyl)-4-methoxy-6-(naphthalen-1-yldiazenyl) phenol.

A novel 2-(tert-butyl)-4-methoxy-6-(naphthalen-1-yldiazenyl)phenol (NAP) was synthesized by coupling reaction of 2-tert-butyl-4-methoxyphenol with diazotized naphthylamine as diazo component. The azo dye was characterized by NMR, FT-IR and UV-vis spectroscopic techniques. The visible spectrum of NAP was recorded in different solvents and at different pHs.

A novel approach to redox active polymers: Decolorization of methylene blue by heterogeneous reduction with redox active azo polymer.

The existing reducing agents used in the literature to decolorization of methylene blue are soluble in water and the reduction process is carried out in a homogeneous redox reaction medium. After the decolorization process, the reducing agents and its by-products remain in a homogeneous redox reaction medium. Many of these reducing agents are toxic and cause chemical pollution of textile wastewater.
