The application of phycocyanin in acidic beverages (such as fruit juices, tea drinks, yogurts, etc.) is rapidly gaining popularity. Its unique natural blue color and clean label attributes have become key factors for product differentiation. The following are specific recent application cases and technical analyses:
I. Popular Market Application Cases
1. Hema's "White Horse Prince Soup" Composite Fruit and Vegetable Juice (Launched in October 2025)
- Product Form: A fruit and vegetable juice beverage formulated with spirulina juice (liquid form of phycocyanin), apple juice, guava juice, lime juice, etc.
- Application Highlight: Utilizes phycocyanin to present a turquoise appearance, promoting a "light burden" and "high aesthetic" concept. Over 6,000 people tried it within 5 days of launch.
2. Hema's "Heart of the Ocean Yogurt Smoothie" (Launched in 2026)
- Product Form: Refrigerated dairy product, sea salt lychee flavor, with 200mg of phycocyanin powder added per cup.
- Application Highlight: Extends the use of phycocyanin from the fruit/vegetable juice scene to chilled dairy/light desserts, using the blue color to enhance new product recognition.
3. Freshly Made Tea Drinks and Desserts
- Starbucks "Mountain Style Milk Series": Uses phycocyanin powder or phycocyanin milk cap in matcha jelly frappuccinos/tea lattes to create a "visual cooling" effect.
- "Louxia Yogurt's Lychee Phycocyanin Snowball Cheese": Incorporates phycocyanin into yogurt shaved ice, paired with lychee fruit, creating a "sky blue" visual.
- Wagas "Worry-Free Blue": Phycocyanin yogurt paired with blueberry anthocyanins, emphasizing the functional benefit of relieving eye fatigue.
4. Solid Beverages and Functional Drinks
- Glomoon "Moonlight Blue Latte": Vanilla phycocyanin latte combined with sour jujube seed, black goji berry, etc., promoting sleep aid functionality.
- U.S. Kor Shots Organic Superfood Natural Hydration Drink: Adds phycocyanin, emphasizing sports hydration and energy maintenance.
II. Technological Breakthroughs: Overcoming Stability Challenges in Acidic Environments
Traditional phycocyanin is prone to fading and precipitation in acidic beverages with pH < 4. The following are recent breakthrough solutions:
1. New Raw Materials: Low-pH Stable Phycocyanin
- Everzure Galdieria®: Jointly developed by Givaudan and Fermentalg, fermented and extracted from Galdieria sulphuraria. Approved by the FDA in May 2025, its low pH stability allows for use in acidic foods like juices, jams, and pasteurized products.
2. Formulation and Process Innovation
- Post-Addition Process: Adding phycocyanin and mixing thoroughly after yogurt fermentation and solidification are complete, avoiding damage to the protein structure.
- Complexation Technology: Research shows that forming a complex (UPP) between phycocyanin and phlorotannin can significantly improve stability in acidic environments and enhance the antioxidant properties of yogurt.
III. Key Application Points and Trends
- Color Control: In yogurt, adding 0.1g of phycocyanin per liter yields minty green, while 0.8g yields a fresh blue color.
- Clean Label: Phycocyanin is one of the few natural blue pigments certified by the FDA. In Europe and the US, it can be used as a "color-rich food" without usage limits.
- Cross-Industry Integration: Expanding from beverages and dairy into bakery, confectionery, health products, and even daily chemicals, becoming a core component of "natural color solutions."
Summary: The application of phycocyanin in acidic beverages has evolved from early "conceptual addition" to mature productization and technological innovation. Brands successfully create hit products through the combination of "visual appeal + clean label + functional implication." Meanwhile, breakthroughs in new stable raw materials (like Galdieria sulphuraria extract) and color-protecting complexation technologies are continuously expanding its application boundaries in acidic systems.
