About Tert-Butylhydroquinone E319-1948-33-0
poor heat resistance, not in frying, baking under the conditions of use, E319 with butylated hydroxyanisole to improve with use. E319 for the storage of vegetable oil at room temperature is better. Another E319 still has some antibacterial effect, especially in the slightly acidic salt-mediated combined with better. E319 on other antioxidants and chelating agents have synergies, adding citric acid can enhance its antioxidant activity. In vegetable oil, bulk oil and animal oil, E319 is generally used in combination with citric acid. Reactive oxygen species was determined using the oxidation stability of lard when, E319 role equal to butylated hydroxyanisole, more than butylated hydroxytoluene and propyl gallate. The E319 incorporation into packaging materials can effectively inhibit the oxidative deterioration of lard. Poultry fat, E319 Biding Ji hydroxyanisole, butylated hydroxytoluene or propyl gallate more effective.
