Embodiment 1

[0024] The present invention is a kind of method that utilizes swimming crab by-product to produce seasoning sauce, chitosan and organic fertilizer, comprises the following steps:

[0025] (1) Protein extraction: Add 0.4 kg of portunus processing by-products containing large pieces of crab meat, such as the feet, crab shells, and viscera of swimming crabs, and 1.2 L of citric acid solution with a mass concentration of 0.5% in a high-temperature reaction kettle, and react The temperature and pressure of the kettle were rapidly increased to 140°C and 1.0 MPa, kept at a pressure of 60 minutes, cooled to room temperature and released, and filtered with gauze to obtain protein extract and filter residue;

[0026] (2) Preparation of seasoning sauce: The protein extract obtained in step (1) was vacuum concentrated to about 200 ml (solid content about 10%) (the basic components and amino acid composition test results of the protein extract concentrate were shown in Table 1 and Table 2...

Embodiment 2

[0031] The present invention is a kind of method that utilizes swimming crab by-product to produce seasoning sauce, chitosan and organic fertilizer, comprises the following steps:

[0032] (1) Protein extraction: Add 0.25 kg of portunus processing by-products containing large pieces of crab meat, such as the feet, crab shells, and viscera of swimming crabs, and 1.25 L of citric acid solution with a mass concentration of 0.1% in a high-temperature reaction kettle, and react The temperature and pressure of the kettle were rapidly increased to 170°C and 5.0 MPa, kept at the heat preservation pressure for 20 minutes, cooled to room temperature and released, and filtered with gauze to obtain the protein extract and filter residue;

[0033] (2) Preparation of seasoning sauce: The protein extract obtained in step (1) was vacuum concentrated to about 100 ml (solid content was about 15%) (the detection results of the basic components and amino acid composition of the protein extract con...

Embodiment 3

[0038] The present invention is a kind of method that utilizes swimming crab by-product to produce seasoning sauce, chitosan and organic fertilizer, comprises the following steps:

[0039] (1) Protein extraction: Add 0.3 kg of portunus processing by-products containing large pieces of crab meat, such as the feet, crab shells, and viscera of swimming crabs, and 1.2 L of citric acid solution with a mass concentration of 0.3% in a high-temperature reaction kettle, and react The temperature and pressure of the kettle were rapidly increased to 160°C and 3.0 MPa, kept at the pressure for 40 minutes, cooled to room temperature and released, and filtered with gauze to obtain the protein extract and filter residue;

[0040] (2) Preparation of seasoning sauce: The protein extract obtained in step (1) was vacuum concentrated to about 125 ml (solid content was about 12.5%) (the detection results of the basic components and amino acid composition of the protein extract concentrate were show...

Abstract

The invention discloses a method for producing seasoning sauce, chitosan and organic fertilizers by utilizing byproducts of swimming crabs. The method for producing the seasoning sauce, the chitosan and the organic fertilizers by utilizing the byproducts of the swimming crabs comprises the following technological processes of taking byproducts of swimming crabs as a raw material; successively performing protein extraction and decalcification on the byproducts of the swimming crabs by using high-temperature high-pressure citric acid solutions of different mass concentrations; carrying out pectinase treatment and high-temperature high-pressure alkaline water treatment so as to prepare chitosan; preparing crab-flavor seasoning sauce by utilizing the extracted protein; and preparing liquid organic fertilizers by utilizing the waste water after the high-temperature high-pressure treatment. The technology of the invention improves disadvantages of traditional technologies, namely insufficient utilization of the raw materials from the byproducts of the swimming crabs; and thus, waste discharge during the extraction and preparation processes is decreased so as to reduce production costs. The extracted chitosan can further be used as an intermediate raw material for novel functional food research and development.

Description

technical field [0001] The invention relates to the field of aquatic product processing, in particular to a method for preparing crab-flavored seasoning sauce, chitosan and liquid organic fertilizer by using high-temperature and high-pressure water auxiliary treatment and enzymolysis to extract protein from swimming crab by-products. Background technique [0002] my country is rich in swimming crab resources, and the total output of fishing and breeding in 2016 has exceeded 600,000 tons. The processed products of Portunus mainly use the crab meat under the chest shell and in Da'ao to produce canned crab meat. A large number of by-products such as crab feet, crab shells and viscera will inevitably be produced during processing. Therefore, the research on comprehensive processing technology of portunus leftovers has received extensive attention. [0003] At present, the by-products of swimming crab processing are mainly used to prepare chitin. However, in the traditional ch...
