Abstract
Description
[Technical Field]
[0001] The present invention relates to an oil and fat composition for cooked rice and a cooked rice food product. [Background technology]
[0002] Rice foods such as fried rice and pilaf are preferred for their freshly cooked, flaky texture. Convenience stores and supermarkets are selling pre-cooked rice foods that can be easily heated in a microwave oven, and demand for these foods has been increasing in recent years due to factors such as an increase in dual-income households and small households. However, the flaky texture of freshly cooked rice tends to be lost over time, resulting in a sticky texture. Reheating rice in a microwave oven does not improve this sticky texture. Therefore, there is a need for technology that can maintain the flaky texture of freshly cooked rice.
[0003] To date, techniques for coating the surface of rice grains with oils and various emulsifiers have been investigated as a method for maintaining a flaky texture. In most cases, the focus has been on uniformly coating the surface of the rice grains, and oils that are liquid at room temperature, such as highly fluid rapeseed oil or soybean oil, have generally been used. While this has been effective in maintaining a flaky texture to a certain extent, a large amount of oil must be used to achieve a uniform coating, which can make the rice feel oily when eaten. Furthermore, oils that are liquid at room temperature remain fluid even in the chilled temperature range, and therefore tend to drip from the rice grains during storage. This reduces the amount of oil that adheres to the rice grains when eaten, reducing the flaky texture, or they can accumulate at the bottom of the container, resulting in an unsightly appearance.
[0004] Patent Document 1 discloses a technique for improving the loosening properties of no-wash rice by adhering an oil or fat composition that is solid at 15°C and contains 10 to 100% by mass of linear saturated fatty acids having 10 to 12 carbon atoms among the constituent fatty acids of the oil or fat to the surface of the rice. While this technique is effective in maintaining the fluffy texture of cooked rice to a certain extent, when cooking cooked rice with ingredients, such as in fried rice, the amount of oil or fat composition adhering to the rice grains may decrease, making the rice less fluffy.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-93842 Summary of the Invention [Problem to be solved by the invention]
[0006] In view of the above problems, we have been studying oil and fat compositions for cooked rice that can coat the surface of rice to impart a light and fluffy texture to the rice, and that do not feel oily when eaten. The object of the present invention is to provide an oil and fat composition for cooked rice that can prepare cooked rice foods that maintain a light and fluffy texture while not feeling oily. [Means for solving the problem]
[0007] As a result of extensive research to solve the above problems, the present inventors have discovered that a cooked rice food product that maintains a flaky texture while not feeling oily can be prepared by using an oil and fat composition for cooked rice containing specific amounts of specific oils and fats and emulsifiers, and have thus completed the present invention.

Even more preferably, the present invention relates to the oil-and-fat composition for cooked rice described above, which is a water-in-oil emulsified composition. A second aspect of the present invention relates to a cooked rice food product in which 0.5 to 10 parts by weight of the above-described oil and fat composition for cooked rice is mixed with 100 parts by weight of cooked rice. A third aspect of the present invention relates to a method for producing an oil and fat composition for cooked rice, in which the entire oil and fat composition for cooked rice contains 50 to 99% by weight of oils and fats and 0.1 to 11% by weight of an emulsifier, the melting point of the entire oil and fat is 29 to 38°C, and the SFC at 35°C of the entire oil and fat is 1.5 to 13%, the method comprising a step of mixing the oil and fat and the emulsifier.

[Effects of the Invention]
[0009] According to the present invention, it is possible to provide an oil and fat composition for cooked rice that can be used to prepare cooked rice foods that maintain a light and fluffy texture while not feeling oily. DETAILED DESCRIPTION OF THE INVENTION
[0010] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments. The oil and fat composition for cooked rice according to this embodiment contains specific amounts of oils and fats with melting points and SFCs within specific ranges, and an emulsifier. This oil and fat composition for cooked rice allows for the preparation of cooked rice foods that maintain a light, fluffy texture while not feeling oily, and is therefore suitable for use in cooked rice foods that are intended to be eaten some time after cooking. Here, "cooking by heating" refers to any method of cooking food by applying heat to ingredients, and is not particularly limited as long as it is a cooking method that raises the temperature of the ingredients, and examples of cooking methods that can be used include baking, simmering, steaming, boiling, stir-frying, cooking rice, frying, and smoking.
[0011] (Oils and fats) The fats and oils contained in the fat and oil composition for cooked rice are not particularly limited as long as the melting point of the entire fat and oil is 29 to 38°C and the SFC at 35°C of the entire fat and oil is in the range of 1.5 to 13%.
[0012] The melting point of the entire oil and fat is preferably 31 to 37°C, more preferably 33 to 36°C. If the melting point of the entire oil and fat is below 29°C, the oil and fat may run off the rice during storage of the cooked rice food, or the rice may not feel sufficiently crispy. If the melting point of the entire oil and fat exceeds 38°C, the cooked rice food may feel oily when eaten. In the present disclosure, the term "crispy" refers to a state in which the rice grains contained in the cooked rice food do not adhere well to each other, to other optionally contained foods, or to the rice and other optionally contained foods contained in the cooked rice food, and the rice as a whole is moderately loosened. In the present disclosure, the term "oily" refers to the sensation of oil and fat clinging to the mouth when eating the cooked rice food.
[0013] The melting point of the entire fat or oil can be measured in accordance with "Standard Test Methods for Analysis of Fats, Oils, and Related Materials 2.2.4.2 (1996) 1996 Edition, Established by the Japan Oil Chemists' Society."
[0014] The SFC at 35°C of the entire fat or oil is preferably 2.0 to 7.0%, more preferably 3.5 to 5.5%. If the SFC at 35°C of the entire fat or oil is less than 1.5%, the cooked rice food may not feel sufficiently crispy when eaten. If the SFC at 35°C of the entire fat or oil is more than 13%, the cooked rice food may feel oily when eaten.
[0015] The SFC can be measured according to the measurement method of "2.2.9-2003 Solid Fat Content (NMR Method)" in "Standard Test Methods for the Analysis of Fats, Oils and Related Materials" compiled by the Japan Oil Chemists' Society. The SFC requirement needs to be satisfied by all of the fats and oils contained in the oil-in-water emulsified fat composition, and when multiple types of fats and oils are used, the SFCs of the individual fats and oils are not particularly limited.
[0016] The content of the oil / fat in the entire oil / fat composition for cooked rice may be 50 to 99% by weight, preferably 65 to 95% by weight, and more preferably 80 to 90% by weight. If the content of the oil / fat is less than 50% by weight, the cooked cooked rice food may not feel sufficiently flaky when eaten. If the content of the oil / fat is more than 99% by weight, the cooked cooked rice food may feel oily or may not feel sufficiently flaky when eaten.
[0017] The type of oil or fat is not particularly limited as long as it is an edible oil or fat, and examples thereof include vegetable oils and fats such as palm oil, palm kernel oil, coconut oil, rapeseed oil, hyercin rapeseed oil, corn oil, cottonseed oil, soybean oil, sunflower oil, safflower oil, and olive oil; animal oils and fats such as milk fat, beef tallow, lard, and fish oil; and those which have been processed by hardening, fractionation, interesterification, or the like; and at least one selected from these groups can be used.
[0018] It is particularly preferred to use a suitable combination of multiple types of oils and fats so as to satisfy the melting point and SFC values described above. Examples of suitable oil and fat combinations include interesterified palm oil and coconut oil, and interesterified rapeseed oil, palm oil, and coconut oil.
[0019] (emulsifier) The emulsifier contained in the oil and fat composition for cooked rice is not particularly limited as long as it is generally used in foods and approved for use as a food additive. Examples include glycerin fatty acid esters, glycerin organic acid fatty acid esters, polyglycerin fatty acid esters, polyglycerin condensed ricinoleic acid esters, sorbitan fatty acid esters, sucrose fatty acid esters, propylene glycol fatty acid esters, polyoxyethylene sorbitan fatty acid esters, lecithin (soybean lecithin, sunflower lecithin, egg yolk lecithin, etc.), enzymatically hydrolyzed lecithin (soybean lysolecithin, egg yolk lysolecithin, etc.). Among these, from the viewpoint of imparting a better flaky texture to cooked cooked rice foods when eaten, at least one selected from the group consisting of glycerin fatty acid esters, sucrose fatty acid esters, sorbitan fatty acid esters, propylene glycol fatty acid esters, and lecithin is preferred, and at least one selected from the group consisting of glycerin fatty acid esters and sucrose fatty acid esters with an HLB of 8 or higher is more preferred.
[0020] The content of the emulsifier in the oil and fat composition for cooked rice may be 0.1 to 11 wt %, preferably 0.5 to 7 wt %, and more preferably 2 to 5 wt %, of the total oil and fat composition for cooked rice. If the content of the emulsifier is less than 0.1 wt %, the cooked cooked rice food may not have a sufficiently fluffy texture when eaten. If the content of the emulsifier is more than 11 wt %, the cooked cooked rice food may have a poor flavor due to the emulsifier being more noticeable when eaten, or the cooked cooked rice food may be more likely to feel oily when eaten.
[0021] The fat and oil composition for cooked rice is preferably an emulsified composition containing water, particularly when it contains a sucrose fatty acid ester with an HLB of 8 or more, and may be either a water-in-oil emulsified composition or an oil-in-water emulsified composition, but is more preferably a water-in-oil emulsified composition from the viewpoint of imparting a better fluffiness.
[0022] When the fat and oil composition for cooked rice is a water-in-oil emulsion composition or an oil-in-water emulsion composition, it is sufficient that the emulsifier is contained in at least one of the oil phase and the aqueous phase, and it is preferable that the emulsifier is contained in both the oil phase and the aqueous phase. Note that the emulsifier is contained in the oil phase if it is lipophilic, or in the aqueous phase if it is hydrophilic.
[0023] A lipophilic emulsifier means an emulsifier that dissolves or disperses in oil, and a hydrophilic emulsifier means an emulsifier that dissolves or disperses in water. HLB is used as a measure of the lipophilicity and hydrophilicity of an emulsifier, and the HLB of a lipophilic emulsifier is approximately 0 to 9, while the HLB of a hydrophilic emulsifier is approximately 7 to 20. However, the lipophilicity and hydrophilicity are not determined solely by the HLB.
[0024] When the oil and fat composition for cooked rice is an emulsified composition containing water, the content of water in the oil and fat composition for cooked rice is preferably 1 to 50% by weight, more preferably 5 to 40% by weight, and even more preferably 10 to 30% by weight, of the entire oil and fat composition for cooked rice, from the viewpoint of stabilizing the emulsion of the oil and fat composition for cooked rice.
[0025] (Optional raw materials) The fat and oil composition for cooked rice may contain, as optional ingredients, food ingredients or food additives such as flavorings, colorings, antioxidants, pH adjusters, thickening stabilizers, sugars, salt, sweeteners, acidulants, spices, flavoring materials, dairy ingredients, etc. If the optional ingredient is a lipophilic ingredient, it is contained in the oil phase, and if it is a hydrophilic ingredient, it is contained in the aqueous phase.

[0038] (Manufacturing method) An embodiment of the method for producing the oil and fat composition for cooked rice will be exemplified below. One embodiment relates to a method for producing an oil and fat composition for cooked rice, in which the entire oil and fat composition contains 50 to 99% by weight of oil and fat, and 0.1 to 11% by weight of an emulsifier, the melting point of the entire oil and fat is 29 to 38°C, and the SFC at 35°C of the entire oil and fat is 1.5 to 13%, and the production method includes a step of mixing the oil and fat and the emulsifier.
[0039] The fat and oil, the emulsifier, and optionally other raw materials (e.g., lipophilic raw materials) are mixed together. The fat and oil are preferably melted in advance. The temperature at which the fat and oil are melted may be 60 to 90°C, and the temperature at which the oil phase mixture is stirred may be maintained at 60 to 80°C.
[0040] Furthermore, when the oil and fat composition for cooked rice is an emulsified composition containing water, one embodiment of the method for producing the oil and fat composition for cooked rice comprises 50 to 99% by weight of oils and 0.1 to 11% by weight of an emulsifier in the entire oil and fat composition, the melting point of the entire oil and fat is 29 to 38°C, and the SFC at 35°C of the entire oil and fat is 1.5 to 13%, the method comprising the steps of obtaining an oil phase containing the oil and fat, obtaining an aqueous phase containing water, and mixing and emulsifying the oil phase and the aqueous phase, wherein the oil phase and / or the aqueous phase contains an emulsifier.
[0041] When the oil and fat composition for cooked rice is an emulsified composition containing water, the oil and fat composition for cooked rice as a whole only needs to contain an emulsifier. In the production method, when the aqueous phase contains an emulsifier, the oil phase may be composed of oil and fat only, or may be composed of a mixture containing oil and fat and a lipophilic emulsifier. Furthermore, whether the oil phase is composed of oil and fat only, or a mixture containing oil and fat and a lipophilic emulsifier, it may also contain other lipophilic ingredients. Furthermore, in the production method, when the oil phase contains an emulsifier, the aqueous phase may be composed of water only, or may be composed of a mixture containing water and a hydrophilic emulsifier. Furthermore, whether the aqueous phase is composed of water only, or a mixture containing water and a hydrophilic emulsifier, it may also contain other hydrophilic ingredients.
[0042] Even when the oil / fat composition for cooked rice is an emulsified composition containing water, in the step of obtaining the oil phase, it is sufficient to mix all of the ingredients constituting the oil phase, and it is preferable that the oil / fat is melted in advance. The temperature at which the oil / fat is melted and the temperature at which the oil / fat mixture is stirred may be within the above-mentioned ranges.
[0043] In the step of obtaining the aqueous phase, all of the raw materials constituting the aqueous phase are mixed together. The temperature of the water may be 50 to 80°C, and the temperature of the aqueous phase mixture during stirring may be maintained at 65 to 80°C. Maintaining the temperature of the aqueous phase mixture at 65 to 80°C for about 20 to 35 minutes is preferred because sterilization can be achieved.
[0044] In the step of mixing and emulsifying the oil phase and the aqueous phase, the mixing is preferably carried out at 65 to 75°C.
[0045] After the step of mixing and emulsifying the oil phase and the water phase, it is preferable to knead the mixture while cooling it to 5 to 20° C. The kneading can be carried out using a cooling kneader.
[0046] (Rice food) The present embodiment relates to a cooked rice food product in which the oil and fat composition for cooked rice is mixed in an amount of 0.5 to 10 parts by weight per 100 parts by weight of cooked rice.
[0047] The cooked rice foods include cooked rice itself, which is made by cooking rice such as non-glutinous rice or glutinous rice, and foods containing cooked rice. Foods containing cooked rice include cooked rice topped with or mixed with ingredients, cooked rice that has been seasoned and cooked, and cooked mixtures of rice and other foods. Specific examples include fried rice, pilaf, paella, seasoned rice, omelet rice, nasi goreng, biryani, jambalaya, oyakodon (chicken and egg rice bowl), gyudon (beef bowl), phat kapao rice, khao man gai (chicken stew), bibimbap, and sirpancho (simmered rice dish).
[0048] The amount of the oil and fat composition for cooked rice mixed in the cooked rice food product may be 0.5 to 10 parts by weight, preferably 0.5 to 5 parts by weight, and more preferably 0.5 to 3 parts by weight, per 100 parts by weight of cooked rice. If the amount is less than 0.5 parts by weight, the cooked cooked rice food may not have a sufficient flaky texture. If the amount is more than 10 parts by weight, the cooked cooked rice food may tend to feel oily when eaten.
[0049] The method of mixing the cooked rice food with the oil and fat composition for cooked rice is not particularly limited, but in order to more effectively achieve the effect of imparting a crispy texture to the cooked rice food of the present invention, it is preferable to mix the cooked rice food and the oil and fat composition for cooked rice when at least one of them is at 40°C or higher, and it is more preferable to mix both the cooked rice food and the oil and fat composition for cooked rice when they are at 40°C.
[0050] The oil and fat composition for cooked rice can be used as an oil and fat for cooking such as frying oil or rice cooking oil.
[0051] The frying oil can be used in the same way as oils commonly used as frying oils when frying.
[0052] The use as a rice cooking oil and fat includes both cases in which the oil and fat composition for cooked rice is added before cooking rice and cases in which the oil and fat composition for cooked rice is added after cooking rice.
[0053] Even when a cooked rice food is cooled and then reheated immediately after cooking, the rice food can maintain the same crispy texture as immediately after cooking. The cooling of the cooked rice food immediately after cooking may be to a temperature range generally referred to as freezing or refrigerating (chilled). Here, "frozen" may be, for example, below 0°C, such as -10°C or below, or -18°C or below, and "chilled" may be a low temperature that does not freeze, such as 0 to 15°C. Here, "reheating" refers to heating a frozen or refrigerated cooked rice food to a temperature suitable for eating, such as 50 to 100°C. Such reheating is not particularly limited as long as it is a method that raises the temperature of the cooked rice food, and can be carried out, for example, using a microwave oven, a toaster oven, or the like.
[0054] In addition to the oil and fat composition for cooked rice containing the oil and fat and the emulsifier, the cooked rice food product may contain, as necessary, the flavoring, coloring, antioxidant, pH adjuster, thickener stabilizer, sugar, sweetener, spice, seasoning, ingredients, etc., as long as the effects of the present invention are not impaired.
[0055] The seasoning may be any of those generally used in food to adjust the flavor, such as sugar, salt, soy sauce, miso, mirin, sake, Worcestershire sauce, oyster sauce, umami seasoning, bonito stock, kelp stock, meat extract, marine extract, vegetable extract, yeast extract, etc., and at least one selected from this group may be used.
[0056] The ingredients may be either plant-based or animal-based. For example, vegetables such as onion, chive, green onion, shiso leaf, lettuce, cabbage, Chinese cabbage, tomato, potato, carrot, green pepper, spinach, broccoli, corn, zucchini, eggplant, pumpkin, radish, asparagus, bamboo shoot, ginkgo, etc., mushrooms such as shiitake mushroom, shimeji mushroom, maitake mushroom, mushroom, etc., beans such as soybean, adzuki bean, kidney bean, pea, broad bean, lentil, chickpea, etc., meat such as beef, pork, chicken, lamb, etc., bacon, ham, sausage, roast pork, Examples of suitable raw materials include processed meat products such as corned beef, eggs such as chicken eggs, quail eggs, salmon roe, caviar, herring roe, cod roe, trout roe, flying fish roe, and dried mullet roe, seafood such as shrimp, cherry shrimp, whitebait, crab, squid, octopus, scallops, and salmon, processed fish products such as kamaboko, hanpen, imitation crab sticks, and chikuwa, seaweed such as wakame seaweed, kelp, nori seaweed, and hijiki seaweed, fermented foods such as natto and kimchi, and pickles such as umeboshi (pickled plum), takuan (pickled radish), and takana (green mustard greens). At least one selected from these groups can be used.
