Problems solved by technology

[0002] Since the 1990s, the total amount of aquatic products in my country has ranked first in the world year after year. Among them, tilapia has become one of the main economic sources of aquatic products due to its strong reproductive ability, fast growth cycle, strong disease resistance and resistance to coarse food; however, my country's However, the aquatic product processing industry is difficult to adapt to it. It mainly focuses on rough processing and seldom fine processing. Therefore, a large amount of waste fish materials are produced in the tilapia processing industry, mainly including fish heads, fish tails and other underutilized fish meat. Failure to be dealt with in time, resulting in a great waste of resources and economic losses
[0003] In order to further utilize these discarded protein resources, a lot of research work has been carried out at home and abroad, but they mainly focus on the extraction of some of the physiologically active substances, such as EDA, DHA, chitin, taphin, etc., but in view of my country's lagging processing and It is difficult to process and improve tilapia by-products through complex technology, so a simple scientific process is urgently needed at this stage to realize the resource utilization of tilapia processing by-products, and at the same time provide a source for the development of my country's aquatic product processing industry. a transition

Embodiment 1

[0026] The method for preparing amino acid liquid fertilizer by using tilapia processing waste provided in this example comprises the following steps: select the tilapia processing waste and stir to make fish paste, add water and compound protease BJ101 to the fish paste, and decompose after enzymatic hydrolysis Enzyme, filtered, and the obtained filtrate is refrigerated to become amino acid liquid fertilizer.

[0027] Sodium bicarbonate is added to the tilapia processing waste, and its added amount is 3% of the total mass of the tilapia processing waste.

[0028] The amount of water used is 5 times that of fish paste, and the amount of composite protease BJ101 is 0.3% of the total mass of fish paste.

[0029] Compound protease BJ is composed of neutral protease and alkaline protease in a ratio of about 1:1, purchased from Guangzhou Yulibao Enzyme Preparation Co., Ltd., and the product model is BJ101.

[0030] The enzymolysis temperature is 50°C, and the enzymolysis time is 5...

Embodiment 2

[0035] The method of using tilapia processing waste to prepare amino acid liquid fertilizer provided in this example is different from that in Example 1 in that sodium bicarbonate is added to the tilapia processing waste in an amount equal to the amount of tilapia processing waste 1% of the total mass of the substance.

[0036] The amount of water used is three times that of fish paste, and the amount of composite protease BJ101 is 0.2% of the total mass of fish paste.

[0037] The enzymolysis temperature is 45°C, and the enzymolysis time is 5.5h.

[0038] While enzymatic hydrolysis, agitation treatment is carried out.

[0039] The temperature for inactivating the enzyme is 95°C, and the time is 8 minutes.

[0040] When filtering, use medium-speed filter paper to filter, and the temperature when refrigerated is 3 °C.

Embodiment 3

[0042] The method of using tilapia processing waste to prepare amino acid liquid fertilizer provided in this example is different from that in Example 1 in that sodium bicarbonate is added to the tilapia processing waste in an amount equal to the amount of tilapia processing waste 5% of the total mass of the substance.

[0043] The amount of water used is 8 times that of fish paste, and the amount of composite protease BJ101 is 0.4% of the total mass of fish paste.

[0044] The enzymolysis temperature is 55°C, and the enzymolysis time is 4.5h.

[0045] While enzymatic hydrolysis, agitation treatment is carried out.

[0046] The temperature for inactivating the enzyme was 92°C and the time was 9 minutes.

[0047] When filtering, use medium-speed filter paper to filter, and the temperature when refrigerated is 5°C.

Abstract

The invention discloses a method for preparing a liquid amino acid liquid fertilizer from tilapia mossambica processed wastes. The method comprises the following steps of selecting the tilapia mossambica processed wastes, stirring the tilapia mossambica processed wastes into fish paste, adding water and composite protease BJ101 into the fish paste, after enzymolysis, performing enzyme deactivation, filtering the product, and refrigerating the obtained filtrate, thus obtaining the liquid amino acid liquid fertilizer. The invention also discloses the liquid amino acid liquid fertilizer prepared by the method and the application of the liquid amino acid liquid fertilizer to a soil conditioner. Due to the fact that a tilapia mossambica processed by-product is processed byenzymolysis technology, resource utilization of the tilapia mossambica processed wastes can be realized; the method is simple and low in cost; the prepared liquid amino acid liquid fertilizer is high in nutritive value and economic value and can serve as the soil conditioner to be applied to greenhouse planting soil or field soil.
