How to identify the quality of shrimp feed

There are numerous kinds of shrimp feed that are similar, and the same type of shrimp feed can also have different quality of products and the requirements for quality are also different. It is necessary to establish standards to determine the quality. It is possible to be assessed whether it is of good quality feed for shrimp is excellent or poor.

The appearance of shrimp feed

The appearance of the shrimp feed is the main factor as well as the acceptance by the market of a food item is heavily contingent on its appearance. Surfaces of top shrimp feed must be smooth and the cut should be flat and uniform in size and length is equal and the color uniform.

Water resistance of shrimp feed

If the appearance is intended to assess an “appearance” to the feed for shrimp, and that of the water resistance, it’s used to determine what is the “intension” of feed for shrimp. The shrimp remain granular after eating and on the other hand aids in the consumption of shrimp, but on the contrary, it is important to prevent the nutrients from the feed from being lost and safeguarding from water damage, encourage digestive and absorbtion of shrimps in the feed and boost the proportion of meat and feed.

The high water resistance of shrimp feed demands that the feed is completely softened in 20 to 30 minutes after the soaking process in water. There isn’t a hard core present in the feed once it has been handled by hand and it won’t expand when flattened. After a period of about 2 hours of water resistance the feed will begin to expand, without breaking or falling apart.

The rate of powdering in shrimp feed

Another crucial indicator to determine food quality is amount of powder that is used. The rate of powdering is when the same weight of food for the shrimp (500g) goes through a box that rotates for 10 minutes. And after 500 hits that simulate the pressure that shrimp feed is exposed to during transport, cooling and packing, and weighs the resultant fine powder to determine the amount of feed.

Reduced powdering rates of shrimp feed will reduce the amount of waste resulting from the dissolution of feed powders in water, safeguard the quality of water, and reduce the cost of bait and feed as well as the coefficient.

Color of shrimp’s feed

The color of the shrimp feed is not just due to the granulation process but is also affected by post-curing effect. A superior shrimp feed needs to be uniform in color as well as uniform in oil.
