LS means were compared using Scheffe’s Multiple Comparison Procedure. Small case superscripts within species and large case superscripts between species not sharing the same letter are significantly different (). Produce (based on availability) was fridge-stored (4°C) for 3 and/or 6 days. —: not detected.
