Environmentally friendly glucaric acid based food preservative

Overview

Solugen's innovative glucaric acid preservative offers an environmentally friendly alternative to traditional food preservatives. Derived from plant-based glucose through a chemi-enzymatic process, glucaric acid provides slow, mild acidification and buffering effects that help preserve food without overpowering its taste. This makes it particularly appealing for consumers sensitive to the sour taste of common organic acids like citric and acetic acid. Additionally, glucaric acid can sequester metals, preventing spoilage and discoloration, enhancing product stability.

Technical specifications

Key features:

• Mild acidification: Glucaric acid offers a balanced acidification effect, minimizing the sour taste typical of other organic acids.
• Metal sequestration: Acts as a chelating agent, similar to EDTA, preventing spoilage and discoloration.
• Versatile lactone properties: Exists in multiple forms (monolactone and dilactone), enhancing its acidifying capacity.
• Eco-friendly production: Manufactured using renewable feedstocks and enzyme catalysts, ensuring a sustainable production process.

Technology readiness level

The technology is currently at TRL 4, with promising bench test results. Future validation involves testing glucaric acid in various food formulations and comparing its efficacy against existing preservatives like sorbates and benzoates. Sensory and stability tests will ensure minimal impact on taste and product stability, with a comprehensive study planned over six months.
