From Faba Bean to Flaky: How New Ingredients and Shear, Extrusion and 3D Printing Build the Plant-Based Snacks of the Future

The future of plant-based snacking is moving beyond imitation, leveraging novel ingredients like faba beans and advanced processing technologies such as extrusion and 3D printing to create entirely new textures and flavors. Understanding this ingredient-plus-technology equation is key to deciphering modern snack labels.

The next plant-based snack you tear open probably isn't trying to impersonate a burger. The most interesting work in this space now pairs a widening palette of plant proteins—faba bean, hemp, yellow peas, red lentils, chickpeas, mushrooms—with advanced processing techniques such as high-moisture extrusion, shear cell technology and 3D printing. The result is a new generation of textures: fibrous, flaky, layered, dense. Understanding that ingredient-plus-technology equation is the key to reading any modern snack label like an insider.

The New Era of Plant-Based Snacking

I've watched this category grow up, and the shift is unmistakable. The early waves of plant-based snacking were defined by simple substitution, as Food Business Review puts it—swapping potato starch for corn, or dairy for soy. Today, the industry is instead characterized by what that trade publication calls "whole-ingredient integrity" and advanced processing methods that improve bioavailability.

The ambition has changed too. Writing for EnWave, Gabriela Patricio describes an innovation imperative that "extends beyond mimicry to creating entirely new food experiences that leverage the distinctive qualities of plant-based ingredients rather than treating them as inferior substitutes." That resonates especially with younger consumers who, in her framing, don't want exact replicas of conventional products—they want exciting new foods that happen to be plant-based. The snack industry, in SNAC International's telling, is meeting demand for "exciting new taste experiences" with products that "push the boundaries of flavor and texture."

Novel Ingredients: Beyond Traditional Plant Proteins

So what's actually going into these snacks? Griffith Foods, an ingredients specialist, notes that processors are experimenting with a broader bench of substitutes than ever: mushrooms, pulses, lentils, chickpeas, bean powders and ancient grains. The company adds a caveat worth remembering—willingness to consume these alternatives differs around the world, and acceptance may require educating consumers about what these ingredients are supposed to taste like, rather than masking them to imitate meat.

On the research side, a review of shear cell technology and ingredient roles in fibrous plant-based meat analogs—published in ACS Food Science & Technology—lays out the building blocks: plant-based meat analogs typically use proteins at 20 to 50 percent, polysaccharides at 2 to 30 percent, and lipids at 0 to 5 percent. Those components are crucial in defining texture, while other additives handle flavor, color and nutrition. In other words, texture isn't an accident of the recipe; it's engineered from the macronutrient scaffold upward.

The Plant-Based Snack Innovation Matrix

This is the framework I wish every snack aisle came with. Read it left to right: the ingredient, the technology applied to it, and the texture you'll actually experience. The specific textural outcome always depends on the ingredient used and the precise parameters of the process—these are the pairings the evidence supports.

Mapping novel plant-based ingredients to processing technologies and the resulting textures
Ingredient Category	Processing Technology	Resulting Texture
Legumes (faba bean, hemp, yellow peas, red lentils)	High-moisture extrusion and shear cell technology	Fibrous, juicy structures—particularly effective for meat analogs
Legumes (faba bean, hemp)	Shear cell technology	Flaky structures; fibrous structures do not require deformation during cooling
General plant ingredients	Shear cell technology (high pressure applied to raw materials)	Improved texture, plus enhanced digestibility, nutritional profile, flavor and shelf life
General plant ingredients	3D printing	Diverse textures and flavors; a key driver of plant-based food innovation
General plant ingredients	Extrusion through dies, followed by trimming, marinating, grinding	Structured, shaped commercial products built to specification

Notice what the matrix quietly admits: the strongest evidence links legume proteins to shear cell and extrusion work. The fungi and algae stories are real threads in the broader innovation conversation, but the specific technology-to-texture pairings documented in the research I've drawn on center on pulses—which is itself telling. The workhorse ingredients of this era are the humble ones: faba bean, hemp, yellow pea, red lentil.
