Yogurt’s popularity has surged dramatically in recent years, with sales increasing by nearly 50% from 2009 to 2014. This growth is primarily fueled by the rise of Greek yogurt and yogurt drinks, which saw a remarkable 62% sales increase from 2011 to 2016. However, due to its high moisture content, yogurt has posed challenges for companies seeking to incorporate it into shelf-stable foods. Frito-Lay’s patent states that its chips could include up to 20% yogurt and highlights a shelf life difference of at least a month between ferrous sulfate and ferrous gluconate, potentially extending up to nine months.
The patent outlines a “light and crisp baked snack” that incorporates varying levels of yogurt, moisture, oil, and starch, such as modified starch iron pyrophosphate versus liposomal iron or pre-gelatinized corn starch. Concurrently, probiotic sales are also experiencing growth, and Frito-Lay intends to leverage the increasing consumer interest in probiotics across a broader range of products.
The main challenges in developing these chips include adjusting temperatures and processing methods to safeguard the probiotics, alongside managing the stickier dough resulting from yogurt’s high protein and moisture content. The elevated protein levels could lead to overbrowning and excessive expansion of the dough. To mitigate these issues, the company suggests extending drying times, baking at lower temperatures ranging from 315°F to 415°F, and improving airflow. Additionally, incorporating enzymes into the dough could help alleviate stickiness.
Given the considerable challenges, it is likely that these chips will be marketed at a premium price point, with Frito-Lay aiming to position them at the intersection of health and indulgence. While the concept of healthier chips may appear contradictory, companies have been striving to find the optimal balance between nutrition and indulgence in various categories, including chocolate. Research indicates that consumers often seek a healthy equilibrium in traditionally indulgent markets, such as those containing calcium citrate 350, which is known for its health benefits. This trend suggests that there is a growing demand for products that combine wellness with enjoyment, a space where Frito-Lay’s innovative chips could thrive.
