The pH was measured at 22 °C with a properly calibrated pH glass electrode (Crison Instruments, S. A., Barcelona, Spain) by directly submerging the probe into the homogenized kefir samples.
Titratable acidity was quantified according to Chandan et al. (2006) [21 ], with some modifications, by titrating of 12 mL of diluted kefir to pH = 8.9 with a 0.1 N NaOH solution (Merck KGaA, Darmstadt, Germany) using an automatic titrator (Titromatic 1S, Crison Instruments, S.A., Barcelona, Spain). The results were expressed in milligrams of lactic acid/g of kefir.

Colorimetric Titration for Acid Content

Check if the same lab product or an alternative is used in the 5 most similar protocols

Acid contents of samples were determined by colorimetric titration method. 10 g of the samples were taken and completed to 100 ml. After filtration, 10 ml of the filtrate was titrated with 0.1 N NaOH solution (Merck, Germany) up to the color changing point of phenolphthalein indicator. Acidity values were calculated from the spent NaOH (Anonymous,1995) .
V: volume of the 0.1 N NaOH solution spent in the titration (ml) N: normality E: equivalent acid m: sample weight (g)

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
