The plant-based food market no longer needs explanation. Plant-based burgers, pea protein nuggets, cheese alternatives, oat or almond beverages: plant-based products are already on the shelves of every European retail chain.
The numbers are growing, product lines are multiplying, and consumers are buying.
Yet those who formulate plant-based foods for industrial production know that the real challenge lies elsewhere: in taste, color, texture, and stability of the finished product.
A plant-based burger that “tastes like soy” stays on the shelf. One that credibly reproduces the sensory experience of meat gets repurchased.
The difference is made by the ingredients, particularly the flavorings, colorants, and functional ingredients that transform a plant protein base into a product that consumers recognize as good.
Plant-based food: why formulation is the real challenge
Unlike traditional meat or dairy products, where the raw material brings with it a significant part of the sensory profile (flavor, color, texture, juiciness), in plant-based food everything must be constructed.
Pea, soy, fava bean, wheat, or rice proteins have their own sensory profile, but it is rarely what the consumer expects from the finished product.
Plant proteins tend to have herbaceous, astringent, bitter, or earthy notes. Their texture, before processing, is far from that of ground meat or cheese. Their natural color does not resemble meat or dairy.
This is why the formulation of plant-based products requires technical work on three simultaneous fronts: taste, visual appearance, and structure.
It is not masking work. It is sensory design work: building a credible consumption experience starting from plant-based ingredients, without resorting to compromises that consumers perceive.
And this is where expertise in natural ingredients makes the difference.
The three sensory challenges of plant-based products
Masking undesirable notes
Plant proteins carry off-flavor notes: herbaceous, floury, bitter, astringent. These notes do not disappear with cooking; in some cases they intensify.
The first step in formulating any plant-based food is to neutralize or balance these perceptions without covering them with overly intense flavorings that would make the product taste artificial.
Building the target flavor profile
A plant-based burger must “taste like a burger.” A chicken alternative must have poultry and savory notes. A cheese alternative must recall dairy and aged notes.
This profile does not exist in the plant raw material: it must be built entirely through custom-formulated flavorings that reproduce the complexity of the animal original without declaring ingredients that consumers do not want to read on the label.
Consistency and juiciness
Texture is the third pillar. Consumers do not judge a burger solely by its taste: they judge it by the bite, juiciness, and mouthfeel. Functional ingredients such as fibers, thickeners, emulsifiers, and vegetable fats work together to recreate a credible structure. Without texture, the best flavoring in the world is not enough.
The role of flavorings in plant-based food
In plant-based food, flavoring is not an accessory ingredient: it is the element that defines the sensory identity of the product. The most requested flavor profiles in the sector are grilled, roasted, smoked, umami, dairy-cheese, and poultry.
Each requires specific formulations for the plant matrix, because plant proteins interact with aromatic compounds differently than animal proteins.
A flavoring that works perfectly in a beef burger may turn out completely different in a pea protein burger.
The herbaceous notes of the plant base combine with the aromatic profile and modify the overall perception. This is why savory flavorings intended for plant-based applications must be developed and tested on the specific plant matrix, not adapted from formulations designed for meat.
There is also the dual function of flavoring in plant-based products: masking undesirable notes while simultaneously building the target profile. These are two distinct tasks that the same formulation must perform in synergy.
Color and appearance: why the eye also matters in plant-based products
Color is the first sensory signal that consumers receive. In plant-based products that imitate meat, color must communicate credibility even before tasting.
A plant-based burger must have the pink-brown tone of raw meat and turn brown after cooking. A chicken alternative must be ivory-white. A salmon alternative must have the classic pink-orange color.
Achieving these results with natural ingredients requires precise coloring work. Red beet is widely used for the “blood” tone in raw plant-based burgers.
Caramel provides the brown tones of cooking. Paprika adds orange notes. But each natural colorant has its own sensitivity to pH, heat, and light, which must be managed during formulation.
For plant-based products intended for home cooking, there is an additional challenge: the color must change during cooking in a way consistent with consumer expectations.
A burger that remains the same color raw and cooked generates distrust. The savory colorants used in these applications must also be selected based on their thermal behavior.
Functional ingredients: texture, stability, and shelf life
In addition to flavorings and colorants, the formulation of plant-based foods requires a series of functional ingredients that work on the structure and preservation of the product.
Fibers and thickeners contribute to the cohesion of the mixture and the sensation of juiciness when bitten. Methylcellulose, for example, is one of the most used natural ingredients in plant-based products because it gels when heated (reversing the behavior of most thickeners), simulating the compactness of meat during cooking.
Vegetable fats (coconut, sunflower, rapeseed) provide juiciness and mouthfeel. The choice of fat type and form (solid, liquid, microencapsulated) directly affects the perception of the product’s “meaty character.”
Emulsifiers and stabilizers maintain the integrity of the matrix during shelf life, preventing phase separation, moisture loss, and texture degradation. In packaged plant-based products, stability during storage is a significant technical challenge: without animal proteins to act as a natural binder, the formulation system must compensate with targeted additives and functional ingredients.
Clean label and plant-based food: expectations and reality
Those who buy plant-based food expect a clean label. It is an almost automatic expectation: if I choose a plant-based product for health, sustainability, or ethical reasons, I expect the ingredient list to be short, understandable, and without E numbers. The formulation reality is more complex.
Building a credible sensory profile on a plant base requires more ingredients than are needed in a traditional meat-based product. The clean label challenge in plant-based products is therefore twofold: achieving a sensory result at least equivalent with a label that communicates naturalness.
The answer lies in ingredient selection. Natural flavorings compliant with EU Regulation 1334/2008, colorants of plant origin (beet, paprika, curcumin), fibers and thickeners recognizable by consumers. Clean label in plant-based food is not achieved by eliminating ingredients, but by choosing the right ones.
Bayo’s solutions for the plant-based sector
Bayo supports plant-based food manufacturers with a complete range of flavorings, colorants, and functional ingredients developed for the specificities of plant matrices.
We do not adapt formulations designed for meat: we develop aromatic profiles, color solutions, and functional blends tested on pea, soy, fava bean, and cereal proteins.
Production starts from selected raw materials, with ISO 9001 and FSSC 22000 certifications and complete traceability. Technical support includes targeted sampling, application tests on the customer’s actual matrix, and dedicated technical assistance from analysis of the target product to final validation.
For a sector where the difference between a product that gets repurchased and one that stays on the shelf is entirely in the formulation, having a partner who knows plant matrices is not an advantage: it is a prerequisite.
