First, culture conditions The most important conditions for breeding Spirulina are light, temperature, culture fluids and ventilation. The pH, depth, flow, oxygen, and reasonable supply of nutrient elements are all important factors affecting production. Therefore, the culture tank should be built in a place where the water quality is good, the light conditions are suitable, and the site is wide. The pH value range is 7-11, preferably 8-9; the water depth is 0.2-0.3 m; the water temperature is 18-38°C, the most Fortunately, 26 to 32°C.
Second, aquaculture varieties The current domestic and international production of major cultured species is Spirulina platensis (original Africa Lake Chad) and Spirulina (original production of Mexico). China's algaeologists discovered a natural variant strain of spirulina suitable for temperate growth along the coast of Huangpi County in Hebei Province. The strain was identified as Spirulina platensis strain 6 (S6). Spirulina platensis strain 1 (S1) was introduced from Chad in China. China also cultivated Spirulina ST-6 strain and Spirulina salt. These varieties (strains) can be selected according to local conditions. Among them, Spirulina sinensis is an alga species that adapts to the reproduction of high temperature, salt water and seawater.
Third, culture methods
1. Family farming: You can purchase spirulina family culture instrument, you can also choose enamel basin (preferably white) or cylinder bowl, but the aluminum bowl can not be used. The scale of cultivation should be based on the amount of spirulina used annually. If a basin with a diameter of 36 cm is used, 12 children need 1 child, while 1 adult needs about 20 people.
2. Easy breeding: mainly refers to the simple equipment, the breeding pool can be drawn on the spot, as long as it does not leak water on the line. The depth of the pool is 30 cm. The area should be as large as possible. It can be calculated as 1.5 meters per adult.
3. Natural lake breeding: Spirulina is originally a primitive algae that naturally grows in salt lakes. The use of natural lake breeding is the most primitive and economical production method. Its equipment requirements are very low. It is only necessary to invest in snoring and processing. The fertility of the lake can be restored naturally. However, due to spirulina's special requirements for light, temperature, pH, etc., not all lakes can be cultured, but should be selected through experiments, studies, and selection of lakes suitable for reproduction.
4. Factory farming: advanced equipment, large scale and strict requirements. At present, the aquaculture pond is better equipped with a racetrack oval cement pool, and the breeding area is preferably 15,000 m2 as a unit. Open cultures can also be used, but also closed production. Open cultivation is a near-natural production method. It is divided into freshwater and seawater. Most of the culture pools are designed to be recyclable. They are stirred by a mixer and the depth of the culture fluid is 15 to 25 cm. Daylight is used as a light source and heat source. Closed production refers to a method of production of Spirulina planted in a closed bioreactor using natural light or artificial light.
Fourth, the breeding process Spirulina nutrient elements in addition to nitrogen, phosphorus, potassium, the largest demand is the carbon source (CO2). Its main nutrient formula is baking soda, salt, potassium sulfate, magnesium sulfate, sodium nitrate, calcium chloride, and iron sulfite. The production process is as follows: Algae cultivation pool (original species)→first-level culture→secondary culture→production pond→harvest→rinse→dehydration→spray drying→sterilization→inspection→packaging→storage→pharmaceutical grade and food grade (or dehydration → natural drying → feed grade).
V. Enemy Prevention and Control Spirulina species have many types of contaminating organisms. The species that are most at risk are rapidly multiplying in the algal fluid. For example, large rotifers can directly devour algal cells, and the metabolites produced by enemy organisms secrete Algal cells have a great toxic effect. Predator-prey organisms should be given priority to prevention, and pollution should be strictly prevented. Algae's growth advantages and quantitative advantages should be maintained. Algae's growth should be maintained, and algae species should be separated, preserved, and supplied; at the same time, they must be promptly completed. Prevention work can be used to remove large enemy predators by filtration methods. Drugs can be used to suppress or kill predator organisms, and environmental conditions can also be used to suppress or kill predators.

Sweeteners are food Additives that give soft drinks sweet taste. Sweeteners can be divided into nutritive sweeteners and non-nutritive sweeteners according to their nutritional value, low sweetness sweeteners and high sweetness sweeteners according to their sweetness, and natural sweeteners and synthetic sweeteners according to their sources. The sweeteners produced and sold by our company have the characteristics of high safety, good taste, high stability, good water solubility and reasonable price.
The main function of sweeteners
The main role of sweeteners in food:
(1) Palate: Sweetness is one of the indicators of many foods, in order to make food and beverage have a palatable feeling, it is necessary to add a certain amount of sweetener.
(2) The regulation and enhancement of flavor, generally need sweet in pastries; in beverages, the adjustment of flavor has a "sugar-acid ratio" item. Sweeteners can make the product get good flavor and retain fresh taste.
(3) The formation of flavor, sweetness and the flavor of many foods are complementary, many products taste is produced by the combination of flavor substances and sweeteners, so many foods are added sweeteners.
There are many kinds of sweeteners, which can be divided into natural sweeteners and synthetic sweeteners according to their sources, nutritive sweeteners and non-nutritive sweeteners according to their nutritional value, and sugar and non-sugar sweeteners according to their chemical structure and properties.
Glucose, fructose, sucrose, maltose, starch sugar and lactose are natural sweeteners, but because they have long been eaten by people and are important nutrients, they are usually regarded as food raw materials and are not used as food additives in China.
Non sugar sweeteners are natural sweeteners and synthetic sweeteners. Natural sweeteners include stevia, licorice, Disodium Glycyrrhetate, three potassium glycyrrhizinate and three sodium. Synthetic sweeteners include saccharin, saccharin sodium, sodium cyclohexylaminosulfonate, aspartate phenylalanine methyl ester alitame, etc.
