Why is yogurt a better meat tenderizer?
Yogurt tenderizes meat by using lactic acid to gently break down proteins without ruining the texture.
While vinegar and lemon juice can be too harsh, yogurt contains lactic acid that slowly softens muscle fibers and collagen. It also contains calcium, which triggers enzymes in the meat to further break down tough proteins. This process creates a melt-in-your-mouth texture common in dishes like Tandoori chicken and Middle Eastern kebabs. Unlike fruit-based marinades, yogurt works gradually to keep the meat juicy and firm.

The science of yogurt marination relies primarily on lactic acid and calcium ions. Lactic acid is a mild organic acid that lowers the pH of the meat, causing the proteins to denature and unwind slowly. Unlike the high acidity of vinegar (acetic acid) or lemon juice (citric acid), lactic acid does not turn the surface of the meat into a mushy paste.Research published in the Journal of Food Science highlights that calcium plays a critical role in this process. Calcium naturally activates calpains, which are endogenous enzymes found within the muscle tissue. These enzymes act like molecular scissors, cutting through the structural proteins and connective tissues to create a tender bite.This method has been a staple of South Asian and Middle Eastern culinary traditions for centuries. For example, the Tandoori style of cooking, which dates back to the Mughal Empire, relies on yogurt to ensure chicken remains moist in high-heat clay ovens. Modern food scientists at institutions like Cook's Illustrated have confirmed that yogurt marinades penetrate more evenly than water-based alternatives.Furthermore, the thick consistency of yogurt helps the marinade cling to the meat's surface. This creates a protective barrier that prevents moisture loss during the cooking process. The result is a chemical synergy that enhances both the physical structure and the flavor profile of the protein.
