The culinary difference between these two preparations rests on moisture management and chemical binding. Mayonnaise functions as a stable oil-in-water emulsion. When folded into poached shredded chicken, the fat coats the lean muscle fibers, preventing them from drying out even after 48 hours in the refrigerator. The starch from boiled potatoes also absorbs excess moisture, keeping the bowl thick rather than runny.
Lime-based vinaigrettes interact with vegetables very differently. Salt and citrus juice extract moisture from raw bell peppers and diced red onion through osmosis. Within a few hours, those crisp vegetables begin releasing water into the bottom of the container. If left unmanaged, a vibrant lunch transforms into a watery pool that softens chicken and dilutes flavor.
Professional meal preppers circumvent this issue by salting the diced vegetables in a colander for 15 minutes before tossing them with the meat, patting them dry with paper towels. Alternatively, whisking the lime juice with a quarter-teaspoon of ground chia seed or a splash of dijon mustard creates a light suspension that clings to the shredded chicken without running off.
