The present application is directed to a process for cooking grains in a sealed loose package with a brine and water that results in loose and fluffy cooked grains.
Traditionally, grains are open cooked in water so that they can absorb moisture and expand during cooking. There are problems with other methods for cooking grains. For example, in a sous vide style process (i.e., vacuum cooking in a bag), the grains could not expand properly during cooking. The grains could also congeal into blocks due to starch gelatinization.
Current “cook in water” products in the market cook grains in perforated bags that are submerged in boiling water. The water is then drained from the bag after cooking. However, cooked grains in this manner, or grains that are packed after being cooked can experience post thermal process contamination issues, and physical and/or chemical intervention is needed to prolong a refrigerated shelf life of the product.
The present invention provides a method for cooking grains in a bag without perforations that provides a fluffy cooked product.
The present invention is generally directed to a process for cooking grains, such as rice, oats etc., in a sealed loose package that cooks the grains in a manner to provide an appealing product without concern for contamination if the product is maintained in the bag. The cooked grains are loose and fluffy and are not congealed together. Additionally, the product has long refrigeration shelf life without additional chemical or physical intervention.
In accordance with one aspect of the invention, a process for cooking grains comprises providing a bag having an air and moisture barrier, and placing uncooked grains in the bag. The process further includes placing brine in the bag and providing a head space filled with air in the bag to provide space for the grains to expand during cooking. The process also includes sealing the bag and cooking the grains in the bag. The steps of placing uncooked grains in the bag, placing brine in the bag, providing a head space filled with air in the bag to provide space for the grains to expand during cooking, and sealing the bag are performed in a packaging machine.
The step of cooking the grains in the bag can comprise submerging the bag in hot water. Alternatively, the step of cooking the grains in the bag comprises placing the bag on a rack in a cabinet and exposing the bag to steam, hot air or a hot water fall.
In another alternative, the step of cooking the grains in the bag comprises placing the bag in a rotating and agitating cooking device. The rotating and agitating cooking device can be a rotary drum cooker.
In yet another alternative, the step of cooking the grains in the bag comprises placing the bag in a continuous cooking system having multiple cooking zones. The continuous cooking system can include bag flipping capability and the process further comprises flipping the bag between the cooking zones.
The grain is completely cooked in the bag and then refrigerated in the sealed bag. The grain can be rice or oats or other similar grains.
In accordance with another aspect of the invention, a process for cooking grains in a bag to provide a loose and fluffy cooked grain product is provided. The process comprises providing a packaging machine and providing a bag having an air and moisture barrier. The process further includes filling a portion of the bag with a grain using the packaging machine, filling a portion of the bag with brine using the packaging machine, leaving a portion of the bag with only air, and sealing the bag using the packaging machine. The process further includes providing a cooking device and cooking the grain in the bag in the cooking device.
The step of providing a cooking device can include providing a rotating cooking device. Alternatively, the step of providing a cooking device can include providing a continuous cooking device with multiple cooking zones or providing a cabinet with racks for one of cooking by steam, hot air and a hot water fall.
The step of filling a portion of the bag with a grain using the packaging machine includes filling the bag with rice or oats or other similar grain product.
Other features and advantages of the invention will be apparent from the following specification taken in conjunction with the following Figures.
To understand the present invention, it will now be described by way of example, with reference to the accompanying drawings in which:
While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
The present invention provides a method for cooking grains in a sealed loose package or bag that results in a loose, fluffy cooked product. The cooked bag has a long refrigerated shelf life without the need for chemical or physical intervention to prevent contamination of the grain in the bag.
The packaging machine 10 fills only a portion of the bag 12 with a grain 14 product. The packaging machine 10 also fills only a portion of the bag 12 with a brine and water mixture 16. The remainder of the bag 12 is left empty, that is, the bag 12 is left with only air in it. In some instances, air (or possibly other gases) can be forced into the bag 12. The bag 12 is then completely sealed, again, leaving a portion of the bag 12 just filled with air. Importantly, the bag 12 is not vacuum sealed as is done in some other cooking methods. This is because the extra space in the bag 12 is provided to allow the individual grains 14 to expand as they absorb the brine and water mixture.
The grain 14 in the bag 12 can then be cooked in a number of ways. For example, the bag 12 can be submerged in hot or boiling water in a pot.
In a static cooking method like that shown in
Alternatively, a cooker with multiple cooking zones and flipping capability can be utilized. A Marlen double zone continuous cooker 24 with such bag flipping capability is shown in
The grain 14 is completely cooked in the sealed bag 12 and is not opened until ready to use. There is no post thermal processing contamination which provides food safety and better refrigerated product shelf life.
Many modifications and variations of the present invention are possible in light of the above teachings. It is, therefore, to be understood within the scope of the appended claims the invention may be protected otherwise than as specifically described.
The present invention claims priority to and the benefit of U.S. Provisional Patent Application No. 63/460,345 filed Apr. 19, 2023, the contents of which are incorporated herein by reference and made a part hereof.
