Abstract
Pewarna makanan merupakan bahan tambahan pangan yang
ditambahkan ke dalam makanan untuk meningkatkan penampilan dan
memberikan warna pada makanan. Pewarna makanan menjadi sorotan
utama ketika suatu makanan menampakkan warna yang cantik untuk
menggugah selera konsumen. Penelitian ini bertujuan untuk
mengembangkan metode penetapan kadar yellow fcf, red allura,
methanil yellow dan tartazin secara simultan.
Metode penelitian yang digunakan pada High Performance
Liquid Chromatography (HPLC) dengan fase terbalik. Fase gerak yang
digunakan buffer fosfat : asetonitril dengan bahan baku pewarna yellow
fcf, red allura, methanil, tartazin dan juga sampel makanan dan
minuman yang berada di Supermarket. Parameter optimasi meliputi
panjang gelombang, pH fase gerak, komposisi fase gerak, dan laju alir.
Parameter validasi termasuk linearitas, akurasi, presisi, selektivitas dan
LOD LOQ.
Hasil penelitian menunjukan bahwa penetapan kadar pewarna
seyawa yellow fcf, red allura, methanil dan tartazin secara simultan
dengan HPLC mendapatkan hasil optimum pada panjang gelombang
terdapat 508 nm, fase gerak buffer fosfat dan asetonitril (5:5) dengan
pH 8,8 dan laju alir 0,71 mL/menit, dan hasil dari validasi linieritas
yang di dapat 0,9997- 0,9998, akurasi 92%- 130,5%, RSD 0,84-1,55%.
Hasil penelitian dengan penetapan kadar secara simultan yang didapat
adanya beberapa senyawa yang melebihi batas maksimum yang telah di
tentukan yaitu pewarna tartazin pada sampel minuman bubuk, manisan
mangga dan tahu kuning.
Food dyes are food additives that are added to foods to enhance
the appearance and color of foods. This research aims to develop a
method of determining the levels of yellow fcf, red allura, methanyl
yellow and tartazin simultaneously.
Research method used on High Performance Liquid
Chromatography (HPLC) with reverse phase. Movement phases used
phosphate buffers: acetonitril with raw materials yellow fcf, red allura,
methanil, tartazin and also samples of food and beverages that are in
the supermarket. Validation parameters include linearity, accuracy,
precision, selectivity and LOD LOQ.
The results of the study showed that the determination of the
colouring levels of yellow fcf, red allura, methanil and tartazin
simultaneously with HPLC obtained the optimum results at
wavelengths of 508 nm, phosphate and acetonitril buffer phase (5:5)
with pH 8.8 and flow rate of 0.71 mL/min, and the validation of
linearities at 0.99-97-0.9998, 92%- 130,5%, RSD 0.84-1,55%. The
result of the research with the simultaneous determination rate of the
presence of several compounds that exceeded the maximum limits that
have been established in the coloring agent is tarzine in the sample of
beverage powder, mango and yellow.
