The overrun of a Dairy ice-cream, Ice-cream, Frozen dairy dessert, Frozen dessert, Frozen yoghurt, Frozen yoghurt and Dairy ice-cream blend, Frozen yoghurt and Ice-cream blend and Frozen fruit sorbet sample shall be determined at the factory by using one of the following methods: Provided that inclusions shall not be taken into account:
| A. |
Calculation by volume: |
The overrun is calculated by using the following formula :
| B. |
Use of an overrun cup and overrun table: |
| (1) |
The overrun is determined as follows by means of an overrun cup: |
| (a) |
Place a clean, dry overrun cup on a scale and adjust the scale to zero. |
| (b) |
Fill the overrun cup completely with Dairy ice-cream mix, Ice-cream mix, Frozen dairy dessert mix, Frozen dessert mix, unfrozen Yoghurt, a blend of unfrozen Yoghurt and Dairy ice-cream mix, a blend of unfrozen Yoghurt and ice-cream mix or unfrozen Fruit sorbet, as the case may be. |
| (c) |
Weigh the overrun cup and its contents and record the mass. |
| (d) |
Clean the overrun cup thoroughly and dry it. |
| (e) |
Slightly overfill the overrun cup with aerated Dairy ice-cream, Ice-cream, Frozen dairy dessert, Frozen dessert, Frozen yoghurt, Frozen yoghurt and Dairy ice-cream blend, Frozen yoghurt and Ice-cream blend or Frozen fruit sorbet, as the case may be. |
| (f) |
Remove all inclusions (e.g. chocolate coating, pieces of chocolate, fruit, nuts, etc.) where possible, and ensure that no air pockets are trapped in the cup. |
| (g) |
Level the sample in the overrun cup off with the surface of the cup. |
| (h) |
Weigh the overrun cup and its contents and record the mass. |
| (i) |
Calculate the overrun by using the following formula: |
| (j) |
The overrun can also be determined by using an overrun table as supplied by the factory and which is based on the specific gravity value (SG) of the product concerned: Provided that the specific gravity value (SG) of the product concerned shall be provided by the factory on request from the inspector. |
| (2) |
In the case of Dairy ice-cream, Ice-cream, Frozen dairy dessert, Frozen dessert, Frozen yoghurt, Frozen yoghurt and Dairy ice-cream blend, Frozen yoghurt and Ice-cream blend or Frozen fruit sorbet packed in smaller units, the volume can be determined as follows by the displacement of water: |
| (a) |
Weigh the sample and its container and record the mass. |
| (b) |
Remove the sample from its container. |
| (c) |
Weigh the empty container and record the mass. |
| (d) |
Place a known volume of water into a measuring beaker. |
| (e) |
Submerge the sample in the water and record how much water is displaced. |
| (f) |
Calculate the overrun by using the following formula: |
V = The volume of water displaced by the sample
M = The mass of the sample after subtracting the mass of the container
