I've worked in this industry for many years. Everything you see or read is all being controlled by the manufactures of the ingredients + the manufactures of the product to finally being label under controlled agencies by them.

I'm not being harsh , or stating that openfoodfacts is not good or the info you get is not real / valid. they basically have what they gave them.

The industry (food and cosmetic) is in the paleolithic era , everything is being send and share on .csv or with proprietaries API (exam Nilsen), data aggregators using GS1 which is horrible, being parsed by some kind of ML algos that companies are writing , trying to uniform product data, trying to correct typos , clarify if the formulas are harmful for humans or not base on years of multiple studies and proprietary logic, that change more often than not. It Is a mess

There is a lot of good intentions, a lot of good people that they really care and want to change the market to create better products (starting from creating better ingredients) but honestly is not going to happen any time soon. Is just simply too big of an industry with years of legacy.

The only light I see is to start from 0, new small brands that may manufacture cosmetics and food and they can control what is being engineer inside , and they can store data in modern DBs and using Modern API design to expose the data and allow corrections. Is the only solution I see.
