Argan oil: Occurrence,composition and impact on human health

Edible argan oil is traditionally prepared by Berber women who manually crunch the roasted kernels of Argania spinosa fruits. Unroasted kernels furnish a cosmetic‐grade oil. Argan groves are currently shrinking due to unfavorable conditions. To stop this trend, a program aimed at increasing the argan tree economical value is in progress in Morocco. Its concept is that the natives will preserve argan trees only if the major part of the wealth resulting from the argan grove production directly benefits them. Because of its high dietary value, argan oil has appeared as the best derivative to rapidly satisfy such assumption. Consequently, year after year, cooperatives have been implanted to produce argan oil of high quality on a large scale. The delicate hazelnut taste of argan oil, combined with its high level in unsaturated fatty acids, has allowed its swift commercial success and, nowadays, argan oil of standardized quality is marketed worldwide. Moroccan farmers are now beginning to plant argan trees, confirming the full success of this ambitious program. This review summarizes the methods used to prepare argan oil, its composition, the strategies available to certify argan oil quality, and finally the impact of argan oil on human health.     

Phenolic acid content and sensory properties of two Spanish monovarietal virgin olive oils

In recent years, phenolic acids have received considerable attention as they are essential to olive oil quality and nutritional properties. This study aims to validate a rapid and sensitive method based on ultra‐performance liquid chromatography/time‐of‐flight mass spectrometry (UPLC–TOF‐MS) for analyzing the phenolic acid content of olive oil and assessing its impact on virgin olive oil (VOO) sensory attributes. Once this method was validated, we used it to evaluate the phenolic acid composition of several Spanish monovarietal virgin olive oils in relation to nine different olive ripening stages. The results obtained confirm that the methodology developed in this study is valid for extracting and analyzing phenolic acids from VOO. The phenolic acid content of the virgin olive oils sampled was proven to be influenced by the type of cultivar and olive harvest date. Therefore, phenolic acids might be used as potential markers for olive oil cultivar or ripening stage. Finally, the data obtained indicate that the sensory properties of VOO may be differently affected by its phenolic acid content depending on the type of cultivar. Practical applications: The method validated in the present study – based on UPLC‐TOF‐MS – allows experts to assess the phenolic acid content of different VOO cultivars (varieties). This application will probably be very useful to the olive oil industry. The reason is that our study revealed that phenolic acids have an impact on the sensory quality of VOO, which is essential to consumer preferences and choice. In addition, there are phenolic acids that are only found in a particular variety of olive oil obtained from fruits at a specific ripening stage. Consequently, phenolic acids could be used as potential markers for olive oil variety and harvest time.     

海洋溢油化学指纹分析鉴定方法探讨

石油资源分布不均推动石油勘探和运输规模不断扩大,溢油事故日益增多,包括井喷,船舶漏油等,带来环境损害评估等问题。油指纹分析鉴定通过研究油品风化周期,推断溢油对环境的影响时间,通过生物毒性实验判断对环境影响程度。为事故调查处理提供科学依据,包括缩小调查对象范围,确定溢油来源种类。针对当前溢油鉴定中的问题进行研究,表明油品混合可能存在化学变化,扩大混合前油品特征比值差异,正构烷烃特征比值与萜烷类特征比值相同,可能为不同油品,说明多采集油品特征信息是溢油鉴定的重要基础。

Almost complete dehulling of high oil sunflower seed

An almost complete dehulling (hull residue lower than 3%) of sunflower seeds, before oil extraction, reduces to a minimum both the transfer of pigments from hulls to the flour and the content of fiber in the finished product. In this paper some results of our work on the dehulling of high-oil seeds with an air-jet impact huller are presented. The effectiveness of dehulling has been evaluated as a function of characteristics of the seed (variety, moisture and so forth) and of operative parameters (impact velocity, etc.). The optical analysis of the impact of the seeds on the target was made optical analysis of the impact of the seeds on the target was made by means of high-speed cinematography (about 8000 frames/sec) to have a better view of the phenomenon and to measure the parameters of energy involved. The use of proper seed monentum, which is a function of the characteristic of the seed, can allow selective hull breaking with minimum kernel breakage. Almost complete hull-free kernels from high-oil sunflower seeds were obtained by means of a continuous dehuller-separator pilot plant.
