Abstract
Sianida (CN-
) merupakan senyawa yang berpotensi fatal dan
dapat menyebabkan gangguan kesehatan. Singkong (Manihot esculenta
Cranz) mengandung senyawa glukosida sianogenik (CNglc) seperti
linamarin dan lotaustralin. CNglc membebaskan hidrogen sianida
(HCN) melalui hidrolisis oleh enzim degradatifnya yang umumnya
terlokalisasi secara terpisah dari CNglc. Tujuan dari penelitian adalah
untuk mengetahui ada atau tidaknya sianida pada umbi singkong, kadar
sianida yang terkandung pada umbi singkong, tepung singkong, dan
tepung yang sudah diolah menjadi makanan (enbal goreng).
Metode yang digunakan pada penelitian ini adalah
spektrofotometri UV-Vis dengan menambahkan ninhydrin 1%, Na2CO3
5%, dan NaOH 2,5 M dalam filtrat sampel membentuk warna biru.
Kemudian dilakukan uji validasi metode meliputi uji linearitas, LOD &
LOQ, Presisi dan akurasi. Hasil data dianalisis dengan menggunakan
metode one way ANOVA.
Kadar HCN pada umbi singkong 10,38 mg/kg sedangkan tepung
pada waktu perendaman 30 menit dan 1 jam yaitu 3,67 mg/kg dan 3,06
mg/kg kemudian enbal goreng dari masing-masing tepung yaitu 3,60
mg/kg dan 2,83 mg/kg. Diperoleh nilai linearitas 0,999, nilai LOD dan
LOQ yaitu 0,040 dan 0,120. Nilai presisi 0,39% dan nilai akurasi
100,31%. Hasil analisis menggunakan one way ANOVA terdapat
perbedaan dengan nilai signifikan ˂ 0,05. Berdasarkan hasil penelitian
perlakuan yang paling berpengaruh terhadap kadar sianida pada sampel
terdapat pada perendaman 1 jam.
Cyanide (CN-
) is a potentially fatal compound and can cause
health problems. Cassava (Manihot esculenta Cranz) contains
cyanogenic glucoside compounds (CNglc) such as linamarin and
lotaustralin. CNglc liberates hydrogen cyanide (HCN) through
hydrolysis by its degradative enzymes which are generally localized
separately from CNglc. The aim of the research was to determine the
presence or absence of cyanide in cassava tubers, the cyanide levels
contained in cassava tubers, cassava flour, and flour that has been
processed into food (fried enbal).
The method used in this research was UV-Vis spectrophotometry
by adding 1% ninhydrin, 5% Na2CO3, and 2.5 M NaOH to the sample
filtrate to form a blue color. Then a method validation test was carried
out including linearity, LOD & LOQ, precision and accuracy tests. The
data results were analyzed using the one way ANOVA method.
HCN levels in cassava tubers was 10.38 mg/kg, while the flour
during soaking for 30 minutes and 1 hour were 3.67 mg/kg and 3.06
mg/kg, then fried enbal from each flour was 3.60. mg/kg and 2.83 mg/kg.
The linearity value obtained was 0.999, the LOD and LOQ values were
0.040 and 0.120. The precision value is 0.39% and the accuracy value is
100.31%. The results of the analysis using one way ANOVA showed
differences with a significant value of ˂ 0.05. Based on the research
results, the treatment that had the greatest influence on cyanide levels in
the samples was soaking for 1 hour.
