“…There are several methods to produce oil from the seed including mechanical pressing, supercritical fluid extraction, supercritical CO 2 and solvent extraction (Talansier and others 2008; Han and others 2009; Tan and others 2009; Marasabessy and others 2010). Solvent extraction is the primary method currently used by the oil extraction industry.…”

The study revealed that tomato seed which is typically treated as a low value byproduct of tomato processing has great potential in producing oil with high antioxidant capability. The impact of processing conditions including time, temperature, solvent-to-solid ratio and particle size on yield, and antioxidant activity of extracted tomato seed oil are reported. Optimal conditions and models which describe the extraction process are recommended. The information is vital for determining the extraction processing conditions for industrial production of high quality tomato seed oil.

“…The crab paste was prepared as described previously (Marasabessy et al 2010 ). To extract oil, 2.0 g of crab paste was mixed with 30.0 g of kernel slurry and incubated in a orbital shaker at 37 °C, 150 rpm for 24 h. Antibiotics were applied in some samples as described previously and the extracted oil was assayed gravimetrically (Marasabessy et al 2010 ).…”

“…We demonstrated earlier that thermophilic strains isolated from the gut of paddy crabs, one of which was identified as Bacillus licheniformis , enhanced oil liberation up to 60% from aqueous J. curcas kernel, most likely via protein degradation (Marasabessy et al 2010 ), which would be disadvantageous for protein recovery. In the present report, we confirmed that these thermophilic bacteria degraded extracted J. curcas protein.…”

We investigated the use of bacterial cells isolated from paddy crab for the extraction of oil from Jatropha seed kernels in aqueous media while simultaneously preserving the protein structures of this protein-rich endosperm. A bacterial strain—which was marked as MB4 and identified by means of 16S rDNA sequencing and physiological characterization as either Bacillus pumilus or Bacillus altitudinis—enhanced the extraction yield of Jatropha oil. The incubation of an MB4 starter culture with preheated kernel slurry in aqueous media with the initial pH of 5.5 at 37 °C for 6 h liberated 73% w/w of the Jatropha oil. Since MB4 produces xylanases, it is suggested that strain MB4 facilitates oil liberation via degradation of hemicelluloses which form the oil-containing cell wall structure of the kernel. After MB4 assisted oil extraction, SDS-PAGE analysis showed that the majority of Jatropha proteins were preserved in the solid phase of the extraction residues. The advantages offered by this process are: protein in the residue can be further processed for other applications, no purified enzyme preparation is needed, and the resulting oil can be used for biodiesel production.

“…VCO is obtained from the fresh, matured coconut kernel by mechanical or natural means, with or without heat, without refining, bleaching and deodorization, which do not lead to the alteration of the natural oil [8]. Traditionally many methods are there for processing of coconut in wet basis like applying of temperature, alteration of pH (extreme acidic to basic), chilling and centrifugation, incorporation of enzymes [9], microbes such as L. plantarum [10], natural fermentation [11], supercritical fluid extraction [12], using crab paste as traditional java method [13], using acetic acid [14] were reported. The methods which are practiced in all the cases of wet processing are not according to APCC or any other standard specifications for the production of VCO.…”

Commercially, many methods are adopted for the production of the Virgin Coconut Oil (VCO). Nowadays, natural fermentation is widely employed to produce VCO in wet processing. But the problem in natural fermentation process has much contamination, due to surplus micro organisms present in natural environment, which leads to the poor quality of VCO. To overcome this, usage of probiotic organism like Lactobacillus fermentum is more beneficial for the fermentative production of VCO. Fermentation studies were conducted scientifically in computer controlled bioreactor to determine the effect of pH, temperature, inoculum concentration, oxygen requirement and incubation time on the yield of VCO. Yield efficiency of VCO in each parameter was determined. The pH of 5 ± 0.1, temperature at 45 ± 0.1 °C, inoculum concentration of 2%, fermentation end time of 48 hrs and microaerophilic conditions are the most suitable parameters for the superior production of VCO.
