Standardized language across different data systems through common codes, previously agreed worldwide, enables global comparability and facilitates clearer food identification. Designing a sampling plan for food component studies involves planning and fieldwork phases using methods like random, stratified, selective, or convenience sampling based on study goals and resources. Factors like geographical and seasonal variations, production methods, and cultivar differences are critical considerations for accurate representative analytical results. Ensuring high-quality documented analytical carotenoid data is crucial for understanding their impact on health. Data quality could be evaluated based on criteria such as food description, sampling plan, and analytical method procedure ensuring reliable results for advancing nutritional science and public health.engCarotenoidsFoodEx2LanguaLFoodOnIntakeHealthDietQuality CriteriaFood Data EvaluationComposição dos Alimentosbook part10.1007/978-1-0716-4570-3_12662-3518
