Abstract:

The extraction of oil from fixed beds of Canola seed ( Brassica napus and Brassica campestris ) was studied using carbon dioxide at temperatures and pressures ranging from 25 to 90°C and 10-36 MPa respectively. The highest oil solubility in the CO₂ (11 mg/g CO₂) was observed at 36 MPa and 55°C. The equilibrium oil concentration in the CO₂ phase, was found to be independent of the oil concentration in the seed phase. The extracts were found to be essentially free from phosphorus (<7ppm) and their fatty acid content did not change significantly as the extraction progressed. The total amount of

Abstract:

Cranberry seed oil is a fine quality oil which can be marketed for its many beneficial functions to human health due to the presence of a unique combination of omega- 3, 6 and 9 fatty acids and the high concentration of antioxidants. Although there is no available clear data about the oil percentage of cranberry seeds in literature, an experiment was done to analyze the oil yields obtained through different processes such as heat reflux, microwave and ultrasound, both quantitatively and qualitatively. During preliminary experiments, better oil yields were obtained with ground seeds (10.11 ± 0.

Abstract:

Dietary polyphenols have been positively correlated to the reduced risk of several chronic diseases, including Alzheimer' disease (AD). Grape (Vitis vinifera) seed contains 5-8 % polyphenols and annually, 2.5 million tonnes of grape seed is generated in the juice and wine industry. Grape seed extract (GSE) and its compounds gallic acid (GA), resveratrol (RSV) and epigallocatechin gallate (EGCG) have been shown to attenuate AD aetiological features including oxidative stress, protein aggregation, and mitochondrial dysfunction in cell and animal models.

Abstract:

Automatic bilingual lexicon extraction has many applications in Natural Language Processing, but often times requires highly structured,parallel, data or extensive bilingual seed lexicas to get reasonably good performance. Random Indexing models with a small bilingual seed lexicon could be used to perform (semi-)automatic lexicon extraction using only separate monolingual data. This thesis explores, explains and evaluatessuch a method of (semi-)automatic lexicon extraction on Random Indexing models using a small lexicon.

Abstract:

Growing energy demand in the world force people to investigate alternative energy sources. Unlike coal or other fossil fuels, renewable energy sources are promising for the future. Especially, seed oils are effectively used as energy sources such as fuel for diesel engines. The scope of this study is to develop an oil extraction machine specific to canola seed. In this study, seed oil extraction methods have been investigated and various alternatives for the extraction machine have been considered. For continuous operation, oil extraction with a screw press is evaluated as the most appropriate

The nuclear pore complex (NPC) is perhaps the largest protein complex in the eukaryotic cell, and controls the movement of molecules across the nuclear envelope.

The transmembrane ring sub-complex is composed of Nups responsible for anchoring the NPC to the nuclear envelope. Bioinformatic analysis has traced all major sub-complexes of the NPC back to the last eukaryotic common ancestor, meaning that the nuclear pore structure and function is conserved amongst all eukaryotes.

In the first part of this study, protein was extracted from defatted roselle seed and its characteristic was determined. Although defatted roselle seed possesses high protein content (34.20%), they are usually discarded as waste. The use of α-amylase pretreatment (1,800 units/g DRS for 6 h) before the extraction of protein resulted in 72.18% protein yield as compared to the 52.24% yield obtained without ??amylase pretreatment.

Abstract:

碩士<br>國立臺灣海洋大學<br>食品科學系<br>98<br>A high performance liquid chromatographic method for guantitative determination of ellagic acid (EA) from longan seed was developed. EA was eluted by using a polyethylene glycol (Supelco Discovery HS PEG, 25 cm × 4.6 mm) column. The mobile phase was composed of water and acetonitrile (70:30, v/v)(pH 2.5) and the Uv detector was set at 254 nm. Good separation of EA from other compounds in longan seed methaolic extract was obtained within 15 minuites. The methanolic extracts of seed of four longan cultivars (Fu Yen, Fenke, Ta Fen Ko and October) contained 2.6

Abstract:

The aim of this study was to develop a cost-effective process to produce a grape seed extract of high quality using only non-toxic extractants. When this study was started no grape seed extract was produced in South Africa. Large quantities were imported to supply the local demand in the human and animal herbal medicine industry. Grape seed extract is mainly used to boost the immune system of humans and animals based on its antioxidant activity. Initial work with different extractants established the polarity of the compounds with antioxidant activity. Antioxidant related activity was det

Unlike most other methods having their search domain to be the whole data-set, iso-contouring algorithm does its search only on a relatively small subset of the original data-set. This subset, called a seed-set, has the property that every iso-surface must intersect with it, and it could be built at the preprocessing time. When an iso-value is given at the run time, iso-contouring

Abstract:

Aqueous extraction of yellow mustard seed recovers oil in the form of oil-in-water emulsion. In this study, the ternary phase diagram of IPA, oil and water was developed to design an effective oil extraction process of oil-in-water emulsion. A 4-stage extraction process recovered 92.3% of oil from the emulsion into virtually anhydrous IPA-oil miscella. The oil and water separation and IPA usage efficiency was improved by using recycled solvent, but the oil recovery was decreased to 86.0%. The obtained IPA-oil miscella can be used directly in biodiesel production. The use of IPA as a reactant

Today we see everywhere that oil has become inherent part of our daily life. Every activity is dependent on the requirement of fuels be it directly or indirectly. The demand of fuels is increasing day by day. Import dependence for oil in India which is about 70 per cent, is likely to increase further. As we all know that the petroleum resources are limited and are non-renewable in nature, we must start to think about the alternatives as we are likely to run out of the petroleum resources in few decades or so. Stress must be given to production of energy from renewable sources as they are biode

Jatropha curcas L. is a drought-resistant plant which can be grown in poor soil and marginal lands. The use of Jatropha seed oil to produce biodiesel has been widely studied in recent years. Results showed that it is one of the most promising alternatives for conventional petro-diesel. Currently, hexane is still the most commonly used solvent for commercial oil extraction. However, the increasing price and flammability properties of hexane are motivating industry to seek alternative solvents. The objectives of this study are to design and analyze the Jatropha seed oil extraction for use in bio
