Argan oil is prepared by cold pressing argan kernels collected from fully ripe fruit. Argan oil market price is particularly elevated. Consequently, efficient methods to ascertain its authenticity and quality are looked for by industrials as well as individual consumers. Argan oil element profile has already been shown to be sufficiently singular to be used to certify its authenticity. Quantification of eleven elements (Ca, P, Mg, Mn, K, Cu, Fe, Cd, Cr, Zn, and Sn) indicated a 55 to 60% increase in global metal content in argan oil prepared from fully ripe fruit, compared to argan oil prepared from unripe fruit. Individual variations are herein reported and our study demonstrates that argan oil element profile allows to certify the degree of maturity of the argan fruit at its harvest time and hence to guarantee the respect of one essential parameter necessary to get an argan oil of high nutritional quality.

摩洛哥坚果油元素含量是用于其制备的水果质量的有力标志

摩洛哥坚果油是通过冷压从完全成熟的水果中收集的摩洛哥坚果仁制成的。摩洛哥坚果油市场价格特别高。因此，工业界和个人消费者都在寻找确定其真实性和质量的有效方法。摩洛哥坚果油元素剖面已被证明是足够单一的，可用于证明其真实性。11 种元素（Ca、P、Mg、Mn、K、Cu、Fe、Cd、Cr、Zn 和 Sn）的定量表明，与完全成熟的水果相比，由完全成熟的水果制备的摩洛哥坚果油中的全球金属含量增加了 55% 至 60%由未成熟的水果制成的摩洛哥坚果油。
