BY EXTRACTION
The paper presents the results obtained by extraction of anthocyanins
from red cabbage by different methods (Soxhlet extraction, extraction under
microwave irradiation, ultrasonic extraction, extraction by boiling). It presents a
method for analysis of extracted compound using VIS spectroscopy. The
variation of optical properties of the extract depending on pH is also presented.
