Buttermilk based or Yogurt-based marinades, rather than juice-based marinades. Plain yogurt, not greek yogurt (greek yogurt is more acidic). You will note that the faster marinade recipes call for greek yogurt specifically because it is more acidic - but because you are doing a longer marinade in the chill chest, you want to use a lower acidity.
Buttermilk pH 4.4-4.8
Yogurt pH 4.4-4.8
Greek Yogurt pH 4.0-4.6
Mayonnaise pH 3.6-4.0
Apple Juice pH 3.8+/-
Orange Juice pH 3.3-4.2
Pineapple pH 3.5 +/-
Lemon Juice pH 2.0-2.6
Lime Juice pH 2.0-2.4
The longer its in the marinade, the higher the pH you want (and then refridgeration is VERY important, because the lower acidiy does not retard the growth of pathogens as effectively.) bcause long rests at low pH is not good eats...
