There are several ways to handle sulfur-smoked food to ensure it is safe to eat:
Edible alkali soaking and cleaning: You can add a little alkali to clean water for soaking and cleaning, which can degrade a lot of sulfur.
Fumigation removal: Smoke the food first and then put it in a pot to steam, which can remove the sulfur from the surface of the food.
Soak in warm water to remove sulfur.
Soaking in vinegar water: Soak the sulfur-smoked food in vinegar water for 20-30 minutes, then gently scrub it with your hands to remove the sulfur smell on the surface.
Microwave oven heating: For foods that need to be processed, such as Chinese herbal medicines, consider microwaving them to remove sulfur residues.
It is important to note that although these methods can remove sulfur residues from sulfur-smoked food, it is best to purchase strictly tested foods through regular channels to ensure that they are safe to eat. At the same time, according to the "National Food Safety Standard for the Use of Food Additives" GB2760-2014, sulfur is allowed to be used in smoking some foods, but the maximum amount used is measured by sulfur dioxide residues, so when processing sulfur-smoked food, the residue of sulfur should be strictly controlled to avoid health hazards. In addition, sulfur-smoked food may have an impact on the texture and taste of the food, so the state and smell of the food should be carefully checked before consumption to ensure that there is no sulfur smell or other off-flavors.
