Hello All,
We are currently Oil Roasting mainly Peanuts for our facility. Sometimes in emergency situations we roast Tree Nuts such as Cashews, Hazelnuts, etc. Would anyone know if there is a cross contamination issue in regards to the Peanut and Tree Nut protein that may be left in the oil? I sometimes fear that when we roast Peanuts and then roast Tree nuts or vise versa that there will be some protein residue left in the oil. What are some people's thoughts as to this? And is there a proven process for this? We only have 1 Oil Roaster which is strictly for Peanuts.
