Researchers are making strides in the quest to create cat food that even the most finicky felines can’t resist. At the forefront of this effort are scientists from Northeast Agricultural University’s College of Food Science and the Shanghai Institute of Technology’s School of Perfume and Aroma Technology. They have enlisted a panel of ten discerning cats to pinpoint the flavor compounds that will revolutionize feline dining.
If you live with cats, you’re familiar with the challenge of enticing them to eat. Cats’ heightened sense of smell plays a crucial role in their food preferences. Unlike humans, felines have a heightened sensitivity to umami (savory) flavors but lack the ability to taste sweetness. This sensory nuance complicates efforts to create cat food that is both nutritious and appealing.
To tackle this, the research team is testing various cat food flavor sprays to determine which are most appealing to cats. They developed these sprays by homogenizing and heat-treating chicken livers and then breaking down the proteins with enzymes to create four distinct attractants. From these, they identified over 50 flavor compounds, ranging from tropical and floral to sweaty and rubbery.
The study involved coating commercially available cat kibble with chicken fat and one of the four chicken liver attractants. This was compared to a control food treated with a different commercial attractant. Observations focused on which food the cats preferred and their consumption patterns throughout the day.
The findings reveal that cats show a marked preference for foods with flavor sprays rich in free amino acids, which enhance savory and fatty flavors. The research highlights that foods with mushroom and fatty flavors were notably favored, while those with more acidic and sweet profiles were less popular.
Understanding which flavor compounds appeal to cats could lead to the development of tastier foods, potentially reducing food waste and ensuring that cats receive the necessary nutrition for a healthy life. This research aims to strike a balance between creating palatable cat food and maintaining its nutritional value.
Future studies are expected to focus on integrating the preferred flavors with optimal nutrient profiles, advancing the development of cat foods that are both delicious and nutritionally complete.
