800 w blender

A sample of the meat product of 10 g in weight was mixed with 50 cm 3 of distilled water and homogenized using an 800 W blender (Bosch, Munich, Germany) for 1 minute at a speed equal to 14,000 RPM. In such a solution, the measurements were carried out, using a Delta 350 pH meter (Mettler Toledo, Schwerzenbach, Switzerland), with the application of an electrode In Lab Redox Pro (Mettler Toledo, Greifensee, Switzerland). The result was read after its stabilization. The measurement was conducted at a temperature of 20°C ± 2°C. The obtained result of the measurement (mV) was calculated into the value of redox potential in relation to the standard hydrogen electrode E H (mv). To this end, the value of the potential of the reference electrode at a temperature of 20°C-E ref = 210 mV was added to the readout value which was obtained with the equipment.

The pH value of the meat products was determined according to PN-ISO 2917:2001. A test sample of 10 g weight was mixed with 50 cm 3 of distilled water and homogenized using an 800 W blender (Bosch, Munich, Germany) for 1 minute at a speed equal to 14,000 RPM. Measurement of the pH of the homogenates was performed using a Delta 350 pH meter (Mettler Toledo, Schwerzenbach, Switzerland) with an automatic compensation temperature, using a glass-calomel electrode In Lab Cool (Mettler Toledo, Greifensee, Switzerland).
