Yogurt should be maintained at < 10 ºC during storage and transportation to arrest various biological and biochemical reactions (Tamime & Robinson, 1999a); however in the U.S., yogurt should be maintained at ≤ 7 ºC throughout storage and transportation (PMO, 2007). Generally, yogurt has a shelf life of 4 to 7 weeks (Chandan & O‟Rell, 2006b); however, yogurts with live and active cultures should have counts of the individual yogurt and probiotic bacteria ≥ 6 log cfu g
-1 until the end of stated shelf life (Lourens-Hattingh & Viljoen, 2001).
