Embodiment 1

[0028] Soak hijiki in water for 3.5 hours, wash, and drain; put 10g of drained hijiki into a beaker, add 200mL of water; move the beaker into an ultrasonic instrument, and ultrasonicate for 15min at an ultrasonic frequency of 25kHz , 30min, 45min, after the ultrasound is finished, clean the Hijiki with clean water, and dry it at 45°C.

Embodiment 2

[0030] Soak hijiki in clean water for 3 hours, wash and drain; put 10g of drained hijiki into a beaker, add 200mL of water; move the beaker into an ultrasonic instrument, and ultrasonicate for 15min at an ultrasonic frequency of 35kHz , 30min, 45min, after the ultrasound is finished, clean the Hijiki with clean water, and dry it at 45°C.

Embodiment 3

[0032] Soak hijiki in water for 3 hours, wash and drain; put 10g of drained hijiki into a beaker, add 200mL of water; move the beaker into an ultrasonic instrument, and ultrasonicate for 15min at an ultrasonic frequency of 40kHz , 30min, 45min, after the ultrasound is finished, clean the Hijiki with clean water, and dry it at 45°C.

Abstract

The invention discloses a sargassum fusiforme arsenic removal process which comprises (1) soaking sargassum fusiforme in water, cleaning and draining off the water; (2) soaking the sargassum fusiforme which is drained off in water, and carrying out ultrasonic processing; (3) cleaning the sargassum fusiforme with water after the ultrasonic processing is finished, and drying the sargassum fusiforme. The invention further provides the sargassum fusiforme which is obtained through the sargassum fusiforme arsenic removal process. Compared with the prior art, the sargassum fusiforme arsenic removal process utilizes the ultrasonic processing to carry out arsenic removal, pollutant cannot be led in during the arsenic removal process, new pollutant also is not produced, and the sargassum fusiforme arsenic removal process is simple and easy to achieve, convenient to operate, and wide in application prospect. According to the arsenic removal process, while the arsenic content is effectively reduced, original flavor of the sargassum fusiforme cannot be changed, original nutrient content of the sargassum fusiforme is remained, the arsenic content of the sargassum fusiforme obtained through the sargassum fusiforme arsenic removal process is remarkably reduced, and security assurance is provided for safe eating of the sargassum fusiforme and development of relative products.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a process for removing arsenic from hijiki. Background technique [0002] Sargassum belongs to Phaeophyta, Yuanzigang, Fucusaceae, Sargassumaceae, and Sargassum genus. The algal body is yellow-brown, plump and juicy, 15-40 cm high, up to more than 2 meters. The fronds are highly variable and have many shapes. It grows on rocks in the low tide zone, and is mostly distributed along the coast of my country, from the Liaodong Peninsula in the north to the Leizhou Peninsula in the south, and most of them are in the coast of Zhejiang. Hijiki is recognized as the most edible marine algae today, and it is an ideal natural product for infants and the elderly. Japan calls it "longevity dish", and it is imported from my country in large quantities every year. [0003] Studies have found that hijiki contains 18 important amino acids needed by the human body (including...
