METHOD FOR MANUFACTURING RETORT RICE, AND RETORT RICE

摘要

A method for manufacturing retort-pouch rice is described. The method makes it possible to implement a production process using an assembly line and increases production efficiency by reducing the amount of time taken by a preprocess prior to a retort sterilization process. The method is characterized in that: uncooked rice is treated by pressurized heated steam, forming a thin gelatinized layer in the surface layer of each rice grain and rendering the center of each grain porous; without being cooled, the rice grains are immediately sealed inside a container together with a prescribed amount of rice-cooking liquid; the rice grains are immersed in and made to absorb the rice-cooking liquid; the water-absorption state of the rice grains and the amount of rice-cooking liquid in the container are adjusted; and retort sterilization is performed.

主权项

1. A method for manufacturing retort rice, comprising the steps of:
forming a thin gelatinized layer on the surface layer of individual rice grains and making the center of each of the grains porous by treating uncooked rice with pressurized heated steam; immediately packing and sealing said rice grains inside a container together with a predetermined amount of a rice-cooking liquid without passing the grains through a cooling step; adjusting the state of absorption of said rice grains and the amount of rice-cooking liquid in the container by immersing said rice grains in the rice-cooking liquid and allowing the grains to absorb the liquid; and performing retort sterilization.
