Researchers Submit Patent Application, “Curd Containing Slurry Compositions for Making Soft Or Firm/Semi-Hard Ripened and Unripened Cheese”, for Approval
By a News Reporter-Staff News Editor at Life Science Weekly — From Washington, D.C., NewsRx journalists report that a patent application by the inventors Merrill, Richard K. (Highlands Ranch, CO); Singh, Mayank (Aurora, CO), filed on October 28, 2013, was made available online on July 3, 2014 (see also Leprino Foods Company).
The patent’s assignee is Leprino Foods Company.
News editors obtained the following quote from the background information supplied by the inventors: “Recently there has been an increase in the demand for cheeses that have widely differing performance characteristics. This particular demand is driven in part by the increasing variety of prepared foods in which such cheeses are included. In fact, there often is a need for different performance qualities even for foods of the same general type because of the different ways cheese is utilized or because the cheese is exposed to differing cooking environments or conditions. Pizzas illustrate this point well because there are so many different types of pizzas. Pizzas, for example, have widely differing crusts, including thick, thin, or somewhere in between. The cheese can also be exposed or wrapped in the edge of the crust. Furthermore, the crust may be completely uncooked or it may be prebaked before being put in the oven with the cheese. Each of these variables potentially impacts the composition of the cheese required to provide satisfactory performance.
“Demand for cheese with varying performance characteristics is also driven in part by the significant increase in the different types of baking equipment and conditions that are being used to prepare food products containing soft or firm/semi-hard cheese. Some baking operations, for instance, require relatively high oven temperatures (e.g., in the range of about 350 to 950.degree. F. (177-510.degree. C.)) with short baking times (e.g., in the range of about 30 seconds to 15 minutes). Such conditions may be used, for instance, in an impingement oven when baking a pizza having a thin crust. Other ovens, such as deck ovens, in contrast, sometimes use a relatively long bake time (e.g., about 6 to 60 minutes) and a correspondingly lower oven temperature (e.g., about 300 to 750.degree. F. (149 to 399.degree. C.)). Instead of baking, some foods topped with or including soft or firm/semi-hard cheese are prepared by microwaving (e.g., about 1-6 minutes).
“Consumer demand for cheeses with improved nutritional content (e.g., nutritionally balanced, lower fat) has also increased the demand for new varieties of soft or firm/semi-hard cheese.
“There are a variety of challenges to providing cheeses that have a composition which satisfies the desired performance characteristics and nutritional qualities. For instance, it can be difficult to obtain the desired concentration level of some ingredients in a cheese. Another problem is developing a process that activates the latent functional properties of certain ingredients. Another problem is that many methods for preparing soft or firm/semi-hard cheese involve the loss of significant quantities of some cheese components during processing. This can occur, for instance, when such cheeses undergo the heating and stretching process of the pasta filata process. Often the heating is conducted in heated water, which can remove significant amounts of cheese ingredients.
“In view of the demand for cheese and the foregoing shortcomings associated with some existing methods for preparing cheeses with the desired performance characteristics, there thus remains a need for additional methods for preparing cheeses of various types.”
As a supplement to the background information on this patent application, NewsRx correspondents also obtained the inventors’ summary information for this patent application: “A variety of methods for preparing soft or firm/semi-hard ripened or unripened cheese are provided. Cheese produced by the methods and systems for conducting the methods are also provided.
“Some cheese manufacturing methods involve blending a cheese curd and one or more ingredients together to form a slurry. The slurry is processed by performing one or more processes selected from the group consisting of cooking the slurry, subjecting the slurry to high shear conditions, homogenizing the slurry, and adjusting the moisture content of the slurry. Once the slurry has been processed, one or more additional ingredients can be mixed into the slurry to form an admixture. The resulting admixture is formed into a cheese. In some methods, the slurry is cooked in the absence of exogenous water.
“The ingredients blended into the slurry can be selected from a wide variety of ingredients including, but not limited to, nonfat dry milk, a milk protein, an acidity regulator, an acid, an anticaking agent, an antifoaming agent, a coloring agent, an emulsifier, an enzyme preparation, a flavoring agent, a firming agent, a food protein, a gelling agent, a preservative, sequestrants, a stabilizer, a starch, a thickener, an oil, a fat, a cheese powder, a salt, a nutritional supplement, an acid, an enzyme, a neutraceutical, a carbohydrate, a vitamin, and a mineral. Examples may further include procream, whey cream, a dairy solid, and foodstuffs of vegetable, fruit and/or animal source. The foodstuffs may include fruit, vegetables, nuts, meat, and spices, among other foodstuffs.
“Other methods for preparing cheese involve blending a cheese curd, and optionally water and/or one or more ingredients, to form a slurry. The slurry is processed by cooking the slurry and performing one or more processes selected from the group consisting of subjecting the slurry to high shear conditions, homogenizing the slurry and adjusting the moisture content of the slurry. The processed slurry is then shaped and cooled to form the soft or firm/semi-hard cheese.
“Still other cheese preparation methods involve providing an admixture that comprises a cheese curd and one or more ingredients selected from the group consisting of a starch, a dairy solid, a gum and a cellulose agent. The admixture is then shaped and cooled to form the soft or firm/semi-soft cheese. In some methods, the concentration of the starch, the dairy solid, the gum or the cellulose agent in the admixture is sufficient such that the soft or firm/semi-hard cheese that is produced has one or more of the following characteristics (i) a starch concentration of at least 0.1 wt \%, (ii) a dairy solid concentration of at least 0.1 wt \%, or (iii) a gum or cellulose agent concentration of at least 0.1 wt \%.
“Methods for preparing a slurry that can be used in the preparation of a soft or firm/semi-hard ripened or unripened cheese are also disclosed. Some of these methods involve blending a cheese curd and one or more ingredients together to form a slurry. The slurry is then processed by heating the slurry to a temperature of about 90.degree. F. to about 293.degree. F. and performing one or more of the processes selected from the group consisting of subjecting the slurry to high shear conditions, homogenizing the slurry, and adjusting the moisture content of the slurry to about 36 to 65 wt. \%, thereby forming the heated slurry.
“Also included are slurries that can be used in the preparation of a soft or firm/semi-hard ripened or unripened cheese. Some slurries include a cheese curd and one or more ingredients, wherein the one or more ingredients are selected from the group consisting of a starch, a dairy solid, a gum and a cellulose agent, and wherein the slurry may have one or more of the following characteristics (i) a starch concentration of at least 12 wt \% or (ii) a dairy solid concentration of at least 12 wt \%, or (iii) a gum or cellulose concentration of at least 12 wt \%.
“Cheese manufacturing systems are also provided. Certain of these systems comprise a slurry preparation system, which itself includes a blender adapted to blend a cheese curd and one or more ingredients together to form a slurry and a first dispenser operatively disposed to introduce the one or more ingredients into the slurry. The slurry preparation system also includes a subsystem comprising at least one of the following units (i) a cooker adapted to heat the slurry to a temperature of about 90.degree. F. to about 293.degree. F.; (ii) a shear pump adapted to subject the slurry to high shear conditions; and (iii) a homogenizer adapted to homogenize the one or more ingredients in the slurry; and (iv) an evaporator adapted to adjust the water content of the slurry to about 35-65\% by weight, wherein at least one unit is in communication with the blender and the units within the subsystem are in fluid communication.
“The manufacturing system also includes a second dispenser and a mixer operatively disposed to receive the slurry from the slurry preparation system and to receive one or more ingredients from the second dispenser, and adapted to mix the slurry with the one or more ingredients to form an admixture. Finally, the manufacturing system includes a final processing system operatively disposed to receive the admixture and adapted to form a final cheese product.
“Soft and firm/semi-hard cheeses produced by the methods disclosed herein are also provided.
