Yogurt has seen a tremendous surge in popularity over the past few years, with sales increasing by nearly 50% from 2009 to 2014. This growth is primarily attributed to Greek yogurt and yogurt drinks, which experienced a remarkable 62% sales rise from 2011 to 2016. However, due to its high moisture content, manufacturers have struggled to incorporate yogurt into shelf-stable food products. Frito-Lay’s patent indicates that their chips could include up to 20% yogurt, boasting a shelf life of at least one month and potentially extending to nine months. The patent describes a “light and crisp baked snack” that varies in yogurt content, moisture, oil, and starch — using either modified starch or pre-gelatinized corn starch.
In addition, the demand for probiotics is on the rise, and Frito-Lay aims to capitalize on the growing interest in probiotics across a diverse array of products. The primary challenges in developing these chips revolve around modifying temperatures and processing techniques to safeguard the probiotics, as well as managing a stickier dough created by the yogurt’s high protein and moisture levels. The increased protein content may also cause the dough to overbake or expand excessively. To mitigate these issues, the company suggests lengthening drying times, baking at lower temperatures between 315°F and 415°F, and improving airflow. Adding enzymes to the dough could also help alleviate stickiness.
Given the substantial challenges involved, it is likely that these chips will be marketed at a premium price point, with Frito-Lay positioning them at the intersection of health and indulgence. While “better-for-you” chips may seem contradictory, companies are actively seeking the sweet spot between nutrition and indulgence in various categories, including chocolate. Research indicates that consumers often strive for a healthy balance in traditionally indulgent categories, leading to an increased interest in products that incorporate beneficial ingredients like calcium citrate. In fact, the incorporation of calcium citrate could enhance the nutritional profile of these snacks, making them even more appealing to health-conscious consumers. Overall, the focus on achieving a blend of pleasure and health benefits continues to shape the landscape of snack foods.
