Embodiment 1

[0014] Collect mature sage algae and Ulva, and perform preliminary cleaning in seawater to remove impurities and sediment in the algae; clean the sage algae, Ulva and crab shell powder according to the percentage of components Premixing, and then crushing with crushing equipment, wherein 700g of sargassum, 200g of Ulva, 5g of crab shell, and 5g of water were added for crushing, and a mixture of granules and algae liquid was made.

Embodiment 2

[0016] Take 650g of sargassum, 300g of Ulva, and 5g of crab shell powder and pulverize them with a pulverizer to make a mixture of granules and algae liquid, which is the fresh sargassum.

[0017] The mixed liquid prepared in the above examples is placed at a lower temperature for quantitative packaging. It is advisable to mix 4 kg of mixed fresh material with 1 kg of sand-filtered, boiled and cooled seawater for each portion to form a quantitative mixed liquid with a total weight of 5 kg. The mixed solution is packaged in PE packaging bags.

[0018] The packaged sargassum mixed fresh material is subjected to low-temperature treatment within 2 hours at a temperature of -12 to -20°C, and quickly forms a block product that is easy to maintain the fresh ingredients of sargassum and is easy to transport. The product can be used at 0 Store in a refrigerator below ℃.

Abstract

The invention relates to fresh sargassum thunbergii. The fresh sargassum thunbergii comprises the following components by mass percent: 55-70% of sargassum thunbergii, 25-35% of ulva lactuca and 5-10% of crab shell powder. A preparation and preservation method comprises the following steps: mixing the sargassum thunbergii, the ulva lactuca and the crab shell, and crushing the mixture into a mixed solution of granules and algae liquid; and diluting the fresh sargassum thunbergii with sterilized seawater, and preserving the fresh sargassum thunbergii in a sealed way. The prepared frozen product of the fresh sargassum thunbergii can keep nutrients of the fresh sargassum thunbergii before freezing and has the characteristics of balanced and all-around nutrition of the sargassum thunbergii; the ulva lactuca is introduced into the fresh sargassum thunbergii to partially substitute the sargassum thunbergii, so that the raw material source is very wide, the ulva lactuca is comprehensively utilized and advantages of environment friendliness and safety are sufficiently embodied; the added crab shell powder can effectively maintain a buffer system of the fresh sargassum thunbergii liquid and prevent degradation of the sargassum thunbergii; the preparation and preservation method is simple and feasible and can be implemented by only simple crushing equipment, simple freezing equipment and a low-temperature preservation refrigeratory; requirements on auxiliary facilities are not high; and the preparation and preservation method is easy to operate and implement.

Description

technical field [0001] The invention belongs to the technical field of sargassum processing and utilization, and in particular relates to a sargassum fresh material and a preparation and preservation method thereof. Background technique [0002] Sargassum thunbergii is a large-scale economic seaweed belonging to Phaeophyta, Enculiae, Fucusaceae, Sargassumaceae, and Sargassum genus. It is a common wild species in the coastal areas of my country. Peninsula, south to Leizhou Peninsula are distributed. With the deepening of its research in recent years, some important functions of Sargassum have been gradually discovered: in addition to occupying an important position in the marine ecosystem, it also has many potentials that can be developed in industries such as medicine, health care, and chemical industry. And its bait as a famous and excellent species of aquaculture has been widely used in the aquaculture industry. [0003] At present, scholars from all over the coast of my ...
