DETAILED DESCRIPTION OF THE INVENTION

[0026] The present invention relates to a food ingredient, prepared and configured for the preparation of a food product involving an emulsification step using steam.

[0027] The food ingredient may be prepared using an animal product. For example, the ingredient may be prepared using a porcine product, a bovine product, a sheep product, a fish product or a poultry product.

[0028] The animal product used should have animal fat. For example, the animal product should have a minimum fat content of 25%, and may have up to 50% fat content by volume.

[0029] The ingredient may also be prepared using non-animal, vegetable-based products such as peanuts, pistachios, or the like product that contains a substantial amount of fat.

[0030] According to the present invention, the product chosen for the preparation of the ingredient should have the type of fat that can be infused with water using a steam emulsification process as described below.

[0031] In a process according to the first embodiment of the present invention, an ingredient, prepared according to an embodiment of the present invention, is used to make a broth for a traditional Japanese ramen noodle dish, namely Tontoro ramen noodle.

[0032] The ingredient used in the first embodiment is a porcine-based product which is prepared to have the viscosity of a paste at room temperature (25 C.), i.e. a viscosity in the range 80,000-100,000 centipoise.

[0033] Referring to FIG. 1, a method of preparation of a food product according to one embodiment includes placing the ingredient in a receptacle (e.g. a cup) S10, adding soup stock to the ingredient in the receptacle S12 and optionally mixing the two, injecting steam into the mixture S14 to obtain a broth, and adding the broth to other ingredients to obtain a food product S16. The steps S10-S14 set forth in FIG. 1 can be carried out on an on-demand basis (for example, when an order is received from a customer) to make a broth for a single serving.

[0034] To prepare the broth for one serving, for example, 3.5 ounces of the ingredient is added to about six ounces of a chicken soup stock. A suitable chicken stock may be prepared by simmering, for 12 hours, in a 100 quart stock pot, the following:

[0035] 80 lbs (chicken neck, back, breast bones, and some skin)

[0036] 25 L water

[0037] 500 g ginger

[0038] 400 g kombu

[0039] The ingredient and the chicken stock are preferably deposited in, for example, a cup (e.g. a stainless steel frothing pitcher) and mixed gently with a spoon, for example, for less than twenty seconds. Thereafter, steam is used to prepare an emulsion of the ingredient and the chicken stock mixture to obtain a broth. The broth so made can be then mixed with any desired combination of additional ingredients. For example, to prepare Tontoro, the following ingredients may be used: Tare (soy sauce, other flavors), schmaltz (chicken fat, or other rendered animal fats), garlic paste (essentially pureed garlic), scallion, 180 g of noodles, Toppings, such as, menma/bamboo shoots, spinach, chashu pork (pork belly blanched, rolled, sliced, dipped in soy sauce and sugar solution, grilled until char marks form over volcanic rock), and pickled red cabbage. The additional ingredients are added while the broth remains in the heated state (i.e. after emulsification) to make a food product.

[0040] The inventor has discovered that, with an ingredient prepared according to the present invention, the steam from a wand (or spout) of a conventional milk frother can be used to obtain an emulsion suitable for use as a broth in the preparation of a food product as described, under atmospheric pressure, at a relatively low temperature, and in less than a minute. Thus, using an ingredient prepared according to the present invention, one may prepare a broth for a food product on an order by order (on-demand), single serving basis, thereby reducing the amount of potential waste associated with the traditional method and avoiding the opportunity losses associated with the traditional method, when a method according to the present invention is used in a commercial setting (e.g. a restaurant). The amount of ingredient for a single serving may be in the range of 60 grams to 120 grams.

[0041] A steam supplier that can be used (for example, a steam frother called Astra Pro Steamer) in a process according to the present invention produces steam at a relatively low temperature of 212 F./100 C., which is a minimum temperature needed to create steam at 132.26 PSI. The foregoing values are about the average pressure and the average temperature of steam produced by a conventional espresso machine. The steam is not provided at supersonic speed. As a consequence, a broth prepared according to the present invention may be prepared and served in a restaurant environment immediately without concern for safety of the staff and the consumer.

[0042] According to one embodiment of the present invention, the steam supplier may be equipped with a pressure regulator to set the pressure of the steam to a pressure in the range of 50-150 psi, or the preferred range of 90-140 psi. Outside of 50 psi or 150 psi the mixture may not properly emulsify. While the temperature of the broth may vary, the broth prepared according to the present invention needs to reach a minimum temperature of 208.4 F./98 C. to emulsify the paste as the steam moves through the paste. At the minimum temperature, the paste will be fully emulsified under a minute and ready to be used as a broth. If overheated, the fat will leach out of the emulsion. Thus, the temperature should be kept below 212 F./100 C. and above 208.4 F./98 C. to ensure that the fat will remain within the emulsion.

[0043] According to another embodiment of the present invention, the steam supplier may be equipped with a steam supply rate regulator to permit reducing or increasing the rate of supply (i.e. speed) of the steam to the mixture. The rate of the supply of steam can be used to adjust the degree of emulsification that can be achieved under a minute on an order-by-order (on-demand) basis.

[0044] Thus, a steam supplier as discussed can allow for the control of steam temperature and steam speed to vary the quality of the broth.

[0045] The steam may be supplied via a tube or a wand inserted into the mixture, which is retained in an open-mouth receptacle (e.g. a cup).

[0046] Referring to FIG. 2, an ingredient suitable for making a broth on-demand can be prepared based on an animal product, for example, a porcine product. The animal product may be first pressure cooked S20. The pressure-cooked animal product is then pulverized (chopped) S22 to obtain a paste. The pulverized (chopped) pressure-cooked product is then chilled S24. The chilled, pulverized, pressure-cooked animal product is then packaged S26.

[0047] An ingredient according to the first embodiment may be based on a porcine product and is prepared by pressure cooking 11 kg of pork belly (with the skin on) in 2.3 kg of water at 15 psi of pressure. As the pork belly, Berkshire pork belly (with the skin on) may be used. After the cooking step, the fat is rendered out of the pressure-cooked pork belly and the pressure-cooked product is pulverized (chopped finely) into a paste-like mass. An All-Clad K275OD may be used to pulverize/chop the pressure-cooked pork belly in two minutes. The paste so obtained is then chilled for one hour. To chill the paste, the paste is placed in a water-cooled chiller apparatus, while being mixed, for example, with a SAKI Automatic Pot Mixer (a conventional pot mixer) on high speed, whereby the paste may be homogenized.

[0048] Referring to FIG. 3, the chiller apparatus may include a receptacle 10 that receives the paste 12, which is water-cooled using, for example, running water 14 supplied around the exterior surface 16 of the wall 18 of the receptacle 10. For this purpose, the receptacle may be placed in another receptacle 20, bucket or tub, and running water 14 may be supplied to the space 22 between the receptacle 10 that contains the paste 14 and the interior wall 24 of the receptacle 20 in which the receptacle 10 is received. The water may be provided to space 22 via an input pipe 26 and extracted via an output pipe 28 to keep the water moving to ensure that the temperature of the cooling water remains substantially the same in the temperature range of 40-50 F. The paste must be cooled from 120 F. to 70 F. in less than two hours, and must be cooled from 70 F. to 45 in less than an additional four hours. The temperature of the running water may be 4.5 C./40 F. in the winter, 7 C./50 F. in the summer, which may depend upon the location of the available water (reservoir vs. aquifer and even the distance from the equator). Once cooled, the paste may be deposited into smaller containers and kept cold in a freezer. Also, conventional preservatives may be added to the paste as required before packing. In one preferred embodiment, the paste may be packaged for preparation of a single serving. The amount of paste for a single serving may be in the range 60 grams to 120 grams. The preferred minimum amount of paste for a single serving may be at a minimum 100 g and at a maximum 120 g. Optionally, the single serving package may be hermetically sealed to improve its shelf life. Optionally, the paste may be pasteurized using any suitable method. A suitable packaging, for example, may be a flexible, squeezable packet made of a plastic or metallic foil typically used for a single serving of salad dressing.

[0049] Although the present invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. It is preferred, therefore, that the present invention be limited not by the specific disclosure herein, but only by the appended claims.
