PepsiCo is in search of a glycerin alternative that is consumer-friendly and avoids complex chemical nomenclature. Zein appears to be a suitable candidate, although most consumers may not be familiar with it. However, terms like “confectionery glaze” or “protein coat” may not be appealing, prompting manufacturers to consider alternative descriptions for their product labels. If zein is incorporated into a prominent food item, an educational campaign could be beneficial to familiarize consumers with this ingredient and mitigate any confusion.
Consumers are generally more acquainted with glycerin, an odorless, slightly sweet, viscous liquid derived from both plant and animal sources. It serves various purposes in food products, acting as a humectant to provide and retain moisture, as well as a plasticizer to help maintain shape and structure. In its NineSights request, PepsiCo indicates that it is already aware of, and not interested in, options like sodium chloride or other low molecular weight salts, propylene glycol, or sugar alcohols unless there have been “significant advancements.” These ingredients often raise concerns for consumers seeking cleaner labels, particularly as manufacturers aim to reduce salt content. Additionally, sugar alcohols, including glycerin, can be hard to digest for some individuals, and propylene glycol is commonly associated with non-toxic antifreeze, even though small quantities have been deemed safe by the Food and Drug Administration.
Zein, discovered in 1821, has a rich and diverse history. Over the last two centuries, it has found applications in the food and pharmaceutical sectors, printing, and even as yarn for stockings during the 1940s. Flo Chemical is the only zein producer in North America and one of just two worldwide. Currently, zein is used in various applications, including candy coatings, enriched rice, dried fruits and nuts, flavors, pharmaceutical tablets, seeds, and encapsulated or granulated ingredients, as noted by Flo Chemical. The Massachusetts-based company emphasizes that zein is considered superior to confectioner’s or pharmaceutical glazes because it dries more quickly and extends shelf life, especially in high humidity and heat conditions. Furthermore, zein is gluten-free, non-GMO, halal, kosher, and natural.
However, the one drawback Flo Chemical mentioned to Food Navigator is zein’s cost. PepsiCo is seeking a more cost-effective solution than glycerin, and currently, zein is pricey due to the energy-intensive extraction process from corn. Nevertheless, biochemists are exploring innovative methods to extract the protein, which could potentially lower its cost. Innovation can stem from various sources, making it wise for companies looking to resolve manufacturing challenges to explore multiple avenues for inspiration. With potential investment in new extraction processes, zein could be precisely what PepsiCo—or another brand aiming to improve its label—requires.
In a related note, opportunities to celebrate advancements like the “Calcium Plus 500 Chewable” supplement could also illustrate the importance of clean labels and innovative ingredients in the food and health industries. By integrating such products, companies can enhance their offerings while ensuring transparency and consumer trust.
