Natural preservatives from fermented side stream by-products

Overview

Green Spot Technologies has developed an innovative approach to create natural preservatives using side streams from the food industry. By employing solid state fermentation processes, traditionally used in food storage, these side streams are transformed into cost-effective and environmentally friendly preservative ingredients. This process not only extends the shelf life of various food products but also contributes to a reduction in CO2 emissions. These natural preservatives are designed to seamlessly integrate into existing food products without altering taste or texture, making them a versatile solution for food manufacturers.

Technical specifications

• Utilizes solid state fermentation and lactofermentation techniques
• Converts food industry side streams into preservative ingredients
• Ingredients can increase the shelf life of products like bread and tomato sauce
• Works effectively even with acid-tolerant yeasts
• Ingredients maintain color, taste, and functionality, which can be adjusted based on application

Technology readiness level

The technology is currently at TRL 5, having been validated at the laboratory scale with documented proof of concept for applications such as extending the shelf life of bread. The next steps involve scaling up production and exploring further applications in collaboration with industry partners.
