L-tyrosine is an odorless, extremely bitter white powder that is soluble in dilute acids and alkalis, but insoluble in anhydrous ethanol, ether, and acetone. L-tyrosine is widely used, not only in food, feed, medicine, health care products, daily chemicals, and other fields that can be used as a nutritional fortification and moisturizing agent but also in the field of biochemical research.
L-tyrosine can be obtained from a variety of raw materials, such as casein, casein, silk, pig’s blood meal, silk, horn shoe, etc., which can be used as raw materials for the preparation of L-tyrosine. How do you use casein to get L-tyrosine? Using casein as raw material, put it into hydrochloric acid for reflux for several hours, and then through filtration, concentration, alkali neutralization, activated carbon treatment, crystallization, and other treatments to obtain L-tyrosine. How do you make L-tyrosine using casein or silk? Casein or silk protein as raw materials, hydrolysis, neutralization reaction, precipitation separation, dissolved in dilute ammonia water, with acetic acid neutralization, adjust the pH value to 5, recrystallization to obtain L-tyrosine. In addition, L- tyrosine can be obtained from pig blood meal, horn shoe, and silk by proteolytic extraction.
