Abstract
The invention relates to the technical field of aquatic product byproduct processing, in particular to a method for separating calcium-containing protein powder from shrimp leftovers, which comprises the following steps: s1, soaking the shrimp leftovers in a mixed solution of ethanol (containing lactic acid) with high concentration of over 90% for 72-120 h; s2, sieving the shrimp leftovers soaked in the step S1 through a 20-mesh sieve, and collecting calcium-containing protein slurry; and S3, adjusting the pH value of the protein slurry to 6-7, and freeze-drying to obtain the calcium-containing protein powder. The invention adopts the mixed solution of high-concentration ethanol (containing lactic acid) to treat the shrimp leftovers such as the shrimp shells, is beneficial to the shedding of protein and the precipitation of calcium in the shrimp shells, and is beneficial to improving the utilization value of the shrimp leftovers such as the shrimp shells.
Description
Technical Field
The invention relates to the technical field of aquatic product byproduct processing, in particular to a method for separating calcium-containing protein powder from shrimp leftovers.
Technical Field
During the processing of shrimps, a large amount of leftovers such as shrimp heads, shrimp shells and the like can be generated, and the shrimp leftovers account for about 30-40% of the weight of the shrimp body. The fresh shrimp heads and shells contain about 5% of chitin, more than 10% of protein and the like. The shrimp shell protein contains 8 kinds of amino acids essential for human body and is protein with high nutritive value. The shrimp shell calcium carbonate is a good food calcium source, and can prevent and treat osteoporosis after being eaten for a long time. The calcium-containing protein separated from the shrimp leftovers can be used in food, and is favorable for high-value utilization of the shrimp leftovers.
Disclosure of Invention
The invention aims to overcome the problems in the prior art and provides a method for separating calcium-containing protein powder from shrimp leftovers.
The purpose of the invention is realized by the following technical scheme:
a method for separating calcium-containing protein powder from shrimp leftovers comprises the following steps:
s1, soaking shrimp leftovers in a mixed solution of ethanol and lactic acid for 72-120 hours;
s2, sieving the shrimp leftovers soaked in the step S1 through a 20-mesh sieve, and collecting protein slurry;
and S3, adjusting the pH value of the protein slurry to 6-7, and freeze-drying to obtain the calcium-containing protein powder.
Preferably, in step S1, the ethanol and lactic acid mixed solution has an ethanol concentration of 90% or more and a lactic acid content of 5% to 15%.
Compared with the prior art, the invention has the following technical effects:
the invention discloses a method for separating calcium-containing protein powder from shrimp leftovers, which adopts a mixed solution of high-concentration ethanol (containing lactic acid) to treat the shrimp leftovers such as shrimp shells and the like, is favorable for the falling off of protein and the separation of calcium in the shrimp shells, and is favorable for improving the utilization value of the shrimp leftovers such as the shrimp shells and the like.

Unless otherwise specified, the devices used in this example are all conventional experimental devices, the materials and reagents used are commercially available, and the experimental method without specific description is also a conventional experimental method.
Example 1
A method for separating calcium-containing protein powder from shrimp leftovers comprises the following steps:
s1, soaking shrimp leftovers in a mixed solution of ethanol and lactic acid for 72 hours;
s2, sieving the shrimp leftovers soaked in the step S1 through a 20-mesh sieve, and collecting protein slurry;
and S3, adjusting the pH value of the protein slurry to 6-7, and freeze-drying to obtain the calcium-containing protein powder.
Preferably, in step S1, the ethanol and lactic acid mixed solution has an ethanol concentration of 90% or more and a lactic acid content of 10%.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and not for limiting the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
