3.8 Counterions Counterions are also known as spectator ions. There are always present, because they are necessary to balance the overall charge of a solution Full reaction with couterion included: Reaction without counterion even though it is present Why are they often left out of a reaction?
Greater free radical scavenging activity indicated the lesser absorbance of the reaction solution. The 1 mL DPPH solution was added to methanol (3 mL) and the absorbance was taken as a blank. The DPPH radical scavenging activity was evaluated using the equation given below. DPPH radical ...
The reaction depends on the ability of the samples to scavenge free radicals, which can be visually observed by its color change from purple to yellow due to its hydrogen donating ability [25]. The shorter the time taken for the absorbance to reduce, the stronger the antioxidant activity of ...
for 15 min. Then, 0.5 mL of 1% starch solution was added. After 10 min, the reaction was stopped by adding 1 mL of 3,5-dinitrosalicylic acid and heating for 10 min. The mixture was then made up to 10 mL with distilled water and the absorbance was measured at 415 nm against a ...
Absorbance (A) was measured at the initiation of the reaction, then after 10 and 20 min. The antioxidant activity was calculated using the formula: %RSA = (ADPPH − Asample)/ADPPH ×100 [65,66]. 4.4. Antifungal Activity 4.4.1. Micro-Organisms and Culture Conditions To test the ...
To evaluate these variables in MSL extracts, the DPPH• radical assay and a method based on the Folin–Ciocâlteu reagent reaction were selected, as they are analytical procedures that are commonly used in phytochemical studies and allow for a comparison of the results obtained by different ...
Different cooking methods (grilling, roasting and boiling) develop different kinds of flavour in lamb meat due to a reaction between amino acids and sugars as well as lipid degradation. This occurs at a temperature between 150 and 250 °C, and further denaturation of proteins on the surface of...
