Nucla: encapsulated salt-alternative for reduced sodium content
NuCla is an innovative salt-alternative using a plant-based protein complex for controlled salt release. It enhances salt flavor while reducing sodium content by 25-50% in products like sauces, sausages, and bakery items. Validated at industrial scale, it's nearing commercialization.
Overview
NuCla is a pioneering salt-alternative designed to reduce sodium intake without compromising on flavor. Utilizing an encapsulation technology that combines common salt with a non-allergenic plant-based protein, NuCla provides an initial burst of salty flavor followed by a controlled release, extending the salty taste duration. This dual mechanism allows for a 25-50% reduction in salt content across various food products, including sauces, sausages, bread, and bakery items.
Technical specifications
NuCla appears as a white powder similar to micronized salt. It forms a complex with salt and plant-based protein, allowing it to withstand manufacturing processes. Upon consumption, the encapsulated particles break to deliver an immediate salty taste, while some particles adhere to the mouth mucosa for a prolonged release. This technology has been scaled from lab to pilot to industrial levels and is currently undergoing industrial validation in various facilities.
Key features:
- Encapsulation of salt with plant-based protein
- Initial burst and prolonged release of salty flavor
- Applicable in a wide range of food products
- White powder form similar to micronized salt
Technology readiness level
NuCla is at Technology Readiness Level 6, indicating that it has been tested in relevant environments and is in the process of validation at an industrial scale. Future steps include further industrial testing, physicochemical characterization, and regulatory approval to facilitate commercialization.
About NUCAPS Nanotechnology
NUCAPS Nanotechnology is a Spanish biotechnology company that specializes in a proprietary protein-based microencapsulation technology. Founded in 2017, the company designs and produces functional ingredients by encapsulating bioactives and probiotics within microscopic, food-grade protein matrices.
