Moist soft granulated bait feed and a preparation method thereof

Abstract

The present invention relates to moist soft granulated bait feed and a preparation method thereof. Specifically, the bait feed is prepared by controlling a pH value and water contents to make the bait feed stable in a water body so that the bait feed is not prone to collapse and scatter; and extruding and granulating materials to make the materials have a certain mass density and granulated dosage regimen characteristics, which makes the bait feed convenient to throw and easy for animals to hold. The bait feed is comprehensive in nutrition and rich in active substances. Compared with the dry granulated feed, the bait feed can avoid problems of loss of nutritional ingredients and inactivation of lactic acid and other active substances in granulating, processing, curing, drying and other process. The bait feed is easy to eat, digest and absorb, and can save resources, reduce water pollution, enhance immune resistance to disease for shrimps

Description

technical field [0001] The invention belongs to the technical field of aquatic feed and bioengineering, and in particular relates to a wet soft granular bait and a preparation method thereof. Background of the invention [0002] Moist bait (Moist Pellet) refers to solid bait with more water content (generally ≥ 20%). At present, wet baits mostly use fresh fish or fish paste, fish oil and water as wet ingredients, which are mixed with dry ingredients (fish meal, soybean meal powder, yeast, wheat flour, etc.), adhesives, minerals, vitamins and preservatives. Extruded into granules. In the 1950s, salmon were raised on wet baits in Oregon, USA. In Japan in the 1960s and 1970s, further research on more characteristic wet baits was to mix powdery compound baits with fresh baits to make wet baits with different nutritional requirements. Our country also began to explore this aspect in the early 1990s. The method is basically the same, and it is also granulated by mixing dry powd...

AI Technical Summary

Problems solved by technology

However, the above method has the following problems. Because the raw material is not fermented and denatured, it is difficult to make particles with a particle size below 1mm, and the smaller the particle, the easier it is to collapse and become unstable; the above wet bait is prone to mold due to its high moisture content during application. Deterioration, not suitable for long-term storage, nor long-distance transportation, it is okay for self-production and self-use, as a commercial bait factory, these quality problems cannot be solved, and breeding users dare not use this kind of product
