硒作为油脂抗氧化剂的功用探讨

硒作为人体的一种必需微量元素，其生化功能是多方面的。而其中最重要的是硒的抗氧化性，是在七十年代才引起人们的注意，本文就硒在油脂中的抗氧化机理、硒作为油脂抗氧化剂的功用、硒在油脂领域的开发与应用作一探讨。     

Elaboration of Four Olive Oil Certified Reference Materials: InterOleo-CRM 2006 Certification Study

The study for the elaboration and certification of four olive oil reference materials covering all the physical–chemical characteristics, defined in Commission Regulation (EC) 1989/2003, is reported herein. The different steps of the process, preparation of reference materials, homogeneity and stability studies, and characterization study have been carried out for 14 laboratories from five European countries. The certificate of analysis for these certified reference materials (CRMs) provide assigned values for concentrations of more than 50 parameters or characteristics of olive oils in compliance with the European legislation about the labeling of food products. The certified values and its corresponding uncertainties were obtained applying robust statistics to the raw data provided by the laboratories taking part in the interlaboratory study. The certificate is valid for a maximum period of 18 months from the elaboration date. These four CRMs are intended for use as a primary material for quality control and for validation of analytical methods for measurements in authentication and adulteration problems of olive oils.

Oil and fatty acid distribution in different circles of sunflower head

Prevailing temperature at anthesis influences pollen health, fertilisation, seed filling, oil and fatty acid accumulation in different circles of sunflower head. Field experiments were conducted, during 2007 and 2008, at Pir Mehr Ali Shah, Arid Agriculture University, Rawalpindi, Pakistan, to document oil and fatty acid distributions in different circles of sunflower head. Hybrid S-278 was planted in randomised complete block design with a two factors factorial experiment, with four replications. At maturity, heads were divided into three equal circles (outer, middle and central); thereafter, oil and fatty acid distributions were separately determined in each circle. Oil and fatty acid concentrations in three circles differed significantly. The outer circle accumulated high oil and oleic contents which decreased to a minimum in the central circle; however, linoleic acid consistently increased, from outer to central circle, during both the years.

基于RAGA的PPE模型评价油页岩矿坑积水水质的研究

通过构造投影指标函数进行优化设计,建立基于实数编码的加速遗传算法的投影寻踪综合评价模型对油页岩露天矿坑积水水质进行评价.结果表明,该水质评价模型的相关系数为0.9999,对于油页岩矿坑积水水质评价精度较高,分析可知,评价水样多数为V类水,水质情况较差.进一步研究发现,RAGA-PPE模型对水质的评价是有一定的局限性的,评价水质指标超过最大指标标准过多,会导致评价模型精度下降.
