Dried bamboo shoots are one of the common ingredients in households. Dishes like bone soup with dried bamboo shoots or stir-fried vermicelli with dried bamboo shoots are loved by many people. Especially in many regions, dried bamboo shoots are a traditional dish that cannot be missed on every Tet holiday.
However, many housewives are concerned that during the drying process, dried bamboo shoots may be treated with sulfur to prevent mold and create a beautiful yellow color. According to the recommendations of the World Health Organization, the sulfur content should not exceed 20mg/kg of the product. Dried bamboo shoots treated with sulfur are often bright or too dark in color, with a noticeable black odor. Therefore, when buying dried bamboo shoots, you should avoid choosing types of shoots with visible mold spots and pay attention to the color and aroma of the product.
How to process dried bamboo shoots to remove toxins
To remove natural toxins such as cyanhydric acid, you need to soak and boil the bamboo shoots thoroughly before processing. First, you need to clean the bamboo shoots and soak them in warm water or rice washing water for about 5-6 hours to make the shoots soften. If possible, you should soak the bamboo shoots overnight or soak them for 2-3 days and regularly change the water to remove toxins and bitter taste in the bamboo shoots.
After the bamboo shoots have softened, you need to rinse them several times with clean water and boil them in a pot filled with water. You can boil the bamboo shoots about 2-3 times, each time for about 30 minutes. After each boiling, you need to pour out the boiling water, rinse the bamboo shoots again, and pour in new boiling water. While boiling, you should slightly open the pot lid so that the toxins can escape.
When the bamboo shoots have softened and the boiling water becomes clear, you need to take out the shoots, rinse them with clean water, and wait for the shoots to cool and drain. Then, you can trim the older parts of the shoots, cut small pieces, or slice them according to the dish you want to cook.
If you want to preserve the boiled dried bamboo shoots, you can let them drain completely and put them in a tightly sealed container in the refrigerator. However, you should use up the boiled bamboo shoots within a week. If you want to extend the preservation time, you can put the shoots in the freezer, but you should not keep them for too long and should consume them within a month.
