Best way to structure array of data where each item can be separated into different parts?

I'm storing a list of recipe ingredients like this in Firestore:

Right now each array item is a String. It's occurred to me that if I eventually want to complete actions on the data, such as sum quantities of identical ingredients or convert units, I should separate each array item into its parts:

1. Quantity (Int)
2. Unit (String)
3. Food item (String)

How can data that can be broken down in that way be structured in a database (using Firestore in my case)? Would I need an array for each part?
