The Processing Effects of Anthocyanins Extracted from Dragon Fruit (Hylocereus polyrhizus) Peel on Total Amount of Anthocyanins and SEM Image in Poultry Nutrition
The Processing Effects of Anthocyanins Extracted from Dragon Fruit (Hylocereus polyrhizus) Peel on Total Amount of Anthocyanins and SEM Image in Poultry Nutrition
The purpose of present study was to know the effects of different processing of anthocyanin content and scan electron microscope image of anthocyanin of dragon fruit peel in poultry diet. The experiment was performed in a completely randomized design with different processing like untreated dragon fruit peel or control, physical, chemical, biological, and physical-biological, and each treatment was replicated 4 times. Variables measured were total amount of anthocyanin and anthocyanin image of dragon fruit peel. The results indicated that physical treatment significantly increased anthocyanin content of dragon fruit peel. Furthermore, treated dragon fruit peel with chemical, biological, and combination of physical-biological significantly reduced anthocyanin content. The image of anthocyanin from each treated processing revealed that control image was similar to physical treatment, and it was different from other treatments. The physical treatment was the best method to increase anthocyanin content, and did not change the image of anthocyanin from dragon fruit peel.Keywords: Anthocyanins, Dragon fruit peel, Processing, Scanning electron microscope, Spectrophotometry
