In this work, the quantitative estimation of fatty acids in sesame and perilla oil by high performance liquid chromatography (HPLC) was investigated. The analysis of fatty acids were separated by HPLC using a differential refractometer as a detector. With micro Bondapak $C_{18}FFAA$ column and acetonitril, chloroform and tetrahydrofuran mixture as a solvent. In the fatty acid compositions, sesame oil was composed mainly of linoleic and oleic acids 49.6 % and 34.7%. In perilla oil, the amounts of oleic, linoleic and linolenic acids were 13.6%, 14.5% and 63.8%, respectively.

Peanut is one of the principal oil seeds in the world as a rich source of edible oil and protein. Peanut quality arises as a result of a complex interaction of genetic, physiological and biochemistry processes that produce the chemical composition of the peanut seed. The major factors influencing seed quality are degree of maturity and digging and drying, curing and storage as a series of harvesting. The end products, peanut butter, salted seed, confections, roasting stock and by-products are favored in world-wide because of their unique roasted peanut flavor, Literatures are reviewed mainly focusing on the physiological properties and nutritional quality of oil, protein and flavor in peanut. Chemical properties of protein and oil, and volatile flavor component in peanut seeds are studied. The objectives of this paper were to review and summarize the results obtained from the improving quality breeding program and evaluation of the chemical composition in peanut up to now.

To decrease environmental damage, the development of environmental friendly fluids provides attractive alternative to the conventional fluids. In this study, the effects of harmful ingredients (Cl, S) contained in the fluids that used in grinding and cutting processes to influence on the nasal cavities of the white rats were measured indirectly. Also, the level of the environmental influence in workshops was graded through analyzing the concentration and chemical ingredients of flying-dust, which generated from the friction and combustion in the cutting process, that for analyzing how harmful the influence of particles to workers then it could be used as the basic data for improving the environment. To improve the conventional machining fluid, which can be harmful on worker's bodies and the environment, the environmental friendly machining method was suggested through analyzing each lubrication properties of vegetable fluid and used-edible oil as alternative fluid. As a result, it was known that an emulsion type fluid might be the main cause leading to some respiratory ailments. Also this paper presents the possibility to use vegetable fluid and used-edible oil as the alternative of cutting fluids.

The effluents from industries processing vegetable oils are extremely rich in sulfates, often exceeding the maximum concentration allowed to release them to the environment. Biological sulfate reduction is a promising alternative for the removal of sulfates in this type of wastewater, which has other particularities such as an acidic pH. The ability to reduce sulfates has been widely described for a particular bacterial group (SRB: sulfate-reducing bacteria), although the reports describing its application for the treatment of sulfate-rich industrial wastewaters are scarce. In this work, we describe the use of a natural SRB-based consortium able to remove above 30% of sulfates in the wastewater from one of the largest edible oil industries in Peru. Metataxonomic analysis was used to analyse the interdependencies established between SRB and the native microbiota present in the wastewater samples, and the performance of the consortium was quantified for different sulfate concentrations in laboratory-scale reactors. Our results pave the way towards the use of this consortium as a low-cost, sustainable alternative for the treatment of larger volumes of wastewater coming from this type of industries.

The whole berry, pulp, and seed of sea buckthorn fruit were extracted with supercritical $CO_2$ to produce edible oils. The effects of extraction pressure, temperature, and $CO_2$ flow rate on the oil yield and extraction rate were investigated, and the fatty acid composition, tocopherol, and carotenoid contents of the oils were compared. The results showed that the extraction rate was affected by pressure, temperature, and $CO_2$ flow rate and, in general, the yield increased with a rise in any of the 3 variables. Fatty acids in the whole berry and pulp oil were dominated by monounsaturated fatty acids (>64%), followed by saturated fatty acids (about 30%). In contrast, fatty acids in the seed oil consisted mainly of polyunsaturated (>60%) and monounsaturated fatty acids (>24%). The seed oil had a slightly higher content of tocopherols, but a much lower content of carotenoids, compared with the whole berry or pulp oil.

The use of inedible vegetable oils as substitute for diesel fuel in compression ignition engine is of significance because of the great need for edible oil as food, and the reduction of biodiesel production cost etc. Jatropha curcas oil which is a leading candidate for the commercialization of inedible vegetable oils is selected in this study for reviewing the application in CI engine as an alternative fuel. The important properties of jatropha oil (JO) and JO biodiesel are summarized from the various sources in the literature. It is found that five different types of alternative fuel from JO such as neat JO, JO blends with diesel or other fuel, neat JO biodiesel, JO biodiesel blends with diesel or other fuel and degummed JO were extensively examined in the diesel engine. Two different application types of alternative fuels from JO such as preheating and dual fuelling were also tested, It should be pointed out that most of these applications are limited to single cylinder conditions. The systematic study for the selection of effective application method is required. It is clear that the blends of JOME and diesel can replace diesel fuel up to 10% by volume for running the existing common rail direct injection systems without any durability problems. The systematic assessment of spray characteristics of different types of JO and its derivatives for use as diesel engine fuel is also required.

Citrus계 식용 코팅제인 beeswax-hydroxypropyl methylcellulose(BW-HPMC), soybean oil-carboxymethyl cellulose(SBO-CMC), carnaubawax-shellac-locust bean gum(CW-SL-LBG)를 각각 사용하여 레몬에 먼저 1차 코팅하고 항산화제인 비타민 C와 E를 섞어 그 위에 제 2차 코팅하여 이중층의 multilayered 레몬을 제조하였다. 레몬 껍질 위에 형성된 막의 양은 CW-SL-LBG, BW-HPMC, SBO-CMC의 순으로 높게 나타났다. 가속 저장 실험 조건으로 30${^{\circ}C}$의 항온기에 12일 동안 저장하면서 유자의 중량감소율, 부패율, 경도, pH, 가용성 고형분, 적정산도, 갈변도의 변화를 측정하고 관능검사를 실시하였다. 중량감소율, 부패율, 경도, 갈변도는 CW-SL-LBG가 가장 작은 변화를 보였고, pH, 가용성 고형분, 적정산도의 변화는 SBO-CMC가 가장 작게 나타났다. 저장성의 관능검사에서는 CW-SL-LBG가 가장 양호하게 나타났다. 결과적으로 CW-SL-LBG가 비타민 C와 E를 함유한 multilayer 코팅에 가장 적합한 물질로 평가되었다.
