Hardpack frozen desserts providing a carbonation sensation even after frozen storage over an extended shelf life, and methods of making such hardpack frozen desserts are described. Hardpack frozen desserts have a particular solute content, providing a solute molarity of at least 1.0 molar, and/or a solute molality of at least 0.78 molal, and/or an Aw of the mixture of 0.91 or less.

A process for the manufacture of frozen gas hydrates, the process comprising passing a liquid aqueous phase over a heat exchanger surface under an atmosphere of a pressurised water-soluble gas, characterised in that the conditions of the process are selected to ensure that there is simultaneous dissolution of the pressurised gas into the liquid aqueous phase, and the formation of a solidified continuous phase from solidification of the liquid aqueous phase in contact with the heat exchanger surface.

A device for emulsifying liquid or solid products, in particular food products such as milk or ice cream, including a pump having at least one suction duct adapted for sucking a product to be emulsified and an emulsifying gas, and a delivery duct adapted for dispensing an emulsion obtained starting from the product to be emulsified and from the emulsifying gas, where the pump has a double worm screw arranged between the suction duct and the delivery duct, the double worm screw being adapted for emulsifying the product and the gas to obtain the emulsion and to push the product, the gas and/or the emulsion with a flow substantially parallel to the axis of the screws of the double worm screw from the suction duct to the delivery duct. Moreover, the device comprises cooling means associated with the pump in an area comprised between the suction duct and the delivery duct and adapted for cooling the product, the gas and/or the emulsion present in the area of the pump comprised between the suction duct and the delivery duct.

The invention relates to a foamable or whippable food composition, in particular a cream, comprising at least 12 wt. % fat, protein, water, a citric acid ester of a mono- or diglyceride of one or more fatty acids comprising an unsaturated acyl chain and a lactic acid ester of a mono- or diglyceride of one or more fatty acids, the total content of substances other than water being at least 15 wt. % of the total weight of the composition.

An apparatus (300) for aerating a food product, (200, 300) comprising a housing (10) with an inlet (100) for the food product and an outlet for the aerated food product, and, within the housing (10), first and second pairs (210, 220, 240) of a rotor and a stator each having complementary toothed rims orientated in opposition in the axial direction, and a gas injector (1) for injecting, at an upstream position relative to the first pair (210, 220) of a rotor and a stator, a gas in the food product to be aerated, wherein a further inlet (310) is provided for injecting, at a position between a pair (210, 220) and an adjacent pair (240) of a rotor and a stator, an additional composition to be mixed with the food product.

The invention relates to apparatus and method of making a frozen confectionary product such as ice cream or sorbet in which a confectionary mix is churned in a vessel whilst a liquid gas such as liquid nitrogen is added. Existing churning apparatus moves a stirrer through the ice cream mix in an epicyclical motion. This tends to splash liquid nitrogen so that it evaporates without contributing to the freezing of the ice cream. In the improved mixing method, the stirrer is repeatedly drawn against the inside wall(s) of the vessel. This reduces splashing of the liquid nitrogen. The drawing action also removes build up of frozen confectionary product on both the stirrer and the vessel walls and allows unfrozen confectionary mix to move to the edges of the vessel and be preferentially frozen.
