Efektivitas Asam Asetat dalam Ekstraksi Asam Fitat Pollard
Abstract: Phytate is commonly
high in cereals grain. This compound can be extracted with acid solution. The
purpose of this study is to extract phytic acid from pollard using acetic acid
at the concentration of 0.1, 0.5, 1, and 5%. Pollard was fractionated using
vibrator ball mill to evaluate the distribution of phytic acid in the particle
of pollard. One percent of acetic acid was used to extract phytic acid from
pollard at ratio of 1:1; 1:1.5; 1:2; and 1:3. The fraction having particle size
of 16, 30 and 50 mesh had similar phytic acid content. The results indicated that
phytic acid content of these fractions was higher than that of 100 and 400 mesh
fractions. Whole pollard had higher phytic acid content than its fractions.
Phytic acid in pollard can be extracted by 1% acetic acid solution. Extraction
of phytic acid from pollard using 1% acetic acid solution at ratio of 1:3
produced 23.83 g/kg.
