I have been studying a bit on the formations of HMF in syrup,(also applies to honey) and find the heat and contact with steel accelerates the formation. What I am wondering does anyone know if this applies to Stainless steel or regular carbon steel? What I am wondering is if a stainless storage tank is as good as plastic for storage. All references I find only mention"metal" with my assumption being the acidic nature of syrup is causing some deteroation. I have not seen a problem in coated barrels either, but have not had HMF testing done on that syrup.
