Abstract

Coffee consumption is increasing and it has become part of people’s lifestyle, so there is a need for an innovation in coffee making with the addition of local ingredients such as tiwai onions. This study analyzed the chemical profile using FTIR and the antioxidants of coffee, tiwai and their mixtures. FTIR results show that roasted coffee is compared to green coffee (without roasting) the components remain the same, there is only a slight change in the absorbance reduction, FTIR results in the wave number range of 2800 to 3000 in roasted ground coffee there are two curves but after being mixed with tiwai powder only one absorption curve is 2936.09 at 0.14 absorbance. Green coffee powder, roasted coffee powder, tiwai powder, mixture of tiwai powder and roasted coffee powder, and coffee powder mixture with instant tiwai each have antioxidant components, especially in the absorption of O-H bonds which form phenol compounds (flavonoids). The highest antioxidants were green coffee powder, roasted coffee powder, tiwai powder, mixed roasted coffee powder with tiwai powder, and roasted coffee powder with instant tiwai, respectively.
