Hoat solubility
NettetPolysorbate 80 is used as an emulsifier in foods. For example, in ice cream, polysorbate is added up to 0.5% (v/v) concentration to make the ice cream smoother and easier to handle, as well as increasing its resistance to melting. [6] Adding this substance prevents milk proteins from completely coating the fat droplets. NettetActive esters are less reactive and less in danger of racemization. 1-Hydroxybenzotriazole (HOBt) and 1-hydroxy-7-aza-benzotriazole ( HOAt) are substances that react with the …
