foam stability

Foam stability and leak were determined over a 90 min. period.

A foam stability test was not conducted on the nine gallon formulation."

The company also disagreed with certain specifics, saying the report mischaracterized foam stability tests.

It is thought that particulate aids in foam stability via the following mechanisms:

Rumen foam stability in cows selected for low or high bloat susceptibility.

African sorghum beer is high in protein, which contributes to foam stability, giving it a milk-like head.

It has been demonstrated that unhopped beer has poor foam development and foam stability.

Mousses do not require long-lasting foam stability.

Foaming is related to protein solubility while foam stability is affected by denaturation according to Kinsella (1979).

The foams stability is usually expressed as the time required for 50% of the liquid to drain from foam (a 50% reduction in foam volume).

"Although laboratory foam stability tests cannot replicate field conditions perfectly, these data strongly suggest that the foam cement used at Macondo was unstable.

Appropriate foam stabilities are necessary for proper performance of the materials onto/into which AEA's or surfactants are applied.

A novel method using ethanol precipitation has been developed for producing a low ovomucoid egg white preparation that retained much of its whippability and foam stability characteristics.

There is no indication that Halliburton highlighted to BP the significance of the foam stability data or that BP personnel raised any questions about it.

Foaming percent and foam stability of the isolates were analyzed by adding a 6 g sample into the bowl of a Kitchen Aid Model 45A mixer with wire whip.

Samples of foam and rumen liquor from bloated and non-bloated cows fed freshly cut lucerne or red clover were analysed to determine differences that may account of foam stability.

A protein will always have certain stresses that it must over come, such as gravitational and mechanical, it is the proteins ability to stabilize foam against these stresses that determines the foams stability.

Using gas-sparging rigs developed at KAT, foaming tendency is measured in terms of volume or height of the foam column and foam stability in terms of its collapse time.

Lipid-binding proteins We have devised a protocol for improving protein foam stability utilising a lipid-binding protein from wheat (puroindoline) based on a fundamental understanding of the interactions between lipids and proteins at interfaces.

Isaacs, E.E., Effect of Residual Oil on Foam Stability, Poster, Presented at SPE Forum on Reservoir Conformance Enhancement - Polymer, Gels and Foams, Colorado, August 1988.

Epidemiological studies found that Dow had been adding cobalt sulfate to the beer for foam stability since July 1965 and that the concentration added in the Quebec city brewery was 10 times that of the same beer brewed in Montreal where there were no reported cases.

Protein degradation via a proteolytic rest plays many roles: production of free-amino nitrogen (FAN) for yeast nutrition, freeing of small proteins from larger proteins for foam stability in the finished product, and reduction of haze-causing proteins for easier filtration and increased beer clarity.
