Is queso blanco low histamine-compatible?

What to know about queso blanco

Queso blanco is the fresh white cheese of Latin American cooking, and it is made in a way that flips the usual cheese trigger profile on its head. Instead of rennet, the milk is curdled with acid, traditionally lime juice or vinegar, and the curd is pressed and eaten within days rather than ripened. Because nothing ages, almost no biogenic amines form, so it is graded low for histamine and low for tyramine, which is exactly where cheddar, parmesan and the blues are at their worst. The price of that freshness is the milk sugar. The curd is drained but not fermented, so the lactose stays in the cheese, and queso blanco is graded high for lactose along with maximum dairy protein. It is also the reason the cheese does not melt: an acid set casein network holds its shape when heated instead of flowing, which is why it softens and browns in a pan rather than stringing. Being acid set also means no animal rennet, which is why it grades as vegetarian friendly where many traditional cheeses do not.
