Abstract

Abstract of the Disclosure A cheese-like product is derived from dry rennet casein and generally exhibits the body, texture and eating quality of cheese. The cheese-like product is a substantially homogeneous mass of predetermined consistency and contains at least about 25 percent by weight of previously dry but solvated edible rennet casein as the principal protein source, a solvation agent and water. A bland edible oil or fat and a suitable flavoring agent (or agents) can be present in quantities sufficient to impart to the product the characteristic fat content and flavor of the desired cheese analog. A coloring agent may also be present.
The cheese-like product is produced by the direct conversion of dry, particulate rennet casein to a substantially homogeneous mass of cheese-like consistency at an elevated temperature.

Description

This invention relates to cheese-like products and to a method for direct fabrication of such products.
Imitation cheese products have been produced from a variety of protein sources such as cottage cheese curd, milk solids, skim milk solids and the like. In many instances the above protein sources have been combined with minor amounts of the cheese being simulated and act as an extender therefor.
In recent years, alkali or alkaline earth metal caseinates, which are valuable sources of protein, also have been used in the production of process cheese products as is illustrated by United States Patent No.
3,922,374 to Bell et al. However, such caseinates sometimes possess an objectionable odor and flavor which can override the intended flavor of the produced food products.
Some relatively bland caseinates have been produced by heating a casein solution with an alkali metal or an alkaline earth metal salt in a manner which causes coagulation of the protein. The resulting coagulum is separated fTom a continuous liquid phase, and, afteT washing, is a substantially bland alkali or alkaline earth metal caseinate. Sodium caseinate, calcium caseinate and sodium-calcium caseinate have been employed heretofoTe for the production of simulated process cheese products.
Nevertheless, a number of problems are inherent in the use of such materials.
For example, in some instances sodium caseinate is unsatisfactory in imitation cheese pToducts because such imitation cheese products have a tendency toward burning and puffing if baked OT toasted, for example, on pizzas OT on open-faced, toasted B~ -2-sandwiches ~o~eve~, caC--jn~tes are ofteo used as extenders in simulated dairy products so that smaller amounts of the more expensive natural ingredient can be utilized in the product.
Another drawback of caseinates is that they are rela-tively expensive and t~nd to develop objectionable flavors and odors.
Wet mass rennet casein (e.g., cottage cheese curd) has also been used to manufacture cheese products; however, it is a perishable item and suffers from the problems of spoilage, in-convenient handling and storage.
German Patent Publication (Offenlegungsschrift) No.23 42 299 discloses a cheese processing additive that can con-tain up to 20 weight percent of rennet casein and that can be added to crude cheese in an amount sufficient to supply 1 to 3 weight percent of rennet casein. However, the rennet casein content of this processing additive is low, and a very large amount ofaphosphatesalt (33 tol00weight percent, based on weight of rennet casein) is used to produce the additive.
Accordingly, there has been a longstanding need for an inexpensive protein source which can be utilized as the principal protein source to produce a satisfactory food product and which can be used, if necessary, as the sole protein source in a cheese analog or cheese-like product. It has now been found that a non-cultured, cheese-like product can be prepared using dry, particulate rennet casein as the principal, or sole, protein source of the product, notwithstanding the known rela-tively low solubility of rennet casein in aqueous systems.
Summary of the Invention The present invention contemplates solvation of dry particulate rennet casein in water in the presence of an edible solvation agent to produce a paste-like mass of predetermined consistency.
Accordingly, the invention provides a non-cultured, simulated food product having generally the texture, body and taste characteristics of cheese which is a substantially homogeneous mass comprising at least about 25 percent by weight previously dry but solvated edible rennet casein, an edible solvation agent present in an amount of about 2 to about 12 percent by weight of said rennet casein, water, a bland, edible lipid material selected from the group consisting of oil and fat, and sufficient quantities of suitable flavoring agents to impart the desired flavor.
The important factors for the direct fabrication of cheese analogs according to the present process are the relative amounts of the dry rennet casein, the solvation agent, and water. The manner in which these components are combined to constitute the mixture that is subjected to the heat treatment can be varied to provide various textures and products. The individual components can be premixed, mixed in the cooker, or a combination of the foregoing procedures can be utilized. The nature of the heat treatment and agitation to which the foregoing components are subjected during processing also have a bearing on the obtained product.
The cheese-like product of this invention is based on a substan-tially homogeneous mass comprising at least about 25 percent by weight of previously dry but solvated edible rennet casein as the principal protein source, a solvation agent and water. A bland edible lipid material, i.e., an edible oil or fat, and a suitable flavoring agent (or agents) can be present in quantities sufficient to impart to the product the characteristic fat content and flavor of the desired cheese analog. A coloring agent usually is also present. Salt and other protein constituents can be added as desired.
In the process of this invention, the dry, particulate rennet casein is solvated or hydrated at an elevated temperature with sufficient 3a water to produce a paste-like mass having no discernible unsolvated rennet ar~7 casein particles present. The solvation is carried out with agitation in the presence of a solvation agent and at a temperature of about 150F. to about ' -4a-3C0 F. F ~-?r~ / i a~ a,Q,lt 190?F to ab~ 2~ P Tl~e ~ n~
period during which solvation of the rennet casein is comple~ed is about 30 seconds to about lO minutes, preferably about 2 to about 4 minutes.
The produced cheese analog or non-dairy but cheese-like product can be cast into loaves, sliced, or shaped into other packaging configurations as desired.
Detailed Description of the Preferred Embodiments More specifically, a non-cultured cheese analog embody-ing this invention is a smooth, homogeneous plastic or non-plastic mass wherein the principal, and in many instances the sole, protein source for the cheese analog is previously dry but now solvated edible rennet casein, present in an amount of at least about 25 percent by weight of the total product. The rennet casein content can be as high as about 65 percent by weight, or higher, if desired, as long as the produced mass is substantially homogeneous and no visually observable, discrete rennet casein particles are present. Preferably the rennet casein content is about 30 percent to about 45 percent by weight.
Rennet casein is a commercially available edible milk protein product which contains more of the milk minerals than does acid casein. Typically, edible rennet casein is isolated by methods well known in the art from fresh pasteurized skim milk of relatively low fat content by precipitation with a rennet-type enzyme of the type used in cheesemaking. The pre-cipitating enzyme can be of either animal or microbial origin.
The precipitated rennet casein is then washed, pressed, dried, ground, sieved and blended to provide a substantially uniform, particulate productO
It is preferred to use a dry, particulate rennet casein having a lactose content of about O.l percent to about 0.3percent by weight and havi~lg a p~ le s ' ~ appr~ximately 30 mesh.
Preferably, the ash cGnten-. of ~he dry, particulate rennet casein that is used as the starting material is at least about 6 wt.-%, and more preferably about 7.5 wt.-%. One commercial source of suitable dry, particulate, edible rennet casein is New Zealand Milk Products, Inc., 6300 River Road, Rosemont, Illinois. A typical batch of this particular edible rennet casein has the following analysis:

Moisture 11.0 Protein (N x 6.38) 80.6 Milkfat 0.5 Lactose 0.1 Mineral salts (ash) 7.8 100.O

Calcium 2.7-3.0 Phosphorus 1.3-1.4 Magnesium 0.10-0.12 Sodium 0.01-0.05 Potassium 0.01-0.04 Iron 2-6 mg/kg The term "solvated" as used herein and in the appended claims characterizes previously dry, edible rennet casein that has been hydrated at an elevated temperature and dispersed in an aqueous system as a solution or a gel.
The dry rennet casein has a number of advantages as the protein source. It is relatively inexpensive, and, because of its dry form, can be stored for long periods of time without ,oil~* o ~jss o~ ~,avor which ~is a prc~hl~ wi~h _aseinates, cott;~ge ul2ese ~urd, milk solids and other typ;cal protein com-ponents of currently available process cheese products, many of which cannot be used as the sole protein source. However, heretofore it was no-~ known how to produce stable aqueous sys-tems having a relatively high rennet casein content, i.e., a rennet casein con-~ent in excess of about 20 weight percent.
Neither enzymes nor microorganisms are employed in the production of imitation, non-cultured, cheese-like products of this invention, thus the present invention provides a rela-tively simple, economical process of relatively short duration to produce a superior non-cultured, non-dairy, cheese-like product. The product of this invention can be made at a much lower cost than currently available imitation cheese products.
Furthe:rmore, by direct processing, i.e., by the direct conversion of dry~ particulate edible rennet casein according to the method of this invention, a simulated non-cultured cheese-like product which closely resembles a natural cheese in body, texture and flavor characteristics can be obtained. Thus the present invention has provided a relatively simple, but economical and superior advance in the art of cheese analogs and their formu-lation.
The lipid material, i.e., the fat or oil, portion of the produced edible composition may be constituted by any edible fat or oil having a clean, bland flavor and preferably melting at a temperature of about 50F. to about 100F., more preferably at about 90F. to about 95F. The solid fat index of the oil at 92F. preferably is less than about 6, and more preferably about 0. The preferred oils or fats for the present purposes are animal fat such as milk fat, hydrogenated or partially hydro-genated vegetable oils such as coconut oil~ corn oil, palm oil, s soybean oi]J -~o~t,insee~ 11, safflower o l or mixtures such as soybean-cottonseed oil blends, and the like. The oil or ~at portion constitutes at least about 7 percent by weight, usually about 7 to about 55 percent by weight of the total product composition, and preferably from about 20 to about 30 percent by weight thereof, depending on the type of cheese analog that is produced.
Edible solvation agents such as the phosphate or citrate salts capable of sequestering the calcium present in the dry, par-ticulate rennet casein are employed in amounts of about 2 to about12 percent by weight of the rennet casein present, depending on the desired body and texture of the cheese-like product. However, if the solvation agent content is less than about 2 percent, incomplete solvation and excessive syneresis will occur. On the other hand, a solvation agent content in excess of about 12 per-cent by weight produces no additional benefits.
At a relatively high edible solvation agent content, i.e., at about 8 to about 12 weight percent, based on the weight of rennet casein present, solvation provides a homogeneous plas-tic mass that has a smooth, uniform body like that of processcheese and is free flowing at elevated temperatures. At an intermediate edible solvation agent content of about 4 to about 8 weight percent, based on the weight of rennet casein present, a relatively long or semi-plastic body is obtained for the sol-vated rennet casein mass. Similarly, at a relatively low solva-tion agent content of about 2 to about 4 weight percent, based on the weight of the rennet casein present, a relatively short body, exhibiting some brittleness, is obtained.
Suitable phosphate-containing solvation agents include edible salts such as the alkali metal phosphates, e.g., disodium phosphate, trisodium phosphate, sodium hexametaphosphate, sodium tripolyphosphate, tetrasodium phosphate, dipotassium phosphate, monosodium dipl!~sl;~,a,e, disodium d;~hosp~ate, t ~sodium diphos~-phate, ~etrasodium diphosphate and ~Ihe llke, ~he sodium aluminum phosphates, and mixtures thereof. A preferred phosphate-contain-ing solvation agent for the production of simulated process cheese is a mixture of trisodium phosphate and disodium phosphate in a weight ratio of about 1:1.5, the mix~ure being present in an amount of about 8 to about 12 percent by weight of rennet casein, depending on the desired degree of plasticity for the body there-of. Another preferred solvation agent is an autogeneous mixture of an alkaline sodium aluminum phosphate having approximate empirical formula NaBAl2(OH)2(PO4)4 with about 30 weight percent of dibasic sodium phosphate. Suitable citrate-containing solva-tion agents include, for example, monosodium citrate, disodium citrate, trisodium citrate, and the like. Other solvation agents, e.g., chelating agents, sequestrants, or the like, can also be used.
Water is present in an amount of at least about 35 to about 300 percent, based on the amount of rennet casein present, and generally constitutes about 30 to about 60 percent by weight of the composition, depending upon the desired consistency.
Water can be added during the premixing and cooking stages of the manufacturing process of this invention. The water that is present serves a two-fold purpose, namely, solvation of the rennet casein and control of consistency. If too much water is added, the resulting solvated mass becomes too fluid and no longer resembles the body of a cheese.
Starter distillate, an acidulant, and salt are gener-ally added for flavoring. The normal pH for the product obtained after cooking and without an acidulant pxesent is approximately 7, therefore, an acidulant such as lactic acid or the like is used in flavoring the cheese-like product and at the same time ' lowers the ~ e il ~rol3~1ct to a des;red pH Yalue o~ ahout 5.4 to about 6.5, for a process cheese-like product preferably about 5.5 to about 5.8.
Since both dry, particulate rennet casein and edible oils are bland in flavor, it is desirable to add a small amount of a flavoring agent, such as starter distillate, natural cheese flavors, or artificial cheese flavors. Starter distillate is a standard commercial product which is widely used by dairy product manufacturers to add flavor to butter, margarine and cheese, and to fortify the flavor of cultured buttermilk and other dairy products, and is equally well suited for use in the present cheese-like compositions. Starter distillate is made by cultur-ing a buttermilk starter to a rich flavor and aroma, and then distilling the volatile flavor constituents therefrom with steam and under very accurate controlled conditions. For the products of the present invention using a standard commercially available single-strength starter distillate as the principal flavoring agent, the desired flavor effect is achieved when the flavoring agent reaches a concentration of about 0.3 to about 0.5 percent by weight, preferably about 0.35 to about 0.4 percent by weight of the ultimate composition.
Alternatively, the chief component or components of starter distillate may be added in their pure form. For example, diacetyl (i.e., 2,3-butane-dione) is the chief flavor component of starter distillate and may be added alone, or together with the acidulant (e.g., lactic acid, citric acid, glucono-delta-lactone, hydrochloric acid, or the like) to achieve a flavoring agent concentration of from about 10 to about 1500 parts per million parts of the ultimate product. Other flavoring and/or acidifying agents that may be added are acetic acid, butyric acid~ propionic aci~ 5 i.e.~ C,~8 carboxylic acids or mixtures thereof. In addition, artificial flavoring agents and/or spices may be used in appropriate amounts to supplement or replace the starter distillate components entirely. However, the preferred flavoring agent is starter distillate, which, in combination with desired levels of salt and acidulant, impart a pleasing flavor that closely approximates the flavor of cheese.
The method of making a simulated, non-cultured cheese-like product directly from rennet casein according to the prac-tice of this invention can include premixing of the dry rennetcasein, solvation agent, and water in an amount which constitutes a major portion of the total water content of the ultimately pro-duced product, with or without the lipid material or flavoring agents present, or the ultimate food product constituents can be mixed within the processing vessel. Thereafter, the produced admixture, containing a portion of the remaining water, is agitated and heated to a temperature of at least about 150F.
and up to about 300F., preferably about 190F. to about 205F.
at atmospheric pressure, and held at that temperature until the rennet casein present is solvated and a smooth mass is achieved, preferably for about 30 seconds to about 10 minutes, and more preferably for about 2 to about 4 minutes. At temperatures above the boiling point of water, processing can be carried out in a suitable pressure vessel. The remainder of the water to the admixture can be furnished via the steam and/or water separately introduced into the cooker before or during the cooking step, depending on the type of cooker that is being used. The produced smooth mass containing solvated rennet casein as the principal protein source is then formed into the desired product shape. In instances where the cooking is done by direct steam, the condensate obtained from the steam supplies the water necessary to bring the water content of the ultimate ~Z~5 ;_roduct 'co the d~sired value. If indirect hea;-~}-,~- is used, more water is added to the cooker during the cooking operation.
For cheese analogs having a relatively high solvated rennet casein content, i.e., above about 50 percent by weight of the composition, it is preferable to add the dry rennet casein to hot water gradually over a period of time.
Premixing of the aforementioned ingredients is not always necessary, however. As pointed out hereinabove, all or a portion of the ingredients can be blended together in the cooker, if desired.
It is important to agitate the admixture of ingredients during heating. Moreover, severity of agitation at processing temperature can be used to further adjust the body of the ulti-mately produced cheese analog. For instance, a relatively high shear agitation is desirable for a plastic body such as that for a process cheese analog. On the other hand, for a cheese analog having a relatively short body, e.g., blue cheese or feta cheese, less severe agitation is normally used.
The following examples further illustrate this inven-tion.
EXAMPLE 1: Preparation of Non-Dairy Premix Dry, particulate edible rennet casein (about 297.5 lbs.) was combined in a blender with trisodium phosphate (about 11 lbs., 10 oz.), disodium phosphate (about 17 lbs., 12 oz.), salt (about 17 lbs., 6 oz.), process cheese color (carotenal No.
73; about 350 ml.), water (about 308 lbs., 8 oz.), coconut oil (about 218 lbs.), lactic acid (about 12 lbs., 8 oz.; about 4625 ml.), starter distillate (about 3 lbs., 7 oz.; about 1544 ml.).
The premix ingredients were then mixed for about 3 minutes to achieve a substantially uniform blend which can be used as a premix for the manufacture of cheese-like products.

EXAMPLE 2: ~repd~ n of Simula,'~d Non Cultwred Process Cheese Product An aliquot of pre-blended non-dairy premix (about 410 pounds) produced in accordance with the method of Example 1 was fed into a Rietz direct steam cooker to which had been previously added about 5 pounds of water. Steam feed to the cooker was partially turned on before the non~dairy premix was fed into the cooker. After the non-dairy premix was introduced into the cooker, the entire steam feed that was available was fed into the cooker. As soon as the mixture in the cooker began to back-splash, the steam feed was cut to about one-half of the original volumetric rate and the mixture was cooked at a temperature of about 195F. The steam feed was then shut off and additional water (about 7.5 lbs.) was stirred into the mixture in the cooker together with sufficient acidulant to provide a pH of about 5.7 for the product. Thereafter, the cooked mixture was discharged into a suitable finish processing apparatus for packaging of the produced process cheese analog.

EXAMPLE 3: Preparation of Simulated American Cheese Product Dry, particulate edible rennet casein (about 220 lbs.), sodium citrate (about 18 lbs.), trisodium phosphate (about 6 lbs.), salt (about 11.5 lbs.), and water (about 267 lbs.) were placed in a blender and mixed at ambient conditions until a substantially homogeneous blend was obtained. A mixture of partially hydrogenated cottonseed oil and partially hydrogenated soybean oil (about 160.5 lbs) was then stirred into the pre-viously produced blend and thereafter citric acid (about 9.7 lbs.), carotenal No. 73 color (about 0.6 lbs.), starter distil-late (about 2.5 lbs.), de-lactosed whey (about 1.9 lbs.), mustard (about 1.9 lbs.), and a vitamin-mineral premix (Hoffman-LaRoche TSD 7267~ grdl.lsj were mixed iJltO the produced blend and -,;~* mixing continued for about three minutes.
The resulting admixture was then barreled off into finished cook weight of about 450 lbs., ground, and fed into a Rietz direct steam cooker. Steam was then fed into the cooker until the cooker contents reached a temperature of about 195F.
Thereafter the cooker contents was turned for about three minutes while being cooked at about this temperature.
The cooked contents of the Rietz direct steam cooker was then extruded into individually wrapped slices and cooled to ambient temperature. A simulated American cheese product having a pH of about 5.5 to 5.6 was obtained.
EXAMPLE 4: An Edible Cheese Analog To water (about 26.4 kg.) in a blender were added disodium phosphate (about 2 kg.) and sodium chloride (about 4 kg.), and dissolved therein. Dry, particulate edible rennet casein (about 30.8 kg.) was thereafter stirred into the result-ing solution followed by vegetable oil (about 25 kg.), flavor-ing agents, and glucono-delta-lactone (about 3 kg.). The resulting admixture was then thoroughly agitated until substan-tially homogeneous, fed to a direct steam cooker, and cooked therein at about 170F. to about 180F. for about three minutes.
A smooth, fluid mass was obtained, which was then filled into containers and rapidly cooled to ambient temperature.
The ultimately obtained edible product was cheese-like in ap-pearance and taste, and exhibited a relatively short, somewhat brittle body.
EXAMPLE 5: Preparation of Solvated Rennet_Casein Dry, particulate edible rennet casein was admixed with water and with disodium phosphate (DSP) as the solvation agent'copr,iii~ J,:am batches that were individually pro-cessed in a douhle boiler capable of heating the contents thereof to a temperature of about 190F. to about 200F. (Runs A -C).
In Runs D-F a portion of the rennet casein was added gradually during the course of heating to maximum temperature.
The boiler contents in each instance was then agitated with a portable agitator having a variable speed drive. Each batch was held at the maximum attainable boiler temperature for about 2 to 3 minutes while being agitated and then cooled. All batches were subjected to about the same degree of agitation.
The experimental results are compiled in Table I, below.
