Embodiment 1

[0035] A rice processing method. First, the harvested fresh rice is treated at 75°C for 9 hours, then processed into polished rice, and transferred to a closed container. The nitrogen flow is blown into the nano-zinc oxide whisker until the internal pressure is 5MPa, and the pressure is maintained. Treat for 40 minutes, release the pressure instantly, then separate and remove the nano-zinc oxide whiskers to obtain pretreated polished rice, and finally add the pretreated polished rice to the fermentation broth for ultrasonic oscillation, pulse magnetic field treatment, filter, and air-dry in a drying room until the water content is 15%. , can be packaged; wherein, the preparation method of the fermented liquid is as follows: first inoculate Aureobasidium pullulans and Sclerotinia sclerotinum into a sterilized liquid medium, ferment, and centrifuge to take the supernatant to obtain the fermented liquid.

[0036] The specific process of processing into polished rice is:

Embodiment 2

[0054] A rice processing method, the fresh harvested rice is first processed at 85°C for 6 hours, then processed into polished rice, transferred to a closed container, nitrogen flow is blown into nano-zinc oxide whiskers, until the internal pressure is 8MPa, and the pressure is kept Treat for 30 minutes, release the pressure instantly, then separate and remove the nano-zinc oxide whiskers to obtain pretreated polished rice, and finally add the pretreated polished rice to the fermentation broth for ultrasonic vibration, pulse magnetic field treatment, filter, and air-dry in a drying room until the moisture content is 16%. , can be packaged; wherein, the preparation method of the fermented liquid is as follows: first inoculate Aureobasidium pullulans and Sclerotinia sclerotinum into a sterilized liquid medium, ferment, and centrifuge to take the supernatant to obtain the fermented liquid.

Embodiment 3

[0073] A rice processing method, the fresh harvested rice is first processed at 80°C for 8 hours, then processed into polished rice, transferred to a closed container, nitrogen flow is blown into nano-zinc oxide whiskers, until the internal pressure is 7MPa, and the pressure is maintained. Treat for 35 minutes, release the pressure instantly, then separate and remove the nano-zinc oxide whiskers to obtain pretreated polished rice, and finally add the pretreated polished rice to the fermentation broth for ultrasonic oscillation, pulse magnetic field treatment, filter, and air-dry in a drying room until the moisture content is 15.5%. , can be packaged; wherein, the preparation method of the fermented liquid is as follows: first inoculate Aureobasidium pullulans and Sclerotinia sclerotinum into a sterilized liquid medium, ferment, and centrifuge to take the supernatant to obtain the fermented liquid.

Abstract

The invention provides a processing method of rice. The method comprises the following steps that firstly, heat treatment of harvested fresh rice is directly carried out, then the rice is processed into polished rice, the polished rice is transferred into a closed container, nitrogen flow is blown into nano zinc oxide whiskers, treatment is carried out under a pressure condition, pressure is instantaneously released, then the nano zinc oxide whiskers are separated to remove to obtain pretreated polished rice, finally, the pretreated polished rice is added into fermentation liquor for ultrasonic oscillation, pulsed magnetic field treatment and filtering, the rice is air-dried in a drying chamber until the weight content of water is 15-16%, and packaging is carried out. A preparation methodof the fermentation liquor comprises the following steps that aureobasidium pullulans and sclerotium rolfsii are inoculated into a sterilized liquid culture medium, fermenting and centrifuging are carried out to take supernate, and the fermentation liquor is obtained. Rice products obtained through the processing method have good storage stability, insects, molds and the like cannot grow after therice products are stored for a long time, and the rice quality can also be well maintained.

Description

technical field [0001] The invention relates to the technical field of rice processing, in particular to a rice processing method. Background technique [0002] my country is a country with a large population and a large agricultural country, so food security is particularly important. Due to the loss of the shell and peel of rice, the hydrophilic colloid of rice grains rich in nutrients is extremely vulnerable to oxygen in the air, insects, and molds. In addition, rice contains varying degrees of bran layers and rice grains are exposed, directly in contact with the temperature and humidity of the external environment. , easy to absorb moisture, easy to explode, and easy to age, so rice is more difficult to keep fresh than paddy and brown rice. For a long time, due to the backwardness of fresh-keeping technology, the loss of my country's rice in the process of storage, transportation and marketing has reached more than 10-15%. The main component of rice is starch, which is...
