Problems solved by technology

[0004] At present, there is no technical report that can directly improve the solubility of salina dry powder. If the β-carotene in salina is not extracted or enzymatically treated, it is difficult to realize the utilization of β-carotene in salina
However, if the salina is extracted from β-carotene or enzymatically hydrolyzed, other active ingredients will be wasted

preparation example Construction

[0035] The invention provides a preparation method of salina solid functional drink, comprising the following steps:

[0036] (1) mixing the beverage additive, salina dry powder and microcrystalline cellulose to obtain a mixture;

[0037] (2) mixing the mixture with water, and performing high-pressure homogenization treatment to obtain a mixed solution;

[0038] (3) Spray-drying the mixed solution to obtain the salina solid functional drink.

[0039] The invention mixes the beverage additive, salina dry powder and microcrystalline cellulose to obtain the mixture. In terms of parts by mass, the raw materials for preparation in the present invention preferably include 0.88-2.0 parts of blue-green algae dry powder, more preferably 1.0-2.0 parts. In the present invention, the mass percent content of β-carotene in the salt algae dry powder is preferably 3-10%, more preferably 6%; the particle diameter of the salt algae dry powder is preferably 0.01-0.10mm; the Salina dry powder ...

Embodiment 1

[0051] Weigh 20g of salina dry powder, add it to 500ml of distilled water, and treat it with a normal pressure homogenizer (1 standard atmosphere, 101Kpa) and a high pressure homogenizer (40000KPa) for 10 minutes respectively, and compare the dispersion effects of the two.

[0052] Test results such as figure 1 and figure 2 as shown, figure 1 It is the dispersion effect after 10 minutes of normal pressure homogenization. It can be seen that after normal pressure homogenization and standing for about 10 minutes, there is obvious precipitation at the bottom of the beaker, and there are lumps floating on the surface; figure 2 For the dispersion effect after high-pressure homogenization for 60 minutes, it can be seen that the solution is uniform and moderate in color after high-pressure homogenization, and there is no layered precipitation after standing for more than 60 minutes, and it can pass through the cellulose acetate filter membrane with a pore size of 0.45 microns. It...

Embodiment 2

[0054] (1) Weigh 25g of salina dry powder with a percentage content of β-carotene of 5% in treatment 1 and treatment 2, add them to 1L distilled water respectively, prepare treatment 1 and treatment 2 respectively as follows, and take another 25g of salt Algal dry powder was used as blank control;

[0055] Treatment 1 (T-1): The mixture of salina dry powder and water is subjected to high-pressure homogenization for 10 minutes at a temperature of 80°C and a pressure of 400 bar, and then vacuum freeze-drying at a vacuum degree of 100 Pa;

[0056] Treatment 2 (T-2): The mixture of salina dry powder and water is homogenized under high pressure for 10 minutes at a temperature of 80°C and a pressure of 400 bar, and then spray-dried;

[0057] Blank control treatment (Control): Salina dry powder was not treated in any way.

[0058] (2) Add three treated dry algae powders to 200 mL of 40°C distilled water respectively. The dissolved system was stirred at 60 r / min with a constant spee...

Abstract

The invention belongs to the technical field of functional beverage, and particularly relates to a dunaliella salina solid functional beverage and a preparation method thereof. The preparation methodfor the dunaliella salina solid functional beverage comprises the following steps of: (1) mixing beverage additives, dunaliella salina dry powders and microcrystalline celluloses to obtain a mixture;(2) mixing the mixture and water, and carrying out high-pressure homogenizing processing to obtain a mixed liquid; and (3) carrying out spray drying on the mixed liquid to obtain the dunaliella salinasolid functional beverage. An embodiment result indicates that the dunaliella salina solid functional beverage provided by the invention improves the solubleness of [beta]-carotene, a taste is improved, and the dunaliella salina solid functional beverage has a slightly sweet taste, is smooth, is free from a fishy smell and fully utilizes effective ingredients in dunaliella salina.

Description

technical field [0001] The invention belongs to the technical field of functional drinks, and in particular relates to a salina solid functional drink and a preparation method thereof. Background technique [0002] Salina is a highly salt-tolerant unicellular green algae, rich in glycerol, and the natural β-carotene in the cells can reach more than 5%, which has extremely high economic value. The functions of natural β-carotene to improve vision and scavenge free radicals have been proved by a large number of studies and are widely recognized. In 2009, salina was identified as a new resource food, which means that salina does not cause any acute, subacute, chronic or other potential health hazards to the human body. [0003] However, due to the strong algae smell of salina and the fact that β-carotene can only be dissolved in organic solvents such as ethanol and dimethyl sulfoxide, the application of salina as the main raw material of beverages is greatly limited. The trad...
