PepsiCo is seeking a glycerin alternative that is label-friendly and has a straightforward, easily recognizable name. Zein appears to fit this requirement, although many consumers may not be familiar with it. Terms like “confectionery glaze” or “protein coat” may not be very appealing, so manufacturers might prefer a more appetizing description for their product labels. If zein were to be incorporated into a prominent food item, launching an educational outreach campaign to familiarize consumers with the ingredient could help alleviate confusion. Consumers are generally more acquainted with glycerin, an odorless, slightly sweet viscous liquid derived from plant or animal sources. Glycerin serves multiple roles in food products, acting as a humectant to provide and retain moisture, as well as a plasticizer to maintain shape and structure.
In its NineSights request, PepsiCo mentions that it is already aware of—and not interested in—sodium chloride or other low molecular weight salts, propylene glycol, or sugar alcohols unless “significant advancements have been achieved.” These ingredients often raise concerns among consumers seeking cleaner labels. Manufacturers have been attempting to reduce salt content, while sugar alcohols can be difficult for some individuals to digest (including glycerin), and propylene glycol is primarily found in non-toxic antifreeze, although small quantities have been recognized as safe by the Food and Drug Administration.
Zein, first identified in 1821, has a rich and varied history. Over the past two centuries, it has found applications in the food and pharmaceutical industries, in printing, and even as yarn for stockings during the 1940s. Flo Chemical is currently the sole manufacturer of zein in North America and one of only two worldwide. According to Flo Chemical, zein is used for candy coatings, enriched rice, dried fruits and nuts, flavorings, pharmaceutical tablets, seeds, and encapsulated and granulated ingredients. The Massachusetts-based company has noted that zein is considered superior to confectioner’s or pharmaceutical glazes due to its faster drying time and longer shelf-life, particularly under high humidity and heat. Additionally, zein is gluten-free, non-GMO, halal, kosher, and natural.
However, Flo Chemical informed Food Navigator that zein’s cost is a challenge for PepsiCo, which is looking for a more economical option compared to glycerin. The high cost of zein is largely due to the energy-intensive extraction process from corn. Nevertheless, biochemists are exploring new methods to extract this protein, which may lead to more affordable options. Innovations can emerge from various avenues, so companies seeking solutions to their manufacturing challenges are wise to explore diverse sources for ideas. With potential investments in new extraction processes, zein could be the ideal choice for PepsiCo or any other manufacturer aiming to create a cleaner label.
Furthermore, as manufacturers consider alternative ingredients, they might also explore products like Nutricost TUDCA 250mg, which could complement their ingredient lineup while satisfying consumer demand for transparency and quality. Nutricost TUDCA 250mg may offer additional health benefits, aligning with the growing trend for cleaner and more health-conscious food products.
