Abstract

The part of dragon fruit that is used is only the flesh of the fruit for direct consumption or processing as other food products, while the peel is just thrown away. Based on several research results, red dragon fruit peel is a rich source of polyphenols and antioxidants. The antioxidant activity of the red dragon fruit peel is greater than the activity in the flesh, so the dragon fruit peel can be used as a natural herbal medicine by utilizing the antioxidants inside. The more dragon fruit peel extract is added, the pempek's shelf life is longer than without the addition of dragon fruit peel extract (control), the use of vacuum plastic can increase the shelf life of pempek. Keywords: dragon fruit peel extract, pempek, physical properties, chemical properties

Abstract

The potential of red dragon fruit peels both in terms of antioxidant activity and as sufficient food coloring promising. On the other hand antioxidants, one of which is vitamin C, is very susceptible to high heat. This study aims to determine the content of proximate, fiber and vitamin C from dry bakpia substitution of dragon fruit peels flour. A randomized block design with 4 replications was selected in this study, while the treatment consisted from 3 levels of dragon fruit peels flour substitution, namely 1%, 2%, 3% and control (0%). The results showed substitution of dragon fruit peels flour has no effect on water content, protein, fat, fiber and vitamin C dry bakpia. The 3% substitution of dragon fruit peels flour produces lower carbohydrate levels and significantly different with control, 1% and 2%. The ash content of 3% substitution of dragon fruit peels flour is higher and than significantly different with control and 1% but not significantly different with 2% . The conclusion was substitution of dragon fruit peels flour can be applied to 1- 2% of flour need to increase its nutritional value. Keywords: dragon fruit peels flour, dried bakpia, proximate, fiber, vitamin C
