1. Charakterystyka żywności / składnika

The food constituent that is the subject of the health claims is vitamin A (including β-carotene as a precursor of vitamin A) which is a well recognised nutrient. It is measurable in foods by established methods.
The term vitamin A describes a group of lipid soluble compounds related metabolically to all-trans-retinol. In the diet, vitamin A is found in products of animal origin as retinyl esters, mainly retinyl palmitate. Other esters (oleate, stearate, myristate), and retinol contribute to the dietary vitamin A intake. Some carotenoids (α- and β-carotenes, β-cryptoxanthine) can be cleaved into retinol, via an enzymatic process in the small intestine. Retinoic acids are considered as the molecular species responsible for all the functions attributed to vitamin A, with the exception of vision, where only retinal is the active agent (SCF, 2002). Recent studies reported that the conversion efficiency of dietary β-carotene is in the range of 10 to 28:1 by weight. As a result the US Food and Nutrition Board revised the estimated efficiency conversion factor for the conversion of dietary β-carotene to vitamin A from 6:1 by weight to 12:1 by weight. However, this conversion ratio should be regarded as temporary and could change as more data become available (Tang, 2010).
Different forms of vitamin A are authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/20066 and Annex II of Directive 2002/46/EC7). This evaluation applies to vitamin A naturally present in foods and those forms authorised for addition to foods and for use in food supplements (Annex II of the Regulation (EC) No 1925/2006 and Annex II of Directive 2002/46/EC).
The Panel considers that the food constituent, vitamin A (including β-carotene as a precursor of vitamin A), which is the subject of the health claims is sufficiently characterised.

The claimed effects are “le beta-carotène est transformé par l'organisme en vitamine A qui joue un rôle dans la vision” and “vision”. The Panel assumes that the target population is the general population.
A claim on vitamin A and maintenance of normal vision has already been assessed with a favourable outcome (EFSA Panel on Dietetic Products Nutrition and Allergies (NDA), 2009).
