Bir Pletok is a Betawi traditional beverage product made from spices and herbs. Bir Pletok has many advantages, such as to keep body warm and to prevent cold . Bir pletok’s key benefit is related to its antioxidant capacity. The packaging and the storage environment are two important factors in the beverage industry include bir pletok. These factors could affect the antioxidant capacity. The antioxidant capacity in food could decrease due to high temperature and other specific conditions. In the present study the change of antioxidant capacity during the storage and the storage time of bir pletok in the bottle glass packaging with different transperancy and different storage temperature were evaluated. ASS method was used to find the storage time of bir pletok with temperature parameter and ESS method was used to find the storage time of bir pletok with packaging transperancy parameter , whereas the reduction of DPPH method was used to determine the antioxidant capacity of bir pletok during 8 weeks of storage. The storage time of bir pletok that had been storage in 300, 370C, and 500C were 29,45 days, 22,55 days, and 10,67 days respectively. Among the three levels of storage temperatures evaluated in this research, the best temperature for bir pletok storage is 300C. The storage time of bir pletok that had been storage in transparent, brown, and dark bottle glass were 19,28 days, 25,05 days, and 29,91 days respectively. The result of the study showed that the non-transparent packaging was the best condition for bir pletok storage.
