1 The Dangers of Eating Dried Bamboo Shoots with Sulfur Content
To prevent mold from forming on bamboo shoots, some people use sulfur dioxide (SO2) as a preservative. This involves burning sulfur, which transforms into SO2, killing microorganisms and inhibiting mold growth. However, excessive use of this method can lead to harmful health effects.
When the sulfur content exceeds 20 milligrams per kilogram of product, it can cause nerve damage, alter behavior, and impact the circulatory and cardiovascular systems. Additionally, it may lead to reduced vision, eye damage, impaired reproductive function, weakened immune system, endocrine disorders, and adverse effects on brain development.
Furthermore, high sulfur intake can also damage the lungs, eyes, and kidneys, and cause blood poisoning.

3 How to Remove Sulfur from Dried Bamboo Shoots
To eliminate SO2 from dried bamboo shoots, it is recommended to soak and rinse them thoroughly before cooking. Boil the shoots once and discard the water. This process helps to remove sulfur through evaporation or dissolution in water. For added safety, it is advisable to boil the bamboo shoots twice before using them in your recipes.
Here’s a step-by-step guide to properly boiling dried bamboo shoots:
– Clean the dried bamboo shoots thoroughly to remove any dirt or debris. Soak them in water for at least 5-6 hours, or preferably overnight, to ensure they become sufficiently tender.
– After soaking, drain the water and place the bamboo shoots in a pot. Cover them with water and bring to a boil. Let them simmer for about an hour over medium heat. Continue cooking until the water has evaporated, then add fresh water and boil for another hour to further soften the shoots. Make sure the shoots remain submerged in water throughout the process.
– When soaking the bamboo shoots, you can use rice washing water to help speed up the softening process and ensure even cooking.
– Once the bamboo shoots are tender, remove them from the heat and drain the water. Allow them to cool, then shred the shoots into thin strips and rinse again with clean water. At this point, the bamboo shoots are ready for use in your desired recipes.
– If you have any leftover boiled bamboo shoots, store them in a sealed bag in the refrigerator. They will stay fresh for about a week in the chiller and up to a month in the freezer.
Dried bamboo shoots are commonly used in various dishes during the Tet holiday. Therefore, knowing how to identify and remove sulfur from this ingredient is crucial. To ensure the health and safety of your loved ones, keep these tips in mind when preparing dishes with dried bamboo shoots.
