[0034] A method for preparing legumes powder using aquafaba (for example, soaking liquid (AQ)) according to various embodiments of the present invention may be a combination of one or more preparation methods of legumes soaking liquid (AQ) powder developed in various alternative foods, wherein by preparing legumes soaking liquid (AQ) powder through a pre-soaking treatment process or a pre-soaking non-treatment process of legumes (1), the legumes soaking liquid (AQ) powder obtained through this process may be used in various vegetable vegan dishes and may also be used as a variety of alternative foods such as plant-based meat, cultured meat, and artificial eggs that may replace animal protein.

[0035] The term aquafaba (soaking liquid (AQ)) is a compound word of aqua (water)+faba (soybean), and refers to thick translucent liquid obtained by boiling legumes such as chickpeas in water. However, this cooking liquid is usually discarded after food preparation. Accordingly, the aquafaba may be formed into a stable edible foam with emulsifying ability with functional properties that may replace eggs in vegan cuisine, confectioneries and baking.

[0036] First, in an embodiment of the present invention, the process of preparing a legume powder through the pre-soaking treatment process of a method of preparing the legume soaking liquid (AQ) powder will be described as follows.

[0037] FIG. 1 is a drawing showing a pre-soaking treatment process in a method for preparing legumes powder using aquafaba (for example, soaking liquid (AQ)) according to various embodiments of the present invention, and FIG. 2 is a flow chart showing a pre-soaking treatment process in a method for preparing legumes powder using aquafaba (for example, soaking liquid (AQ)) according to various embodiments of the present invention.

For example, the legumes (1) may include chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d). In addition, the legumes (1) may include at least one of chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), or small black soybeans (1d). Here, the chickpeas (1a) are foreign beans from Canada, and the yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) are domestic beans.

[0039] In this embodiment, the legumes (1) will be described by selecting chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) (S1).

[0040] The legumes (1) include, for example, chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) but are not limited thereto. For example, the legumes may be applied in various ways as long as they are beans that may prepare legumes soaking liquid (AQ) powder.

[0041] The selected chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) may be washed with distilled water (B1) and then dried at room temperature of 22? C. (S2).

[0042] The chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) may be pre-soaked in distilled water (B1) at 4? C. for 16 hours (S3). For example, the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) may be soaked in distilled water (B1) at 4? C. for 16 hours.

[0043] At this time, the chickpeas (1a) may be placed in a first glass jar (10) and sealed, and the yellow soybeans (1b) may be placed in a second glass jar (20) and sealed. In addition, the large black soybeans (1c) may be placed in a third glass jar (30) and sealed, and the small black soybeans (1d) may be placed in a fourth glass jar (40) and sealed.

[0044] At this time, the chickpeas (1a) and distilled water (B1) may be contained in the first glass jar (10) at a 1:4 ratio. In this state, the chickpeas (1a) may be pre-soaked in the distilled water (B1) at 4? C. for 16 hours (S3).

[0045] The yellow soybeans (1b), the large black soybeans (1c) and the small black soybeans (1d) and distilled water (B1) may be contained in each of the second, third and fourth glass jars (20, 30, and 40) at a ratio of 1:3. In this state, the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) may be pre-soaked in the distilled water (B1) at 4? C. for 16 hours (S3).

[0046] In addition, the soaked chickpeas (1a), yellow soybeans (1b), large black soybeans (1c) and small black soybeans (1d), and soaking liquids (1a-1, 1b-1, 1c-1 and 1d-1) may be separated using a strainer (A1) (S4).

[0047] Distilled water (B1) may be added to the first, second, third, and fourth glass jars (10, 20, 30, and 40) containing the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) separated from the soaking liquids (1a-1, 1b-1, 1c-1, and 1d-1) at a ratio of 1:1 (w/w).

[0048] In this state, the first, second, third and fourth glass jars (10, 20, 30, and 40) containing the pre-soaked chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) and distilled water (B1) may be placed in a pressurizing/heating device (A2) for heating and pressurizing.

[0049] These first, second, third and fourth glass jars (10, 20, 30, and 40) may be heated at 118? C. while being pressurized by a pressurizing/heating device (A2) (for example, a pressure cooker).

[0050] At this time, the pre-soaked chickpeas (1a) may be cooked by heating for 30 minutes while being pressurized at 70 to 80 kPa by the pressurizing/heating device (A2), and the pre-soaked yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) may be cooked by heating for 90 minutes while being pressurized to 70 to 80 kPa by the pressurizing/heating device (A2) (S5).

[0051] The chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) cooked by heating can be cooled using a cooling device (A3) at 22? C. for 24 hours (S6).

[0052] The cooled chickpeas (1a), yellow soybeans (1b), large black soybeans (1c) and small black soybeans (1d), and soaking liquids (1a-2, 1b-2, 1c-2, and 1d-2) may be separated using a strainer (A1) (S7). For example, the soaking liquids (1a-2, 1b-2, 1c-2, and 1d-2) may be separated from the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) using a strainer (A1).

[0053] The soaking liquids (1a-2, 1b-2, 1c-2, and 1d-2) (for example, aquafaba, AQ) of the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) separated in this way may be vacuum dried for 48 hours in a dryer (A4) after complete freezing at ?20? C. (S8).

[0054] When drying of the soaking liquids (1a-2, 1b-2, 1c-2, and 1d-2) (for example, aquafaba, AQ) of the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d) is completed, the chickpea soaking liquid (AQ) powder (1a-3), yellow soybean soaking liquid (AQ) powder (1b-3), large Small black soybean soaking liquid (AQ) powder (1c-3), and Small black soybean soaking liquid (AQ) powder (1d-3) may be obtained from the soaking liquids (1a-2, 1b-2, 1c-2, and 1d-2) (for example, aquafaba, AQ) (S9).

[0055] In this way, the chickpeas (1a), the yellow soybeans (1b), the large black soybeans (1c), and the small black soybeans (1d), which are selected legumes (1), are washed with distilled water (B1), dried, and pre-soaked, the pre-soaked legumes (1) and soaking liquid are separated, the separated legumes are pressurized, heated, and cooled, and the cooled legumes (1) and the soaking liquid are separated, and the separated soaking liquid is dried to prepare chickpea soaking liquid (AQ) powder (1a-3), yellow soybean soaking liquid (AQ) powder (1b-3), large Small black soybean soaking liquid (AQ) powder (1c-3), and Small black soybean soaking liquid (AQ) powder (1d-3), and the chickpea soaking liquid (AQ) powder (1a-3), the yellow soybean soaking liquid (AQ) powder (1b-3), the large Small black soybean soaking liquid (AQ) powder (1c-3), and the Small black soybean soaking liquid (AQ) powder (1d-3) obtained through the processes may be used in or added to a variety of dishes such as porridge, soup, stew, rice cakes, vegetable pancakes, mung-bean pancakes, noodles, snacks, breads, soybean paste, makjang and red pepper paste and also used as plant-based meat, cultured meat, and artificial eggs to replace animal protein. Therefore, the chickpea soaking liquid (AQ) powder (1a-3), the yellow soybean soaking liquid (AQ) powder (1b-3), the large Small black soybean soaking liquid (AQ) powder (1c-3), and Small black soybean soaking liquid (AQ) powder (1d-3) may also be used as a meat substitute for vegetarians and users with allergies to animal proteins.

[0056] In various other embodiments of the present invention, the process of preparing legumes soaking liquid (AQ) powder through a pre-soaking non-treatment process of a preparation method of the legumes soaking liquid (AQ) powder will be described as follows.

[0057] FIG. 3 is a drawing showing a pre-soaking non-treatment process in a method of preparing legumes soaking liquid (AQ) powder according to various other embodiments of the present invention, and FIG. 4 is a flow chart showing a pre-soaking non-treatment process in a method of preparing legumes soaking liquid (AQ) powder according to various embodiments of the present invention.

[0058] Referring to FIGS. 3 and 4, in the method of preparing legumes soaking liquid (AQ) powder, first, legumes (10) may be selected. For example, the legumes (10) may include chickpeas (10a), yellow soybeans (10b), large black soybeans (10c), and small black soybeans (10d). In addition, the legumes (10) may include at least one of chickpeas (10a), yellow soybeans (10b), large black soybeans (10c), or small black soybeans (10d).

[0059] In this embodiment, the legumes (10) will be described by selecting chickpeas (10a), yellow soybeans (10b), large black soybeans (10c), and small black soybeans (10d) (S10).

[0060] The selected chickpeas (10a), yellow soybeans (10b), large black soybeans (10c) and small black soybeans (10d) may be washed with distilled water (B1) and then dried at room temperature of 22? C. (S20).

[0061] Next, the chickpeas (10a) may be placed in a first glass jar (11) and sealed, and the yellow soybeans (10b) may be placed in a second glass jar (21) and sealed. In addition, the large black soybeans (10c) may be placed in a third glass jar (31) and sealed, and the small black soybeans (10d) may be placed in a fourth glass jar (41) and sealed.

[0062] At this time, the chickpeas (10a) and distilled water (B1) may be contained in the first glass jar (11) at a 1:1.5 (w/w) ratio. Similarly, the yellow soybeans (10b), the large black soybeans (10c) and the small black soybeans and distilled water (B1) may be contained in each of the second, third and fourth glass jars (21, 31, and 41) at a 1:1.5 (w/w) ratio.

[0063] In this state, the first, second, third and fourth glass jars (11, 21, 31, and 41) containing the chickpeas (10a), the yellow soybeans (10b), the large black soybeans (10c), and the small black soybeans (10d) and distilled water (B1) may be placed in a pressurizing/heating device (A2) for pressurizing and heating.

[0064] The first, second, third and fourth glass jars (11, 21, 31, and 41) may be heated at 118? C. while pressurizing by a pressurizing/heating device (A2).

[0065] At this time, the chickpeas (10a) may be cooked by heating for 90 minutes while being pressurized to 70 to 80 kPa by the pressurizing/heating device (A2). Likewise, the yellow soybeans (10b), the large black soybeans (10c), and the small black soybeans (10d) may be cooked by heating for 90 minutes while being pressurized to 70 to 80 kPa by the pressurizing/heating device (A2) (S30).

[0066] The chickpeas (10a), the yellow soybeans (10b), the large black soybeans (10c), and the small black soybeans (10d) cooked by heating may be cooled using a cooling device (A3) at 22? C. for 24 hours (S40).

[0067] The cooled chickpeas (10a), yellow soybeans (10b), large black soybeans (10c) and small black soybeans (10d), and soaking liquids (10a-1, 10b-1, 10c-1, and 10d-1) (for example, aquafaba, AQ) may be separated using a strainer (A1) (S50).

[0068] The soaking liquids (10a-1, 10b-1, 10c-1, and 10d-1) (for example, aquafaba, AQ) of the separated chickpeas (10a), yellow soybeans (10b), large black soybeans (10c), and small black soybeans (10d) may be vacuum dried for 48 hours in a dryer (A4) after complete freezing at ?20? C. (S60).

[0069] When drying of the soaking liquids (10a-1, 10b-1, 10c-1, and 10d-1) (for example, aquafaba, AQ) of the chickpeas (10a), the yellow soybeans (10b), the large black soybeans (10c), and the small black soybeans (10d) is completed, chickpea soaking liquid (AQ) powder (10a-2), yellow soybean soaking liquid (AQ) powder (10b-2), large Small black soybean soaking liquid (AQ) powder (10c-2), and Small black soybean soaking liquid (AQ) powder (10d-2) may be obtained from the soaking liquids (10a-1, 10b-1, 10c-1, and 10d-1) (S70).

[0070] In this way, the chickpeas (10a), the yellow soybeans (10b), the large black soybeans (10c), and the small black soybeans (10d), which are selected legumes (10), are washed with distilled water (B1), then dried, pressurized, heated, and cooled, and the cooled legumes (10) and the soaking liquid (for example, aquafaba, AQ) are separated, and the separated soaking liquid (for example, aquafaba, AQ) is dried to prepare chickpea soaking liquid (AQ) powder (10a-2), yellow soybean soaking liquid (AQ) powder (10b-2), large Small black soybean soaking liquid (AQ) powder (10c-2), and Small black soybean soaking liquid (AQ) powder (10d-2), and the chickpea soaking liquid (AQ) powder (10a-2), the yellow soybean soaking liquid (AQ) powder (10b-2), the large Small black soybean soaking liquid (AQ) powder (10c-2), and the Small black soybean soaking liquid (AQ) powder (10d-2) obtained through the processes may be used in a variety of vegan dishes and used as plant-based meat, cultured meat, and artificial eggs to replace animal protein. Therefore, the chickpea soaking liquid (AQ) powder (10a-2), yellow soybean soaking liquid (AQ) powder (10b-2), large Small black soybean soaking liquid (AQ) powder (10c-2), and Small black soybean soaking liquid (AQ) powder (10d-2) may also be used as a meat substitute for vegetarians and users with allergies to animal proteins.

[0071] According to various embodiments, legumes soaking liquids (AQ) (for example, chickpea soaking liquid (1a-2), yellow soybean soaking liquid (1b-2), large Small black soybean soaking liquid (1c-2), and Small black soybean soaking liquid (1d-2)), which are produced by pre-soaking the legumes (1) in water before cooking, may achieve excellent performance in both analyses of foaming ability and emulsifying ability compared to legumes soaking liquids (for example, chickpea soaking liquid (10a-1), yellow soybean soaking liquid (10b-1), large Small black soybean soaking liquid (10c-1), and Small black soybean soaking liquid (10d-1)) produced through pre-soaking non-treatment of the legumes (10). In particular, the soaking liquid (1a-2) prepared from chickpeas (1a) used in pre-soaking was able to show superior emulsifying ability compared to other soybean soaking liquids, but the soaking liquid (for example, aquafaba) of other soybean samples showed emulsification stability of 80% or more. In addition, the soybean soaking liquids (yellow soybean soaking liquid (1b-2), large Small black soybean soaking liquid (1c-2), and Small black soybean soaking liquid (1d-2)) used in the pre-soaking showed excellent foaming ability compared to foreign chickpea soaking liquid (1a-2) from Canada, known as the control for aquafaba.

[0072] As shown in FIG. 5, the chickpea soaking liquid (1a-2), the yellow soybean soaking liquid (1b-2), the large Small black soybean soaking liquid (1c-2), and the Small black soybean soaking liquid (1d-2) separated using a strainer after pre-soaking may be whipped for 2 minutes using a hand mixer (for example, a whisk). The white of one egg may be replaced with about 30 mL of the whipped chickpea soaking liquid (1a-2), yellow soybean soaking liquid (1b-2), large Small black soybean soaking liquid (1c-2), and Small black soybean soaking liquid (1d-2).

[0073] As such, the legumes soaking liquid (AQ) powder (chickpea powder (1a-3), yellow soybean powder (1b-3), large Small black soybean powder (1c-3), and Small black soybean powder (1d-3)) respectively prepared using the legumes chickpeas (1a), yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d) is expected to be used to develop new high-value functional foods made from legumes with added flavor and nutrition to counter the nutritional imbalance in vegan food, which is expected to help recover food resources and prevent environmental pollution.

[0074] For example, the soaking liquid (for example, aquafaba), which is a legumes liquid in which the legumes are boiled, is a highly nutritious, high-protein, water-soluble by-product in which various bioactive components of raw legumes have been eluted, and its potential for recycling as a food material is currently attracting attention as an upcycled food. It is believed that this will help recover food resources and prevent environmental pollution instead of discarding the soaking liquid. In addition, legumes cooking water (for example, aquafaba, AQ), which is a soaking liquid (for example, waste liquid), shows great potential as a cost-effective substitute for eggs in vegan cuisine, confectioneries and baking. For example, legumes powder produced through this soaking liquid (for example, aquafaba, AQ) may be provided as an egg substitute for vegetarians. Therefore, we can expect the expansion of the development of highly useful vegetable raw material foods along with meat substitutes.

[0075] For example, currently, soybeans (examples of soybeans: yellow soybeans (1b), large black soybeans (1c), and small black soybeans (1d)), which are attracting attention as a meat substitute in the vegan market, include not only high-quality protein but also various biologically active substances such as isoflavones, saponins, plant sterols, and peptides, and some of these compounds help relieve symptoms of hypocholesterolemia, atherosclerosis, lowering the risk of cancer, high blood pressure, and osteoporosis, as well as menopausal symptoms. Despite the efficacy of soybeans, soybeans in the Asian diet are limited to tofu and soy sauce and soybean paste made by fermenting soybeans. Therefore, it is advantageous to develop and distribute products that utilize the excellent components of soybeans in a more diverse manner.
