However, these methods simply add general edible oils and fats when cooking rice, and during cooking, large oil droplets form on the water surface and do not spread evenly throughout the rice cooker. The absorption of edible oil remains extremely uneven; encapsulating edible oil helps improve the workability of adding oil; An oil-in-water emulsion of oil and fat is added to the rice during cooking to improve dispersibility, but advanced technology is required to improve emulsification to maintain the uniformity of the emulsion and to improve bacterial resistance to prevent spoilage. This method has unresolved problems such as the need for high-performance production equipment, and as in the present invention, the edible fats and oils added during rice cooking are uniformly dispersed and adsorbed to the cooked rice, and the method uses simple heating and
There is no known cooking oil that can be produced using stirring and dissolving equipment.

(Means for Solving the Problems) As a result of intensive studies, the present inventors noticed that the synergistic effect of lecithin and food surfactants other than lecithin increases the surface tension lowering ability for fats and oils. The present invention was completed by discovering that the dispersibility of edible oil and fat on the water surface of a rice cooking pot is improved by utilizing the method, and that the edible oil and fat forms a light emulsion with the rice cooking water when boiling, and is uniformly dispersed and adsorbed throughout the cooked rice.

If the amount of lecithin or food-grade surfactant other than lecithin used is less than the specified amount, the above-mentioned dispersibility will not be sufficiently obtained, and if it exceeds the specified amount, the transparency of the cooking oil will be impaired and the food-grade surfactant will precipitate. This causes the ingredients of the cooking oil to become uneven. Furthermore, if the amount used is too large, the flavor of the food surfactant becomes strong, which is not preferable.

The dispersibility on the water surface of the rice cooking part according to the present invention is 4 to 6 times that of corn salad oil alone, due to the synergistic effect of surface tension reduction between lecithin and the food-grade surfactant other than lecithin, and that of lecithin or other food-grade surfactants. It was improved by about 4 times compared to the one with only food-grade surfactant added.

(Effect of the invention) The rice cooking section manufactured according to the present invention has a synergistic effect between the lecithin added to the edible fat and other food surfactants, which lowers the surface tension of the oil. When this occurs, the oil does not form as oil droplets on one area of the water surface, but instead forms a thin oil film that spreads over a wide area. As the cooking water boils, the oil film forms an emulsion with the cooking water and is uniformly dispersed and adsorbed throughout the cooked rice. This maintains the uniformity of the edible oil and fat on the entire surface of the rice cooker, in the upper and lower layers, and improves the flavor of the cooked rice.
The texture, gloss and stickiness became uniform.

Since the added edible oil and fat is uniform within the cooked rice, the effect of adding edible oil and fat to the cooked rice is fully demonstrated, and it no longer sticks to rice cookers, strainers, packaging containers, wrapping paper, etc., and workability is improved. It was done.

Since the physical properties of the rice cooking part of the present invention are the same as those of general edible fats and oils, no special consideration is required during rice cooking operations. or,
Because the rice cooking part always maintains homogeneity, unlike emulsion types, there is no need to worry about separation or spoilage, and the viscosity is low, making it easy to handle and less likely to stick to containers.
