Where these numbers come from

Codex Alimentarius Commission (FAO/WHO)CXS 210-1999 Standard for Named Vegetable Oils, print of the 2019 revision (adopted 1999; revised 2001, 2003, 2009, 2017, 2019; amended 2005, 2011, 2013, 2015, 2019) · document dated 2019 · read 2026-09-20

Verbatim mirror of the FAO file CXS_210e.pdf; the official FAO link (https://www.fao.org/fao-who-codexalimentarius/sh-proxy/en/?lnk=1&url=https%3A%2F%2Fworkspace.fao.org%2Fsites%2Fcodex%2FStandards%2FCXS%2B210-1999%2FCXS_210e.pdf) was Cloudflare-gated at retrieval. Table 1 (Section 3.1) = mandatory GLC fatty-acid ranges, % of total fatty acids, ND = not detectable (<=0.05%). Table 2 (Appendix 'Other quality and composition factors') gives saponification value, iodine value (Wijs) and unsaponifiable matter of CRUDE oils; the Appendix is explicitly ADVISORY (a product not meeting it may still conform). This print predates the 2021-2025 amendments; the 2024 additions (avocado, camellia seed, sacha inchi, high-oleic soya bean) are not included.

Fatty acids from CXS 210 Table 1 (mandatory GLC ranges, % of total fatty acids; 'ND' = not detectable, <=0.05%, entries that are ND-only are omitted; C17:0, C17:1, C20:2, C22:2 and C24:1 columns omitted because they are outside this schema's key list). sapKohMgPerG, iodineValue and unsaponifiablePercent from Appendix Table 2 (crude oils; ADVISORY, not mandatory; unsaponifiable converted from g/kg). No 'typical' values are printed in the standard, so none are given. Erucic acid printed '> 2.0-60.0' (i.e. above the 2 % low-erucic limit, up to 60 %). C24:1 ND-3.0, C22:2 ND-2.0, C20:2 ND-1.0 omitted (outside key list).
