Antimicrobial fortified powders for wheat flour
Enhance wheat flour shelf-life with antimicrobial fortified powders using natural bioactive compounds like ginger extracts and peptides from seaweeds. This innovation targets bacteria such as coli O157:H7, ensuring high antimicrobial activity, whiteness, and anticaking effects without altering flavor.
Overview
The antimicrobial fortified powders for wheat flour aim to significantly extend the shelf-life of wheat flour by incorporating natural bioactive compounds with strong antimicrobial properties. These powders are designed to combat bacterial growth, particularly coli O157:H7, which is a common issue in wheat flour storage. By adding 0.1 to 5% of this fortified powder, the quality and safety of wheat flour are enhanced, potentially increasing revenue for major companies.
Technical specifications
Key features:
- Natural bioactive compounds: Utilizes ginger extracts and seaweed-derived peptides known for their potent antimicrobial activity.
- Encapsulation technique: Employs spray drying with materials like maltodextrin or cellulose to create a protective shell, masking unwanted colors and flavors while preserving antimicrobial efficacy.
- Fine particle distribution: Produces particulates with a diameter of 2 to 7 micrometers, ensuring effective integration and distribution in wheat flour.
- Comprehensive testing: Evaluated for color, flavor, antimicrobial activity, size, and adhesion to ensure optimal performance.
Technology readiness level
Currently, this technology is at TRL 2, with ongoing validation efforts focusing on identifying the most effective natural compounds, determining the minimum effective concentration, and testing under various storage conditions to ensure prolonged efficacy against bacterial growth.
