[0033] The present invention discloses a method 100 for preparing a vegan cheese, according to an illustrative embodiment as depicted in FIG. 1. The vegan cheese may be described as a cheese “substitute” or “replica” that serves a role as food or in food that is commonly served by traditional dairy cheese. The vegan cheese of the current disclosure is a vegan product that shares visual, olfactory, textural or taste characteristics of cheese such that an ordinary human observer of the product is induced to think of traditional dairy cheese. As illustrated in FIG. 1, the method 100 includes a number of steps, however, sequence of the method steps disclosed hereinafter are exemplary for the sake of understanding the invention for persons skilled in the art. The method 100 starts at step 101 and proceeds to step 102 where an emulsion of non-dairy milk is obtained from various sources. Preferably, the non-dairy milk and/or emulsion is obtained from various plant based sources. In an embodiment of the present invention, the non-dairy milk emulsion may be obtained directly as a liquid from the plant source. In other embodiments, the non-dairy milk/emulsion is prepared using a protein portion of the plant source. In such an embodiment, the protein portion of the plant source is first extracted/obtained from the plant source using various known mechanism as applicable. Thereafter, the protein source is washed and cleaned in sterilized water and optionally in some instances, is first sterilized and then washed in sterilized water in order to get rid of any external contamination of fungi, bacteria, insects, or the like. Thereafter, the protein portion is blended to an emulsion that resembles a milk, using any appropriate tool such as a blender, or the like. Further in such examples, any fibrous material present in the milk is removed using filtering techniques such as centrifugal extraction, fine mess sieve filtering, or the like.

[0034] In an embodiment of the present invention, the protein portion may be one or more component of the plant sources such as endosperm flesh, pericarp pulps of fruits, leaf and stem and inflorescence (flower) parts of vegetables, plant tubers, plant bulbs or the like.

[0035] In some examples, the plant source for obtaining non-dairy milk may be selected from one or more fruits selected from the group consisting of but not limited to Coconut Coco nucifera, Palmyrah palm fruit, Borassus flabellifer, Jack fruit, Artocarpus heterophyllus, Marang (woolly jack fruit), Artiocarpus odoratisssmus, Durian, Durio zibethinus, Fam. Malvaceae, Mango, Mangifera indica, Avocado, Persea Americana, Tomato, Solanum lycopersicum/Lycopersicon esculentum, Mawang (jungle mango like fruit), Mangifera panjang Kostermans, Dates, Phoenix dactylifera, Dried apricot, Prunus armeniaca, Guava, Psidium guajava, Mulberries, Morus nigra, or the like.

[0036] In yet other examples, the plant source for obtaining non-dairy milk may be selected from one or more seeds/kernels selected from the group consisting of but not limited to Chick pea, Cicer arietinum, Rice, Oriza sativa, Finger millet, Eleusine coracana, or the like.

[0037] In yet other examples, the plant source for obtaining non-dairy milk may be selected from one or more vegetables from the group consisting of but not limited to Kale, Brassica oleracea, White cabbage, Brassica oleracea var. oleracea, Jerusalem artichoke, Helianthus tuberosus, Artichoke, Cynara cardunculus var. scolymus, Broccoli, Brassica oleracea, Butternut squash, Cucurbita moschata, Pumpkin squash, Cucurbita pepo, White button mushroom, Creeper Spinach, Basella alba, Pumpkin, Curcubita pepo, Sweet corn, Zea mays convar. saccharata var. rugosa, or the like.

[0038] The method 100 then proceeds to step 104, where the non-dairy milk obtained from the plant source is brought to a right temperature suitable for curdling. Such a temperature is achieved by heating the non-dairy milk slowly. In some embodiments, the emulsion is heated directly by pouring the emulsion in a pot and putting it directly on electric stove top. In other embodiments, the emulsion is control-heated to a temperature ranging between 75° C. and 90° C. by keeping the pot in a hot water bath. Once the emulsion/milk is heated, the emulsion is removed from heating and kept to cool down to a temperature ranging between 30° C. to 35° C. Further, pH of the emulsion/milk is also controlled to a desired level. Once the emulsion achieves a temperature suitable for curdling, the method proceeds to step 106 where the non-dairy milk is curdled for at least 18 hours, or at least 24 hours, or at least 36 hours, or at least 48 hours, or up to 72 hours, using a curdling process 200. The curdling time is dependent on the type of non-diary milk and the type of rennet used. Fore example, coconut milk may need about 24 hours, while butternut milk needs longer curdling times than 24 hours and avocado based milk may need about 48 hours or longer to curdle. Curdling coconut milk with Cynara rennet may need about 24 hours while curdling with thorn apple Solanum incanum rennet may need about 3 days to produce a curd sufficiently thickened to make excellent cheese. In addition, the curdling time is also dependent on the cheese profile. For example, a minimum of 40 hours of curdling are necessary to create Emmental flavours.

[0039] The method 200 starts at step 201 and proceeds to step 202 where one or more inorganic salt is added to the non-dairy milk to start a coagulation thereof. In some embodiments of the present invention, the inorganic salt is a cation salt selected from one or more of the group consisting of but not limited to CaCl2, MgSO4, MgCl2, KNO3, CaSO4, CaCO3, NaHCO.sub.3, K2CO3, Ca(OH)2 and NaHPO4. In other embodiments, any suitable coagulating salt may be added to start the coagulation of the non-dairy milk. In some other embodiments, a vinegar may be added to start the coagulation of the non-dairy milk. Optionally, one or more acids such as a citric acid or a lactic acid is added in very small amount to keep the pH level within the desired range. The method 200 then proceeds to step 204, where a predetermined amount of starter culture is added to the non-dairy milk/emulsion. In an embodiment, the amount of starter culture added ranges between of 1 mil to 5 ml per litre of non-dairy milk/emulsion. In other embodiments, any suitable amount of starter culture is added to the non-dairy milk/emulsion. The non-dairy milk/emulsion is then mixed by stirring using a ladle after a wait/rest period or 2 minutes to 5 minutes. Such a wait period rehydrates the starter culture and avoids clumping thereof.

[0040] Example of starter culture may include culture formed by different combination of bacteria. In an embodiment, the starter culture is prepared by first preheating the non-dairy milk to 84° C. to 90° C. and then cooled down to 30° C. to 35° C. and then mixed with a mixture of one or more bacteria to a temperature ranging between 60° C. to 70° C. The one or more bacteria may be selected from the group consisting of but not limited to Streptococcus cremoris, Streptococcus lactis, Streptococcus lactis subsp. Diacelactis and Leuconostic cremoris. Thereafter, the mixture is kept at a temperature ranging between 25° C. and 37° C. for a time period ranging between 24 and 36 hours. Thereafter, the mixture is refrigerated at a temperature ranging between 2° C. and 10° C. for a time period ranging between 10 and 20 hours to obtain the ripened starter culture.

[0041] Once the starter culture is added to the non-dairy milk/emulsion, the method proceeds to the step 206 where a plant-origin rennet is added to non-dairy milk/emulsion. Thereafter, the plant-origin rennet is thoroughly mixed with the non-dairy milk using a stirrer so as to spread the enzymes of the rennet and to facilitate enzymatic curdling of the non-dairy milk. The stirring is thorough but only brief and after stirring the milk container is kept undisturbed without moving until the non-dairy milk is completely coagulated and curdled. Complete coagulation and curdling may take at least 18 hours, or at least 24 hours, or at least 36 hours, or at least 48 hours, or up to 72 hours. The plant origin rennet is chosen according to its applicability on the non-dairy milk/emulsion. Such an addition of the plant-origin rennet results in a proper and complete curdling of the non-dairy milk.

[0042] In an embodiment of the present invention, as illustrated in FIG. 3, a method 300 for preparation of plant origin rennet is disclosed. The method 300 starts at step 301 and proceeds to step 302 where dried components such as leaves, fruits, stamens, or the like from the plant rennet sources is obtained. The method 300 then proceeds to step 304 where the dried components of the plant rennet source are powdered using any suitable tool such as powdering mill. Thereafter, at step 306, the powdered dried component of plant rennet source is soaked in an amount of water, preferably a sterilised distilled water of a temperature 53° C. and briefly but thoroughly stirred and after stirring kept still for a period ranging between 15 minutes. After 15 minutes of soaking the solution is filtered (308D with a fine mess sieve and the filtrate liquid either soon after used as plant rennet for curdling the plant origin emulsion/pulp/milk or as shown in step 310, is refrigerated at 6° C. for a time period ranging between one week to two weeks and/or until it is used for curdling the non-dairy milk.

[0043] In particular embodiments, the plant-origin rennet is a rennet obtained from plant sources selected from artichoke, thistles and fig plant (more specifically fig plant latex, fig plant stems, dried fig fruits), mulberry (more specifically dried mulberry stems), or Moringa (more specifically dried Moringa fruit skin, dried Moringa fruit pulp and Moringa plant bark). Looping back to the method 100, once the non-dairy milk is curdled at step 106, preferably for at least 18 hours, or at least 24 hours, in some embodiment of the present inventions, the method 100 proceeds to an optional step 108 where the curd obtained from step 106 is proceed using a number of processes as illustrated in FIG. 4. Such processes may be performed sequentially in any desired order.

[0044] In one example, the step 108 of processing includes a step 108a where cooking of the curd is performed at a desired temperature, generally ranging between 55° C. and 70° C. and thereafter under a refrigerator temperature of 6° C. to 12° C. or at room temperature draining the whey out of the curd is performed for a time period ranging between 3 hours and 44 hours depending on the plant source of non-dairy milk. The step 108 of processing the curd further includes a step 108b where molding of the curd into forms is done. In such a step, the curd is kept on a mould of a predetermined shape and size thereby moulding the curd into a desired formed as according to the shape and size of the mould. In an embodiment, the mould may be made of a stainless steel having a cubical slots of a predetermined size thereby, facilitating a moulding of the curd into cubes of equal sizes. In other embodiments, the mould may be made of any suitable material having any desired shape such as cubic, spherical, or the like. The step 108b is generally performed sequentially after the cooking of curd thereby allowing the curd to keep draining the excess whey after being poured into the mould and kept for draining under refrigerator temperature.

[0045] The step 108 of processing the curd further includes a step 108c of brining the moulded curd. In such a step, the curd is dipped and soaked in a brining solution for a time period ranging between 1 minute and 5 minutes, depending upon the type of brining solution and the cheese type. In an embodiment of present invention, the brining solution may include mainly sea salt and very small amount of CaCl.sub.2) and very small amount of white vinegar. In some soft cheese types instead of brining the curd an appropriate small amount of sea salt is sprinkled on top of the curd either during draining and moulding or after being drained and moulded.

[0046] The step 108 of processing the curd further includes a step 108d addition of a one or more bacterial strain and moulding fungal strain for providing one or more enhanced properties to the cheese to be produced. Here “mould” refers to the inoculating fungus and not metal form-mould to get the right shape of the cheese. In a preferred embodiment, the fungal strain comprises a predetermined amount of a Penicillium camber strain such as Penicillium candidum Neige which when added, provides a desired white rind colour to the surface of the vegan cheese. The Penicillium camber strain may be used in combination with one or more other strains to provide additional properties to the vegan cheese produced. For example, in some instances, the Penicillium candidum Neige is used in combination with Geotrichum Candidum to avoid slippage of top skin from the surface of the finished cheese. In some other embodiments, a bacterial strain of Brevibacterium linens is added instead of the fungus Penicillium candidum Neige. The addition of Brevibacterium linens provides a desired red, orange or yellow rind formation. Further, it also provides other benefits such as imparting a flavour from outside surface of the cheese to inside, preventing the growth of many harmful pathogenic bacteria specially Listeria monocytogenes and other fungi. In some other embodiments both the fungus strain Penicillium candidum Neige and bacterial strain Brevibacterium linens are added to get the right flavour, taste and also the rind colour of the finished ripened cheese.

[0047] The step 108c is generally performed sequentially after the molding of the cheese. In some embodiments, the step of addition of Penicillium camber strain may be performed sequentially after the step of brining the curd. In some other embodiments, the step of addition of Penicillium camber strain alone or also with the addition of Brevibacterium linens together may be performed along with the addition of starter culture so as to inherit a flavor/color to the cheese formed. In some embodiments only Brevibacterium linens without fungus strain Penicillium camber is added along with the addition of starter culture so as to inherit a flavour/colour to the cheese formed.

[0048] In some other embodiments, in which the step 108 of processing the curd is not performed, the method proceeds directly to step 110 from the step 106. At step 110, the curd obtained is ripened to obtain the desired vegan cheese. The ripening may be performed using any known mechanism currently used to ripen the curd. In an embodiment of the present invention, ripening is performed by putting the curd at a predetermined temperature range and relative humidity, preferably keeping the cheese curd moulded forms in maturing cabinets, for a time period ranging between 4 days to 2 months thereby allowing the curd to ripen to a desired texture and flavour and turn into the cheese of that desired texture and flavour.

[0070] When rennet needed dried stem cuttings are soaked in sterile water and rubbed to get extract for rennet. Also dried stem cuttings are powdered to soak in sterile water to extract rennet.

Step 5: Refrigerating the Extracted Rennet

[0071] The Rennet thus produced is either immediately used or stored under refrigerator temperature 6° C. effective up to 2 to 3 weeks.
Result:—The Rennet thus produced can be immediately used or effective up to 2 to 3 weeks if stored under 6° C. refrigerator temperature.

Example 6—Production of Goat Cheese Like Vegan Cheese from Pure Coconut Milk as the Plant Base Material

Step 1: Obtaining Rightly Matured Coconut

[0072] The rightly matured coconut is collected and is then checked for purity and a great care is taken not to collect the coconut that is either spoiled, fermented, or that may be contaminated with any microbe, insect fungi, or the like

Step 2: Prepare Coconut Milk

[0073] The mature coconut is opened by cut opening the de-husked coconut with shell intact. Each coconut is again checked for purity. The coconut meat must be pure white without any colouration (indication of already fungal presence) or rancid smell or pungent pulps or gases when cut opened. Once the purity of the coconut meat is ensured, the coconut white meat is shredded mechanically into fine thin shreds. The shredded coconut meat is then blended in a blender with addition of right limited amount of water and resulting pulp was squeezed and filtered to get a pure white clean milk without any fibrous particle.

Step 3: Preparing the Coconut Milk for Curdling: —

[0074] The coconut milk is first heated to reach a temperature of 84° C. Thereafter the milk is allowed to cool down to a temperature of 35° C.

Step 3: Curdling the Coconut Milk:—

[0075] Right amount of CaCl.sub.2 and a beneficial bacterial culture of our choice and a beneficial fungi were added to coconut milk and then after prior testing rightly chosen plant rennet namely from Cynara species was added as well. The coagulating and curdling of the milk was reached after 24 hours.

Step 4: Processing and Ripening the Curd:—

[0076] Draining of the curds from whey took 2 hours for runny cheese type, and 12 hours for a moulded cheese type and drained curds were moulded in forms and brined and kept in maturing cabinets. In a separate example, instead of adding mould culture of Penicillium candidum before moulding the curds into form, it was sprayed on the brined cheese curd moulded forms and kept for ripening
Result—Resulting cheese was with very desirable “goat cheese aroma”, taste and texture. Also soft fresh goat cheese type and oozy stretching mozzarella were produced.
In some similar examples, the coconut based vegan cheese was prepared using other plant-origin rennets such as plumeless thistle Carduus acanthoides and European swamp thistle Cirsium palustre. However, the cheese produced was very similar to the cheese produced in example 6.
In some similar examples—The same coconut milk cheese was also produced with other bacterial inclusions such as Brevibacterium linens to produce blue cheese, camembert cheese or Herve type cheese.

Example 7—Production of Vegan Cheese from Avocado Fruit

Step 1: Obtain Rightly Matured Avocado Fruit

[0077] The rightly ripened avocado fruits were collected and then checked for purity. Further, it is assured that no blemished, spoiled, fermented, or contaminated fruit is collected.

Step 2: Prepare Avocado Milk

[0078] The collected avocado was cut-opened and the fruit pulp was collected. The fruit pulp was then blended in a blender with addition of right limited amount of water to form a fruit pulp emulsion The emulsion was then squeezed and filtered to remove any fibrous particle.

Step 3: Curdling the Avocado Milk: —

[0079] The emulsion/avocado milk was heated slowly to 84° C. then cooled down to 30° C., and a right choice of an inorganic salt, a beneficial bacterial culture, and a beneficial fungi were added sequentially. Thereafter, a plant rennet from Cynara species was added to complete the coagulation and curdling occurring for 48 hours.

Step 4: Processing and Ripening the Curd:—

[0080] Draining of the curds from whey took 48 hours and the drained curds were then moulded in forms and ripened in maturing cabinets.
Result—Resulting cheese was a vegan cheese with unique fruity taste and flavour.
In some similar examples—The same avacado cheese was also produced with other bacterial inclusions to produce blue cheese, camembert cheese or Herve type cheese.

Example 8—Production of Vegan Cheese from Durian Fruit

Step 1: Obtain Rightly Ripened Durian Fruit

[0081] The rightly ripened durian fruits were collected and then checked for purity. Further, it is assured that no blemished, spoiled, fermented, or contaminated fruit is collected.

Step 2: Prepare Durian Milk

[0082] Clean ripe durian fruit was cut open and the pericarp along with seed was taken out under clean conditions. The pericarp fleshy pulp was carefully removed from the seed and the pulp was used to make the emulsion/milk for cheese making. The fleshy pulp was blended into fine emulsion/milk form with the use of a blender and addition of sterilised clean water while blending produced the right consistence of the emulsion/milk. The emulsion was heated slowly to 84° C. and then cooled down to 30° C., and then a right choice of inorganic salt and a beneficial bacterial culture and a beneficial fungi were added and followed up by addition of plant rennet from Cynara species. Coagulation and curdling reached after 24 hours for certain durian fruit varieties and after 44 hours in some other durian fruit varieties. Curds were drained from whey for 12 hours and drained curds were moulded in forms and ripened in maturing cabinets. It produced a fruity flavoured but without any trace of strong durian odour cheese with desirable deep orange colour. Also when inoculated with Penicillium Candidum Neige a very attractive pure white rind covered cheese with desirable orange inside cheese colour when cut open.
Same durian cheese was also produced with other bacterial inclusions to produce blue cheese, camembert cheese or Herve type cheese.

Step 3: Curdling the Durian Milk:—

[0083] The emulsion was heated slowly and right choice of inorganic salt and a beneficial bacterial culture and a beneficial fungi were added and followed up by addition of plant rennet from Cynara species. Coagulation and curdling reached after 24 hours in certain durian fruit varieties and after 44 hours in other varieties and curds were drained from whey for 12 hours and drained curds were moulded in forms and ripened in maturing cabinets. Same durian cheese was also produced with other bacterial inclusions to produce blue cheese, camembert cheese or Herve type cheese.

Step 4: Processing and Ripening the Curd:

[0084] Draining of the curds from whey took 12 hours and the drained curds were then moulded in forms and ripened in maturing cabinets.
Result—It produced a fruity flavoured but without any trace of strong durian odour cheese with desirable deep orange colour. Also when inoculated with Penicillium Candidum Neige a very attractive pure white rind covered cheese with desirable orange inside cheese colour when cut open.
In some similar examples—The same durian cheese was also produced with other bacterial inclusions to produce blue cheese, camembert cheese or Herve type cheese.

INDUSTRIAL APPLICABILITY

[0085] The present disclosure relates to a method 100 for preparing a vegan cheese using non-dairy and specifically, a plant based milk. The method 100 assures a complete and a proper coagulation and curdling of non-dairy milk using plant-source rennet which has earlier not been possible. Accordingly, the method provides a truly vegan cheese which is much preferred by the consumers preferring only vegan food products. The vegan cheese of the current invention may be used in preparing cheese of variety of flavors, colors, and for variety of uses in variety of food types. Further, the cheese produced inherits all the desirable properties such as melt, crumble, stretch, firmness, combinations of these, flavor, aroma, and the like, similar to that of the dairy cheese. Additionally, the method while being very easy to follow is much cheaper to execute and thereby providing high quality dairy cheese alternates at much lower prices. Furthermore, the by-products of vegan cheese production, such as vegan whey, left over plant parts of plant origin (example coconut water, coconut shell, kale residue etc.) are used for various food products such as soft drinks, cocktails, flavour enhancers in cuisine and mineral and vitamin supplements in animal feed.

[0086] In another aspect, the present disclosure provides a method 300 for preparing plant based rennet which are able to curdle non-dairy and specifically the plant based milk. Such a method find application wherever the curdling of non-dairy emulsion within in the food industry irrespective of whether being used for cheese formation or not. Again, the rennet is not only vegan but since produced mainly from easily harvestable plant sources, is much cheaper alternative to all other curdling agents. Additionally, the whey produced as a by-product in vegan cheese production can be used to make soft drinks and animal feed supplements. These serve as a much healthier and cheaper alternative to other soft drinks and supplements. Additionally, waste material of vegetables can be upgraded into cheese e.g. leaves and stems of kale can be completely used. Or waste material reaching their THT could be upgraded.
