Dear All,

I am working on dietary data from Tanzania, and have a question regarding nutrient retention factors. 

I have been applying nutrient retention factors from the USDA (release 6) based on cooking method to the food ingredients in my recipes, and then summing nutrient totals for the recipe. I have run into a problem with several dried fish recipes made frequently in Tanzania. Many of these recipes first fry the fish with some vegetables, and then boil the mixture. I am not sure how to account for this when applying retention factors. There are no factors that I can find for a stir-fry/boil cooking method. Also, the USDA's retention factors are based off of cooking raw fish, so am unsure if these could even be used for a dried fish. I was wondering if anybody had any wisdom about what to do when calculating nutrient values for these kinds of recipes. Thank you for your help.

Regards,
