Extracting gas from beans

BBC:

A method of creating super-nutritious but flatulence-free beans has been developed by scientists.

Beans are a cheap and key source of nutrition especially in the developing world, but many people are thought to be put off by anti-social side-effects.

A Venezuelan team says fermenting beans with certain friendly bacteria can cut the amount of wind-causing compounds, and boost beans' nutritional value.

Flatulence is caused by bacteria that live in the large intestine breaking down parts of food - such as soluble fibre - that have not been digested higher in the gut

Beans, such as the black bean commonly eaten across Central and Southern America and tested by the team, contain many of these compounds.

Researchers from the Simon Bolivar University in Caracas found that by boosting the natural fermentation process by adding a particular type of bacteria , called Lactobacillus casei (L casei), the amount of these indigestible wind-causing compounds were reduced.

Soluble fibre was reduced by two thirds and the amount of raffinose, another flatulence-causing substance, by 88.6%.

There is a much easier way of avoiding gas from beans. After the beans have soaked overnight pour out the water in which they soaked and wash the beans in fresh water. Then cook them in fresh water. It works.
