Description

Method for preparing instant cooked rice
Technical Field
The invention relates to the technical field of instant food processing, in particular to a method for preparing instant cooked rice.
Background
The rice is convenient to prepare, and the requirement of people for quickly solving the problem of eating at present is met. The conventional instant prepared rice is prepared by steaming rice, adding livestock and poultry meat and eggs, adding seasonings, frying, and cooling or freezing. The method is a processing idea of traditional fried rice and a manufacturing idea of household fried rice.
The steps of the existing method are as follows: soaking dried rice, steaming with steam, adding flavoring agent, vegetable, meat, and fowl egg product, stirring, parching, cooling, freezing, and packaging. The whole production environment temperature is normal temperature, and the stirring and frying processes are high temperature after the rice is steamed in the processing process.
The existing preparation method has mature process and convenient eating, but has a plurality of defects: during the cooking process of the rice, the starch is completely gelatinized, but in the cooling and storing process, along with the change of temperature and time, retrogradation phenomena with different degrees occur, namely, the molecular structure of the starch is restored again and is irreversible, so that the rice has a raw and hard taste and loses Q elasticity when being eaten, and the rice is not as soft, delicious, chewy and easy to digest like fresh rice.
Disclosure of Invention
The invention aims to provide a method for making fresh instant modulation rice, which aims to solve the technical problems that the conventional instant modulation rice has a stiff mouthfeel, is not fresh and elastic enough, is not easy to digest and cannot be sufficiently absorbed due to the retrogradation phenomenon after the rice is cured.
The invention conception of the invention is as follows: the completely gelatinized starch has retrogradation phenomenon when the temperature is reduced, and in order to realize that the fresh Q elasticity can be embodied when the conveniently prepared rice is eaten, a method is adopted to ensure that the starch is completely gelatinized only when the rice is eaten and heated. The invention aims to ensure that a finished product is gelatinized to a certain degree instead of completely by accurately controlling the water content and the temperature in the processing process, and the gelatinization of the rice starch is completely finished only by fully heating and curing after being frozen or refrigerated for a certain time when being eaten, so that the full freshness and Q elasticity are obtained.
The retrogradation of starch is avoided by adding food additives which inhibit retrogradation of starch in the prior art, which means that the skilled person does not think about retrogradation by means of incomplete gelatinization, and if thought, does not know how to achieve the retrogradation, or has poor effect, and the use of food additives is normal because there are many factors which influence the gelatinization of starch and how to control variables is unknown.
Through a great deal of research, the inventor finds that in the instant cooked rice, the water content (mass fraction) in the cooked rice is accurately controlled to be 63-67%, and the semi-finished cooked rice is controlled to be cooked rice with the central temperature of 70-75 ℃, so that the prepared incompletely gelatinized cooked rice has the best eating effect when being heated after being refrigerated.
Even if the water content in the rice is controlled to be 63-67%, the skilled person does not know how to realize the control, and the inventor finds that the prepared semi-finished rice is loosened, the water content in the rice can be accurately controlled to reach the required range by adjusting the cooling time and the amount of ice water, namely, the semi-finished rice is rapidly cooled to 10 ℃ within 1 minute by spraying the ice water with the weight being 10 times that of the semi-finished rice, so as to lock the water in the rice.
The invention has two functions of controlling the moisture content: 1. the retrogradation speed of the starch with the water content of more than 10 percent and less than 60 percent is higher, and the water content of more than 63 percent can slow down the retrogradation speed of the gelatinized starch in the rice in the storage process, thereby being beneficial to improving the mouthfeel when being eaten. 2. The rice is cooked, and simultaneously, the starch in the rice is not completely gelatinized by matching with the hot processing temperature and time of the rice; when the rice is eaten, the rice is completely gelatinized by microwave heating, and the whole processing process of the rice is finished. Thus, the taste of the food is completely fresh when the food is eaten. Below this moisture level will affect the rate of rice ripening and starch gelatinization and retrogradation.
Therefore, the invention adopts the following technical scheme:
the method for preparing the fresh instant mixed rice comprises the following steps:
(1) Taking a required amount of rice, and preparing semi-finished rice with incompletely gelatinized starch, wherein the central temperature is 70-75 ℃;
(2) And loosening the prepared semi-finished rice, quickly cooling the semi-finished rice to 5-15 ℃ by using ice water, and adjusting the cooling time and the ice water amount to ensure that the water content in the semi-finished rice is 63-67%.
(3) Adding other food materials and flavoring agents, and stirring.
Preferably, in the step (1), the semi-finished cooked rice which is not completely gelatinized is cooked rice, and the central temperature is 70 to 75 ℃.
Preferably, in the step (1), the method of preparing the incompletely gelatinized half-cooked rice comprises: soaking the rice for 30 to 50min, taking out the rice, adding water accounting for 68 to 72 percent of the weight of the soaked rice, and heating the rice for 3 to 5min by microwave.
Preferably, in the step (1), the method for preparing the incompletely gelatinized half-cooked rice comprises: soaking the rice for 30 to 50min, taking out the rice, steaming for 5 to 10min, and spraying water in the steaming process, wherein the water spraying amount is 68 to 72 percent of the weight of the soaked rice.
Preferably, in the step (2), the semi-finished cooked rice is rapidly cooled to 8-12 ℃ by using ice water, the weight of the ice water is 8-12 times of that of the semi-finished cooked rice, and the cooling time is within 1 min.
Preferably, in the step (3), the edible oil is added for stirring, and then the other food materials and the seasonings are added for stirring.
Preferably, in step (3), the other food materials are respectively fried or freshly cut and sterilized, and cooled to 0~4 ℃.
Preferably, in the step (3), the prepared cooked rice is subpackaged, sealed and refrigerated at 0~4 ℃ or refrigerated at-20 to-16 ℃.
Preferably, the refrigerated prepared rice is taken out within six days and is cooked by microwave for eating; taking out the product stored at the temperature of between 20 ℃ below zero and 16 ℃ within three months, unfreezing the product, and curing the product by microwaves for eating.
Compared with the prior art, the invention has the beneficial technical effects that:
1. the prepared convenient concocted rice can be eaten after being cooked by microwave, and has fresh eating experience, soft, glutinous and elastic mouthfeel. The method can keep the freshness and Q elasticity of the rice to the maximum extent while eating the rice conveniently and quickly, ensures the absorption of nutrient components, and is far superior to the prior traditional method.
2. The product prepared by the method does not contain any food additive for inhibiting starch retrogradation, and the problem of poor taste of the conveniently prepared rice caused by starch retrogradation is solved only by adjusting the process parameters.
3. The method of the invention can save heat by 30% because of adopting the incomplete gelatinization process in the processing process.
4. Compared with the traditional process, the method of the invention reduces the heating and frying working section and simplifies a working procedure.
