Safety of tetrahydrocurcuminoids from turmeric (Curcuma longa L.) as a novel food pursuant to Regulation (EU) 2015/2283

Trends and current food safety regulations and policies for functional foods and beverages containing botanicals

Globally, the demand for functional foods and beverages has significantly increased due to socioeconomic changes, particularly in health consciousness to enhance their functionality. Functional ingredients derived from botanicals are widely used because of their phytochemical properties with health benefits. This study aims to (1) review the capabilities and challenges of botanical addition in functional foods, (2) review current policies and regulations for functional foods containing botanicals in the European Union (EU), Canada, Japan, the Republic of Korea, and Thailand, and (3) provide recommendations on effective food safety control measures for better consumer trust and trade facilitation. This critical review was analyzed from online publications and available guidelines, regulations, and control measures published by food industries and governments in the EU and the four selected countries. The result confirmed that potentialities of botanicals arise from numerous bioactive compounds with varieties of sources. However, the usage may potentially raise health risks through hazardous substances in different species or plant parts, contaminants from environments and uncontrolled processes. Inadequate knowledge of botanical formulation and the maximum limit for daily consumption may elevate health risks through food-drug interaction or adverse effect incidents. Current policies and regulations show that varieties of measures are implemented influencing both economic growth and consumer awareness. The novel finding is that countries that provide a comprehensive national food control system influence not only the growth of the functional food subsectors but also build trust in food safety among trade partners and consumers.

Study of the authentic composition of the novel green foods: Food colorants and coloring foods

The clean label approach is behind the development of the new concept, coloring food, in contrast to regulated food colorants, although few data are available regarding its composition. Consequently, twenty-six commercial green foods (including novel foods) have been analyzed to investigate the authentic composition behind the different labels. It has been identified by HPLC-ESI/APCI-hrTOF-MS2 the complete array of chlorophylls in the regulated green food colorants, several of them identified for the first time in foods. The coloring food alternative is based on mixing blue (such as spirulina) and yellow (such as safflower) hues. Our data suggest that in the analyzed samples, spirulina is water or solvent extracted before being added to the food. The obtained results showed for the first time, the authentic data on the chemical composition of the new green foods.
