Riboflavin is yellow or orange-yellow in
colour and in addition to being used as a food colouring it is
also used to fortify some foods.
It can be found in such foods as baby foods, breakfast cereals,
sauces, processed cheese, fruit drinks and vitamin-enriched milk
products as well as being widely used in vitamin supplements.
Also known as vitamin B2 occurs naturally
in milk, cheese, leafy green vegetables, liver and yeast but exposure
to light will destroy the Riboflavin in these natural sources.
In processed foods it is very likely to be Genetically Modified
as it can be produced synthetically using genetically modified
Bacillus subtilis, altered to both increase the bacteria production
of riboflavin and to introduce an antibiotic (ampicillin) resistance
It is an easily absorbed, water-soluble micronutrient
with a key role in maintaining human health. Like the other B
vitamins, it supports energy production by aiding in the metabolising
of fats, carbohydrates and proteins. Vitamin B2 is also required
for red blood cell formation and respiration, antibody production,
and for regulating human growth and reproduction. It is essential
for healthy skin, nails, hair growth and general good health,
including regulating thyroid activity. Any excess is excreted
in the urine but as the human body does not store Riboflavin it
is thought deficiency is common.
Riboflavin also helps in the prevention or
treatment of many types of eye disorders, including some cases
of cataracts. It may assist bloodshot, itching or burning eyes
and abnormal sensitivity to light.
It is difficult to incorporate Riboflavin into many liquid products
as it has poor solubility. Hence the requirement for E101a Riboflavin-5'-phosphate,
a more expensive but more soluble form of Riboflavin.
Consists mainly of the monosodium salt of the 5'-monophosphate
ester of riboflavin dihydrate obtained from chemical action on
E101 Riboflavin. It is rapidly turned to free riboflavin after
Found in many foods for babies and young children
as well as jams, milk products and sweets and sugar products.
Likely to be Genetically Modified.
