Embodiment 1

[0027] A method for desalting shrimp shells under ultrasound, comprising the following steps:

[0028] S1: breaking the shrimp shell into particles with a particle size of 0.85-3 mm to obtain shrimp shell powder;

[0029] S2: adding distilled water to the shrimp shell powder to obtain a shrimp shell powder soaking liquid, heating and soaking the shrimp shell powder soaking liquid at a constant temperature and stirring to obtain a heated shrimp shell powder soaking liquid, the soaking time is 20 to 80 minutes, The heating temperature is 55-75°C, and the mass ratio of the soaking liquid to the shrimp shell powder is 8:1-14:1;

[0030] S3: Perform ultrasonic treatment on the heated shrimp shell powder soaking liquid obtained in step S2, the ultrasonic frequency is 37kHZ, and the ultrasonic treatment time is 10-20 minutes.

[0031] S4: Suction-filtering and drying the soaking liquid of shrimp shell powder after ultrasonication in S3 to obtain desalted shrimp shell powder.

Embodiment 2

[0033] The shrimp shell desalination method refers to Example 1, preferably in that the soaking time in step S2 is 20 minutes.

Embodiment 3

[0035] The shrimp shell desalination method refers to Example 1, preferably the heating temperature in step S2 is 55°C.

Abstract

The invention provides a shrimp shell desalination method under ultrasounds. The method comprises following steps that firstly, shrimp shells are broken into particles with the particle diameter being0.85 to 3 mm, and shrimp shell powder is obtained; a soaking solution is added into the shrimp shell powder to obtain a shrimp shell powder soaking solution, the shrimp shell powder soaking solutionis subjected to constant-temperature heating, soaking and stirring, and the heated shrimp shell powder soaking solution is obtained; the soaking time is 20 minutes, the heating temperature is 55 DEG C, the mass ratio of the soaking solution to the shrimp shell powder is 8:1, the heated shrimp shell powder soaking solution obtained in the S2 is subjected to ultrasonic treatment, the ultrasonic frequency is 37 kHZ, and the ultrasonic time is 10 minutes. Suction filtration drying is carried out, and shrimp shell powder obtained after desalination is obtained. The shrimp shell desalination rate can reach 91.36%, after desalination, chloride and crude protein in the shrimp shells can be obviously decreased, calcium, astacin, chitin and the like are not lost, the treatment time is obviously quickened, and the method can serve as the rapid pre-treatment method for comprehensive use of calcium, astacin, chitin and the like.

Description

technical field [0001] The invention relates to a method for processing aquatic products, in particular to a method for rapidly desalting shrimp shells under ultrasonic waves. Background technique [0002] In 2016, the total output of marine cultured prawns in my country was 1.27 million tons, and the output of caught prawns was 172,300 tons. Wastes such as shrimp heads and shells produced in the processing of prawns account for about 30% to 40% of the weight of the shrimp body. Studies have shown that shrimp shells are rich in active substances such as biological calcium, chitin, chitosan, and astaxanthin. Therefore, it is of great significance to carry out research on the comprehensive utilization of shrimp shells and industrial application to reduce environmental pollution and increase product added value. [0003] Most of the leftovers such as shrimp shells of seawater shrimp contain high salt content, which is not conducive to the comprehensive utilization of subsequen...
