卷烟材料标准体系的建立与探讨

卷烟材料是卷烟产品不可缺少的主要组成部分。卷烟材料标准是为了提高和保证卷烟材料产品质量而制定的,没有标准就谈不上质量。卷烟材料标准体系是烟草行业标准总体系的组成部分,是将一定范围内的标准,按其内在联系形成的科学的有机整体。本文对我国烟草行业标准化及卷烟材料的发展进程作了简要地回顾,客观地分析了烟草行业标准化及卷烟材料标准实施所取得的成绩和存在的不足,提出了建立卷烟材料标准体系的必要性和应遵循的基本原则,探讨了建立卷烟材料标准体系的框架结构。      

Correlation study between standard plate count and flow cytometry for determination of raw milk total bacterial count

Milk samples were collected in the dry season ( n =  155) and in the rainy season ( n =  68) to establish a correlation between electronic flow cytometry and standard plate count for the determination of total bacterial count of raw milk. Results were expressed in individual bacterial count (ibc) and colony forming unit (cfu) for electronic flow cytometry (Bactocount) and standard plate count, respectively. The accuracy of Bactocount, denoted by the residual standard deviation ( s ( y,x )), was 0.309 log cfu/mL. The predictive interval of estimated values was broad and it is suggested that total bacterial count should be expressed in ibc without transformation to cfu.

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.
