Bunga kamboja cendana merupakan salah satu jenis bunga kamboja yang paling disukai di Bali karena aromanya lebih harum dibanding jenis kamboja yang lain. Biasanya bunga kamboja cendana digunakan sebagai pengharum ruangan dan untuk kelengkapan upacara di Bali. Aroma harum bunga kamboja cendana disebabkan kandungan minyak atsiri di dalamnya yang dapat diekstrak dari bunga dengan proses distilasi.Telah dilakukan penelitian mengenai pengaruh lama distilasi terhadap komposisi minyak atsiri bunga kamboja cendana. Tujuan penelitian ini adalah untuk mengetahui perbedaan komposisi minyak atsiri bunga kamboja cendana yang dihasilkan dari proses distilasi pada lama proses yang berbeda. Bunga kamboja cendana segar diiris, selanjutnya didistilasi dengan metode distilasi uap air. Distilasi dilakukan pada lama proses 1, 2, 3, 4, 5 dan 6 jam. Minyak atsiri yang dihasilkan selanjutnya dianalisis dengan GC-MS. Hasil analisis menunjukkan bahwa minyak atsiri bunga kamboja cendana yang dihasilkan pada lama distilasi berbeda mempunyai komposisi senyawa yang berbeda. Senyawa penyusun minyak atsiri bunga kamboja cendana yang dihasilkan dari proses distilasi dengan lama proses berbeda, mempunyai persentase relatif yang bervariasi. Namun sebagian besar tersusun dari jenis senyawa yang sama yang tergolong dalam senyawa alkana, alkena, alkohol dan aldehid. Lima senyawa utama yang merupakan penyusun terbesar minyak atsiri kamboja cendana yaitu nonadecana (4,87 – 7,71%), patchouli alkohol (4,87 - 15,23%), octadecenal (2,82 – 15,93%), octadecana (6,35 – 6,39%) dan eicosane sebesar 6,35- 19, 39%.Kata kunci : bunga kamboja cendana , Plumeria alba, essential oil ,distillation time

Chemical Composition of Essential Oil of Cendana Frangipani Flower (Plumeria alba) With Re-Extraction Using Ethanol Solvents Ni Made Wartini; GP Ganda Putra; Putu Timur Ina
Agroindustrial Journal Vol 3, No 2 (2014)
Publisher : APTA and DTIP FTP UGM

One potential source of essential oils in Bali which has not been developed is from cendana frangipani flower. Cendana frangipani flower has a very distinctive scent and very popular in Bali, it has an important function in the local culture, used as fragrances, incense (prayer facilities especially in Bali), and as an air freshener aromatherapy in the spa industry. The fragrance is typical due to their volatile oil which content in the cendana frangipani flower. The quality produced of essential oils are determined by their chemical composition of the extraction process. Previous research indicates that the good quality of frangipani immature essential oil extractedthrough the extraction process using hexane resulting in concrete form which still has the solvent aroma, semi-solid consistency and dark yellow. Therefore, it is necessary tomodifythe process by changing the concrete into the absolute product by re- extraction using ethanol.The purpose of this study was to determine the differences in chemical composition of essential oils of cendana frangipani flowers resulting from the re-extraction by using a particular comparison between ethanol and concrete. Fresh cendana frangipani flowers were sliced and then extracted with n-hexane in a Soxhlet extractor toproduce concrete volatile oil. The concrete was further re-extracted using absolute ethanol to produce essential oil with a concrete and ethanol comparison treatment consisting of 1:4, 1:6, 1:8, and 1:10. Absolute essential oil were then analyzed by GC-MS. The analysis showed that the absolute cendana frangipani flower essential oil produced by different treatment has a different compounds composition and relative percentages varied. The chemical composition of cendana frangipani absolute essential oils was classified as alcohols, terpenes, ketones, esters, and acid with the concentration from 2.65 to 24.77%;0.34 to 1.35%; 0 to 1.38 %; 13.38 to 24.23% and from 22.74 to 58.15% respectively.

Virgin coconut oil (VCO) is oil obtained from fresh old coconut and processed by squeezing with or without the addition of water, without heating or heating no more than 60oC and safe for consumption. This research was aimed for determining the effect of yeast type and fermentation time on the characteristics of virgin coconut oil and decided yeast type and fermentation time to produce the best characteristics of virgin coconut oil. The research based on a factorial Randomized block design (RBD) with the first factor was the type of yeast, namely bread yeast and tempeh yeast, and the second factor is the fermentation time, namely 24 hours, 36 hours, and 48 hours. Each combination treatment was replicated 3 times to obtain 18 experimental units. Data was analyzed using analysis of variance and if the treatment had a significant effect, its followed by the Duncan multiple range test (DMRT). The variables observed in this research were yield, moisture content, turbidity, free fatty acids (FFA), peroxide number, and flavor (hedonic and scoring). The results showed that interaction of yeast type and fermentation time had a significant effect (P<0.05) to yield and moisture content VCO. Types of bread yeast and tempeh yeast with 24 hours, 36 hours, and 48 hours of fermentation have a significant effect (p<0.05) on the aroma of VCO (hedonic and scoring). Type of tempeh yeast with a fermentation time of 36 hours for producing virgin coconut oil the best characteristics with yield 36.67%, moisture content 0.16%, turbidity 0.08%, free fatty acids 0.10%, peroxide number was not detected, coconut scent and liked.

Red dragon fruit has the potential as a functional food because it contains bioactive compounds that provide health benefits. Dried fruit is a simple processing fruit method and does not change the shape of the fresh fruit much, but during the drying process, the bioactive compounds are easily damaged by heat. It is necessary to give pre-treatment before drying. The study aimed to determine the antioxidant capacity, total phenolic, total flavonoid, betacyanin levels, and sensory preference of dried red dragon fruit with pre-treatments. The six levels of pre-treatments were without pretreatment/control (K0), steam blanching (70ºC) for 10 minutes (K1), soaking in cold citric acid (3%) for 10 minutes (K2), soaking in cold citric acid (3%) for 3 minutes, then steam blanching at 70ºC for 7 minutes (K3), soaking in cold salt (5%) for 10 minutes (K4), and soaking in cold salt (5%) for 3 minutes, steam blanching at 70ºC for 7 minutes (K5), then dried it at 50ºC for 18 hours. The results showed that the control (K0) had the highest total phenolic content (20.10 mg GAE/g), total flavonoid content (5.92 mg QE/g), betacyanin content (1.57 mg/g), antioxidant capacity (1.72 mg GAEAC/g), and organoleptic preference like of color (5.65), rather like of odor (5.00), like of texture (5.69), like of taste (5.92), and like of overall acceptance (5.92). Based on sensory (organoleptic) acceptance, the steam blanching (70ºC, 10 minutes) (K1) of dried red dragon fruit had the highest preference: like of color (6.08), like of texture (5.85), like of taste (6.23), and like of overall acceptance (6.23), but rather like of odor (5.31). Meanwhile, KI had 16.71 mg GAE/g of total phenolics, 4.98 mg QE/g of total flavonoids, 0.87 mg/g of betacyanin levels, and 1.48 mg GAEAC/g of antioxidant capacity. Dried red dragon fruit (especially with steam blanching) has the potential as a functional food ingredient because the pre-treatment maintains its bioactive content during drying. Keywords: dried red dragon fruit, functional food ingredients, pre-treatment
