Dear Mari, I believe that you have already looked in local/other food composition sources, which may contain information on recipe calculation. Did you make a Google Scholar search? – e.g. like nutrient retention “pressure cooking” ? – see https://scholar.google.dk/scholar?hl=en <https://scholar.google.dk/scholar?hl=en&as_sdt=0%2C5&q=nutrient+retention+%22pressure+cooking%22&btnG=&oq=nut> &as_sdt=0%2C5&q=nutrient+retention+%22pressure+cooking%22&btnG=&oq=nut You will get many good answers to your question with direct access to scientific articles (pdf), like https://core.ac.uk/download/pdf/35350331.pdf https://www.jstage.jst.go.jp/article/jnsv1973/36/4-SupplementI/36_4-SupplementI_S7/_pdf https://scholar.google.dk/scholar?output=instlink <https://scholar.google.dk/scholar?output=instlink&q=info:ysIpyRCy5AYJ:scholar.google.com/&hl=en&as_sdt=0,5&scillfp=2148603977735405212&oi=lle> &q=info:ysIpyRCy5AYJ:scholar.google.com/&hl=en&as_sdt=0,5&scillfp=2148603977735405212&oi=lle etc. Take a look at the articles and deduct the retention factors for the foods you have. To expand your search, you may also want to make a search on nutrient loss “pressure cooking” (https://scholar.google.dk/scholar?hl=en <https://scholar.google.dk/scholar?hl=en&as_sdt=0%2C5&q=nutrient+loss+%22pressure+cooking%22&btnG> &as_sdt=0%2C5&q=nutrient+loss+%22pressure+cooking%22&btnG=) – although you may get some of the same hits, there may be some sdditional specific to “loss”.

We are building a FCT for a study in Punjab, India, where pressure cooking of beans, legumes, potatoes and green leafy vegetables is common. We have not been able to identify nutrient retention factors for pressure cooking of these foods. I hope we can get some help here!
