Potato tubers — proximate composition (Feedipedia)
Source: Feedipedia (INRAE/FAO open ingredient database), page "Potato (Solanum tuberosum) tubers | Feedipedia" (feedipedia.org/node/547). First-hand web text extracted (tags stripped) to pdf-raw/feedipedia/ingredient_potato_tubers.txt; composition values are verbatim from the page's proximate ("Main analysis") table. Units as published (% as fed / % DM / MJ/kg DM / g/kg DM). Avg/SD/Min/Max/Nb columns preserved.
