Seven Major Acid Series Products

Digestive acid, intestinal acid, preservative acid, environmental control acid, liquid acid, antiviral acid, antioxidant acid

Through research into the functions and applications of various acids, we have classified them into seven major acid families: environmental control acids, drinking water acids, preservation acids, digestive acids, intestinal acids, antiviral acids, and antioxidant acids. Based on the physicochemical properties and functions of individual acids, and through rational formulation combined with appropriate processing techniques, we have developed a series of products and solutions that address specific challenges in industrial production.

Environmental Control Acid

Environmental acid refers to a composite acidifier that leverages the antibacterial properties of acids and, through specialized processing, significantly reduces their corrosiveness for use in environmental spray disinfection. Common single acids include formic acid, propionic acid, ammonium formate, and ammonium propionate.

Liquid Acid

Liquid acids primarily leverage the physicochemical and antibacterial properties of acids to purify water and clear pipelines, while also aiding digestion without affecting water intake. These composite acids added to water lines are referred to as drinking water acids. Drinking water acids typically use single acids and their salts—characterized by strong antibacterial and bactericidal activity and good water solubility—as primary ingredients, supplemented with carboxylic acid complexes. These include formic acid, ammonium formate, acetic acid, ammonium acetate, propionic acid, ammonium propionate, butyric acid, sodium butyrate, lactic acid, and citric acid. To more effectively lower the pH of the water line, a small amount of phosphoric acid may be added.

Antiviral Acid

Antiviral acids are a novel class of acid-based formulations that, based on the mechanisms of viral infection, selectively target multiple acid molecules to disrupt viral envelope structures and competitively bind to their active targets. This reduces viral attachment activity and interferes with viral genome replication and protein synthesis, ultimately diminishing viral infection and proliferation in feed and within the host. Commonly used acid molecules include caprylic acid, capric acid, lauric acid, and their monoglycerides.

Antioxidant Acid

Antioxidant acids are in vivo antioxidants developed using OAE® Optimal Acid Effect technology and AEI® Acid Electron Interference technology, based on Lewis acid–base electronic theory. On one hand, they activate the Nrf2‑regulated intracellular antioxidant signaling network, modulating the expression of endogenous antioxidant enzymes such as SOD, CAT, and GSH‑Px to enhance cellular antioxidant capacity. On the other hand, they can selectively quench and scavenge free radicals, reducing their damaging effects on cells, thereby ultimately alleviating oxidative stress in the body and decreasing oxidative injury.

Antioxidant acids are in vivo antioxidants developed using OAE acid‑efficiency optimization technology and AEI acid‑electron interference technology, based on Lewis acid–base electronic theory. On one hand, they activate the Nrf2‑regulated intracellular antioxidant signaling network, modulating the expression of endogenous antioxidant enzymes such as SOD, CAT, and GSH‑Px to enhance cellular antioxidant capacity. On the other hand, they can selectively quench and scavenge free radicals, reducing their damage to cells, thereby alleviating systemic oxidative stress and decreasing oxidative injury.

Qi Mei Su 1001

A composite antioxidant that integrates multiple antioxidant ingredients and is formulated using an innovative process; backed by numerous successful applications, it effectively prevents oxidation and spoilage of various feed ingredients, enhances the quality and stability of animal feed, and promotes animal health and food safety.

Qi Mei Su

Qimei Su is a green, highly effective in vivo antioxidant developed based on the Lewis acid–base electronic theory, utilizing OAE’s optimized acid‑enhancement technology and AEI acid‑electronic interference technology. First, it efficiently activates the body’s endogenous antioxidant signaling system, inducing the production of superoxide dismutase, catalase, and glutathione peroxidase to mitigate oxidative damage caused by various stressors. Second, it directly scavenges free radicals, reducing cellular harm and improving the quality of meat, eggs, and milk. Third, it reduces mucosal and intestinal epithelial inflammation, preventing the accumulation of large amounts of inflammatory cytokines triggered by long-distance transport, heat stress, and other factors.
