Abstract

Purple sweet potato (Ipomoea batatas L.) is one
of the tubers or roots that is widely grown in Indonesia that
contain high antioxidants. One type of flavonoid that functions as an antioxidant is a natural dye called anthocyanin.
In the process of extraction of anthocyanin, the solvent
has an important role. METHODS In this research, the deep
eutectic solvent was used because it is more economical
and environmentally friendly. This research will optimize
the microwave assisted extraction of anthocyanin content
in purple sweet potato (Ipomoea batatas L.) using a deep
eutectic solvent with the variation of material to solvent
ratio, microwave power, and extraction time. Optimization
is done by using the statistical method Response Surface
Method (RSM) with total anthocyanin content as a response.
RESULTS The optimum operating conditions for the extraction of anthocyanins from purple sweet potato using
the deep eutectic solvent were obtained at solid to solvent
ratio of 1:29 at microwave power of 270 watts for 193 s,
with an optimum TAC value of 311.64 mg/L and an antioxidant value of 44.85%. CONCLUSIONS The use of DES can
increase the extraction yield and is environmentally friendly
