EKSTRAKSI DAN UJI STABILITAS ZAT WARNA DARI KULIT BUAH ALPUKAT (PERSEA AMERICANA MILL) DENGAN METODE SPEKTROSKOPI UV-VIS
Abstrak: The avocado skin
fruit (Persea americana Mill) is one of species of Lauraceae family that had
many benefits and efficiacy for human. Avocado is a woody plant, the life cycle
can reach decades and were known to have potential as pigmen. The purpose of this
study is to extract and determine the stability of pigmen from avocado skin
fruit (Persea americana Mill) with UV-Vis Specroscopy methode. The extraction
was done with soxhlet method using ethanol. The result of soxhlet was 142,13 gr
avocado skin fruit dried powder was gained 88,85 gr ethanol extract. The
ethanol extract of avocado skin dried powder was concentrated using rotary
avoporator was gained 47,93 gr. The result phytochemical study, shown that
ethanol coarse contained of Tannin compound, flavonoids and antosianin. The
study stability of pigmen from avocado skin fruit (Persea americana Mill)
extract was done to temperature effect were 40oC, 50oC, 60oC, 70oC and 80oC, pH
effect were 3, 4, 5 and 6 and long storage effect were 1, 2, 3, 4 and 5 days at
wave length 200-400 nm. The observational data were analyzed by ANOVA followed
by Duncan test..
