Telah dilakukan penelitian untuk menguji kualitas minyak biji adas (Foeniculum vulgare) yang diperoleh dengan metode soxhletasi. Biji adas dikenal sebagai allround flavoring agent karena memiliki aroma yang khas, sehingga banyak digunakan dalam bidang farmasi maupun industri.  Minyak adas tergolong dalam minyak atsiri dengan komponen utamanya anetol yang memberikan aroma yang harum. Penelitian ini bertujuan untuk menganalisis kualitas minyak biji adas yang dihasilkan dengan menggunakan metode soxhletasi. Biji adas diekstraksi dengan menggunakan metode soxhletasi. Rendemen yang diperoleh diuji kualitasnya berdasarkan standar Food Chemical Codex. Hasil penelitian menunjukkan rendemen rata-rata minyak biji adas adalah 34,95%. Minyak adas hasil soxhletasi yang diuji kualitasnya diperoleh hasil yang baik dengan nilai indeks bias 1,4779, bobot jenis 0,9873, kelarutan dalam alkohol 90% pada perbandingan 1:3 dan jernih pada perbandingan 1:7, dan bilangan asam rata-rata 2,81. Hal ini menunjukkan bahwa kualitas minyak biji adas dengan metode soxhletasi memberikan hasil yang baik.A research aimed to determine fennel (Foeniculum vulgare) seed oil quality obtained by soxhletation had been accomplished. Fennel seed is known as all round flavoring agent for its distinctive odour and it is widely used in pharmaceutical and industrial fields. Fennel oil is an aromatic oil that contains anetol as its main component which gives a fragrant aroma. The objective of this research was to analyze the quality of fennel seed oil produced by using soxhlet. The analysis was based on the description by Food Chemical Codex. The average yield of fennel seed oil was 34.95% with refractive index of 1.47798 and specific gravity of 0.98732. The oil was soluble in alcohol 90% at a ratio of 1:3 and produce a clear miscible liquid at a ratio of 1:7. In additon, it had acid number of 2.809. The results showed that good quality fennel oil could be obtained by soxhletation.

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.

Perilla Seed

Perilla seed oil has been attracting attention in South Korea as a health food. Five fatty acids of 100 Perilla accessions were identified as follows: palmitic acid (PA) (5.10–9.13%), stearic acid (SA) (1.70–3.99%), oleic acid (OA) (11.1–21.9%), linoleic acid (LA) (10.2–23.4%), and linolenic acid (LNA) (54.3–75.4%). Additionally, the 100 Perilla accessions were divided into two groups (high or low) based on the total fatty acid content (TFAC). By using an association analysis of 40 simple sequence repeat (SSR) markers and the six Perilla seed oil traits in the 100 Perilla accessions, we detected four SSR markers associated with TFAC, five SSR markers associated with LNA, one SSR marker associated with LA, two SSR markers each associated with OA and PA, and four SSR markers associated with SA. Among these SSR markers, four SSR markers (KNUPF14, KNUPF62, KNUPF72, KNUPF85) were all associated with TFAC and LNA. Moreover, two SSR markers (KNUPF62, KNUPF85) were both associated with TFAC, LNA, and OA. Therefore, these SSR markers are considered to be useful molecular markers for selecting useful accessions related to fatty acid contents in Perilla germplasm and for improving the seed oil quality of Perilla crop through marker-assisted selection (MAS) breeding programs.

The aim of this work is to study the effects of drying conditions on the quality of extracted pricly pear seed oil, specifically α-tocopherol content. Drying experiments were carried on following a full 23 factorial design using a vertical drying tunnel. The temperature range was 45 to 70°C, relative humidity range was 15 - 30% and   air velocity was 1 and 2 m/s. The Midilli-Kucuk model was found with satisfaction describing the seed air drying curves with a correlation coefficient of 0.999 and a standard error of 0.01. For each drying condition, the extraction of fixed oil seeds was performed at cold using mechanical pressing method. The oil quality was evaluated on the basis of the a-tocopherol content. The a-tocopherol was identified and quantified by high-performance liquid chromatography (HPLC-UV). According to the experimental results, it was found that convective drying of thin layer of seeds at soft air conditions, drying temperature of 45°C, relative humidity of 15% and air velocity of 1m/s give the optimal quality of extracted oil in terms of a-tocopherol content.Keywords: prickly pear seeds;  convective drying; semi-empirical modeling; a-tocopherol seed oil; optimization.
