English Name: Trimethylamine oxide, dihydrate

Abbreviation: TMAO

CAS Number: 62637-93-8

Molecular Formula: C₃H₁₃NO₃

Molecular Weight: 111.14

Physical and Chemical Properties

Appearance: Off-white crystalline powder

Melting Point: 93-95°C

Natural Occurrence

Trimethylamine oxide is widely present in nature, serving as an endogenous substance naturally occurring in aquatic products and a characteristic compound that distinguishes aquatic products from other animals.

Unlike DMPT, which is primarily found in seafood, TMAO is present not only in marine products but also in freshwater fish. The TMAO content in the muscle of marine fish is higher than that in freshwater fish.

Product Applications

As a natural and safe feed additive, trimethylamine oxide holds broad development prospects in the livestock industry.

Main functions include:

1. Promoting muscle tissue growth by stimulating muscle cell proliferation

2. Increasing bile volume and reducing fat deposition

3. Participating in osmotic pressure regulation in aquatic animals

4. Stabilizing protein structures

5. Improving feed conversion rate

6. Increasing lean meat percentage (by reducing carcass fat content)

7. Providing a unique umami and refreshing sweetness that enhances feed palatability

Usage Dosage:

For shrimp, marine fish, eel, and soft-shelled turtle: Add 1-2kg/ton of complete compound feed

For freshwater shrimp and freshwater fish: 1-1.5kg/ton of complete compound feed
