Yogurts Cycle Test
Firmness, cyclic strength
This application study presents a cyclic test method which breaks down the structure of yogurt. Three different types of yogurt were tested to demonstrate the method: Siggi’s No Fat Raspberry Yogurt, Stonyfield Organic Low Fat Raspberry Yogurt, and Stonyfield O’Soy Soy Vanilla Yogurt. A custom sequence was used to cycle through the yogurt. A TA-18 ½” ball probe was inserted into the yogurt 25 mm from the base of the container within 30 seconds from removal from the refrigerator. The test was the initiated 90 seconds later which allowed the yogurt to settle. The sequence then cycled up 10 mm and down 10 mm from the starting position 10 times.
