Embodiment 1

[0019] Recovery method of amino acid in sardine canned fish broth waste liquid:

[0020] (1) sardine canned fish soup waste liquid is extracted twice with n-hexane of 2 times the mass for degreasing, the extracted upper layer solution is recovered with n-hexane, and the extracted lower layer aqueous solution is collected for use;

[0021] (2) Add the lower aqueous solution part to the treated strong acid styrene type cation exchange resin, wash the column with distilled water at a flow rate of 60 drops / min, first wash away inorganic salts, heavy metals and other substances, and use it as the effluent of the column When the reaction with 2% ninhydrin is positive, stop washing, use 3% ammonia water to elute slowly, control the flow rate to 80 drops / min, and collect the eluate, when the eluate is mixed with 2% ninhydrin When the reaction is negative, stop the elution;

[0022] (3) Concentrating the eluent collected in step (2) by rotary evaporation to remove ammonia gas and part...

Embodiment 2

[0025] Recovery method of amino acid in sardine canned fish broth waste liquid:

[0026] (1) sardine canned fish soup waste liquid is extracted twice with n-hexane of 2.5 times the mass for degreasing, and n-hexane is recovered from the extracted upper layer solution, and the extracted lower layer aqueous solution is collected for use;

[0027] (2) Add the lower aqueous solution part to the treated strong acidic styrene type cation exchange resin, wash the column with distilled water at a flow rate of 55 drops / min, first wash away inorganic salts, heavy metals and other substances, and use it as the effluent of the column When the reaction with 2% ninhydrin is positive, stop washing, and use 3.5% ammonia water to elute slowly, control the flow rate to 75 drops / min, and collect the eluate, when the eluate is mixed with 2% ninhydrin When the reaction is negative, stop the elution;

[0028] (3) Concentrating the eluent collected in step (2) by rotary evaporation to remove ammoni...

Embodiment 3

[0031] Recovery method of amino acid in sardine canned fish broth waste liquid:

[0032] (1) sardine canned fish soup waste liquid is extracted twice with n-hexane of 2 times the mass for degreasing, the extracted upper layer solution is recovered with n-hexane, and the extracted lower layer aqueous solution is collected for use;

[0033] (2) Add the aqueous solution of the lower layer to the treated strong acidic styrene-type cation exchange resin, wash the column with distilled water at a flow rate of 65 drops / min, first wash away inorganic salts, heavy metals and other substances, and use it as the effluent of the column When the reaction with 2% ninhydrin is positive, stop washing, and use 3% ammonia water to elute slowly, control the flow rate to be 85 drops / min, and collect the eluate, when the eluate is mixed with 2% ninhydrin When the reaction is negative, stop the elution;

Abstract

The invention discloses a method for recovering amino acids in canned sardine processing fish soup waste liquid and application thereof and belongs to the technical field of foods. The compound aminoacids in the fish soup waste liquid are obtained by using an ion exchange resin method, and the method has the advantages of simple technology and easy industrial production. The obtained compound amino acids can be used for being processed into an amino acid oral liquid, or being added in foods such as biscuits, breads, cakes and condiments as nutritional ingredients, and the food nutrition and flavor are enhanced. The method can greatly improve the utilization rate of resources, reduce environmental pollution, increase the added value of the fish soup waste liquid, and increase the profit ofan enterprise.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for recovering amino acids from sardine canned fish broth waste liquid and an application thereof. Background technique [0002] As the basic unit of protein, amino acid directly participates in metabolism and other physiological activities in organisms. The lack of certain amino acids in human body fluids will cause different diseases. Therefore, amino acids play a key role in maintaining and supplementing the nutrition of patients and rescuing the lives of dying patients. They are one of the indispensable nutrients in organisms. There are 20 kinds of protein amino acids, more than 400 kinds of non-protein amino acids, and thousands of kinds of their derivatives and synthetic polypeptides. Amino acids are widely used in medicine, food, health care, feed, cosmetics, pesticides, fertilizers, tanning, scientific research and other fields. [0003] Ami...
