*2.7. Rheological Behavior*

The viscosity of dispersion of the samples was determined using an ARES-G2 rheometer (TA instrument, New Castle, DE, USA) with DIN geometry (diameter 27.77 mm, gap 5.849 mm) with a cup (diameter 29.9 mm). Briefly, 0.75 g of sample (insect meals and hydrolysates) was dispersed at 3% (*w*/*v*) in McIlvaine buffer (pH 4.0, 5.5 and 7.0) in a centrifuge tube and stirred for 30 s. The dispersion was stored at 4 ◦C for 12 h and stirred again for 30 s. The dispersion was then conditioned at 23 ◦C and a pre-shear at 10 s−<sup>1</sup> for 60 s was applied. The flow experiment was performed by increasing the shear rate from 10 to 750 s−<sup>1</sup> . Data were analyzed using TRIOS software (TA Instrument). The flow properties were determined by fitting the data to the Power Law Model on the flow sweep for a shear rate from 10 to 100 s−<sup>1</sup> . Equation (3) describes the Power Law Model:

$$
\sigma = k \dot{y}^n \tag{3}
$$

where σ is the stress (Pa), *k* is the viscosity (Pa·s), *y* is the shear rate (s−<sup>1</sup> ) and *n* is the flow behavior, allowing fluids classification: pseudoplastic (*n* < 1), dilatant (*n* > 1) and Newtonian (*n* = 1).
