Abstract
Potassium sorbate, nisin and Heptyl 4-hydroxybenzoate were used as complex preservatives for prolonging the preservation time of draft beer. Their best adding levels were determined as follows:0.25 g/L potassium sorbate, 0.35 g/L Nisin and 0.10 g/L Heptyl 4-hydroxybenzoate. The experimental results suggested that such method could prolong the preservation time of draft beer at least 4 d.
