Description

technical field

[0001] The invention relates to a preparation method of fish protein biological peptide fertilizer. Background technique

[0002] In recent years, my country's marine aquatic resources have undergone tremendous changes, especially the output of freshwater fish ranks first in the world, providing my country with very rich animal protein resources, and the application of low-value fish and waste protein from processed fish appears to be particularly important. Since the mid-19th century, experts at home and abroad have been interested in the extraction and application of concentrated fish protein. This product is rich in nutrients and easy to digest. It can replace eggs and milk, and can correct the malnutrition caused by the long-term lack of protein in the body. It is widely used in important fields such as food, feed, and medicine to correct digestive enzyme disorders and relieve dyspepsia, but there is no report on related fertilizers.
