![]() ![]() Nitrous oxide is bacteriostatic (it inhibits bacteria growth), so a charged cream dispenser can be kept in the refrigerator for up to two weeks. The change in pressure causes some of the dissolved gas to return to bubbles, effectively fluffing up the cream. When the cream dispenser's valve is opened, the cream solution is expelled by the high pressure inside. In a sealed container, this cream is pressurized with nitrous oxide, which dissolves into the cream as per its lipophilicity. The recipe for the cream to be whipped typically calls for heavy cream and sugar, along with any desired flavorings or colorings. The cream must have a minimum fat content of 28% to produce whipped cream with a dispenser. Nitrous oxide is used because it dissolves easily into the cream, and does not cause the cream to oxidize while it is in the can. Uses Culinary Whipped cream from a nitrous oxide dispenser, on a slice of pumpkin pie These are desirable if the volume is more than a production level of ten litres per hour. Whipped cream chargers are intended for low-volume or occasional use, such as home kitchens, restaurants, and coffee shop applications.įor very high volume commercial use, there are regulated tank systems for filling much larger containers and dispensing more whipped cream. Their standard capacity is 7.8 grams of nitrous oxide. In Europe, where the production and use of whip cream chargers originated, there are presently three factories involved in its production. While refillable chargers were once available, all chargers are now non-refillable the latter consist entirely of recyclable steel. Their walls are about 2 millimetres ( 1⁄ 16 in) thick to withstand the pressure of the gas, and they are rounded at one end with a narrow tip at the other end. The cylinders are about 6.3 centimetres ( 2 + 1⁄ 2 in) long by 1.8 cm ( 3⁄ 4 in) wide, with a volume of 10 cubic centimetres (0.6 cu in) and capacity for most brands of 8 grams ( 1⁄ 4 oz) of pressurized N 2O. The kitchen appliance that receives the charger is a whipping siphon.ĭescription A box of chargers, showing their foil sealed ends that release the gas after being punctured. Among users, the chargers are colloquially called whippets, nos, nossies, or nangs. ![]() Nitrous oxide is a popular recreational drug, and whipped cream chargers are a convenient source of the gas. ![]() The nitrous oxide in chargers is also used as an oxidizer in hybrid model rocket engines. This is usually done by a sharp pin inside the whipped cream dispenser. ![]() The narrow end of a charger has a foil covering that is broken to release the gas.
