Embodiment 1

[0019] This embodiment includes the following steps:

[0020] (1) Washing of raw rice: wash 10kg of rice with clean water to clean the powdery impurities adhering to its surface;

[0021] (2) First soaking: Soak the rice washed in step (1) in an aqueous solution containing 0.5wt% β-cyclodextrin and 0.25wt% monoglyceride at a temperature of 30°C. The soaking time is 55 minutes, so that the rice absorbs water and moistens;

[0022] (3) The first cooking: Drain the rice soaked in step (2) and steam for 10 minutes;

[0023] (4) Soaking for the second time: put the cooked rice obtained in step (3) into an aqueous solution containing 0.5wt% β-cyclodextrin and 0.25wt% monoglyceride for the second soaking, and the soaking solution also contains Add alkaline protease and β-amylase according to the ratio of 4000U alkaline protease and 1600U β-amylase to 100 grams of raw rice, the soaking temperature is 45°C, and the soaking time is 30 minutes;

[0024] (5) Second steaming: Drain the ...

Embodiment 2

[0030] This embodiment includes the following steps:

[0031] (1) Washing of raw rice: wash 10kg of rice with clean water to clean the powdery impurities adhering to its surface;

Abstract

The invention discloses a production method for convenient rice with a favorable retrogradation resisting performance, which comprises the steps of raw material rice washing, primary soaking, primary cooking, secondary soaking, secondary cooking, dispersing, drying and packaging, wherein a primary soaking solution is a water solution containing 0.2-0.8 percent by weight of beta-cyclodextrine and 0.1-0.4 percent by weight of monoglyceride; and a secondary soaking solution is a water solution containing 0.2-0.8 percent by weight of beta-cyclodextrine, 0.1-0.4 percent by weight of monoglyceride,1000-8000U / 100g of alkali protease of raw material rice and 300-3000U / 100g of beta- cyclodextrine of the raw material rice. According to the production method disclosed by the invention, the process is simple, the favorable retrogradation resisting performance of the dehydrated convenient rice can be improved, the mouthfeeling of the rice is improved and the rehydration time of the convenient rice is shortened; and the production method is more convenient to use.

Description

technical field [0001] The invention relates to a production method of instant rice, in particular to a production method of instant rice with good anti-retrogradation performance. Background technique [0002] In recent years, along with the improvement of people's living standards and the change of ideas, instant rice has been increasingly favored by people. However, the dehydrated instant rice products on the market generally have problems such as poor rehydration, stiff mouthfeel and poor flavor, which have seriously affected the popularization and promotion of instant rice. [0003] CN101731520A disclosed a process for making instant rice on June 16, 2010. The product is mainly prepared through elutriation, soaking for the first time, steaming for the first time, soaking for the second time, steaming for the second time, discrete and drying. wherein the soaking solution contains 0.2%-0.6% citric acid, 0.1%-0.3% beta cyclodextrin and 0.1%-0.3% sucrose fatty acid ester. ...
