How to identify the quality of dog food? The color of dog food depends on the raw materials. The color of animal raw materials is darker than that of plant raw materials. There should be no chemically synthesized flavorings in dog food, so good dog food exudes The taste of raw materials; high-quality dog ​​food will properly maintain the original state of some raw materials, while inferior quality will be ground too finely to cover up.

1. Look at the color

The color of dog food mainly depends on the type of raw materials used, which are two major categories: animal raw materials and plant raw materials. The color of animal raw materials is darker than that of plant raw materials.

Both types of raw materials can provide the main nutrients such as protein and fat required for dog food. However, the nutritional differences are very different. Generally speaking, animal ingredients are easier to absorb and the cost is relatively high. Therefore, animal ingredients are used The quality of dog food produced mainly from raw materials is better, and the color is slightly darker, darker brown.

The use of plant-based raw materials (such as extensive use of corn) can reduce the cost of dog food, but this is at the expense of the absorption rate of dog food. In comparison, the latter is slightly lighter in color.

2. Smell the smell

Dog food is different from human food. There should be no chemically synthesized flavorings in dog food, so it will generally exude a natural flavor.

Since high-quality dog ​​food uses fresh meat as the main raw material, it will have a more obvious natural meat flavor, such as mutton or fish.

In order to cover up the overly strong taste of plant grains, low-quality dog ​​food adds too many artificial flavors, making the dog food smell unusually fragrant.

The other is because it uses more grains, so it only smells like grains.

3. Touch the particle structure

Studies have shown that keeping the interior of dog food in a coarse and granular shape will increase palatability and promote canine digestion and absorption. To identify the quality of dog food, you can break the dog food particles apart.

Since the raw materials used in high-quality dog ​​food are real and rigorous, in order to facilitate the dog's eating, high-quality dog ​​food usually maintains the original state of some raw materials. Therefore, when you open a piece of high-quality dog ​​food, you can see There are tiny shadows of raw materials in them.

Low-quality dog ​​food is usually ground too finely to cover up the lack of quality of its raw materials due to poor material standards and even being very different from what is advertised.

IV. Calculate test weight

Generally speaking, the grain structure of high-quality dog ​​food is relatively tight and compact, the grain structure is full and not sparse, and the bulk density will be correspondingly higher.

Low-end dog food uses mostly low-quality raw materials, so the dog food produced will naturally be loose and have a low bulk density. Therefore, if the dog food of the same weight appears larger, it is more worthy of suspicion whether it is over-expanded.
