Fatty acid profile as a means of authentication of beeswax / Siti Razilah Iskandariah
The objectives of this study were to study the different between fatty acid in beeswax from different geographical location and to determine amount of acid value in each of beeswax. Total seven (7) samples of beeswax each of type were analysed by using Gas Chromatography - Mass Spectrum (GC-MS)....

| Summary: | The objectives of this study were to study the different between fatty acid in
beeswax from different geographical location and to determine amount of acid
value in each of beeswax. Total seven (7) samples of beeswax each of type were
analysed by using Gas Chromatography - Mass Spectrum (GC-MS). The type of
fatty acid obtain is palmitic acid and stearic acid. The obtain result of ratio
palmitic acid per stearic acid (PA/SA) showed that beeswax from Terengganu
have (1.07), beeswax from Cameron highland (1.58), for commercial beeswax
(SOAP CELLAR, GREEN HERBALOGY, TAKE IT GLOBAL AND GALORE)
has an area ratio (0.84), (0.85), (2.45) and (2.33) respectively. For candle wax the
area ratio is (1.14). The highest and lowest area ratio come from commercial
beeswax. While for the beeswax the area ratio is average but for the candle waxes
the area ratio is quite high maybe when the production of candle waxes there is a
mixed with beeswax so that why the area ratio quite high. For the acid value
determination beeswax from Terengganu and Cameron highland is highest
(28.05mgKOH/g and 30.09mgKOH/g) than others. Candle wax is the lowest
amount of acid value (12.75mgKOH/g). |
