[Music] this is standard sea salt but after 30 days it'll become this high quality bamboo salt costs almost a hundred dollars for an eight and a half ounce jar making it the most expensive salt in the world so what is bamboo salt used for and why is it so expensive for hundreds of years koreans have used bamboo salt for cooking and as a form of traditional medicine it's made by placing sea salt inside of bamboo and roasting it at a high temperature the goal is to infuse the salt with minerals from the bamboo and to remove any impurities but the premium compared to other types of salt is steep nine times roasted bamboo salt sometimes referred to as purple bamboo salt can cost over 10 times the price of pink himalayan salt most of that cost comes from the labor intensive process the process starts by cutting three-year-old bamboo into uniform trunks leaving one side closed as a container for the salt sea salt from the west coast of korea is densely packed by hand into the bamboo workers load filled bamboo onto a cart and push it into a kiln traditionally only pine logs are used this process takes around 12 to 14 hours baking everything at over 800 degrees celsius burns away the bamboo leaving a column of salt but the process has only just begun [Music] foreign the ninth and final roast is the hottest at over one thousand degrees celsius it's fired in a special kiln and operated by an expert shintae jun has been making bamboo salt for over 20 years that experience is extremely important because any error at this stage could result in wasting a month of work at this temperature the salt and bamboo completely melt and drain into a mold after a few days of cooling a blackened rock-like structure remains this is nine times roasted bamboo salt workers carefully break this down by hand trying not to waste any material [Music] after a month of work it's ready to be packaged and soldered the final price varies depending on where you buy it and what form it's in but nine times roasted bamboo salt doesn't come cheap [Music] and [Music] [Music] the health benefits of food have always played an important role in korean culture for centuries bamboo salt baked two to three times has been used in traditional korean medicine but in the 20th century the nine times roasting process was developed manufacturers say this process is the lowest toxicity and highest mineral content today it's used for cooking toothpaste soap and various remedies for proponents of bamboo salt say that it can help with everything from digestion to oral health skin care and inflammation that it even has anti-cancer effects but proposed medical benefits have likely helped it maintain its high price but there hasn't been enough scientific study to fully back up all of these claims studies have shown that bamboo salt contains higher levels of iron potassium and calcium compared to regular sea salt and that it could improve your immune system but these beneficial minerals constitute only a small percentage the majority of bamboo salt is sodium chloride even with lower toxicity it's unclear how potent the health benefits are in 2016 the who wrote in a report that the composition of specialty salts poses no toxicological risks but does not offer any relevant nutritional benefits either the full benefits of bamboo salt compared to sea salt have yet to be extensively researched but despite that bamboozle continues to be popular in sangha a popular bamboo salt maker earned around 24 million dollars in sales in 2017 and the traditional labor intensive process isn't likely to change anytime soon
