2017 Ingredient Trends to Watch for Food, Drinks, and Dietary Supplements: Plant Protein vs. Dairy Protein

Tensions between dairy proteins and plant proteins are heating up, but which category stands to gain the most in 2017?

In one form or another, protein frequently finds its way onto our annual list of ingredients to watch. But after years of warily eyeing each other from across the room, dairy proteins and plant proteins may be headed toward new levels of tension in 2017.

To start with, the latest sales figures for plant protein and whey protein (a dominant player in the dairy-protein space) tell strikingly different stories. After years of slowing growth, whey protein actually experienced shrinking year-over-year sales this past year. SPINS reports that whey protein, when used as the only protein source in a product, saw sales decrease by 8.6% in the last year to reach $317.8 million.1 Plant-protein sales, on the other hand, continued to grow at a steady clip, both when used alone and in combination with animal proteins.

Sales number like those are likely one reason why the dairy industry is fighting back against plant-based milks, at least. In December, 32 members of Congress-many of whom hail from milk-producing states-sent a letter to FDA requesting the agency take action against plant-based drinks bearing the term milk. Pointing to the slumping sales of dairy milk, the Congressmen said plant-based products “misbranded” as milk mislead consumers and are “a violation of milk’s standard of identity.”

But even without the dairy-protein industry taking defensive steps, the plant-protein world still has its fair share of challenges to overcome. In a recent Nutritional Outlook webcast on protein and the sports-nutrition market, Julie Daoust, PhD, research and development manager for plant-foods brand Vega, explained that despite the many new plant-protein sources on the market, there is still work to be done when it comes to taste and texture. Plant proteins may have poor solubility, gritty mouthfeel, or bitter aftertaste, and often lack established supply chains to ensure stable production.

There’s also the question of which audience a protein product is trying to reach. While plant proteins may be attractive to vegans, vegetarians, and environmentally conscious consumers, many hardcore athletes still see plant proteins as inferior to dairy proteins like whey, and are therefore unlikely to abandon dairy anytime soon, Eleanor Dwyer, research analyst for Euromonitor, explained in the same webcast.

Yet, even with the slumping standalone sales for whey protein, not all the signs are negative for whey. For instance, sales of whey protein when used alone in products bearing a “grassfed” claim grew by 15.3% last year to reach more than $5.2 million. Scott Dicker, natural products researcher for SPINS, says this may just suggest that consumers have “evolving standards” in their approach to whey protein.

Will plant protein continue to climb the sales charts and steal ground from dairy protein, or will dairy protein be able to use its entrenched position on the market to keep plant-based alternatives at bay? Or, could blends of animal and plant proteins finally come into their own and put their adversarial past to rest? We’ll just have to stick it out through 2017 to find out.
