What was bvo originally designed for

Hyperpolarized neurons are very difficult for other neurons to stimulate and this leads to the feeling of calmness or sedation. Plus, bromide can accumulate in our bodies. Back in the ss, overuse of bromide products led to appropriately named medical conditions. Our soda-pop drinking man showed many of the symptoms of bromism — but how? Brominated vegetable oil, called BVO for short, is made by adding bromine across the double bonds of certain fatty acids in vegetable oil, usually soybean oil.

Like plain vegetable oil, BVO does a good job of dissolving water-insoluble food flavour, fragrance and colouring agents, serving as a carrier for these agents in soft drinks, which are mostly water. Over time, gravity does its job and the emulsion breaks down, causing the oil and water to separate. If a plain vegetable oil is used, the oil fraction — which contains those all-important flavouring agents — would float to the top.

One way to control creaming is to add some denser oil, adjusting the density until it matches the aqueous fraction. It also does a great job of keeping citrus oils, plus other fragrance or flavour oils, just where they should be in a beverage — suspended. But is BVO safe as a food additive? On average, soft drinks manufacturers use about 8 parts per million — not quite enough to totally prevent creaming, though it slows it way down.

Our brominated man was no normal soda-pop drinker. Research shows that Americans drink about litres of soft drinks per year per capita. Lipid soluble additives that are much less water soluble than the flavor oils the vegetable oil, wood rosins or SAIB slow Ostwald ripening.

When the flavor oil diffuses out of a small droplet it makes the remaining oil more concentrated with respect to these other components. Concentrating a solution is opposed by the entropy of mixing which will slow and eventually stop Ostwald ripening.

A safer switch? BVO has seeped into Europe, mostly forbidden territory for this additive, according to an analysis of imported sodas presented at an international symposium on halogenated persistent organic pollutants in He said soda makers in North America could easily replace BVO with alternatives such as hydrocolloids — chemicals that are used in many sodas in Europe. Natural hydrocolloids form small droplets on water into which non-water soluble compounds can be stored and stabilized for as long as necessary.

They are almost exclusively natural products, Vetter said. Barnes, of the Dr. Pepper Snapple Group, said that BVO and hydrocolloids "do not provide the same functionality and cannot be substituted for one another. Vetter disagreed, saying that countries in Europe and elsewhere have used natural hydrocolloids for decades in the soda brands that rely on BVO in North America. With natural alternatives already in use in other countries, why not switch in North America too?

Wim Thielemans, a chemical engineer at the University of Nottingham in the United Kingdom, said since the alternatives are already used in Europe "their performance must be acceptable, if not comparable, to the U.
