摘要

大豆是巴西中西部地区种植的主要油料种子,曾经的地理气候条件有利于它的种植,还有一些未被开发的物种,如克拉姆、油籽萝卜和尼日尔。因此,本研究拟采用两种定量方法,采用气相色谱法结合火焰电离检测器,对大豆、豆蔻、油籽萝卜和黑油的脂肪酸含量进行评价和比较,并进行多元统计分析,确定所选油籽之间的相似性,为这些油籽的最佳选择和应用提供安全信息。苎麻、油籽萝卜和黑籽的含油量分别为44.7% (m/m)、42.45% (m/m)和28.19% (m/m)。黑油和大豆油的主要脂肪酸为亚油酸(分别为66.9%和52.07% m/m),苎麻和油籽萝卜的主要脂肪酸为芥酸(分别为65.29%和33.54% m/m)。此外,除了黑籽的饱和脂肪酸含量为19.5% (m/m)外,饱和脂肪酸的含量很少(<17%)。尼日尔油与大豆油的相似度更高,而克拉姆油和油籽萝卜油的相似度更高。通过这种方式,可以通过提出的方法区分油样品中存在的不同脂肪酸,有助于实现研究目标,并在生物燃料生产等背景下做出更好的决策。

Comparative Study of Fatty Acid Composition in Crude Vegetable Oils from Species Cultivated in Mato Grosso do Sul, Brazil
Soybean is the main oilseed cultivated in the Middle-west region of Brazil, once geoclimatic conditions favor its cultivation and underexplored species such as crambe, oilseed radish, and niger too. These species can be alternatives to eliminate the conflict between food and energy production, so the study aimed to evaluate and compare the fatty acids content of soybean, crambe, oilseed radish and niger oils by gas chromatography with flame ionization detector using two quantification methods, followed by multivariate statistical analysis to determine the similarity between the selected species and to provide safe information for the best selection and application of these oilseeds. The oil content in crambe, oilseed radish and niger seeds were 44.7% (m/m), 42.45% (m/m) and 28.19% (m/m), respectively. The major fatty acid in niger and soybean oils was linoleic acid (66.9% and 52.07% m/m, respectively), in crambe and oilseed radish was erucic acid (65.29% and 33.54% m/m, respectively). In addition, for saturated fatty acids, the presence is minor (<17%), except for niger seeds with 19.5% (m/m). Niger oil has greater similarity with soybean oil, whereas crambe and oilseed radish oils are more similar to each other. In this way, it was possible to discriminate the different fatty acids present in the oil samples by the proposed method contributing to the objective of the study and enabling better decision-making in the context like biofuels production.

期刊介绍: Orbital: The Electronic Journal of Chemistry is a quarterly scientific journal published by the Institute of Chemistry of the Universidade Federal de Mato Grosso do Sul, Brazil. Original contributions (in English) are welcome, which focus on all areas of Chemistry and their interfaces with Pharmacy, Biology, and Physics. Neither authors nor readers have to pay fees. The journal has an editorial team of scientists drawn from regions throughout Brazil and world, ensuring high standards for the texts published. The following categories are available for contributions: 1. Full papers 2. Reviews 3. Papers on Education 4. History of Chemistry 5. Short communications 6. Technical notes 7. Letters to the Editor The Orbital journal also publishes a number of special issues in addition to the regular ones. The central objectives of Orbital are threefold: (i) to provide the general scientific community (at regional, Brazilian, and worldwide levels) with a formal channel for the communication and dissemination of the Chemistry-related literature output by publishing original papers based on solid research and by reporting contributions which further knowledge in the field; (ii) to provide the community with open, free access to the full content of the journal, and (iii) to constitute a valuable channel for the dissemination of Chemistry-related investigations.
