Eucasin is spelled as [juːˈkeɪsɪn] in IPA phonetic transcription. The word is pronounced as "yoo-kay-sin." The spelling of the word follows the English language pattern, where the letter "e" is silent before "u." Eucasin is a dairy product that serves as a substitute for casein. It is obtained by the enzymatic modification of lactose, which results in a decrease in casein content. Eucasin is commonly used in the food industry as a stabilizer, emulsifier, and thickener.
