Juice flow behaviour was analysed using a controlled shear stress rheometer coupled to a thermostatic bath (Thermo Electron Co., Haake RheoStress 1, Waltham, MA, USA) with coaxial cylinders (Z34 DIN) using sensor system set at 20 °C following the Igual et al., [22 (link)] methodology. A relax time of 900 s was selected for the sample before running the test. Shear rate, (γ; s−1), was increased from 0 to 150 s−1 in 20 step (fixed duration for each step 30 s) and shear stress σ (Pa), was recorded.

Flow curves were performed on fresh emulsions (24 h after treatment) at 20 °C with a controlled stress rheometer (Haake Rheo Stress 1, Thermo Electron Corporation, Karlsruhe, Germany). A concentric cylinders probe was used. Samples were loaded into the probe for 5 min before starting the test in order to reach equilibrium.
Flow curves were obtained in ascending and descending shear rates in the range of 0.1 and 100 s−1 for 60 s, respectively. Ostwald de Waele rheological model (Equation (2)) were fitted for descending curves, and the rheological parameters (K, n) were obtained. From the difference between the area under the ascendant and descendant curves, the hysteresis was calculated as indicative of thixotropic behavior.

where s is the shear stress (Pa), K is the consistency index (Pa.sn), g is the shear rate s−1, and n is the flow behavior index (n = 1 indicates Newtonian behavior n ≠ 0 indicates non-Newtonian behavior).

Mechanical and Rheological Characterization of Yoghurt

The mechanical characterization of the yoghurt samples was carried out by means of a Texture Analyser (TA.XT Plus, Stable Micro Systems, Surrey, UK) equipped with a 50 kg load cell. A plunger with a diameter of 35 mm was used at a speed of 120 mm min -1 . The yoghurt samples were held in a plastic cup and placed on a flat holding plate at 12±1ºC. A maximum sample strain of 50% was employed. Firmness (N) (the maximum force reached during the compression cycle) and the adhesiveness (N*s) (negative force area) were calculated from the resulting curve. Ten replicates of each analysis were carried out for each condition and storage time.
The rheological behavior of the samples was determined at 12±1ºC using a controlled shear stress rheometer with a coaxial cylinders (Z34 DIN) sensor system coupled to a thermostatic bath (Thermo Electron Co., Haake RheoStress 1, Germany). A relax time of 300 s was chosen for the sample before running the test. The shear rate, γ&(s -1 ), was increased from 0 to 150 s -1 (duration step 300 s) and shear stress, σ (Pa), was recorded.
Four tests were carried out for each yoghurt sample. For each sample, the mean value of apparent viscosity (Pa*s) was reported at 100 s-1.

Rheological properties of FB-PεCL-NPs suspension were evaluated at 25°C using a rotational rheometer HAAKE RheoStress 1 (Thermo Fisher Scientific, Waltham, MA, USA) equipped with a fixed lower plate and an upper cone plate, 2° (Haake C60/2° Ti, 6 cm diameter). Viscosity curves and flow curves were recorded for 3 minutes during the ramp-up period from 0 seconds−1 to 100 seconds−1, 1 minute at 100 seconds−1 (constant share rate period), and finally, 3 minutes during the ramp-down period from 100 seconds−1 to 0 seconds−1. All measurements were performed in triplicate.

Rheological Characterization of Cookie Dough

Rheological behaviour of the fresh cookie dough was evaluated using a rheometer (Haake RheoStress 1, Thermo Fisher Scientific, Scheverte, Germany). Each dough sample was placed on a titanium parallel-serrated plate geometry PP60 Ti (60 mm diameter, 3 mm gap) and covered with Panreac Vaseline oil (Panreac Química S.A., Castellar del Vallés, Spain) to avoid drying during the test. A Phoenix II P1-C25P water bath maintained the temperature at 25 °C.
In the first measurement, the cookie dough was subjected to a strain sweep (stress range of 0.1–100 Pa) at a constant temperature (25 °C) and frequency (1 Hz) to identify the linear viscoelastic region. Then, using these results, a stress value within the linear viscoelastic region was selected and applied in a frequency sweep test to obtain the values of the elastic modulus (G’, Pa), viscous modulus (G”, Pa), complex modulus (G*) and tan delta (G”/G’) over a range of frequency values (w, Hz). The measurements were made in duplicate.

Example 18

Dynamic light scattering (DLS) was performed using a Malvern Nano Zetasizer ZS (Malvern Instruments Ltd Enigma Business Park, Grovewood Road, Malvern, Worcestershire, UK. WR14 1XZ) and a Haake Rheostress 1 (Thermo Fisher Scientific, Karlsruhe, Germany) equipped with a cone with 60 mm diameter/0.5° angle for buffer viscosity measurements.

All samples were centrifuged (Centrifuge 5415C, Eppendorf, Vienna, Austria) for 5 min at 10.000 rpm to determine the hydrodynamic diameter of a protein. 60 μL of sample were filled into a ZEN0040 disposable micro cuvette and viscosity of buffer was determined by Rheostress 1. This parameter is used for analyzing effective size of proteins by DLS. Operation temperature was 25° C. with an equilibration time of 2 minutes. The proteins angle was set to 173° backscatter to measure the size of and 3 runs per sample were performed to average the results.

Samples were measured by increasing temperature mode to monitor the influence of temperature on a protein. Measurement procedure was similar to a normal size measurement, except for different temperatures with an increasing value of 1° C./min from 15° C. to 80° C. and an equilibration time of 2 min. A DTS2145 low volume glass cuvette was used for these temperature ramps.

Rheological Analysis of Hydrogel Gelation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The gelation process of
the hydrogels has been analyzed by means of linear oscillatory rheology
using a control stress HAAKE RheoStress 1 (Thermo Fisher Scientific,
Waltham, MA, US). The rheometer was connected to an external thermostatic
bath. The measurements were carried out using a cone–plate
sensor with a 35 mm radius and 1° angle. Once the hydrogel was
prepared, it was placed in the lower plate at 20 °C. Then the
upper cone was lowered to the measurement position, and the temperature
is gradually raised to 37 °C. Once the sample has been equilibrated
at this temperature, the hydrogel gelation was analyzed by applying
a very low stress of γ = 0.45 Pa at a frequency of 0.1 Hz with
a cyclic strain of 0.5% amplitude, which guarantees a torque of 5
μNm and a linear viscoelastic regime. To mitigate the evaporation
of water from the hydrogel, a liquid trap was used. Storage moduli
(G′) were recorded as a function of time using
HAAKE Rheowin software (Job and Data Manager). Three samples were
used for each test condition.

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.
