Special preservative for enzymatic solution: Lock in nutrients from the very beginning, ending spoilage and waste.
Enzyme solutions (such as fish protein water-soluble fertilizer, plant-derived enzymatic solutions, peptone solutions, etc.) are rich in organic nutrients such as amino acids, peptides, and active proteins, and are the core raw materials in modern agriculture and the field of biological fermentation. However, the high organic matter and high moisture content of enzyme solutions naturally make them ideal breeding grounds for bacteria, molds, and yeast. After production and filling, residual bacteria continuously decompose nutrients, metabolize and produce irritating odors such as hydrogen sulfide and ammonia, resulting in problems such as swollen barrels, turbid liquid stratification, and blackening at the bottom of the container, causing a large amount of finished products to be scrapped and resulting in excessive returns and losses. Dalian Tianwei has developed a dedicated composite preservative based on the characteristics of the enzyme solution system, with the core of targeted compound slow-release technology, to achieve full-cycle microbial protection from the production end.
01 Why does the enzymatic solution require a special preservative?
The enzymatic solution is made from natural animal and plant raw materials (such as deep-sea fish, soybean meal, peptone, etc.) through enzymatic processing. It contains a large amount of free amino acids, small molecule peptides, sugars, and other active substances, providing an ideal environment for microbial proliferation. The microbial risks faced by the enzymatic solution are present throughout the entire production chain:
Production process risks: During the enzymatic process, the temperature and humidity are suitable. If the equipment and pipelines are not thoroughly cleaned, pathogenic bacteria (such as Escherichia coli, Bacillus, Aspergillus niger, etc.) can rapidly multiply, causing the enzymatic solution to deteriorate.
Storage and transportation challenges: After the finished product is filled, it undergoes long-distance transportation, storage in high-temperature warehouses, and changes in temperature differences between the north and south. Residual bacteria continuously decompose nutrients, directly resulting in problems such as gas expansion, bulging, liquid stratification, and precipitation in appearance.
Usage end risks: The deteriorated enzymatic solution not only loses its original active nutrients but is also prone to the proliferation of harmful bacteria - when used for agricultural fertilization, it will cause root diseases in the soil; when used for biological fermentation, it will contaminate the subsequent cultivation system.
Conventional general-purpose preservatives have poor compatibility with the protein colloid system of the enzymatic solution and can only inhibit bacteria for a short period of time. They cannot fully cover the protection throughout the entire storage and transportation cycle and are prone to react with amino acids and peptides, destroying the activity of the effective components. Therefore, to stabilize the quality of the enzymatic solution from the production end, a special preservative is a necessary supporting additive.
02 Core Product Advantages of Dalian Tianwei Chemical
Dalian Tianwei has been deeply engaged in the field of organic liquid microbial control. It has developed a dedicated composite anti-corrosion formula specifically for the special system of enzymatic liquid protein colloid, which is different from general-purpose anti-corrosion raw materials. The three-layer action mechanism works simultaneously, with the core being the collaborative slow-release compound technology, to build a full-cycle microbial protection.
Targeted compounding, three-layer antibacterial mechanism
Quick sterilization: Penetrates the microbial cell membrane, destroys the osmotic pressure of the bacteria, instantly inactivates pathogenic bacteria such as Escherichia coli, Bacillus subtilis, and Aspergillus niger in the enzymatic solution, with a comprehensive antibacterial rate of 99.9% and a mold prevention level of 0 grade.
Long-term retention: Inhibits the microbial enzyme metabolic system, prevents the breakdown and consumption of proteins and amino acids, firmly locks in the original nutrients of the fertilizer, avoiding significant loss of fertilizer efficacy.
Odor degradation: Degradation of system-generated sulfur compounds, ammonia, etc. from the decomposition of spoilage metabolism, solving the problem of odor and bulging barrels from the root cause, maintaining the liquid's uniform and transparent state.
Wide pH compatibility, compatible with all processes
Applicable pH range is 3-10. Various enzymatic solution formulas including acidic, neutral, and weakly alkaline can be added. The liquid additive is convenient for feeding, directly mixed without secondary emulsification. The addition amount is only 0.1%-0.4%, a small amount can meet the anti-corrosion standard, suitable for automated filling lines, without the need to modify equipment processes.
Temperature stability, long-term protection
The active components are encapsulated in microcapsules, maintaining stable performance in an 80℃ high-temperature filling environment. It is not prone to failure even in summer high-temperature storage or long-distance transportation. Experimental data shows that it can still effectively inhibit microbial proliferation in high-humidity and high-temperature environments, significantly extending the shelf life of the finished product.
Green and environmentally friendly, with no residual risks
Does not contain formaldehyde, heavy metals, or strong irritating solvents. Zero solvent and zero VOCs. Low migration and low residue. When used for agricultural fertilization, leaf spraying and root irrigation have no risk of crop damage. It complies with the green production standards of ecological organic fertilizers; when used in the field of biological fermentation, it will not pollute the subsequent cultivation system.
Dual functions of preservation and remediation
For semi-finished products with slight bacterial contamination and slight acidity during production, the additive can quickly inhibit the spread of miscellaneous bacteria, decompose odor-causing metabolic substances, restore the properties of the enzymatic solution, and reduce the loss of raw materials. It can also be used simultaneously for daily disinfection and sterilization of production tanks and transportation pipelines, achieving microbial protection throughout the entire chain of raw material storage, finished product filling, and pipeline disinfection.
