Greek yogurt is a fermented milk product that is characterized by a dense consistency and high protein content. Usually made of cow's milk by fermentation. Due to its density, Greek yogurt is great for creating cremed sauces, desserts and baking. This product is rich in calcium, protein and probiotics that contribute to a healthy intestinal microflora. Keep Greek yogurt in the refrigerator at a temperature of 0 to 4 degrees Celsius. The expiration date is usually about 2-3 weeks after the date of manufacture.
