The authors wrote that they gave 240 g fresh blueberries containing 253 mg anthocyanins. That would be 105mg anthocyanins per 100g (provided that the authors didn't actually mean 253mg/100g). According to this table, that's too low for the European Blueberry: https://www.intechopen.com/books/superfood-and-functional-food-the-development-of-superfoods-and-their-roles-as-medicine/anthocyanins-in-berries-and-their-potential-use-in-human-health https://www.intechopen.com/books/superfood-and-functional-fo... (What I am doing with my life? I don't even know what an anthocyanin is)

anthocyanins are a broad family of natural food colorings, they're what gives the berries their color. As for bio effects you can draw a nice graph of anthocyanin yield vs certain mold infections and some molds clearly can't grow in anthocyanins. The "industry" doesn't have a unified voice so on one hand the "lets market a concentrated extract as a super-bioreactive kinda-like an antibiotic but for mold prevention" is not coordinating with "lets enter the lucrative supplement marketplace which much like patent medicines a century ago promises everything to everyone". And a third group wants to sell the concentrated extract as a totally safe natural organic food coloring. Needless to say the regulators are freaked out that the same substance is being marketed as both a completely non bio active colorant, a patent medicine supplement of vague goodness, AND as a food color. So there is much legal freakout and in EU you can use blueberry juice as a food colorant or flavoring but not concentrated anthocyanins refined from blueberries as a food coloring, and/or its allowed in the USA I just can't remember.
