Abstract: A calcium salt protective coating formed in situ by combining fatty acids with lime, also the associated method of forming the protective coating in situ. The fatty acids are preferably vegetable fatty acids such as from soapstock byproduct skimmings produced during the manufacture of vegetable oil.
