1. Charakterystyka żywności / składnika
The food constituents that are the subjects of the health claims are “silicon”, “silicon (as stabilised oligomeric orthosilicic acid (OSA))”, “choline-stabilised orthosilicic acid (ch-OSA)”, “Mineral- wasser/Kieselsäure (Silizium)”, “silica/silicious earth”, and “monométhylsilanetriol”.
From the references and conditions of use provided in relation to the health claims considered in this opinion, the Panel assumes that the food constituent under evaluation is silicon.
Silicon is authorised for addition to foods (Annex I of Regulation (EC) No 1925/20066 and Annex I of Directive 2002/46/EC7). This evaluation applies to silicon naturally present in foods and added to foods.
Silicon occurs naturally in foods as silicon dioxide (silica, SiO2) and silicates, and may also be added to foods as an anti-caking and anti-foaming agent in the form of silica, silicates and dimethylpolysiloxane. Silicate-containing antacids have been widely used for a number of decades.
Orthosilicic acid [Si(OH)4] or mono-silicic acid is a water soluble form of silicon. A saturated solution contains 0.1 % silicic acid. Silicic acid can also exist as an oligomer and as polysilicic acid (EFSA, 2004). Oligomeric silica (oligomeric orthosilicic acid) is formed as a meta-stable intermediate in the progressive polymerisation of silicic acid in saturated solutions. Monomethylsilanetriol, also called organic silicon (CH3-Si-(OH)3), and choline-stabilised orthosilicic acid (ch-OSA) are usually added to food supplements as a source of silicon (EFSA, 2009a, 2009b).
The Panel considers that the food constituent, silicon, which is the subject of the health claims, is sufficiently characterised.
2.3. Tworzenie bariery ochronnej na błonie śluzowej żołądka (ID 345)
The claimed effect is “gut health”. The Panel assumes that the target population is the general population.
From the clarifications provided by Member States, the Panel assumes that the claimed effect refers to forming a protective coat on the mucous membrane of the stomach.
The Panel considers that forming a protective coat on the mucous membrane of the stomach is not a beneficial physiological effect per se, but needs to be linked to a beneficial physiological or clinical outcome. The Panel notes that no evidence has been provided to indicate the context in which the claimed effect could be considered to be a beneficial physiological effect.
The Panel concludes that a cause and effect relationship has not been established between the consumption of silicon and a beneficial physiological effect related to forming a protective coat on the mucous membrane of the stomach.
2.4. Neutralizacja kwasu żołądkowego (ID 345)
The claimed effect is “gut health”. The Panel assumes that the target population is the general population.
From the clarifications provided by Member States, the Panel assumes that the claimed effect refers to the neutralisation of gastric acid.
The Panel considers that the evidence provided does not establish that the neutralisation of gastric acid is a beneficial physiological effect for the general population.
The Panel concludes that a cause and effect relationship has not been established between the consumption of silicon and a beneficial physiological effect for the general population related to the neutralisation of gastric acid.
