After a lot of testing VIVES managed to make a tasty and healthy yacón ice cream. This turned out to be a far greater challenge than originally thought. Objectives of the research are:
Yacón is a new emerging vegetable (root vegetable), with the advantage that it is rich in inulin, a prebiotic with health-giving properties (e.g. against diarrhoea). Inulin is a carbohydrate (fructo-oligosaccharides (FOS)), a collective name for sugar chains that are not metabolized by humans and so exhibit a low calorific value what is interesting to people with diabetics or obesity.
In addition, inulin can be used by its sweet taste as a sugar substitute and inulin also has fat emulsifying properties that results in less fat that is needed to make ice cream.
The yacón ice cream currently has both a fat and sugar reduction of around 80% over standard vanilla ice cream! With this result the yacón ice cream scores even better than diet ice cream!
Diet ice cream is often on the basis of Stevia and often gives an undesirable aftertaste. In addition to the inulin of the yacón an extra sugar substitute (around 10%) is added. VIVES tries currently several sugar substitutes.
VIVES is still working on the recipe of scoping the ice cream long-term. There are already market parties interested to launch this ice cream on the market in the future.
The peels and the rotten tubers can be used as a substrate for insect rearing
