Ornamental demersal fish feed and preparation method thereof

Abstract

The present invention discloses an ornamental demersal fish feed and a preparation method thereof. The feed recipe consists of food-grade raw materials and does not contain any adhesives. The feed consists of the following raw materials in parts by weight: 25-30 parts of spirulina platensis, 25-30 parts of pumpkin powder, 10-15 parts of egg yolk powder, 10-15 parts of soybean lecithin, 5-10 parts of egg yolk lecithin, 1-3 parts of animal bone meal, 1-3 parts of collagen, 1-2 parts of plant lutein, 1-2 parts of compound vitamins, 0.001-0.003 part of garlic powder, 1-2 parts of lactose, 1-2 parts of glucose, and 2-3 parts of yeast powder. In addition to the fact that the recipe components all consist of food-grade raw materials, the recipe design also uses the nature of the food raw material themselves to conduct an interaction. The feed can be compressed to form a shape without adding any adhesives and low temperature molding can be achieved. The low temperature molding can effectively preserve the nutrients, avoids the loss of nutrients and the decomposition of vitamins caused by high temperature during the baking process, and enables the nutrients in the raw materials to be completely preserved.

Description

technical field [0001] The invention belongs to the field of ornamental fish feed, in particular to an ornamental benthic fish feed and a preparation method thereof. Background technique [0002] Bottom-dwelling ornamental fish species are newly emerging species in recent years, distributed throughout the Amazon River Basin in South America, and can extend as far north as Costa Rica and Panama in Central America. In this era of highlighting individuality and self-expression, traditional ornamental fish can no longer meet people's needs, and this is laying the foundation for benthic heteromorphic fish. Once it appears, it has won many aquarists for its unique shape. Now it occupies a very important position in the market, and some of them are rare varieties that people can't meet. How to raise this rare ornamental fish so that it can show the bright and bright colors in the natural environment has been a research topic for aquarists for a long time, and the choice of feeding...

AI Technical Summary

Problems solved by technology

[0003] At present, the ornamental fish feed on the market basically adopts the method of mixing the raw materials first, then making a paste with water, then cutting into small pieces and then drying at high temperature for a long time to shape, or directly adding the mixed raw materials into the extruder No matter what method is used, it cannot avoid the loss of vitamins, protein and other nutrients caused by high temperature.

In addition, in order to ensure that the fish will grab food and increase the color, the existing feed has to be added with artificial pigments and flavors to achieve the purpose of color enhancement, and in order to make the feed shape, a large amount of adhesives are added.
