PepsiCo is in search of a glycerin substitute that is consumer-friendly and avoids lengthy and complex chemical names. Zein appears to meet these criteria, though many consumers may not recognize the term. However, alternatives like “confectionery glaze” or “protein coat” may not sound particularly appealing, prompting the manufacturer to consider a more enticing label description. If zein were incorporated into a prominent food product, an educational outreach initiative could effectively demystify the ingredient for consumers, especially since they are already more familiar with glycerin. This odorless, slightly sweet liquid derived from plant or animal sources serves various roles in food products, including as a humectant for moisture retention and as a plasticizer to maintain shape and texture.
In its NineSights request, PepsiCo clarifies that they are already acquainted with—and not interested in—sodium chloride, low molecular weight salts, propylene glycol, or sugar alcohols unless substantial advancements have been made. These ingredients often raise concerns for consumers seeking cleaner labels, as manufacturers aim to reduce salt content, sugar alcohols can be hard to digest (glycerin included), and propylene glycol, although recognized as safe by the FDA in small amounts, is primarily found in non-toxic antifreeze.
Zein, discovered in 1821, boasts a rich history, having been utilized across food and pharmaceutical sectors, for printing, and even as yarn for stockings in the 1940s. Flo Chemical is the sole manufacturer of zein in North America and one of only two globally. Presently, zein is employed as a candy coating, on enriched rice, for dried fruits and nuts, in flavors, in pharmaceutical tablets, and for encapsulated and granulated ingredients, as noted by Flo Chemical. The Massachusetts-based company asserts that zein outperforms confectioner’s and pharmaceutical glaze due to its faster drying time and longer shelf life—especially under high humidity and heat. Notably, zein is gluten-free, non-GMO, halal, kosher, and natural.
However, Flo Chemical admits that zein’s cost is a drawback for PepsiCo, which seeks a more economical alternative to glycerin. Currently, zein extraction from corn is energy-intensive, making it pricey. Nonetheless, biochemists are exploring new methods for protein extraction, which could lower costs. Innovations can emerge from various avenues, making it wise for companies facing manufacturing challenges to seek diverse ideas. With potential investments in new processes, zein could become the ideal solution for PepsiCo or another manufacturer striving to enhance their product labels, including the integration of tccm tablets, which could further optimize the product’s functionality and appeal.
