} catch(err) { function(){ } Elasticity is defined by the ability of a material to return to its original shape after it is deformed. if (i.toString() == parts[0]){

Freeze-thaw stability should not be confused with thermoirreversibility.

i = parseInt(parts[0]); For example, neither locust bean gum nor xanthan gum form gels alone, but will form a gel when you combine the two hydrocolloids.

The change in properties (such as viscosity, elasticity, and cluster-size distribution) near the point of gelation obey the predictions of percolation theory 7, 12, 13. this.value = ''; As a chef, there are two types of properties to consider when choosing a gelling agent: aesthetic and functional. } script.src = 'http://downloads.mailchimp.com/js/jquery.form-n-validate.js'; For gels, the modulus increases in proportion to the volume fraction of solids to a power between ∼3 and 4; consequently, the evolution of the modulus during drying and the final shrinkage can be estimated.

A gel is a bicontinuous liquid-solid system of colloidal dimensions; that is, one can move from the solid into the liquid, or conversely, without moving as far as a micron. High-fat gels and starches tend to have a slow and long-lasting flavor release while gelatins, pectins and gellan gels tend to have a fast and short-lived flavor release. } Email once or twice a month.

Once the gelatin liquid has been heated, it forms a gel at refrigerator temperatures.

} else if ( fields[0].value=='' && fields[1].value=='' && (fields[2].value=='' || (bday && fields[2].value==1970) ) ){ Under static conditions, these hydrocolloids produce solid gels (or thick viscous fluids) that will start flowing and become less viscous when agitated, stirred, shaken or blended. The gel begins to melt at the upper range of reasonable room temperature. $('#mce_tmp_error_msg').remove(); When blending an agar agar gel, it breaks down into tiny pieces but will not revert back into a solid. $('#mc-embedded-subscribe-form').ajaxForm(options); All gels have a temperature at which they will gel and melt.

$(f).append(html); While there are inelastic materials that have a brittleness independent of their elasticity (like metals, for example), edible gels are almost all elastic, so you can think of elasticity and brittleness as opposites when dealing with edible gels.

When we think of solids and liquids, we think of a static temperature at which a solid turns into a liquid and vice versa. },
