Problems solved by technology

Although the addition of alum can significantly improve the storage quality of jellyfish, it will cause excessive aluminum residues in jellyfish, and the continuous accumulation of aluminum in the human body will cause problems such as neurotoxicity, bone toxicity, and immune toxicity. Therefore, dealumination is required before edible processing
The traditional water immersion dealumination time needs more than 24 hours, and the aluminum residue still exceeds the national food safety standard; the current existing technologies include acid soaking dealumination method and compound solution soaking dealumination method, although both can significantly reduce the aluminum residues, but the process takes a long time and the product quality is poor

Embodiment 1

[0015] The technical scheme of the present invention is used to process the salted jellyfish skins purchased from the market with the traditional three-aluminum process, and determine the residual amount of aluminum therein.

[0016] A processing method for fast dealumination of salted jellyfish, the steps of which include cleaning, ultrasonic-assisted immersion in a mixed solution of acetic acid and calcium propionate and hot water blanching, and the specific steps are as follows:

[0017] 1) Cleaning: Wash the salted jellyfish with water to remove impurities and cut into pieces.

[0018] 2) Ultrasonic-assisted immersion in a mixed solution of acetic acid and calcium propionate: soak the above-mentioned salted jellyfish in a mixed solution of 0.6% acetic acid and calcium propionate at a material-to-liquid ratio of 1:7, and place it in an ultrasonic device for ultrasonic assistance. For dealumination, the ultrasonic power is 200W, the ultrasonic frequency is 25kHZ, the ultraso...

Abstract

The invention discloses a processing method for rapid aluminum removal from pickled flame jellyfishm, and belongs to the technical field of aquatic product food processing. The method includes a cleaning step, a step of soaking utilizing an acetic acid-calcium propionate mixture solution under ultrasonic wave assistance, and a blanching step utilizing hot water. An ultrasonic cavitation function is combined in the method, thus obviously promoting dissolution of aluminum ions. Compared with traditional water soaking methods, the method has advantages of short aluminum removal time, a high efficiency, capability of improving food safety, and capability of allowing processed pickled flame jellyfish to have quality consistent with quality of products processed by traditional water soaking methods.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a processing method for rapid dealumination of salted jellyfish. Background technique [0002] Fresh jellyfish has high water content and is easy to decompose and autolyze. After being caught, it needs to be processed by "three alum" before storage. Although the addition of alum can significantly improve the storage quality of jellyfish, it will cause excessive aluminum residues in jellyfish, and the continuous accumulation of aluminum in the human body will cause problems such as neurotoxicity, bone toxicity, and immune toxicity. Therefore, dealumination is required before edible processing . The traditional water immersion dealumination time needs more than 24 hours, and the aluminum residue still exceeds the national food safety standard; the current existing technologies include acid soaking dealumination method and compound solution soaking dealumination ...
