Lime juice is a staple in my recipe. Have substituted with lemon juice when I'm surprised to not have lime available. It helps with the browning but not as much with the flavor
The link in my comment suggests that citrus juices actually _speed up_ browning, and I've seen other sources that corroborate this. Do it for flavor, certainly, but I wouldn't do it for preservation reasons!
