Abstract Patchouli oil comes from Tinombala village which has never been tested for the Indonesian National Standard (SNI). The purpose of this study was to determine the quality of patchouli oil by characterizing parameters of physical and chemical properties including color, refractive index, specific gravity, solubility in alcohol, acid number, ester number, iron content (Fe), and patchouli alcohol and alpha copaene content.. Sampling was done by random sampling. The results show a specific gravity of 25/25oC sample A = 0.9564, B = 0.9658, and C = 0.9590, refractive index (nD20) sample A = 1.5111, B = 1.5085 and C = 1.5086, the solubility in alcohol using ethanol of the three samples is >1:10 while using methanol 1:10, the acid number of the sample A=21.0375, B=9.1162 and C=19.6350, the ester number of the sample A=28,05, B=21.04 and C=21.04, iron (Fe) content of sample A=1.84210 mg/L, B=0.186842 mg/L and C=6.78950 mg/L, patchouli content alcohol sample A=,16,96%, B=15,52% and C=14,55% and for alpha copaene not detected. The results showed that the quality of patchouli oil in Tinombala village did not meet the Indonesian National Standard (SNI). Only the specific gravity, refractive index, and iron content are by the quality requirements, while the acid number and ester number and the main component determining the quality of patchouli oil, namely the patchouli alcohol content are still below the Indonesian National Standard, which is below 30%.

Main Component

The study to improve the quality of Indonesia betel leaves oil is done by treatment of citric acid and sodium carbonate. The treatment showed that the iron content and acid value were reduced optimally in the addition of 5% (w/w) citric acid (12 hours, 50oC) and 5% (w/w) sodium carbonate (9 hours, 50oC) yielded 0.45 mg/L of iron content and 1.00 mg/g of acid value, respectively. The main component of Indonesia betel leaves oil are 4-allyl phenylacetate. The descriptive sensory analysis showed that there were differences between betel leaves oil from Bogor compared with Boyolali and Makassar. There is a significant difference that the content of betel leaves oil from Bogor contains an isoeugenol compound of 20.71% while, Boyolali and Makassar contain eugenol of 17.02 and 19.21%, respectively. The study of the insect repellency indicated that Indonesia betel leaves oil potentially used as mosquito of Aedes aegypti repellent.

Anti-Oxidant Tests of starfruit and pineapple pulp on the quality of Used Cooking Oils   ABSTRACTUsed Cooking Oil is oil produced from frying residue and is carcinogenic because it causes oxidation, hydrolysis, and polymerization to produce toxic peroxides and free fatty acids that are difficult for the body to digest. Measurement of oil quality can be measured through 3 parameters, namely, the peroxide number, the acid number and the oil color. Efforts to control the quality of cooking oil are the addition of natural antioxidants, starch wuluh and pineapple pulp. Starfruit contains flavonoids, terpenoids, phenols and pectins as well as Vitamins C and A which can absorb free radicals in oil. Meanwhile, pineapple pulp contains high levels of vitamin C, flavonoids and polyphenols which can eat free radicals. This Research aims to determine the differences in the antioxidant power of starfruit and pineapple pulp to maintain the quality of used cooking oil. This research is experimental, which will study the antioxidant power of starfruit and pineapple pulp at the acid number, peroxidant and color intensity of used cooking oil. 3 grams of dry starfruit and 0.4 grams of dried pineapple pulp are added to each pad 100 mL of used cooking oil. The application of starfruit and pineapple pulp in used cooking oil had a significant effect on the 3 oil quality parameters, namely the acid number, the peroxide number and the oil color intensity, with a significance value of P <0.05. This is because the antioxidant content and composition of the two ingredients are different. Wuluh starfruit in the addition of 3 grams provides a fairly large antioxidant effect, while pineapple pulp at a concentration of 0.4 grams has shown anti-oxidant power so a higher concentration is needed to produce optimal antioxidant power. Keywords: Antioxidants, Starfruit, Pineapple Dregs

Natural edible oil derived from wild non-cultivated oil crops contributed to human daily nutritional diversity and disease prevention. It was important to investigate the nutritional value of these oils and the feasibility of crop cultivation. The present study focused on the assessment of seed oil quality of Sambucus williamsii Hance (SWH) and its molecular breeding. Wild SWH seed oil was extracted by supercritical CO2 technology and the composition of the oil was determined by using gas chromatography mass spectrometry (GC-MS) analysis. The oil content of SWH seeds reaches around 40%. Its seed oil was found to be rich in unsaturated fatty acids, such as 24.24% of linolenic acid and 50.56% of linoleic acid, and vitamin E (25.92 mg kg−1). The cytotoxicity and heavy metal analysis showed SWH seed oil was safe for consumption. In addition, the SWH strains with excellent characteristics were screened out for cultivation according to genetic diversity and morphological analysis. Amplified fragment length polymorphism (AFLP) markers were used to evaluate the genetic diversity of 28 accessions of wild SWH seeds and 5 accessions were selected to cultivate. Among them, two strains of SWH (sample 3 and 6) with high yielding (275.7 and 266.8 area yield kg−1) were suitable for dense planting and could be used to establish the raw material forest of SWH seed oil. The results of this study indicated the potential of development of selected SWH as novel oil crops and their wide cultivation.
