Abstract

Bougainvillea (Bougainvillea spectabilis Willd) and red ashoka (Ixora cocinea) flowers contains natural color pigment, namely anthocyanins. Anthocyanin levels in these two flowers are high enough so that can be used as natural color pigment. Anthocyanins can be used as an indicator for detection of borax food additives and formalin food preservatives. The subject of this research was creating a test media (test paper) of formaldehyde and borax from the extract of bougainvillea and red ashoka flowers. The test paper was used to analyze food samples such as sausages, kolang kaling fruit, wet noodles, meatball tofu, rambak crackers and tofu. The samples were selected based on the type of food consumed most often and survey, the type of food was mixed with dangerous substances, namely borax and formaldehyde. The anthocyanin content in the extract Bugenville flowers was 57.66 mg/100 g and extract Ashoka flowers was 8.66 mg/100 g. Screening of anthocyanin content in CEA was reacted with HCl, which resulted in a purple color change in the CEA of Bugenville flowers and in CEA of Ashoka flowers a bright red color change. The reaction of CEA with NaOH is a change in the bluish green color of the bougainvillea flowers and the CEA of the Ashoka flowers a green color change. Samples containing formaldehyde will change the color of the bougainvillea CEA test medium from magenta to deep purple and samples containing borax will change the color of the test medium to red. Samples containing formaldehyde will change the color of the red ashoka flower CEA test medium from red brown to bright red and samples containing borax will change the color of the media to green. The anthocyanin content in Bougainvillea flowers and Ashoka flower crowns can be used as a test medium (test paper) and is effective enough to be used as a test indicator for the content of formalin and borax in food.
