BACKGROUND/OBJECTIVES: To assess developments in the nutritional quality of food products in various food groups in France, an Observatory of Food Quality (Oqali) was created in 2008. To achieve its aims, Oqali built up a new database to describe each specific food item at the most detailed level, and also included economic parameters (market share and mean prices). The objective of this paper is to give a detailed analysis of the monitoring of the ready-to-eat breakfast cereals (RTEBCs) sector in order to show the benefits of the Oqali database.
SUBJECTS/METHODS: Analysis was limited to products with nutritional information on labels. Packaging was provided by manufacturers or retailers, or obtained by buying products in regular stores. Economic parameters were obtained from surveys on French food consumption and data from consumer purchase panels. The breakfast cereal sector was divided into 10 categories and 5 types of brand. Oqali has developed anonymous indicators to describe product characteristics for each category of RTEBC and each type of brand by cross-referencing nutritional values with economic data. Packaging-related data were also analysed. The major nutritional parameters studied were energy, protein, fat, saturated fat, carbohydrates, sugars, fibre and sodium. Analysis was performed on the basis of descriptive statistics, multivariate statistics and a Kruskal-Wallis test.
For the RTEBC, there is large variability in nutrient content throughout the sector, both within and between product categories. There is no systematic relation between brand type and nutritional quality within each product category, and the proportion of brand type within each product category is different. Nutritional labels, claims and pictograms are widespread on packages but vary according to the type of brand.
These findings form the basis for monitoring developments in the nutritional composition and packaging-related data for breakfast cereals in the future. The final objective is to expand the approach illustrated here to all food sectors progressively.
背景/目的：为了评估法国各种食品中食品质量的营养变化，2008 年成立了食品质量观察站（Oqali）。为了实现其目标，Oqali 建立了一个新的数据库，以最详细的水平描述每种特定的食品，并包括经济参数（市场份额和平均价格）。本文的目的是详细分析即食早餐麦片（RTEBC）部门的监测情况，以展示 Oqali 数据库的优势。
主体/方法：分析仅限于标签上有营养信息的产品。包装由制造商或零售商提供，或通过在普通商店购买产品获得。经济参数来自法国食品消费调查和消费者购买小组的数据。早餐麦片部门分为 10 个类别和 5 个品牌类型。Oqali 开发了匿名指标，通过将营养值与经济数据交叉参考，为每个 RTEBC 类别和每个品牌类型描述产品特征。还分析了与包装相关的数据。研究的主要营养参数是能量、蛋白质、脂肪、饱和脂肪、碳水化合物、糖、纤维和钠。分析基于描述性统计、多变量统计和克鲁斯卡尔-沃利斯检验。
对于 RTEBC，整个部门的营养成分含量存在很大的差异，无论是在产品类别内还是类别之间。在每个产品类别内，品牌类型与营养质量之间没有系统的关系，而且每个产品类别内的品牌类型比例也不同。营养标签、声称和象形图在包装上很常见，但根据品牌类型而有所不同。
这些发现为未来监测早餐麦片的营养成分和包装相关数据的发展奠定了基础。最终目标是逐步将这里所展示的方法扩展到所有食品部门。
