Why do dogs prefer extruded dog food made by pet feed extruder machines?

While dogs' sense of taste isn't as sensitive as humans', they have a clear preference for the savory flavor of meat and the texture of food. Extruded dog food, through process control, comprehensively enhances palatability, from flavor enhancement and texture shaping to ease of feeding, ensuring every meal is a pleasant experience for dogs.

Firstly, the extrusion process brings out the natural flavor of the raw materials, creating a "meaty" aroma that dogs love. Under high temperature and pressure, the amino acids in the dog food ingredients undergo a Maillard reaction with reducing sugars. This reaction generates various flavor compounds; for example, cysteine in chicken meal reacts with glucose to produce a rich aroma similar to roasted chicken. This natural flavor is more appealing to dogs than artificial flavorings. Simultaneously, the process removes fishy-smelling substances from the raw materials, such as trimethylamine in fish meal, reducing odor through high-temperature volatilization and resulting in a purer flavor in the dog food. Compared to ordinary steaming and cooking processes, the extrusion process achieves a more complete Maillard reaction, increasing the content of flavor compounds by over 30%. Upon opening the dog food bag, you can smell the natural meaty aroma, instantly stimulating your dog's appetite.

Secondly, extruded dog food offers a rich texture that suits a dog's chewing habits. The process allows for precise control of the food's hardness and crispness by adjusting the die diameter, screw speed, and pressure of the extruder. For example, for puppies, the hardness is controlled at 10-15N, resulting in a soft, easy-to-chew texture that avoids damaging their teeth; for adult dogs, the hardness is increased to 15-20N, providing a crisp texture that satisfies their chewing needs and helps clean their teeth. Extruded dog food is also designed in various shapes, such as cylindrical or bone-shaped, to increase the fun for dogs. Some products also have chicken or fish oil added to the surface through a post-coating process, enhancing the flavor and smoothing the texture, further improving palatability.

The extrusion process also optimizes the "base flavor" of the dog food, reducing irritation. Dogs are sensitive to bitter and pungent tastes, and some plant-based ingredients, such as soybean meal, contain bitter substances. The high temperatures during extrusion break down these bitter substances, reducing the irritation of the dog food and making it more palatable for dogs. Meanwhile, the processing method ensures that the oils in the raw materials are evenly distributed throughout the kibble, avoiding the greasy feeling caused by excessive oil content in some areas, and preventing the dryness caused by insufficient oil content, resulting in a more balanced and mild flavor.

Furthermore, the ease of eating extruded kibble increases a dog's willingness to eat. The kibble size is uniform, without overly large or undersized pieces, eliminating the need for frequent adjustments to chewing patterns, making it especially suitable for senior dogs and dogs with dental problems. The microporous structure on the kibble surface allows saliva to quickly penetrate, helping to moisten the food and reducing swallowing difficulties. For puppies during teething, the crispy extruded kibble satisfies their chewing needs without harming their gums, allowing them to eat normally during this special period.
