Abstract

Vitamin C is one of the nutrients that act as antioxidants derived from fruits and green vegetables, such as the broccoli (Brassica oleracea L.). This study aims to warming influence on levels of vitamin C in broccoli (Brassica oleracea L.) with qualitative and quantitative analysis. Qualitative analysis was performed using specific reagents that ammonium molybdate, Fehling Fehling's A and B which have indicated a positive sample containing vitamin C, and vitamin C were analyzed quantitatively using UV- Vis spectrophotometry at a wavelength of 570 nm. The results showed levels of vitamin C in raw broccoli 0.62915 mg/g and steamed broccoli 0.45449 mg/g.

Abstract

Rhodamine B is a synthetic dye used as a textile dye. It is prohibited as a Food Additive because it can irritate the digestive tract, poison, and even cause cancer and death. The research was to see if there were any Rhodamine B deposits of cotton candy in Makassar. This test used five samples. The methods used in testing are TLC and spectrophotometry UV-Vis. All five samples' test results show no stain was formed (negative). UV-Vis spectrophotometry test on a 553 nm length acquired data of Rhodamine B levels in a row as follows: first sample of cotton candy = 0.005%, sample 2 of cotton candy = 0.001%, sample 3 of cotton candy = 0.0008%, sample 4 of cotton candy = 0.003%, and sample 5 of cotton candy = 0.0009%. They concluded that all five samples identified contained Rhodamine B synthesized dye to a minimal degree of the cotton candy sample distributed in Makassar.
