Based on the first version of the TABULA™ dataset, we provide a descriptive analysis of the composition of <em>n</em> = 6500 pre-packaged branded food and beverages marketed in Spain between January 2022 and November 2023. Information was collected from the package labelling of food and beverage products of manufacturer and distributor brands available through major retailer online shopping platforms. Products were categorized as defined in the World Health Organization 2023 nutrient profile model for the European Region. Analysis was performed for nutrients of mandatory declaration. For most categories, median content of the nutrients targeted for reformulation (namely sugars, salt, and saturated fats) was below the high-content thresholds defined by the Spanish Agency for Food Safety and Nutrition (AESAN). Due to their concurrent high contents of sugar and saturated fats as per the AESAN thresholds, “chocolate and sugar confectionery, energy bars, sweet toppings and desserts” and “edible ices” emerged as categories with a less favourable nutritional profile. We conclude that it is essential to monitor the nutritional quality and consumption of marketed food products to ensure the success of reformulation policies aimed at improving public health. The dynamic nature of food markets, characterized by frequent product introductions and discontinuations, highlights the need for branded food composition databases like TABULA™, which are helpful tools for monitoring product reformulation.</div></div>","PeriodicalId":15867,"journal":{"name":"Journal of Food Composition and Analysis","volume":"141 ","pages":"Article 107347"},"PeriodicalIF":4.0,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143394537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A high-throughput fluorescent aptasensor based on magnetic beads (MBs) attached to the aptamer (Apt) and rolling circle amplification (RCA) technology conjugated to thioflavin T (ThT) was developed for the detection of AFB1. Using the encoded circular DNA template for the RCA reaction, long single-stranded DNA containing a large number of G-quadruplexes sequences was obtained. A significant enhancement of ThT fluorescence intensity is achieved through the intercalation of a large amount of ThT into G-quadruplexes, which substantially improves the sensitivity of the aptasensor. In addition, the aptasensor uses ThT as a label-free fluorescent signal probe, which saves preparation cost, and achieves high-throughput magnetic separation and rapid detection with the help of a 96-well plate and microplate reader.
