Hauv xyoo 1999, US Food and Drug Administration (FDA) tau pom zoo tias cov khoom noj ntxiv phytosterol thiab phytosterol ester tuaj yeem siv cov ntawv "hmoov zoo".

Xyoo 2010, cog phytosterols thiab phytosterol esters raug tso cai ntxiv rau cov zaub mov ua cov khoom noj tshiab (Food Safety Comprehensive Coordination and Health Supervision Bureau of the Ministry of Health of People's Republic of China, 2010 Third New Resources Food Bulletin).

Soy Steroltau raug pov thawj rau cov zaub mov nram qab no: zaub roj, zaub butter, margarine, khoom noj siv mis, zaub protein haus, condiments, zaub xam lav hnav khaub ncaws, mayonnaise, kua txiv hmab txiv ntoo, macaroni, noodles thiab neeg tsis noj nqaij cereals.
