Hypothesis
The intensity of color and specific colorimetric parameters significantly influence consumer acceptability of beetroot and tomato juices.
Conclusion
Darker juices generally received higher ratings for color, indicating that color plays a crucial role in consumer acceptance.
Supporting Evidence

- Color significantly influences initial product acceptance.
- Consumers showed varied preferences across different sensory categories.
Takeaway
People like darker beetroot and tomato juices more because they think they look better.
