Traditionally ice-cream was categorised as super-premium, premium, standard or economy. These ice-creams usually vary by fat content, total solids, overrun, flavours, packaging and cost (Tharp & Young 2013a, Goff 2010) as shown in the table below. As there are no legal guidelines of different ice-cream categories, this is just a guide and may differ from industry to industry.
|Fat||10% (depending on legal requirements)||10% – 12%||12% – 15%||15% -18%|
|Total solids||30% (depending on legal requirements)||36% – 38%||38% – 40%||>40%|
|Overrun||Legal maximum.||100% – 120%||60% – 90%||25% – 50%|
|Cost||Low||Average||Higher than average||High|
|Packaging and graphics||Basic. usually available in large quantities. The word ‘economy’ is rarely used and is usually identified by the price||The word ‘standard’ is not usually shown on the packaging. Also available in large quantities.||The word ‘premium’ is used on the packaging. Usually available in smaller packs than economy & standard.||Individual pots are common in this category.|
|Additional notes||Artificial colours and flavours are widely used and usually the flavours are standard||Typically the flavours are standard.||Uses ingredients perceived to be natural. Novel flavours and additions are very common||Uses high quality ingredients. Novel flavours and additions are very common|
A new category of ice-cream is emerging known as ‘Premium Light’ ice-cream (Tharp & Young 2013b). This is an ice-cream which provides the eating quality of premium ice-cream but with lower fat. Some manufacturers market these directly as premium light ice-creams, whilst others use it just for cost savings.
These can be made by altering the recipe or the procedure.
To alter the procedure, a refrigerated twin screw extruder attached to the ice-cream freezer is required. As the ice-cream is passed from the freezer into the extruder, the freezing process continues. This results in lower ice-crystal sizes and the ‘churned’ process also results in an increase in perceived creaminess (Tharp & Young 2013b).
To alter the recipe, some of the milk fat is replaced with a fat replacer. CyberColloids has completed extensive work in this area and should you require further information on fat replacers for your low fat or premium light ice-cream please contact us.
