ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to packaged food articles and to their methods of preparation. More particularly, the present invention relates to articles comprising a gas-impermeable container and a flour based batter for brownies that are storage stable at room temperature.
BACKGROUND
Baked goods such as brownies are popular consumer snack food and dessert food items. Traditional brownies are a particularly delectable baked dessert. A wide variety of recipes are currently available for use by consumers to prepare small quantities of brownies from various ingredients.
For greater convenience and shelf stability, dry mixes for brownies have long been available. The consumer mixes the dry mix with liquid ingredients such as water, oil, milk and/or eggs to form a batter. The batter is then immediately poured into a baking pan and baked to form the finished baked goods. Useful developments in the formulation of dry mixes for brownies continue to be made. For example, an improved dry mix for brownies is disclosed in U.S. Ser. No. 08/929,827 filed Sep. 15, 1997 by Palmer et al entitled “Dry Mix for Baked Goods with Gellan Gum and Method of Preparation” (which is incorporated herein by reference). The dry mixes for brownies disclosed therein include gellan gum in addition to other ingredients. The dry mixes not only are useful for preparing, high quality finished baked goods by consumers for home use, but also can be used for the large scale production of finished baked goods suitable for refrigerated sales and distribution. While the formulation for the dry mix is improved, the dry mixes are packaged in a conventional manner in a sealed bag placed in a conventional carton or in pouches without the carton.
While dry mixes for home use are convenient, current trends for consumer package food products favor products of even greater convenience. The present invention provides improved products of greater convenience. The present invention provides articles comprising ready-to-bake batters that are shelf stable at room temperatures.
Refrigerated ready-to-bake batters having relatively short shelf lives are also known. One problem with such products concern is bacterial growth. A second problem resides in providing a leavening system that retains functionality over extended storage. Acidifying the batter desirably extends bacterial stability but the acidity undesirably tends to interact with the leavening system, and leaves an undesirable acid aftertaste. With poor leavening, the finished baked goods exhibit undesirable volume and poor texture. The present invention provides ready-to-bake batters for brownies articles that are shelf stable even at room temperature.
The present articles thus provide the benefits combination of shelf stability of conventional dry mixes with the greater convenience of ready-to-bake batters.
The present invention resides in part in the surprising discovery that CO
2
gas producing leavening agent is not an essential ingredient in the present packaged ready-to-bake batters.
Shelf stable batters for layer cake articles are commercially available, for example, in France made as described in EP 868,850 A published Oct. 7, 1998. Such articles comprise an impermeable flexible membrane pouch containing a batter comprising a CO
2
gas producing leavening system and an inert gas atmosphere.
SUMMARY OF THE INVENTION
In its product aspect, the present invention resides in ready-to-bake batter articles that provide improved finished baked goods, especially brownies. The articles comprise an unpressurized gas impermeable container, a high pH, low water activity, high sugar to flour ratio brownie batter disposed within the container and an inert low oxygen gas in the headspace not filled by the batter.
The sugar to flour ratio ranges from 1.5:1 to about 3.5:1 The water activity is less than 0.85 the pH ranges from about 6.0 to 8.5. The brownie batter can be aerated with sufficient amounts of N
2
O to provide the batter with a density of about 1.00 to 1.2 g/cc. The brownie batter can be aerated with other inert gases such as Nitrogen or Carbon Dioxide. In some cases, no aeration is used. The batter can also be made with or without any chemical leavening system. The headspace inert gas has an oxygen content of less than 4%, preferably less than 2%.
In its process aspect, the present invention is directed to processes for making a ready-to-bake batter article that is shelf stable at room temperature. The process comprising the steps of:
providing an open sealable, gas impermeable container;
dispensing a brownie batter within at least a portion of the container, said brownies comprising:
about 25 to 70% sugar,
About 10 to 40% flour,
about 0 to 5% egg solids,
about 0.1 to 3% salt,
about 0 to 4% emulsifiers,
about 0 to 25% fat, and
about 5 to 25% moisture;
said batter having
a sugar to flour ratio of about 1.5:1 to 3.5:1,
a water activity of less than 0.85,
a pH of about 6 to 8.5; and
can be made with or without any leavening system.
The leavening system either consists of sufficient amounts of N
2
O aerated into the batter to a density of about 1.00 to 1.2 g/cc or can be made with no aeration and just chemical leavening or can be made without any gas or chemical leavening; or a combination of above;
filling the headspace portion of the container that is unfilled with the batter with an inert gas having an oxygen content of less then 4%; and
sealing the container to form a shelf stable ready-to-bake brownie article.
