The aim of this study was to determine correlations between the concentration thiamine hydrochloride or pyrophosphate and antioxidant activity epigallocatechin gallate (EGCG) caffeine, as well stability. conducted in model systems. Oxidation degree indices soybean oil (peroxide value anisidine LAN) concentrations total were determined. To compare dynamics changes content during storage, half-li...

The preparation of flavored vegetable oils using spice and herb plants is considered to be an indispensable opportunity for the application these plants. In present exploration, sunflower oil (SFO) samples by Mentha spicata L. (spearmint) were prepared maceration method (MM) ultrasound-assisted (UM). antioxidant effects, sensory evaluation oxidative stability during accelerated storage; physico...

Synthesis of the title compound from 4-methoxyaniline was accomplished in three steps. The structure was supported by spectroscopic data and unambiguously confirmed by single crystal X-ray diffraction data. It crystallizes in the monoclinic space group P21 with unit cell dimensions a = 9.9349(8), b = 6.3377(5), c = 10.5783(10) Å, β = 97.752(3)°, V = 659.97(10) Å, Z = 2.

in this work, poly (o-anisidine) (poa) was prepared by consecutive potential cycling in an acidic monomer solution at the surface of carbon paste electrode (cpe). nickel ions were dispersed into the polymer by immersing the electrode in niso4 solution. the prepared ni/poa/cpe was characterized by scanning electron microscopy, energy dispersive x-ray spectroscopy, atomic force microscopy (afm) a...

In order to optimize the screw-press extraction conditions of oil from goldenberry (Physalis peruviana L.) seeds obtained nectar processing waste, a face centered design was applied. The extracted at different temperatures (60, 80, and 100°C) seed moisture contents (8, 10, 12%). Oil recovery (OR) increased residual in cake decreased significantly as content temperature were reduced; volatile ma...
