Small bubbles for natural aroma

Lea Pokorny and Pascal Guillet, two ETH Pioneer Fellows, developed a novel aroma powder improving food, home-care and cosmetic products.

For what kind of applications is your aroma powder intended?

microPow aroma powder improves the stability and enhances the perception of aroma and flavour compounds in end products. It will be applied in food products such as ice-cream, coffee or snacks, in cosmetic products such as shampoo, washing emulsions and creams and in home-care products such as liquid laundry detergent.

How does this work and what are the benefits of working with the microfoam based microPow?

microPow is a micro-foamed, fat-continuous powder with incorporated aroma and flavour compounds. The foam-based microstructure stabilizes contained aromas during processing and storage and enhances the aroma release compared to pure aroma compounds. Furthermore, the microfoamed structure allows incorporation of volatile (gas soluble), fat-soluble and suspended aromas which generates a well rounded flavour profile compared to conventional carrier systems for aromas and flavours.

Is there anything similar existing in the market?

Currently, manufacturers use two approaches to preserve the quailty and aroma of food products and counteract the degradation of aromas and flavours during processing and storage. Firstly, aroma and flavour compounds in food products can be stabilized by additives such as emulsifiers, which is strongly opposing the current, ever rising consumer demand for more natural, additive-free food products. A second option is the addition of artificial aroma and flavour compounds to food products or the application of elevated concentrations of natural aromas and flavours, which leads to higher manufacturing costs for producers.

Today, a lot of people care about environmentally friendly production, especially in cosmetic products. Does microPow support this?

microPow absolutely supports this and will actively contribute towards more environmentally friendly products in food, home-care and cosmetics. microPow aroma powders are additive-free (contain no emulsifiers or stabilizers) allowing natural, but at the same time convenient food products, are produced by an energy efficient process and are based on an organic, fat-based composition. Application of microPow powders to cosmetics, home-care and food products will bring highly stable, natural aromas and structures to a broad product range.

What are your goals for next year?

We will further push the boundaries of our technology in collaboration with partners from food, cosmetics and home-care industries with the goal to have working and scalable prototype products by the end of 2018. In the beginning of 2019, the scaled-up microPow process will be running and enabling the production of certified (food / cosmetic grade) microPow powders and implementation into industrial products.

In October / November 2018 we are participating in the 2018 Kickstart Accelerator as one of six teams selected for the food vertical. Our aim is to incorporate our company by end of 2018 and secure the funding required to build up the scaled microPow production process.
