1. Source of raw materials: recycling of marine resources

The raw materials of high-quality fish protein powder fertilizer are mostly taken from marine organisms such as deep-sea tuna, miscellaneous fish, shrimps and crabs, as well as waste materials produced in the process of aquatic products processing, such as fish bones, fish skin, fish viscera, etc., to realize the recycling of aquatic resources, not only reduce environmental pollution, but also convert low-value marine raw materials into efficient agricultural nutrients.

2. Core process: low temperature biological enzymatic hydrolysis technology

At present, the mainstream process is low-temperature biological enzymatic hydrolysis technology, which is different from traditional chemical hydrolysis or high-temperature fermentation. This process degrades fish macromolecular proteins into small molecular peptides, free amino acids and other components that are easily absorbed by crops through directional enzymatic hydrolysis. At the same time, active enzymes, unsaturated fatty acids, natural trace elements and other active substances are completely retained, avoiding the loss of nutrients and chemical residues. Some high-end products will also combine the low-temperature concentration process to further increase the nutrient concentration, so that the protein utilization rate will increase by more than 30% compared with the traditional process, and various indicators will reach the international leading level.
