Guest Posted December 15, 2005 Share Posted December 15, 2005 Cos it just is Sorry, I don't have a clue, but as noone had posted a reply I did not want you to feel left out. All I can think of is that if it is pure fat without additives it would naturally last longer. Other things will oil mixed in with them do not last because of the chemical reactions probably. But to be honest I don't have a proper technical answer. Years ago, when you were a twinkle in your parents eye, things did not have sell by dates and use by dates and kept for years. Fat kept for months in the larder in the winter. Good insn't it? Means you can have a stock of it and not have to worry! Quote Link to comment Share on other sites More sharing options...
Mrs Blue Sky Posted December 15, 2005 Share Posted December 15, 2005 I think it's oxidisation that makes food go rank, ie exposure to air, also all the bacteria in the air plays its part too.. So if it is wrapped in the fridge it will be ok for ages. Also lard is a purified product, with all the bits that might go off, blood etc, taken away. So you can believe the sell by date I think - anyway if it goes rank you won't be in any doubt! It will ming big time!
