Summary

Collagen is hot—but formulating with it isn’t easy. Whether it’s marine or bovine, collagen peptides bring big benefits for skin, joints, and performance—but they also drag along fishy, beefy, or bitter off-notes that can wreck your clean-label profile. In this article, we explore how Icon Foods’ ThauSweet™ DRM and VRM modulators give formulators the power to smooth those rough edges, balance bioavailability with taste, and create collagen-enriched products consumers actually enjoy!

Food and beverage formulators — let’s talk collagen. Whether you’re pumping up protein in a keto latte, functional gummy, or RTD elixir for skin, joints, and bones, collagen peptides are riding the wellness wave hard—and for good reason. But if you’ve worked with them (and I’m guessing you have), you know they work, but they don’t exactly play nice on the palate.

We’re diving deep into the marine and bovine varieties—because those are the workhorses of the category—and exploring how to navigate their bioavailability, efficacy, and those pesky off-notes that haunt your flavor profile like ghosts in a clean-label machine. And yes, we’ll talk solutions: ThauSweet™ DRM and ThauSweet™ VRM are here to make peace between taste and function.

Marine v. Bovine Collagen Peptides: Battle of the Bioavailable Beasts

Property Marine Collagen Bovine Collagen
Source Wild-caught or farmed fish skin/scales Grass-fed bovine hide or cartilage
Type Primarily Type I (skin, bone, ligaments) Mostly Type I & III (skin, joints, gut)
Molecular Weight 1–3 kDa 3–6 kDa
Bioavailability High (smaller peptides, faster absorption) Moderate (still efficient, but slower)
Solubility Excellent in cold and hot applications Good, but slower in cold liquids
Flavor Off-Notes Fishy, briny, slightly metallic Meaty, broth-like, barnyardy
Cost per KG $$$ $$

Bottom line? Marine collagen wins on bioavailability and solubility but comes with a strong flavor tax. Bovine collagen is cost-effective and blends well in denser formats like bars and shakes—but it brings a heavy-handed umami funk that needs to be dealt with.

The Off-Note Struggle is Real

Let’s not sugarcoat it (though we kinda will in a moment): both marine and bovine collagen have flavor baggage. The fishy halo around marine collagen can crash the clean citrus vibe of your sparkling functional water. And that beefy backend of bovine collagen? Try masking it in a vanilla protein shake without ending up in the savory aisle.

These off-notes are driven by residual amino acids like glycine, proline, and hydroxyproline, along with traces of lipids and minerals from their animal sources. Heat processing intensifies them. Flavoring systems can help, but when you’re targeting clean labellow sugar, and functional efficacy, your toolkit gets real small, real fast.

Enter: ThauSweet™ DRM & VRM — Your Off-Note Assassins

You don’t need to hide behind a wall of erythritol and natural flavors to fix your collagen conundrum. You need precision tools. That’s where ThauSweet™ DRM and ThauSweet™ VRM come in—next-gen sweetness modulators designed for food scientists who want clean label control without compromise.

ThauSweet™ DRM (Deep Rich Modulator)

  • Best for: Dairy, RTDs, and chocolate-flavored applications
  • Strengths: Smooths out lingering protein bitterness, fills in mouthfeel, rounds out cocoa and malt notes
  • Usage level: 25–80 ppm (0.0025–0.008%) depending on protein load
  • Pairs well with: MonkSweet™ LS4, allulose, MonkSweet V50

ThauSweet™ VRM (Vibrant Receptor Modulator)

  • Best for: Fruity, citrus, tropical, and clear beverage systems
  • Strengths: Attenuates metallic off-notes and fishy/iodine top-notes from marine collagen, brightens acid-forward profiles
  • Usage level: 20–60 ppm (0.002–0.006%) depending on application pH
  • Pairs well with: SteviaSweet™ RM95D, erythritol, and citrus terpenes

These aren’t flavorings, bitter blockers, or masking agents—they’re receptor activators, dialing down bitterness and sourness by modulating the TAS2R and TAS1R receptor pathways on the tongue. The result? You get clean sweetness, enhanced fruitiness, and a smoother finish the lingers past off-notes.

Best Applications & Dosage for Collagen Peptides

Here’s a cheat sheet for application-specific collagen inclusion and where ThauSweet™ earns its keep:

Application Collagen Type Inclusion Rate Challenge ThauSweet™ Solution
RTD Protein Beverages Bovine or Marine 10–15g/serving Off-flavors intensify with heat DRM (70 ppm) or VRM (60 ppm)
Functional Gummies Bovine 5–8g/serving Bitter edge, long aftertaste DRM (50 ppm)
Clear Beauty Beverages Marine 5–10g/serving Metallic/fishy notes VRM (40 ppm)
Powdered Drink Mixes Bovine or Marine 10–20g/serving Needs masking without bulk DRM (60 ppm) or VRM (50 ppm)
High-Protein Bars Bovine 5–15g/serving Brothy/meaty off-notes DRM (80 ppm)

Pro tip: VRM is pH sensitive and works best in systems below pH 4.5 (citrus-forward, kombucha, etc.). DRM loves creamier, richer systems like dairy, oat, and nut-based blends.
