A new study out of The Ohio State University suggests this might be the case, courtesy of a novel two-step fermentation process developed to tackle the not-so-enticing odors typically associated with these products. As reported by Ohio State News, the team's approach has been shown to remove between 95 to 99% of the key offending smells, a significant leap over the one-stage methods previously in play.
Plant-based products have a knack for emitting a bouquet that many find off-putting — think beany, grassy, or cereal-like scents. This matters, Sheryl Barringer, a professor in food science and technology at Ohio State, told Ohio State News, especially since "smell greatly influences flavor perception." It's a key reason why consumers might shy away from healthier options. And while plant-based diets are on the upswing, nobody wants to pinch their nose while taking a bite.
It turns out that adding a second fermentation step to the production of the plant-based proteins doesn't just cut down on the funky smells — it also doesn't drive up cost or drag out production time, per Ohio State. This could spell good news for those looking to shift to a more sustainable, health-conscious, and potentially allergen-friendly diet without sacrificing taste or breaking the bank.
Here's the science bit: the first fermentation stage uses beneficial bacteria, Lactobacillus plantarum, to break down the compounds behind those less-than-desirable odors. The follow-up stage harnesses a traditional yogurt culture to wrap up the fermentation process and introduce more palatable aromas. Manpreet Kaur, lead author of the study and a PhD student, noted to Ohio State News, "The only thing changed is how we utilize the bacteria."
Not all additives made a dent in the deodorizing process, however. Ingredients like allulose seemed to boost the bacteria's effectiveness, while others, like pectin, xanthan gum, and oil, didn't have a substantial impact. This research, part of a broader push for eco-friendly and healthier food sources, has the potential, according to the researchers, to drive the popularity of plant-based proteins through not just scientific innovation but also improved sensory experience.
"There’s a real focus on people wanting to be healthier and more environmentally conscious, and a push for plant-based products instead of meat and dairy products," Barringer emphasized to Ohio State News. The findings, which also involved co-author Charlotte Gray from Ohio State, are a smorgasbord of hope that our culinary futures might just be as savory as they are sustainable.
