Ice Cream Composition

Below are the compositions of an ice cream
  • More than 10% milkfat and usually between 10% up to 16% fat in some premium ice creams
  • 9 to 12% milk solids-not-fat: this component, also known as the serum solids, which contains the proteins (caseins and whey proteins) and carbohydrates (lactose) found in milk
  • 12 to 16% sweeteners: usually a combination of sucrose and glucose-based corn syrup sweeteners
  • 0.2 to 0.5% stabilisers and emulsifiers
  • 55% to 64% water which comes from the milk or other ingredients.
These compositions are percentage by weight. Since ice cream can contain as much as half air by volume, these numbers may be reduced by as much as half if cited by volume. In terms of dietary considerations, The percentages by weight are more relevant. Even the low fat products have high caloric content: Ben and Jerry's No Fat Vanilla Fudge contains 150 calories per half cup due to its high sugar content.

Making of Ice Cream

1. Mix sugar, 1/2 cup of milk or half and flavoring in a bowl, then seal it in a quart-sized plastic bag.

2. Take roughly two quarts of ice, crushed if possible, and place it into the gallon-sized bag with rock salt. Usually, the gallon bag will half full with the ice and salt mixture
3. Place the sealed quart-sized bag with the ingredients into the gallon-sized bag. Make sure the bags stay sealed. Do not allow the contents to mix at any time. If the bags don't seal enough, use duct tape to seal the top of both bags to ensure they don't open during shaking.
4. Gently agitate, massage, and shake the bags for about fifteen to twenty minutes. In this amount of time the contents of the quart bag should start to turn into solid ice cream. It is important that you are mixing the contents of the inner bag, but you don’t want to be so aggressive that you burst the inner bag or cut it on the ice. Double-bagging should prevent this. If your hands get uncomfortably cold, use a towel or an old t-shirt to hold the bags as you massage them; they will be quite cold and might become slippery with accumulated condensation. Consider using gloves or massaging while holding onto the top seal if a towel or similar cloth is not available.
