A packaged food article of improved appearance and stackability comprises an unpressurized, imperforate container having an opening, wherein the container is fabricated from a material having a low gas permeability. A quantity of gas releasing food stuff, such as an active cultured dairy product, is disposed within and partially fills the container, while defining a headspace volume which is not filled with the food stuff A peelable flexible seal membrane overlays and seals the opening. An initial headspace gas is enriched with the gas released from the food stuff, with the initial headspace gas being adapted to permeate the packaging material at a rate greater than both the rate in which gas is released from the food stuff within the container and the rate in which air permeates into the container, thereby avoiding outward bowing of the flexible seal during the shelf life of the packaged food article.

Packaged food articles with enriched headspace

Packaged food articles of improved appearance and stackability are described such as a refrigerated active cultured dairy product. Each packaged food article comprises an unpressurized, imperforate container having an opening, wherein the container is fabricated from a material having a low gas permeability. A quantity of gas releasing food stuff, such as a live cultured dairy product, is disposed within and partially fills the container defining a headspace volume which is not filled with the food stuff. A peelable flexible seal membrane overlays and seals the opening. An initial headspace gas is enriched with the gas released from the food stuff, with the initial headspace gas being adapted to permeate the packaging material at a rate greater than both the rate in which gas is released from the food stuff within the container and the rate in which air permeates into the container, thereby avoiding outward bowing of the flexible seal during the shelf life of the packaged food article.

Method of preparing packaged food articles

Nutritionally improved cultured dairy products, such as milk beverages and yogurt products, include a fine powdered calcium phosphate salt of reduced particle size having a mean diameter &lE;6&mgr;m in amounts sufficient to provide a total calcium content of 0.25% to 0.75%. A method for producing the calcium fortified products is also provided wherein an fine powdered insoluble calcium salt is admixed with a milk blend prior to fermentation. A yogurt can then be prepared by conventional fermentation. Both stirred style and cup set style yogurt products can be prepared.

Calcium fortified products and methods of preparation

Refrigerated cultured dairy products such as yogurt having enhanced anti-mold stability are prepared by including minute quantities of a cultured dairy ingredient having been cultured with a propionic acid forming culture. The propionic bearing cultured dairy ingredient such as whey is added to a milk base that is then heat treated prior to inoculation and fermentation with a yogurt culture. Premature protein coagulation that can occur during the heat treatment step is minimized by adding minute quantities of a calcium sequestrant to the milk base.
