Problems solved by technology

[0007] Although seawater chlorella is rich in nutrients, its nutrients will be lost in a large amount during the process of making algae powder and algae flakes, and its vitality will be lost, and it will no longer have the function of regulating and purifying water quality.
Moreover, some substances harmful to the body may be added in the production process
[0008] Live seawater chlorella is prone to aging and apoptosis during storage, and is easily polluted by bacteria, resulting in foul smelling precipitation, which is not easy to store for a long time
It needs to be frozen for storage, but once it is frozen, it will cause a great loss of vitality and increase the cost of storage
Because it is difficult to preserve at room temperature, there are relatively few studies on its preservation at room temperature

Embodiment 1

[0027] Embodiment 1 Microalgae preservation composition of the present invention

[0028] Table 1 Microalgae preservation composition of the present invention (Material A)

[0029] serial number Material name weight 01 Lysozyme 0.06g 02 Cinnamon Essential Oil 2.5mg 03 Paretin 0.32g

Embodiment 2

[0030] Embodiment 2 Microalgae preservative of the present invention

[0031] Consist of the fresh-keeping composition (A material) and auxiliary agent (B material) of embodiment 1:

[0032] Table 2 Composition of additives (material B)

[0033]

[0034]

[0035] Configuration method:

[0036] 1. Take two high-temperature-resistant plastic containers (or glass containers), and metal containers are prohibited. After disinfection (if it can be sterilized, it is better) for use;

[0037] 2. Add 3-4L of sterile water (boiled water can also be used to speed up the dissolution rate) in each high-temperature-resistant plastic container, slowly pour material A and material B into the two containers, and stir well until the mixture is uniform (a small amount of precipitation belongs to Normal), when the mixed solution in a single container is less than 5L, add enough sterile water to 5L;

[0038] 3. After the water temperature in the two containers is cooled, pour the liquids ...

Embodiment 3

[0039] Embodiment 3 Fresh chlorella algae are stored at room temperature

[0040] preservation method:

[0041] 1. Filter the cultured seawater chlorella with a 50-micron filter membrane to remove large particles.

[0042] 2. Shake the microalgae preservative evenly before subpackaging the seawater chlorella algae liquid, pour it evenly into the algae liquid, and stir evenly. It is normal to have a small amount of sediment in the bottle after the algae liquid is dispensed;

[0043] 3, embodiment 2 prepares microalgae antistaling agent (when 10L), its addition accounts for 1.6-3.2% (w / w) of algae liquid,

[0044]4. After the algae solution added with the microalgae antistaling agent of the present invention is bottled, it is placed in a carton to maintain a dull state and stored at room temperature.

[0045] Add 2% (w / w) microalgae antistaling agent of embodiment 2 in every liter of seawater chlorella (algae body density 500-2000 / ml) that is freshly harvested, and place it in...

Abstract

The invention relates to the technical field of microalgae, in particular to a microalgae fresh-keeping agent and a microalgae preservation method. The microalgae fresh-keeping composition comprises lysozyme, cinnamon essential oil and celastrus angulatus, and at least one auxiliary agent of sodium benzoate, sodium dehydroacetate, sodium carboxymethyl cellulose and gentamicin sulfate is further added into the composition to obtain the microalgae fresh-keeping agent. Experiments show that the microalgae fresh-keeping agent disclosed by the invention is used for preserving microalgae liquid or microalgae mud at normal temperature, the preservation time is long, the activity of microalgae is high and the content of infectious microbes is low as long as 6 months or above.

Description

technical field [0001] The invention relates to the technical field of microalgae, in particular to a microalgae fresh-keeping composition, a fresh-keeping agent and a preservation method thereof. Background technique [0002] The main function of food preservation is to extend the storage period of food, maintain the original flavor of food and reduce energy consumption. Food preservation is based on its quality characteristics and spoilage mechanism, using physical, chemical and biological methods in its production and distribution process to inhibit or delay the spoilage of fresh food and maintain its good freshness and quality. Traditional food storage methods include heat treatment, low temperature, drying, sugar marsh, salt marsh, smoking, etc. Although these methods can prolong the shelf life of food, they all have shortcomings. For example, the method of freezing will cause high energy consumption; heating, The methods of drying and dipping are easy to destroy the o...
