Description

Technical Field

[0001] The invention relates to the technical field of seaweed fermented feed, in particular to green feed fermented by using seaweed as auxiliary material and a preparation method thereof. Background Art

[0002] Seaweed fermented feed is a green feed that uses seaweed as the main raw material and is prepared through bio-fermentation technology. Seaweed fermented feed is nutritious and environmentally friendly. It can improve the immunity of farmed animals, inhibit the growth of pathogens, reduce diseases, and promote growth.

[0003] Disadvantages of not using seaweed fermented feed 1. Unable to effectively inhibit the growth of pathogens Fermented seaweed feed can produce a variety of organic acids, lower the pH value, and destroy the growth environment of harmful bacteria. If you don't use it, you won't be able to enjoy this antibacterial effect; 2. Reduced digestibility and utilization of nutrients The fermentation process can degrade macromolecular organic matter and produce rich microbial protein. If fermented feed is not used, the animal's absorption efficiency of these nutrients may be reduced; 3. Accumulation of toxic substances and anti-nutritional factors Fermented feed can degrade toxic substances and anti-nutritional factors in feed. If not used, these harmful substances may accumulate in the animal's body and affect health; 4. Weakened digestive function and immunity Long-term and appropriate addition of fermented feed can improve animal digestion function, enhance nutrient absorption and immunity. Failure to use it may lead to digestive disorders and decreased immunity in animals. Summary of the invention

[0004] The purpose of the present invention is to provide a green feed using seaweed as an auxiliary material for biological fermentation and a preparation method, so as to effectively avoid the problems of existing feeds that cannot effectively inhibit the growth of pathogens, reduced digestibility and utilization of nutrients, accumulation of toxic substances and anti-nutritional factors, and weakened digestive function and immunity.

[0005] To achieve the above object, the present invention provides the following technical solutions: The green feed and preparation method using seaweed as auxiliary material for biological fermentation include the following steps: S1: Preparation of materials: kelp, red algae, brown algae, EM compound bacterial agent, trace element molasses complex, vegetable powder, pure culture of Lactobacillus bulgaricus and Streptococcus thermophilus‌‌.

[0006] S2: Classify and process various materials: 1. Kelp, red algae and brown algae: clean the algae and remove sand and other impurities on the algae; 2. Activation and expansion of EM compound bacterial agents: Activate the EM compound bacterial agents and expand the culture to ensure their activity; 3. Anaerobic and aerobic combined fermentation of seaweed powder: The seaweed powder is fermented anaerobicly and aerobically to destroy its colloid and improve the absorption rate of nutrients; 4. Preparation of trace element molasses complex: complex the trace elements with molasses to form a complex that is easy for animals to absorb; S3: Fermentation process of seaweed: 1. Prepare the fermentation broth: Add pure cultures of Lactobacillus bulgaricus and Streptococcus thermophilus into a fermentation container and add water to make a fermentation broth; 2. Seal the seaweed: Place the drained seaweed into the fermentation container and seal it with a lid; 3. Fermentation: Move the fermentation container into the fermentation room and take out the seaweed when the pH value of the fermentation liquid reaches 3-5; S4: Mixing and drying: The fermented seaweed is dried and ground into powder, mixed evenly with trace element molasses complex, vegetable powder and other additives, and then molded and dried and sterilized at high temperature to finally obtain seaweed fermented feed.

[0007] Preferably, in the process of preparing the fermentation liquid in S3, water with a hardness greater than 16 degrees and a temperature of 40° C. to 50° C. needs to be added to the fermentation container to 2 / 3 of the volume of the fermentation container.

[0008] Preferably, during the process of sealing the seaweed in S3, after the seaweed is added to the fermentation container, the fermentation liquid surface needs to be 1 to 2 cm away from the container opening.

[0009] Preferably, the fermentation process in S3 needs to be carried out at 20° C. to 30° C. for 4 to 12 days.

[0010] Preferably, the seaweed taken out after fermentation in S4 can be pressed by plates and frames and then quickly dried at low temperature.

[0011] Preferably, after the seaweed in S3 is fermented once, red yeast, Rhodopseudomonas palustris and sugar residue may be introduced for secondary fermentation.

[0012] Preferably, during the treatment of the seaweed in S2, ammonia water treatment can be used to utilize alkalinity to dissolve part of the lignin, thereby loosening the structure of the seaweed residue and exposing the cellulose.

[0013] In summary, due to the adoption of the above technology, the beneficial effects of the present invention are: 1. Improve immunity: Fermented seaweed feed can improve the intestinal environment of animals and reduce the intestinal pH value by adding beneficial bacteria such as lactic acid bacteria, thereby inhibiting the reproduction of harmful microorganisms and achieving a stable balance of intestinal flora. In addition, the acidic environment can also promote the absorption of trace elements such as iron and calcium, thereby improving the immunity of animals.

[0014] 2. Optimize water quality environment: The beneficial bacteria in fermented feed can accelerate metabolism, increase the animal's food intake and digestion rate, and reduce the emission of bait and toxic and harmful gases in the water. These beneficial bacteria can also degrade organic matter and convert it into inorganic salts that can be absorbed by phytoplankton, thereby purifying the water quality environment.

[0015] 3. Improve feed intake rate: organic acids such as lactic acid produced during the fermentation process increase the sour flavor of the feed and enhance the feed's appetite. At the same time, the beneficial bacteria produced by fermentation are high in protein, which is beneficial to animal digestion and absorption, increases weight, and accelerates its growth rate.

[0016] 4. Green and environmentally friendly: Fermented feed has little pollution to aquaculture and achieves a green and environmentally friendly effect. The beneficial bacteria produced during the fermentation process can degrade organic matter and reduce pollution to the environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention provides Figure 1 The green feed and preparation method using seaweed as auxiliary material for biological fermentation include the following steps: Example 1

[0022] S1: Material preparation: kelp, red algae, brown algae, EM compound bacterial agent, trace element molasses complex, vegetable powder, pure culture of Lactobacillus bulgaricus and Streptococcus thermophilus; S2: Classify and process various materials: 1. Kelp, red algae and brown algae: ‌Washing and soaking‌: First, wash the seaweed in water to remove impurities and sand and gravel on the surface. If the seaweed is recovered from the coast, it may be mixed with a lot of sand and gravel, so the washing process is particularly important‌; ‌ Drying and crushing ‌: The cleaned seaweed needs to be dried and then crushed or smashed into smaller particles. This step helps to increase the surface area of ​​the seaweed, thereby increasing its contact area with the fermentation liquid and improving the fermentation efficiency ‌; ‌Soaking and desalting‌: If the seaweed contains a high salt content, it needs to be soaked in water and then rinsed with clean water to remove excess salt. This step is very important for the subsequent fermentation process, as high salt content may inhibit the growth of fermentation bacteria‌; 2. Activation and expansion of EM compound bacterial agent: Activation process: First, the strain needs to be activated. Usually, appropriate amounts of EM strains, brown sugar, salt, urea and sterile water are mixed in a specific proportion and then fermented in a closed environment at a suitable temperature. When the fermented liquid produces a sweet and sour taste, it means that the activation is successful and can be used as a liquid strain; Expanded culture: The activated strains can be further expanded. Generally, the activated liquid strains are added to the secondary fermentation tank, and water and other nutrients (such as brown sugar, urea, etc.) are added in proportion, and closed fermentation is carried out at an appropriate temperature. During the fermentation process, it is necessary to regularly release gas and reduce pressure. When the fermentation liquid reaches the standard odor, pH value and live bacteria content, it means that the expanded culture is successful. In addition, the activation and expanded culture of the EM compound bacterial agent must pay attention to factors such as temperature, light, and nutritional conditions to ensure the activity and reproduction effect of the strains; 3. Seaweed powder anaerobic and aerobic: Detoxification, disease prevention and immunity enhancement: The chlorella component in seaweed powder has detoxification, anti-inflammatory and antioxidant properties, which can effectively remove heavy metal toxins from the body, prevent chronic diseases, and enhance immunity; Regulate the stomach and control weight: The brown algae extract in seaweed powder can inhibit the absorption of starch and fat, which helps maintain intestinal health and control weight; Moisturizing and anti-aging: Seaweed powder contains rich active ingredients, such as polysaccharides, polyphenols and collagen, which have moisturizing and anti-aging effects; 4. Preparation of trace element molasses complex: complex the trace elements with molasses to form a complex that is easy for animals to absorb; S3: Fermentation process of seaweed: 1. Prepare the fermentation liquid: Add the pure culture of Lactobacillus bulgaricus and Streptococcus thermophilus into the fermentation container, add water, and then add water with a hardness greater than 16 degrees and a temperature of 40℃ to 50℃ into the fermentation container to 2 / 3 of the volume of the fermentation container to make the fermentation liquid; 2. Seal the seaweed: Put the drained seaweed into the fermentation container. After adding the seaweed into the fermentation container, the fermentation liquid surface needs to be 1 to 2 cm away from the container mouth, and then cover it with a lid to seal it; 3. Fermentation: Move the fermentation container into the fermentation room and ferment at 20℃~30℃ for 4~12 days. When the pH value of the fermentation liquid reaches 3-5, take out the seaweed; S4: Mixing and drying: The fermented seaweed is dried and ground into powder, mixed evenly with trace element molasses complex, vegetable powder and other additives, and then dried and sterilized at high temperature after molding to finally obtain seaweed fermented feed.

[0023] Fermented seaweed feed made in the above manner: 1. Improve feed digestibility and absorption rate: Through fermentation, the beneficial bacteria in the feed are enhanced, which improves the digestibility and nutritional value of the feed.

[0024] 2. Enhance immunity: The dominant bacteria formed during the fermentation process helps maintain the balance of microbial communities in water bodies and the intestines of farmed animals, enhances the body's immunity, and reduces the occurrence of diseases.

[0025] 3. Promote growth: Fermented seaweed feed is rich in various trace elements and bioactive substances, which helps animals absorb and utilize trace elements such as vitamin D, copper and iron, thereby promoting the healthy growth of animals. Example 2

[0026] S1: Preparation of materials: kelp, red algae, brown algae and fermentation liquid; S2: Classify and process various materials: 1. Kelp, red algae and brown algae: ‌Washing and soaking‌: First, wash the seaweed in water to remove impurities and sand and gravel on the surface. If the seaweed is recovered from the coast, it may be mixed with a lot of sand and gravel, so the washing process is particularly important‌1. ; ‌ Drying and crushing ‌: The cleaned seaweed needs to be dried and then crushed or smashed into smaller particles. This step helps to increase the surface area of ​​the seaweed, thereby increasing its contact area with the fermentation liquid and improving the fermentation efficiency ‌; ‌Soaking and desalting‌: If the seaweed contains a high salt content, it needs to be soaked in water and then rinsed with clean water to remove excess salt. This step is very important for the subsequent fermentation process, as high salt content may inhibit the growth of fermentation bacteria‌; S3: Fermentation process of seaweed: 1. Prepare the fermentation liquid: Add the pure culture of Lactobacillus bulgaricus and Streptococcus thermophilus into the fermentation container, add water, and then add water with a hardness greater than 16 degrees and a temperature of 40℃ to 50℃ into the fermentation container to 2 / 3 of the volume of the fermentation container to make the fermentation liquid; 2. Seal the seaweed: Put the drained seaweed into the fermentation container. After adding the seaweed into the fermentation container, the fermentation liquid surface needs to be 1 to 2 cm away from the container mouth, and then cover it with a lid to seal it; 3. Fermentation: Move the fermentation container into the fermentation room and ferment at 20℃~30℃ for 4~12 days. When the pH value of the fermentation liquid reaches 3-5, take out the seaweed; S4: Mixing and drying: The fermented seaweed is dried and ground into powder, mixed evenly with trace element molasses complex, vegetable powder and other additives, and then dried and sterilized at high temperature after molding to finally obtain seaweed fermented feed.

[0027] The above methods lack EM compound bacteria, trace element molasses complex, vegetable powder, pure culture of Lactobacillus bulgaricus and Streptococcus thermophilus, and thus have the following defects: 1. Lack of beneficial microbial symbiosis: EM compound microbial agent contains a variety of beneficial microorganisms such as lactic acid bacteria, yeast, photosynthetic bacteria, etc., which form a mutualistic and symbiotic relationship. Without the addition of such microbial agents, this stable microbial symbiotic system cannot be formed; 2. Low efficiency of decomposition of organic matter: EM compound bacteria can effectively decompose organic matter and improve fermentation efficiency. If it is not added, the decomposition rate of organic matter may slow down, affecting the fermentation effect; 3. Limited effect of environmental improvement: EM compound bacteria can inhibit the proliferation of spoilage bacteria and pathogens and improve the environment. Without it, the effect of environmental improvement may be greatly reduced and the activity of harmful microorganisms cannot be effectively inhibited. Fermentation without adding EM compound bacteria will lose its advantages in microbial symbiosis, organic matter decomposition and environmental improvement. 4. Reduced nutritional value: Trace element molasses complex is rich in nutrition and has high biological value. It is an important additive in feed. If this complex is not added for fermentation, the nutritional value of the feed will be reduced, affecting the growth and development of animals; 5. Limited fermentation effect: In the production process of seaweed fermented feed, trace element molasses complex is one of the important raw materials. Its lack may lead to unsatisfactory fermentation effect, affecting the quality of feed and animal digestion and absorption; 6. Affect animal appetite: The complexed and fermented feed usually has a sweet taste, which can improve the appetite of animals. If the trace element molasses complex is not added for fermentation, it may affect the taste and flavor of the feed, thereby reducing the appetite of animals; 7. Slow fermentation rate: Lactobacillus bulgaricus and Streptococcus thermophilus are commonly used strains in yogurt fermentation, and they have a faster fermentation rate. If these two bacteria are not added, the fermentation time may be prolonged, affecting production efficiency; 8. Poor quality; 9. Not conducive to health benefits: Lactobacillus bulgaricus and Streptococcus thermophilus have some specific health benefits, such as improving the ability of lactose in lactose intolerant people to digest lactose. If these two bacteria are not added, these health benefits may be lost.
