Every year, July is celebrated as Ice Cream Month, a month-long tribute to one of the world's most beloved desserts. It's the perfect excuse to enjoy a scoop (or three) of your favourite flavour.
The tradition, however, has an interesting history. In 1984, Ronald Reagan played a pivotal role in establishing National Ice Cream Month by signing a joint resolution proclaiming the celebration. His proclamation recognised ice cream's popularity across the United States and the World, helping to cement a sweet tradition that continues to this day.
While flavour preferences vary from person to person, the appeal of frozen dairy products goes far beyond taste alone. The smoothness of the texture, the aroma released as the product begins to melt, the appearance of the scoop, and even the sound of a crisp chocolate coating cracking all contribute to the overall eating experience.
This is where sensory evaluation plays a vital role. Sensory science is the systematic assessment of food using our senses: sight, smell, taste, touch, and, in some cases, hearing. In the frozen dairy industry, sensory evaluation helps manufacturers understand how consumers perceive products and ensures that quality remains consistent from batch to batch.
As consumer demand continues to evolve, with interest in lower-sugar formulations, plant-based alternatives, and functional ingredients, sensory evaluation has become more important than ever. It ensures that innovation does not come at the expense of the enjoyable eating experience that consumers expect from frozen desserts.
In sensory evaluation, specifically in frozen dairy products, we look at a number of things:
- Appearance: colour, uniformity, air incorporation, ice crystal visibility
- Aroma: dairy notes, vanilla, chocolate, fruit, off-flavours
- Texture and mouthfeel: creaminess, smoothness, iciness, gumminess, firmness, chewiness
- Flavour: sweetness, dairy richness, flavour balance, taints
- Meltdown characteristics: melting rate, shape retention, separation
By assessing appearance, aroma, texture, flavour, and melting characteristics, manufacturers can ensure that every scoop delivers the quality and enjoyment consumers expect. So, as you celebrate Ice Cream Month this July, take a moment to appreciate more than just your favourite flavour. Consider the creaminess, the aroma, the way it melts, and the overall experience that makes each bite so satisfying. Behind every delicious scoop is a combination of food science, sensory expertise, and product development, all working together to create the frozen treats we know and love.
