It was initially identified as a gelling agent to replace agar at significantly lower concentrations in solid culture media for the growth of various microorganisms. [2] Its initial commercial product with the trademark as Gelrite gellan gum, was subsequently identified as a suitable agar substitute as gelling agent in various clinical ...
Peanut oil/Ground nut oil – mild-flavored cooking oil. Pecan oil – valued as a food oil, but requiring fresh pecans for good quality oil.
