Reb M (Rebaudioside M) is a sweetener extracted from stevia or produced through enzymatic conversion. It is a white crystalline powder at room temperature and pressure and can be used in food and beverage products.

Thiamphenicol is a broad‑spectrum antibiotic active ingredient with potent inhibitory effects against both Gram‑negative and Gram‑positive bacteria. It is widely used in the prevention and treatment of respiratory and digestive tract infections in livestock and poultry, as well as bacterial diseases in aqu...

Zeaxanthin is an isomer of lutein and is the most common carotenoid alcohol found in nature. It is the source of color in chili, corn, saffron, and many other plants.

β-Carotene belongs to the carotenoid family. It is a ubiquitous and most stable natural pigment, an orange-yellow, fat-soluble compound that appears as a lustrous, orthorhombic hexahedral or crystalline powder. It is primarily derived from green plants and yellow or orange-yellow fruits and other natural f...
