Highly Stable Natural Astaxanthin Enhances Salmon's Uniform Color

In the Atlantic salmon farming industry, color has become the primary visual indicator for assessing quality. Surveys reveal that over 85% of consumers directly associate a uniform, bright orange-red hue with salmon freshness and high quality. This visual impression directly influences purchasing decisions and product premium pricing. However, behind this market-defining color lies a long-standing technical challenge plaguing the industry—color inconsistency.

The industry currently faces severe challenges:

◆ Market losses: Approximately 30% of farmed salmon are downgraded due to uneven coloration, resulting in significant annual economic losses for farming enterprises

◆ Technical bottlenecks: Traditional astaxanthin raw materials prove fragile during feed processing, with high-temperature extrusion degrading an average of 25-40% of active components

◆ Quality Fluctuations: Oxidative deactivation during storage and absorption variations during farming result in “rainbow-like” color differences within the same batch of salmon

“Uneven coloring not only impacts immediate profits but also damages the brand reputation aquaculture companies have built over the long term,” stated the Quality Director of a major salmon farming enterprise. “We need to ensure stable and consistent coloring effects starting from the raw material level.”

This industry pain point highlights the market's urgent need for innovative astaxanthin ingredients—requiring not only superior coloring capabilities but also stability proven throughout the entire supply chain. Driven by this industry insight, Green Spring Technology is committed to providing fundamental solutions through technological innovation.

1 Redefining Astaxanthin Stability Standards in Aquafeeds

Through continuous R&D, our team systematically uncovered the key mechanism affecting salmon coloration via advanced molecular dynamics simulations and experimental validation: structural integrity loss of astaxanthin molecules during feed processing and storage is the root cause of unstable coloring. Building on this significant discovery, Green Spring Technology has successfully developed an industry-revolutionizing stabilized astaxanthin solution. This breakthrough overcomes traditional technical limitations, bringing revolutionary progress to the aquafeed industry.

1.1 Innovative Protection Mechanism: Molecular-Level Protection Technology System

Our proprietary molecular protection system employs multi-layered, three-dimensional conformation protection technology to achieve comprehensive safeguarding of astaxanthin's active components:

1.1.1 Structural Stability Breakthrough

· Utilizing nano-level three-dimensional encapsulation technology to form a dense protective layer on the astaxanthin molecule surface

· Constructing stable three-dimensional spatial protective structures through molecular self-assembly technology

· Employing specialized interfacial modifiers to enhance the bonding strength between the protective layer and astaxanthin molecules

1.1.2 Enhanced Environmental Tolerance

· 42% higher than traditional products, far exceeding industry averages

· Active ingredient retention remains above 95% after multiple pelleting processes

1.2.2 Breakthrough in Storage Stability

· Accelerated storage testing (40°C/75% RH) extends product activity half-life to 18 months

· Activity retention duration is 2.3 times longer than conventional products

· Under ambient storage conditions, quality remains stable for 24 months

1.2.3 Significant Application Enhancement

· Field data shows salmon color uniformity standard deviation reduced from 1.8 to 0.6

· Roche color chart scoring stability improved by 65%, with significantly reduced batch-to-batch variation

· Coloring efficiency increased by 40%, reducing required dosage by 30% to achieve equivalent color depth

1.3 Application Advantages: Exceptional Performance from Lab to Farm

A technical director at a major aquaculture enterprise stated after a 6-month trial: "Using this product, our salmon not only achieved significant improvements in color uniformity—reaching a 94% premium-grade rate—but also demonstrated markedly enhanced health. Stress response incidence during cultivation decreased by 25%, while feed conversion rate improved by 8%. This breakthrough in stability has truly resolved our long-standing pain points, granting our products stronger competitiveness in the premium market.“

This innovative technology not only represents a major advancement in astaxanthin raw material technology but also provides the aquaculture industry with a comprehensive quality control solution. By achieving end-to-end stability control from raw materials to finished products, we are helping aquaculture enterprises transition from ”experience-based farming“ to ”precision farming," driving the entire industry toward standardization and normalization.

Our R&D team continues to refine this technological framework and is currently developing a second-generation intelligent controlled-release system, which is expected to further enhance product performance and create greater value for the industry.
