Embodiment Construction

[0030] (1) Select the harvest period: June to October is the period when Spartina alterniflora grows faster in this area. It can be harvested from July and August to December. Harvest during this period has a large biomass and rich nutrients. When harvesting, according to the astronomical tidal law, select Spartina at a higher elevation in the supratidal zone for harvesting during the neap period, so as to improve harvesting efficiency and reduce harvesting costs;

[0031] (2) Washing and chopping: wash the soil on the harvested Spartina alterniflora with clear water, and cut the cleaned Spartina alterniflora into 2-5 cm fragments with a pulverizer;

[0032] (3) Extraction and concentration of Spartina alterniflora mineral liquid (BML): put the Spartina alterniflora segment treated in (2) into extraction and concentration equipment to process it into a BML extract with a density of 1.2-1.4. The generated water vapor is used for extraction for recycling;

[0033] (4) Natural ...

Abstract

The present invention belongs to the field of ecological cultivation technology, and is production process and application of nutritious feed coloring agent. The present invention produces healthful and safe natural feed coloring agent with Spartina alterniflora as one exotic species, and the natural feed coloring agent is used to replace chemically synthesized coloring agent added into feed. The present invention is significant in ensuring food safety and promoting the health development of breeding industry.

Description

1. Technical field [0001] The invention belongs to the technical field of ecological breeding, and specifically relates to a production method and application of a nutritional coloring agent for feeding. 2. Background technology [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, my country's aquaculture industry has also achieved unprecedented development. People not only pay attention to the nutrition of food, but also pay special attention to the color of animal food. Although the body color of animals is mainly determined by heritage factors, its body color (the color of skin, egg yolk, feathers, muscles and carapace, etc.) is mainly produced by carotenoids; animals can transfer pigments in food, transformed and manifested in itself. Due to artificial feeding, especially under the conditions of high-density intensive breeding and rapid growth, the color of the feed cannot meet the needs, and the color ...
