“…The saponification number decreases with short chain elongation during the maturity of fruit. Our results with respect to variation in iodine value and saponification number are in accordance with those in developing C. inophyllum seeds [24]. The iodine value and saponification number of pongamia oil at 42 WAF is on a par with the values reported by Azam et al [34].…”

“…Some of the fatty acids like myristic acid (14:0), behenic acid (22:0), lignoceric acid (24:0), erucic acid (22:1) and arachidonic acids (20:4) detected only in trace amount (data not shown) and hence they were not included in the fatty acid profile. The variation in fatty acid profile of pongamia at different development stages were similar to variations observed in Calophyllum inophyllum [24]. In the early stages of seed development, palmitic acid and linoleic acid contents were high.…”

Oil content, fatty acid composition and karanjin content were studied in developing pongamia seeds, at intervals of 3 weeks from 30 weeks after flowering up to 42 weeks. Three marked stages in seed development were observed at the early green pod stage, the middle half brown stage and the late dark brown stage. Significant variation in seed biomass, pod and seed characteristics were observed. A significant (P \ 0.01) decrease in the moisture content of the seeds was observed during seed development. The oil content gradually increased from 32.06 to 36.53 % as the seed matured. A significant variation in fatty acid composition was detected across all stages of seed development. Palmitic acid (16:0) content marginally decreased from 11.81 to 10.18 %, while stearic acid (18:0) and linolenic acid (18:3) remained constant at all stages of seed maturity. A steady increase in oleic acid (18:1) content from 38.11 to 49.11 % was observed, while the linoleic acid (18:2) content decreased from 30.14 to 18.85 %. The iodine value increased, while the saponification number of oil decreased during seed development. The increase in karanjin content was steady. Seeds harvested after 42 week after flowering yielded the maximum oil with high oleic acid content which could be suitable for biodiesel production.

“…Further, it has positive bio-ameliorative effect on the nitrogen, phosphorous, potassium, and organic carbon content of soil. Calophyllum inophyllum L., a member of Clusiaceae family, is native to Australia and has many attributes to be used as a biodiesel feedstock [21]. It fruits profusely (3000-10,000 seeds tree À1 season À1 ) and requires little maintenance [22].…”

Biodiesel derived from plant species has been a major renewable source of energy and has received global interest mainly due to climate change issue. It has increasingly received worldwide attention as a promising alternative fuel. Growing interest in biodiesel production from edible oil brings scarcity in food supply. To overcome this problem, utilization of non-edible oils could be explored. Non-edible oil as biodiesel feedstock impressed in many factors such as energy sustainability and independence in certain areas, especially in rural community, creating job opportunities, elevating environmental merits, and avoiding monoculture of fuel resources. The present chapter reviews several such potentials, including fatty acid methyl ester (FAME) or biodiesel production process of nonedible oil resources as biodiesel feedstock in SouthEast Asian geographical region. The SouthEast Asian countries fall in the tropical region of the world and have many species as non-edible oil, viz., jatropha, karanja, polanga, neem, rubber, and mahua. The oils derived from these species have shown considerable potential as biodiesel feedstock.

“…Among various non‐edible oils, jojoba oil is considered to be a more sustainable source because it can be cultivated even in relatively hot weather with less water and low fertile soil 14 . Jojoba oil plants are abundant and available in various countries including India, South East Asia, Australia, East Africa, and the South Pacific 24,25 …”

Summary Magnesium‐alumina (Mg‐Al2O3) composite was synthesized by sol‐gel method. The SO42− catalyst supported Mg‐Al2O3 was prepared by three different methods such as solution, hydrothermal, and vapor phase. The as‐synthesized materials were characterized by different physicochemical techniques. The acid sites of Mg‐Al2O3 (10) composite were enhanced by depolymerization of triglyceride (jojoba oil) to produce free FFA. Catalyst prepared by hydrothermal methods exhibits high acid sites of 3.44 mmol g−1 of NH3. Sulfidation of catalysts play a vital role in the catalytic conversion of jojoba oil by methanol activation. SO42−/Mg‐Al2O3 (10) catalyst reveals 99% conversion efficiency tested under optimized conditions of jojoba oil to methyl ester (biodiesel). TGA result confirmed the S2/Mg‐Al2O3 (10) catalyst is stable upto 800°C and weight loss of 19.2%. The recyclability of the S2/Mg‐Al2O3 (10) catalyst reveals reasonably acceptable conversion efficiency after sixth cycle and this catalyst is found to be suitable for the industrial biodiesel production.
