The solid substrate silica gel (mesh size 70-230, of surface area 300m3/g) and sodium nitrite (NaNO2
) were obtained from LobalCheme (Gujarat, India), silylation coupler (p-Aminophenoxy)propyltrimethoxysilane was purchased from Fluorochem Ltd.(Hadfield, UK).
An aliquot (0.25 ml) of test samples solution in ethanol and water were mixed with 1.25mL of distilled water and 75 uL of 5% sodium nitrite (NaNO2
Dry ingredients (NaCl, sodium phosphate, sodium erythorbate, black pepper, red pepper, oregano, garlic and onion powder, monosodium glutamate and NaNO2
) (BRC Ingredients, Rio Claro, Brazil) were added to the raw meat and mixed manually for 2min.
Indeed, at pH 6.0 and 10[degrees]C, the inhibitory effect of nitrite is minimal after adding 400 ppm NaNO2
. Therefore, microbiological safety of processed meat products with lower nitrite levels can be improved by a combination of pH and sodium chloride concentration.
Trying to cut ammonia discharge levels and energy costs at the Nokomis Waste Water Treatment plant through another NanO2

, NaOH, and Al [(NO3)3 were analytical grade and acquired from Shanghai Macklin Biochemical Co., Ltd.
As far as nanoparticle size, morphology, and probable emulgator remaining from abovementioned results, preparative parameters of Nano2
as an optimal condition for W/O/W technique were chosen for further investigation.
The derivatization reagents of sodium nitrite (NaNO2
) and hydrochloric acid (HCl) were purchased from Henan Jiaozuo Three Chemical Plant (Jiaozuo, China) and Shijiazhuang Reagent Factory (Shijiazhuang, China), respectively.
To each concentration of the quercetin (0.5 mL), deionized water (2.0 mL) was added followed by NaNO2
(5%w/v, 0.15 mL).
The reagents used for the synthesis of diazonium chloride, including p-phenylenediamine, sodium nitrite (NaNO2
), concentrated hydrochloric acid (HCl), and iron powder were purchased from J&K Scientific Ltd.
Additionally, to generate 0.75 mM mM of CysNO contained MS medium, different concentration of CysNO stock solutions (125 mM, 250 mM, and 500 mM) were prepared by mixing equal amounts of L-cysteine solution and NaNO2
