EFEKTIVITAS PENGGUNAAN JENIS PELARUT DAN ASAM DALAM PROSES EKSTRAKSI PIGMEN ANTOSIANIN KELOPAK BUNGA ROSELLA (Hibiscus sabdariffa L)
ABSTRACT: Anthocyanin is
pigments are red, purple and blue that commonly found in plants and can be used
as a natural dye. One kind of plant that can be extracted as a source of
natural dyes and contain anthocyanin is rosella petals flower. The use of
solvents and acids are the factors that determine the quality and quantity of
anthocyanin that extracted from rosella petals flower. Therefore in this study
will be assessed the influence of the use of appropriate solvents and acids in
the process of extraction of anthocyanin from rosella petals flower. Types used
are varieties rosella sabdariffa. This research was conducted using Randomized
Block Design Factorial consisting of 2 factors that is the type of solvent (J)
consisting of ethanol and methanol, as well as the second factor which is the
type of acid (P) consisting of tartaric acid, citric acid, and acid acetate.
Based on the analysis it was found that the anthocyanin pigment (in red) in rosella
petals flower is more stable in the acidic conditions (low pH). Type of acid
(P) gives a very significant influence (P ≤ 0.01) toward pH values and
significant influence (P ≤ 0.05) toward the intensity of the color. Type of
solvent (J) that used gives a very significant influence (P ≤ 0.01) toward the
intensity of the color, as well as a significant influence (P ≤ 0.05) on yield
and levels of anthocyanin
