Electronic Nose and Tongue Technology: Diverse Applications in Palatability Research & Testing

Author: Punyatoya Mohapatra

AFB has invested in cutting edge analytical technologies to assist with palatability evaluation. We posted two articles about Electronic Nose and Electronic Tongue (ENT) technology in 2013, and we have expanded the possible applications for our customers over the last four years. We have used this technique to understand the differences in our palatant makeup to provide performance to our customers, an example was our ISOEN blog posted in 2015.Today, we leverage ENT as part of a holistic, data-driven research approach that provides our customers with more insightful answers to a multitude of palatability questions related to product development and product stability.

Product Development

While two-bowl testing is still the primary way to determine palatability preference, we use ENT to identify why the pet preferred one bowl over the other. Did it taste different?  Did it smell different? Is there a particular ingredient creating an unpleasant off-note? Is there a volatile compound causing issues with palatability? ENT illuminates aroma and taste profile interactions that positively or negatively correlate to pet selection behavior. Now, our scientists systemically make formulation decisions leveraging years of data collected from ENT to accelerate time-to-market for our customers, as well as recreate specific flavor profiles that our customers desire.

Product Stability

ENT helps our customers answer stability concerns during shelf life studies by seeing changes in taste or smell over-time as compared to recently manufactured product or against a competitive benchmark. In addition, production consistency is critical to ensure a repeatable product response in pets.

Using ENT, we work closely with our customers to identify lot-to-lot and/or plant-to-plant variability that affects the final product consistency or performance differences.

ENT technology has applications across the development and distribution pipeline. In combination with traditional tools and methods, we can provide our customers with a more complete analysis and the most informed recommendations for their products.

Please sir who are your representatives in South Africa.
I am building a new Pet Food plant and would like to know could you maybe get your opinion in our planning.
Thank you.

I am a student of electronic engineering and I always like to spend time in reading stuff related to my studies on the internet. This post is very informative for me which is about electronic nose and tongue technology. You have shared all the details about this experiment here and I will must recommend others to read this post here.

Has AFB developed or does AFB intend to develop human grade flavors?
