6 FAQs about [Gel hardness and high storage modulus]

What is the storage modulus of a fluid gel sample?

The 2 % wt fluid gel sample measurement displays approximately 920 Pa as the highest storage modulus, whereas the storage modulus of the 1 % wt sample is lower with a value of about 370 Pa and the storage modulus for the 0.5 % wt exhibits the lowest value of about 130 Pa.

What is the storage modulus of cross-linked gels?

The storage modulus of cross-linked gels were determined via a DHR-1 rheometer (TA Instrument, USA), equipped with a parallel plate geometry (40 mm diameter and 1 mm gap) at 25 °C.

Is there a relationship between size of protein aggregates and storage modulus?

However, a negative relationship between the size of protein aggregates and the storage modulus of gels was observed, due to that more cross links were induced by glutaraldehyde when smaller protein particles were present in gel network. 1. Introduction Soy proteins are widely used as ingredients in food products because of its gelling properties.

What is storage modulus?

The storage modulus is a measure for the portion of the deformation energy introduced through the motor movement and elastically stored in the sample, which gathers information on the inner structure of three-dimensional network in gel system.
