Over the past one year, rice drinking straws have gradually become an alternative to plastic straws to reduce the amount of waste into the environment. Rice drinking straws are made from 100% natural ingredients that are totally safe for users’ health and the environment. So, how is the process of making rice drinking straws different from plastic straws? Let’s find out: how to make rice drinking straws with Xanh Vietnam.

Xanh Vietnam Rice Straws are made from whole grain rice that we use daily in our family meals combined with some natural color ingredients such as beetroot, activated charcoal, tapioca,… which are adjusted appropriately to create the color and durability of the straws.

The stages of making Rice Straws


Whole grain rice is pulverized and then filtered through a sieve. After that, the fine rice powder will be mixed with food colors derived from natural vegetables, tubers, and fruits such as black from activated charcoal, purple from beets, green from tea leaves, etc. This first phase is very vital because it affects the color of the outputs.

Once mixed, the rice flour will be steamed by an autoclave. Rice flour, after being steamed, will be transferred to a pelletizing machine to create small granules. This thermal addition phase helps the dough have toughness and elasticity, thus creating the durable rice straws in the drink.

After the thermal addition stage, the granules will be transferred to the extruder. The dough will be pressed into long tubes and then transported on a conveyor belt through a temporary cooling system with evaporator fans. The forming stage determines the diameter of each rice straw through the extruder heads. For instance: 6mm diameter rice straws, 8mm diameter rice straws, 12mm diameter rice straws, and so on.

At the end of the temporary cooling system, the cutting head determines the length of the tubes through the sensor and cuts the tubes to the calibrated length. This stage helps create the length of each type of rice straws such as 15cm, 20cm, 22cm, etc.

After being cut, the straws are not shaped yet, they will be carried to the dehydrating system. The straws are dried in roughly 60 minutes. The dehydrating system is programmed to heat in stages to ensure the greatest condition of straws after drying. This phase makes the straws dry and have a vertical shape.


After finishing the desiccating stage, the straws will be packed into standard packaging. The final straws have an expiry date under normal environmental conditions approximately 18 months on average. In room temperature and icy water, rice drinking straws can be kept in shape for up to 180 minutes. The rice straws will decompose immediately in the environment after use.
