What Makes Some Functional Ingredients Taste Better Than Others?

New research on Chardonnay grape marc suggests the answer may have less to do with individual compounds and more to do with how those compounds interact within a whole-food matrix.

Taste is often discussed as a marketing consideration. In reality, it is frequently a formulation challenge.

Many ingredients associated with health benefits including fibers, botanical extracts, polyphenol-rich compounds, and plant-based ingredients can introduce bitterness, astringency, off-notes, or undesirable mouthfeel. These sensory characteristics often force formulators to rely on sweeteners, flavor systems, bitterness blockers, or other corrective strategies before a product is ready for market.

That reality helps explain why a recently published study examining the taste chemistry of Chardonnay grape marc attracted attention across the functional food and dietary supplement industries.

The study, published in the Journal of Agricultural and Food Chemistry, used sensory-directed fractionation and analytical techniques to investigate the compounds responsible for the sensory characteristics of Chardonnay grape marc, the whole-fruit ingredient used in WellVine.

The findings provide new insight into a question that extends well beyond a single ingredient:

Looking Beyond Individual Compounds

Traditionally, scientists often evaluate ingredients by identifying their individual chemical constituents.

If an ingredient contains compounds known to contribute bitterness or astringency, formulators may reasonably expect those characteristics to appear in finished products.

However, food systems are rarely that simple.

Researchers identified 39 taste-active compounds within Chardonnay grape marc, including naturally occurring sugars, organic acids, and flavonol compounds associated with various sensory characteristics. Yet despite the presence of compounds that might typically be expected to contribute bitterness or astringency, the ingredient's observed sensory profile was characterized by mild sweetness, bright acidity, smooth astringency, and relatively low bitterness.

The "Matrix Effect" Explained

One of the most interesting themes emerging from the study is the concept often referred to as the food matrix effect.

In a whole-food ingredient system, fibers, polyphenols, organic acids, sugars, and other naturally occurring compounds remain associated within a complex structure that evolved together in nature. These compounds do not exist in isolation. They interact physically and chemically in ways that can influence taste perception, release characteristics, mouthfeel, and overall sensory experience.

By contrast, isolated ingredients are frequently evaluated and used as individual components.

The new research suggests that understanding these interactions may be just as important as understanding the compounds themselves.

For formulators, that distinction has important implications.

Why Taste Matters More Than Many People Realize

In functional products, efficacy may drive the first conversation.

Taste often determines whether consumers come back.

A product can have an impressive scientific story, but if consumers dislike the sensory experience, long-term success becomes much more difficult.

This is especially relevant in categories such as:

• Functional beverages
• Wellness powders
• Fiber supplements
• Botanical formulations
• Polyphenol-rich products
• Clean-label foods and snacks

Many of these products require significant formulation effort to manage bitterness, dryness, chalkiness, or astringency.

As a result, sensory performance can influence everything from development timelines and ingredient costs to consumer acceptance and repeat purchase behavior.

What Researchers Found in Chardonnay Marc

The study linked sweetness primarily to naturally occurring sugars and acidity to several organic acids. Certain flavonol compounds contributed to astringency.

Importantly, researchers were able to construct a taste simulation model that closely reflected the ingredient's observed sensory characteristics.

This type of work provides a more detailed understanding of why an ingredient behaves the way it does rather than simply describing what it tastes like.

For ingredient developers and formulation teams, that mechanistic understanding can be valuable because it provides a scientific framework for predicting performance across different applications.

Implications for Functional Product Development

The study was not designed to evaluate consumer purchasing behavior, clinical outcomes, or commercial performance.

However, it does contribute to a growing body of evidence suggesting that whole-food ingredient systems may offer sensory advantages that are not always apparent when evaluating individual compounds in isolation.

For formulators, this raises several interesting questions:

• 1
  Can whole-food ingredient systems reduce the need for flavor correction?
• 2
  Are some sensory challenges better addressed through ingredient architecture than through masking systems?
• 3
  Could matrix interactions help explain differences in consumer acceptance among seemingly similar ingredients?
• 4
  Might future ingredient development place greater emphasis on whole-food functionality rather than isolated compounds?

While additional research will be needed to answer these questions fully, the current findings provide a useful starting point.

A Shift in How We Think About Functional Ingredients

For years, functional ingredient development has often focused on identifying and isolating individual compounds associated with specific benefits.

The Chardonnay grape marc study points toward a broader perspective.

Rather than asking only what compounds an ingredient contains, researchers are increasingly asking how those compounds behave together within a complete food system.

That shift may ultimately prove important not only for sensory science but also for formulation strategy, product development, and consumer experience.

As the functional food and beverage industry continues to evolve, understanding the relationship between taste chemistry and whole-food structure may become just as important as understanding the compounds themselves.
