Frequently Asked Questions
It acts as a vital sulfur source for methionine, promoting the formation of the calcification matrix. Experimental data shows an increase in eggshell thickness by 10-12μm and a reduction in breakage rate by 18%.
Yes. The -SH groups in the molecule directly bind to Aflatoxin B1 (AFB1) epoxides, which has been shown to reduce liver residues by up to 55% based on HPLC-MS validation.
To maintain stability, avoid direct mixing with strong oxidizers, such as Copper Sulfate (CuSO₄). We recommend utilizing premix homogeneity with a CV ≤ 5%.
It reduces disulfide bonds in gluten via its sulfhydryl groups, enhancing dough elasticity and increasing the specific volume of bread by 12-18% compared to GB/T 20981 standards.
It inhibits tyrosinase activity with an IC50 of 2.3mM (more potent than arbutin's 4.1mM), effectively reducing melanin production while remaining compliant with safety regulations.
Absolutely. It is used in fish and shrimp feed to regulate molting cycles and reduce hepatic malondialdehyde (MDA) by 35%, lowering oxidative stress in high-density farming.
