Abstract
The comparison of aroma active compounds between three species of
banana which were pisang mas (Musa acuminata), pisang kepok (Musa
paradisiaca), and pisang batu (Musa balbisiana) were conducted by extracting it
using HS-SPME and be measured in order to know the volatiles and aroma active
compounds using GC-MS and GC-O with nasal impact frequency (NIF) method.
There were 20, 9, and 3 volatile compounds that were identified in pisang mas,
pisang kepok, and pisang batu respectively. The result of GC-O showed that there
were three aroma active compound (hexanal, isoamyl acetate, and isobutyl
butyrate) which contributed to green, grassy, fruity, banana-like, and sweet
aroma detected in pisang mas, three aroma active compounds (hexanal, 2-hexenal,
and isoamyl acetate) which contributed to green, grassy, fruity, sweet, leafy, and
banana-like aroma detected in pisang kepok, and two aroma active compounds
(isoamyl alcohol and isoamyl acetate) which contributed to pungent, sweet,
banana-like, and fruity aroma detected in pisang batu. QDA was also done in
order to know the sensorial analysis of the banana. The result of QDA showed
that banana-like, fruity, and sweet aromas were dominant in pisang mas while it
has less intensity in pisang kepok. It also showed that pungent, sour, green, and
grassy were the dominant aromas in pisang batu while it has less intensity in
pisang kepok. The result of QDA could be supported by the result of GC-MS-O.
This leads to the result of the preference choice using hedonic test of banana from
the consumer. The taste of pisang mas was preferred the most among the three
banana species. The aroma and overall preference of pisang batu was the least
preferred while the aroma and overall preference of pisang mas and pisang kepok
were not significantly different.
