- Comparative Example 1-2 (Atmospheric steam cooking) 3.7 1.9 2.9
- Example 1 (superheated steam cooking) 4.3 2.6 3.3
- the rice of Comparative Example 1-1 prepared by the conventional boiling method had the lowest hardness and had a soft texture, but the surface of the rice was found to be roughly broken. It is expected that the broken grains of Comparative Example 1-1 were evaluated as showing a rather soft texture because long grains having hard characteristics were used.
- the instant rice of Comparative Example 1-2 prepared using normal pressure steam had a relatively smooth surface and an intact appearance compared to Comparative Example 1-1, but had high hardness and large grain variation, and texture and overall taste in sensory evaluation. It received the lowest rating and was of poor quality.

- the yields of the semi-finished products after superheated steam cooking in Example 2-1 and Example 2-2 all showed values within a suitable range.
- the high yield after cooking is the result of the rice grains being excessively swollen in water, which is related to the bursting of the rice grains.
- the yield is too low, moisture absorption is not performed at all, and the amount of water to be added after filling the container with rice grains increases, so that rice grains may become sticky during the retort heating process. Therefore, for the quality of the final product, an appropriate level of yield must be obtained from the semi-finished product.
- Example 2-1 cooked with superheated steam at 105 ° C, it showed hardness and L value almost close to that of uncooked rice, and the surface surface It was observed that it was only slightly swollen with water.
- Example 2-2 cooked with superheated steam at 125 ° C., although the hardness was high, a water retention film began to form on the surface to form stickiness, and it was confirmed that it was in the state of steamed rice.
- the instant rice of Example 2-1 cooked with superheated steam at a temperature of 105 ° C showed relatively high hardness and elasticity even after retort heating.
- the instant rice of Example 2-2 cooked with superheated steam at a temperature of 125 ° C had already undergone gelatinization to a large extent even before being put into the retort, and the hardness of the finished product was lower than that of Example 2-1, showing soft characteristics. It showed a good sense of organization. This is expected to be due to the rapid gelatinization caused by high energy in the process of cooking with superheated steam, minimizing the elution of starch.
- gelatinization of starch starts at 60°C - 80°C, and the higher the temperature and pressure, the easier it is.
- gelatinization is better than at 105°C, which is judged to be the result. do. That is, in the case of superheated steam temperature, the effect was not excellent in terms of physical properties at 105 ° C - 110 ° C, which can be said to be relatively low, but when cooked with relatively high temperature superheated steam of 110 ° C or higher, the effect was excellent with a soft texture did
- the superheated steam rice cooker used in this experimental example had three water nozzles, and cooking was performed by varying the amount of water sprayed from each nozzle.

In addition, instant rice was prepared without adding an emulsifier separately.
- Example 6-2 instant rice was prepared by spraying the emulsion before cooking with superheated steam. Specifically, in the case of Example 6-2, it was prepared in the same way as in Example 6-1, but before superheated steam cooking, 10 g of sunflower emulsion (6.6%, multi-in material) was sprayed on 300 g of long-grain jasmine, mixed well, Cooked with superheated steam.
- Example 6-3 instant rice was prepared by spraying the emulsion after overheated steam cooking. Specifically, Example 6-3 was prepared in the same manner as Example 6-1, but after superheated steam cooking, 30 g of sunflower emulsion (6.6%, multi-in material) was sprayed onto the cooked rice and mixed.
- Example 6-1 the yield after cooking without adding an emulsifier
- Example 6-2 the yield after adding an emulsifier and cooking
- Example 6-3 the yield after adding an emulsifier after cooking were measured respectively.
- the degree of grain separation (%) is calculated as a percentage (%) of the ratio of rice separated into 3 or less out of 50 g of cooked rice.
- Example 6-3 sprayed with emulsifier after cooking showed 84.06%
- Example 6-2 sprayed with emulsifier before cooking showed 73.08%
- Example without spraying emulsifier 6-1 was measured at 55.84%, confirming that it was easier to separate grains when instant rice was prepared by spraying an emulsifier after cooking.
- water is sprayed through a water nozzle to discharge cooked rice with a moisture content of about 40%.
- the grain separation effect is less than the grain separation effect.
- the grain separation effect may appear differently depending on the time of adding the emulsifier, and may be used by selecting the time of adding the emulsifier according to the type of rice used.
