Sweeteners 974<br />

Solubility at 37°C: 334 g/100 ml water.<br />

Cooling effect (150 g powder/50 ml water at 37°C): -22.<br />

Thermally stable: resistant to heat. No yellowing or browning at temperatures up to 180°C and up to 200 to 220°C under certain conditions.<br />

Chemically stable: resistant to acids and dilute alkalis.<br />

Due to the absence of aldehyde groups, does not undergo Maillard or Cannizzaro reactions; esterification of sorbitol by fatty acids produces compounds<br />

with surface-active properties useful in foods, cosmetics, textiles and metallurgy; etherification of sorbitol by ethylene or propylene oxides produces<br />

polyethers useful in the synthesis of rigid polyurethane foams; reaction of sorbitol with aldehydes and ketones produces acetals such as dibenzylidene<br />

sorbitol, used primarily as a nucleating agent in polyolefins production.<br />

Acts as a good chelating agent in alkaline media in the presence of certain metal ions such as aluminium, copper or iron. Particularly useful in chelating of<br />

alkaline-earth metal ions.<br />

Low heat of solution and high solubility provides a pleasant cool taste.<br />

Unfermentable by many microorganisms, particularly those actively involved in tooth decay.<br />

Commercially available 70% aqueous solution has a pH between 6 and 7.<br />

Addition of ethanol to an aqueous solution decreases solubility.<br />

Slightly soluble in: methanol, isopropanol, butanol, cyclohexanol, phenol, acetone, acetic acid, dimethylformamide, pyridine, acetamide solutions.<br />

Solubility decreases with increase in level of dissolved HGS.<br />

Higher density than other polyols at the same concentration.<br />

Higher viscosity than other polyols at the same concentration and temperature.<br />

Refractive index increases linearly with dry solids concentration.<br />

Boiling temperature increases with increase in concentration.<br />

Decrease in freezing point of aqueous solutions with an increase in concentration.<br />

Preserves protein fibres from denaturation during the freezing process, so useful as a cryoprotectant.<br />

When placed in humid environments will absorb some of the moisture.<br />

A fall in humidity levels will cause sorbitol to release some moisture to re-establish an equilibrium.<br />

Can be used as a stabiliser by compensating for significant humidity changes.<br />

Non-volatile, so is not affected by dry environments. Stabiliser content remains constant and permanent.<br />

Can be used as a conditioning agent in creams or pastes.<br />

Gives good product consistency and a high level of elasticity.<br />

Heat of fusion: 43 to 45 cal/g.<br />

High storage stability.<br />

May be stored at 20°C without lumping at up to 68% relative humidity.<br />

Has a dendritic surface and is readily compressible.
