The human gut is unable to digest the long fibre prebiotics so while they taste sweet, they are calorie free.
The human taste study used a panel of 10 experienced experts to test the sweetness of six customised prebiotic sweeteners derived from several high intensity sweeteners. All of the naturally sweet prebiotics are oligosaccharides, which are carbohydrates that have between three and 10 simple sugars linked together.
The customised oligosaccharides demonstrated sweetness of between 140-223 times the sweetness of an equivalent concentration of sugar. This means a far lower concentration of the oligosaccharides would be required to achieve the same level of sweetness as sugar.
The results revealed there was a large reduction in bitterness without any effect on sweetness. The prebiotic sweeteners were developed using OptiBiotix’s technology platform which generates prebiotic microbiome modulators, which then increase the growth, biological activity and health benefit in the human microbiome.
Reducing the sugar content of food and drink products is a key objective for the food industry, with governments worldwide urging food and beverage manufacturers to lessen sugar content in their products.
