DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention sets forth an alternative protein-based vegetable crop product with high nutrients, fiber and protein content, that can be shaped into a patty with an unanticipated chewy vegetable specific texture, superior taste, that is made without GMO ingredients. The yardlong bean is used as the raw ingredient in the present invention. This green bean is classified as a vegetable crop and it is distinguished from many other legumes and pluses already used for making burger patties. The entire vegetable including the enclosing the pods is utilized. It will be appreciated that other products can be derived using other vegetable crop varieties and alternative methods in accordance with this invention. Variety crops such as runner bean (Phaseolus coccineus) and hyacinth bean (Lablab purpureus) or a combination of vegetable crops can be used to make similar products. The description below illustrates the principles of the invention.

[0025] Yardlong Bean Product:

[0026] There are many replicated meat products that have been made by forming texturized vegetable protein (mostly grain or legume) and isolates. Such products use soy and pea protein mixed with plant-flour in a mechanical extrusion process to obtain a meat-like texture when they are rehydrated and cooked. The problem with these products is that they are highly processed, and the proteins are modified—even though soy, for instance, is considered a nutritious food that contains the eight essential amino acids that are required for human nutrition. But, depending on the process used, it is a well-known fact that key nutrients in vegetables are significantly reduced when subjected to heat. Therefore, slow cooking times and low temperatures are highly recommended when processing plant-based ingredients. This invention takes nutritional factors into account and so less processing and less heat is used to provide a healthier product.

[0027] The Process and Procedure:

[0028] Reference is made to the process flow diagram (100) as shown in FIG. 1; the manufacturing process as illustrated in FIG. 2; and a profile view is illustrated in FIG. 3 of the final product in associated with the invention.

[0029] A low heat process is preferred for the preservation of naturally found nutrients, protein and minerals in the vegetable crop.

[0030] 1. Preparation of Vegetable Ingredients:

[0031] The first step involves mechanically processing the fresh raw ingredients (101) by using a food processor (HAMILTON BEACH 12-Cup Stack & Snap™ Food Processor with Big Mouth, Black & Stainless MODEL: 70725) with the S-Blade. The vegetable is processed on the chop setting to yield pieces of 1-3 mm in length.

[0032] 2. Blanching:

[0033] The finely chopped yardlong bean vegetable is blanched at 248 deg F for no more than approximately 1-2 minutes. The liquid to solids ratio is approximately 1 part of water to 50 parts of solids. This step is performed in order to breakdown the fibers and improve digestibility. This pre-conditioning step (102) is also conducted to activate organic binders and initiate settings for texturization in the final product. The time, temperature and volume of water would vary depending on the mass of the mixture. It was discovered that the texture of the final product is a function of time and temperature.

[0034] 3. Seasoning:

[0035] Fresh whole plant herbal aromatics are processed 101 and are added to evenly distribute the flavor (103) in the mixture. The internal heat from process 102 is utilized by using heat transfer—the flavor of the herbs is released as it is taken up by the yardlong bean mixture. The seasoning is added in 1:1 ratio by mass of the total composition.

[0036] 4. Binding

[0037] Organic flour is used as a binder; it is added to the mixture (104) in a ratio of approximately 1-2% by weight of the total wet mixture. The composition is well mixed 104 until a homogenous “sticky” consistency is formed.

[0038] 5. Extruding

[0039] The mixture is loaded on a patty molding press (105) machine (Eurodib HF100 Manual Hamburger Patty Molding Press with Single-Level Press Handle) as a portion control mechanism. The mold unit 105 ensures that each patty is precisely 102 mm in diameter and 57 g in weight. No heat or pressure treatment are required in the process.

[0040] 6. Shaping and Frying

[0041] The patty is fried in a preheated pan-fryer (106) at 332-345 deg F in refined oils such as peanut oil or sunflower oil. These temperatures are necessary to create a crust on the patty as soon as it hits the fryer. This seals the outsides, preventing the insides from absorbing too much oil. Additionally, these oils are preferred because they have a much higher smoke point of almost 500 deg F and can withstand higher temperatures without releasing harmful compounds, including carcinogenic, cancer-causing free radicals. The patty is shaped as it is fried 106 for about 4-5 minutes while flipping every 2 mins until it turns from green-to-brown. The cooked patties have the appearance of a beef patty but with superior flavor and aroma to conventional meat.

[0042] 7. Cooling and Freezing

[0043] The cooked patties are placed on a cooling rack (107). The patties could either be used right away or could be frozen until ready to be eaten. The long product shelf life of the cooked patty is achieved without the use of artificial preservatives. The taste remained intact by freezing (108).

[0044] 8. Packing

[0045] The frozen product is packed (109) in a sealed container, stored and shipped. The product is held in a frozen state until ready to be eaten. When ready to be eaten, the patty is removed from the freezer and placed directly into a preheated oven (110) until heated to an internal temperature of 160 deg F. This step is critical in restoring the patty to its original state as when it was freshly made.

[0046] The Manufacturing Process:

[0047] Reference is made to the schematic diagram shown in FIG. 2 illustrating the layout of the manufacturing production (200) in accordance with the invention. A food processor unit which is not shown is used to chop the yardlong bean. A chamber (201) with time, temperature (203) and pressure (202) controls is used to perform the preprocessing step. Mixing is conducted by using a food paddle mixer (204) and then the mixture is received by an extruder (205). A pan-fryer (206) with temperature (208) controls is used to cook the extruded portions. The patty is shaped (207) while frying 206. Cooling racks (209) are used to allow the patties to cool at room temperature, before putting to freeze (210). Depending on the facility the product could be packaged before it is frozen until time for shipment and distribution.

[0048] The Burger Assembly:

[0049] FIG. 3 illustrates an example of an assembled yardlong (300) plant-based protein alternative WPBF product in accordance with the invention. The plant-based burger patty (303) is paired with whole grain+flax bread (305) from local artisan baker Atwater's. It is layered with a slice of avocado (304), followed by a patty 303. On top of the patty 303 is a thick juicy slice of heirloom tomato (302), and it's nutritiously balanced with a generous serving of alfalfa or pea shoot sprouts (301). As an option, a layer of melted plant-based cheese could be added for a more traditional style burger.
