Green Spring Technology Unveils Acid-Stable Phycocyanin, Overcoming Key Formulation Challenge

In elpursuit of clean labels ynatural wellness, every food ybeverage innovator has faced this dilemma: when your meticulously developed blue lemelsoda finally completes its formulation, only to witness that vibrant natural blue gradually lose its luster in an acidic environment, ultimately turning cloudy and dull; When you prepare to launch a refreshing blueberry-flavored yogurt, only to discover that under pH testing, elideal blue hue transforms into a disappointing precipitate.

This is precisely the “acidic problem” that has plagued the industry for years—traditional phycocyanin rapidly denatures in acidic environments below pH 4.0, leading to flocculation, precipitation, and irreversible discoloration. This technical barrier has acted as an insurmountable chasm, confining natural blue pigment applications to a narrow neutral pH range. Consequently, the most market-promising categories—fruit juices, carbonated soft drinks, and acidic dairy products—have become “lost territories” for natural color innovation.

Countless brands have been forced to make difficult choices between “visual appeal” and “natural ingredients,” either reverting to synthetic colorants or abandoning product creativity.

However, this industry stalemate is about to be shattered.

We proudly announce that Green Spring Technology has successfully developed a revolutionary “acid-resistant” phycocyanin through core innovation. Engineered to conquer acidic environments, it overcomes the core technical challenge of phycocyanin instability at low pH levels. This breakthrough means brands can now effortlessly impart stable, clear, and long-lasting natural blue hues to acidic beverages and foods without compromise.

Part I: Green Spring Technology's Phycocyanin Stability Technology

1. Core Technology: Lvquan's “Acid-Resistant Anchoring” Technology

Traditional phycocyanin becomes unstable in acidic environments because its protein structure undergoes spatial conformatielchanges upon encountering hydrogen ions (H⁺). This causes the pigment group to detach, leading to flocculation, precipitation, and fading.

Green Spring Technology's proprietary “Acid-Resistant Anchoring” tecnologíafundamentally resolves this challenge through dual technical approaches: protein engineering modification and polysaccharide complex encapsulation:

· Molecular Structure Stabilization: Precise protein engineering optimizes charge distribution on the phycocyanin surface, enabling it to maintain stable spatial conformation in acidic environments and effectively resist H⁺ ion attacks.

· Three-dimensional protective network: Specific polysaccharide molecules form a dense molecular network on the phycocyanin surface. This “protective shield” not only blocks direct H⁺ contact with the protein via steric hindrance but also further stabilizes the chromophore structure through intermolecular interactions.

The breakthrough of this technology lies in its fundamental stabilization of phycocyanin in acidic environments at the molecular level, rather than merely masking the issue.

Key Data Supporting Claims:

· Exceptional pH Stability

  · Maintains complete solubility across a broad pH range of 3.0–7.0 without any flocculation or precipitation

  · In a simulated beverage system at pH=3.5, solution transmittance remained above 95% after 30 days at room temperature

· Sustained color retention

  · Accelerated testing shows >85% color value retention after 90 days storage at 40°C in an acidic beverage (pH=3.2)

  · Comparative tests show traditional phycocyanin products exhibit <30% color retention under identical conditions

· Exceptional process adaptability

  · Withstands conventional pasteurization (72°C, 15 seconds)

  · Achieves >92% color retention under HTST (High Temperature Short Time) processing

2. Four Key Benefits for Brands

Based on these technological breakthroughs, Green Spring Technology's “acid-resistant” phycocyanin solution delivers tangible benefits to brand clients: 

Benefit 1: Expanding Innovation Horizons

Natural blue pigments can now be stably applied to core categories previously considered “off-limits,” including carbonated beverages, juices, sports drinks, acidic dairy products, jams, and confectionery. Brands no longer need to compromise product concepts for stability, unleashing full creative potential.

Benefit 2: Elevating Product Quality

It completely resolves precipitation and fading issues in acidic systems, ensuring products maintain crystal-clear transparency and consistently vibrant color throughout their shelf life—from production to consumer hands. This significantly enhances brand professionalism and consumer trust.

Benefit 3: Strengthening Clean Label

Our “acid-resistant” phycocyanin is derived from natural spirulina, containing no synthetic components. A single ingredient simultaneously fulfills the dual market demands for “natural coloring” and “clean label,” helping brands establish a differentiated advantage in intense market competition.

Benefit 4: Simplified Production Process

The product exhibits excellent water solubility and compatibility, requiring no adjustments to existing formulation processes for pH control or the addition of special stabilizers. This significantly reduces production complexity and innovation costs.

Part II: Applications of Acid-Resistant Phycocyanin Ingredients

Leveraging Green Spring Technology's exceptional “acid-resistant” phycocyanin, we have established deep collaborations with multiple industry-leading brands, transforming technological innovation into market-competitive products.
