    Abstract: The invention is a depositing device for depositing flowable food containing gas comprising a pressurized feed N line conveying flowable food containing gas under pressure into the food; piston means operatively connected to the feed line comprising a piston and a chamber; an outlet to deliver food at the atmospheric pressure into molds. The device comprises a pressure retaining means arranged to retain the product in the chamber at the same pressure as the line pressure and to deliver the product through the outlet as pressure in the chamber increases from the line pressure upon descent of the piston in the chamber.
