OSF Flavors, experts of masking flavors for plant proteins

A single serving of plant protein powder can contain up to 24 grams of protein, placing it in the same league as other animal protein powders like whey, a widely utilized protein in the sports nutrition market. Pea, soy, hemp, and brown rice are the primary plant protein sources in the market.

However, plant proteins pose a challenge to the food industry due to their often strong and unpleasant aftertaste, a concern for consumers. This aftertaste is commonly described as “beany,” “earthy,” or even “green.” In response to this challenge, OSF Flavors has developed a specialized masking flavor technology aimed at masking these undesirable notes and enhancing the overall taste of products incorporating plant proteins.

Development of a masking flavor

As a flavor manufacturer, it is common for our customers to send us the “base” of their functional products, like the plant protein powder, for example. Thanks to OSF Flavors’ GC-MS technology, we can characterize the flavor and aroma profile of this specific vegan protein, which can change drastically as the origin and methods used to obtain the protein varies between brands. A panel of flavorists then tastes the protein to establish a precise organoleptic profile of the protein to mask.

This is the first step in the development of a specific masking flavor.


The flavorists are then able to use their expertise to select specific flavor building blocks to create the most appropriate masking agent for the application.These flavor building blocks are developed by studying, analyzing and tasting plant proteins from around the world. Each flavor component is complex and targets one specific unwanted aftertaste of the vegan protein. For example, some of them work well to mask bitterness while others help to suppress the “earthy” off-notes. These flavor building blocks are then combined in specific ratios which results in a masking flavor effective for the specific protein to be masked.
