Table 6 The purpose of each step of cooking

Wash rise

Remove impurities and odors from rice grains, reduce potential arsenic or toxic metal contaminants

Liu et al. (2018) and Menon et al. (2021)

Add water

Provides water for starch gelatinization

Flooding

Make rice grain water absorption uniform, conducive to heating gelatinization

Heating

Provides the energy needed for starch gelatinization

Heat preservation

Use the remaining temperature in the pot to balance the water between rice grains, and make the starch gelatinize evenly
