The Tryptophan in Food (Scotland) Regulations 1990
These Regulations, which apply to Scotland only, prohibit the addition of Tryptophan (an amino acid) to food intended for human consumption, and its consequent sale or supply (regulation 3(1) and (2)), subject to an exception for those who require the food on medical grounds (regulation 3(4)). These Regulations also prohibit the exposure for sale of food intended for human consumption containing added tryptophan (regulation 3(3)). Contravention of or failure to comply with these prohibitions is made an offence and provision is made for district and islands councils to enforce the Regulations (regulation 5). The Regulations also make provision for the application of specified procedural provisions of the Food and Drugs (Scotland) Act 1956 to these Regulations (regulation 6).
