In recent months I have been paying particular attention to food costs. As part of that I have looked at the price of different fruit. It is easy to calculate the price per Kg of unprepared fruit, and I am surprised how cheap for example pineapple is compared to locally produced fruit. However I suspect there could be more wastage in pineapples.
I could work this out for myself, ie. weigh the product before and after preparation. However I thought that this must be a core variable that goes into food production process control calculations, so someone must have worked out wastage rates for all sorts of products under all sorts of conditions. Are these publically available? I think they would be very useful to a lot of people, particularly in the present economic circumstances.
