Problems solved by technology

[0003] Fresh-keeping rice has not been promoted rapidly since it was put on the market in my country. The main reason is that there are obvious shortcomings in the taste of existing fresh-keeping rice products in my country. From the processing method, fresh-keeping rice adopts aseptic processing technology. Inhibit the growth of harmful microorganisms, add a pH regulator to adjust the pH of the rice to about 5, and it will have an obvious sour taste when eaten, so some products are made in the form of rice bowls, and the sour taste of the rice is covered with a strong soup; secondly, In the production process, a combination of ordinary steaming and high-temperature sterilization is adopted. The cooking time of rice is too long, and it is in excessive contact with water or water vapor during the cooking process, which cannot maintain the taste and texture of fresh rice. When eating, there is a sense of slag, lack of elasticity and smooth taste, the taste and various parameters are far from traditional steamed rice, and the nutrition is single and the content of dietary fiber and vitamins is low

Embodiment 1

[0028] A. Rice washing: wash the rice quickly with cold water and hot water, drain and put it in a container, and add hot water; B, microwave heating: use microwave to heat the mixture obtained in step A; C, sealing: in step Add hot pumpkin soup to the mixture obtained in B, stir evenly and spread the rice so that the rice does not exceed the edge of the container, fill it with nitrogen, and seal it; D: Autoclave: Sterilize the sealed rice under high temperature and high pressure in a water bath.

[0029] In the step C, the rice is sealed with nitrogen gas by using a film sealing machine, and the temperature of the film sealing machine is 150°C.

[0030] In step D, the sealed box is sterilized in a water bath in a sterilizer, and the steps include water injection, temperature rise, heat preservation, hot water recovery, cooling water injection, cooling cycle, and drainage and exhaust.

[0031] The microwave power of the microwave heating described in step B is 3.2kw, and the t...

Embodiment 2

[0039] The difference with embodiment 1 is:

[0040] The microwave power of the microwave heating described in step B is 6.5kw, and the time is 120s.

[0041] In the step A, the weight ratio of the original weight of rice to water in the system after adding hot water is 1:1.

[0042] In the step C, the ratio of the original weight of rice in the system to the weight sum of water and pumpkin soup after adding hot pumpkin soup is 1:1.5.

[0043] The preparation method of the pumpkin soup described in step C is as follows: peel the pumpkin, remove the pulp, and dice the pumpkin, mix the diced pumpkin and water at a mass ratio of 1:5, boil for 2.0 hours, then filter, and discard the filter residue to obtain hot pumpkin soup.

[0044] In the step C, the rice is sealed with nitrogen gas by using a film sealing machine, and the temperature of the film sealing machine is 250°C.

[0045] In the step D, the upper limit of the sterilization pressure is 2.0 MPa, the sterilization temperat...

Embodiment 3

[0047] A. Rice washing: wash the rice quickly with cold water and hot water, drain and put it in a container, and add hot water; B, microwave heating: use microwave to heat the mixture obtained in step A; C, sealing: in step Add hot pumpkin soup to the mixture obtained in B, stir evenly and spread the rice so that the rice does not exceed the edge of the container, fill it with nitrogen, and seal it; D: Autoclave: Sterilize the sealed rice under high temperature and high pressure in a water bath.

[0048] In the step C, the rice is sealed with nitrogen gas by using a film sealing machine, and the temperature of the film sealing machine is 190°C.

[0049] In step D, the sealed box is sterilized in a water bath in a sterilizer, and the steps include water injection, temperature rise, heat preservation, hot water recovery, cooling water injection, cooling cycle, and drainage and exhaust.

[0050] The microwave power of the microwave heating described in step B is 4.5kw, and the t...

Abstract

The present invention discloses a production method of preservation pumpkin cooked rice and the preservation pumpkin cooked rice. Specifically, the processing method comprises the following steps: A, rice washing: hot water is added into washed rice; B, microwave heating: microwave is used to heat the obtained mixture in the step A; C: sealing: pre-cooked pumpkins are added into the mixture obtained in the step B, hot pumpkin soup juice is supplemented, nitrogen is filled, and the mixture is sealed; D: high pressure sterilizing: the sealed cooked rice is subjected to water bath high temperature and high pressure sterilization; and the original mass of the rice in the step A accounts for 40%-98% of the total mass of the original mass of the added pumpkins in the step C and the original mass of the rice. The produced preservation cooked rice by the method is not sticky in cooked rice grains, good in flavor, rich in dietary fibers and vitamins, long in shelf life and easy to eat and use.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a rice processing method. Background technique [0002] People in many countries in the world like to eat rice, but because the cooking time is long, and it is not easy to carry and place for a long time, it is difficult to adapt to the needs of the modern rhythm of life. For this reason, instant rice is gradually paid attention to by people. According to pertinent data, in all developed countries and regional supermarkets, the proportion of staple and non-staple food convenience foods is up to more than 20%, and instant rice is one of them. The sales volume of Japanese instant rice is only second to instant noodles. From the perspective of development trend, instant rice will develop in the direction of full nutrition, fortification, and excellent packaging. There is a wide range of potential demand in Asian and European and American markets. China is one of the main ...
