i did not find anything using google and the faq, i accidentally minted a zerocoin, does this apart from the transaction fee result in a loss of xzc when converting back after 7 confirmations?
That's the way to obfuscate the originating UTXO!
You sent your coin to the accumulator, made a Zerocoin and once you convert it back to XZC you have a brand new looking, shiny XZC (minus tx fee).
At least that's how I understood the white paper.
