Resumen
En el presente estudio se buscó evaluar la capacidad prebiótica del biopolímero Bilac® en condiciones in vitro, determinando la capacidad de algunas bacterias probióticas, como Bifidobacterium y Lactobacillus, de utilizar este biopolímero como fuente de carbono.
Se comprobó que en un uso conjunto entre probióticos y prebióticos es posible que la viabilidad de estas bacterias se mantenga alta en función del tiempo, para su uso en bebidas y alimentos.
Además, el estudio contempló un componente in vivo, en el cual se realizó un estudio clínico en humanos en donde se proporcionó en la dieta de las personas dosis diarias del biopolímero. Los resultados de estos ensayos permitieron concluir que, al consumir este biopolímero en galletas y una bebida láctea, aumenta la microbiota intestinal benéfica, y mantiene o disminuye levemente los coliformes.
Abstract
Certain chronic non communicable diseases, and gastrointestinal diseases can be prevented and
treated with the consumption of functional foods such as probiotics and prebiotics. Previous
studies both in vitro and in vivo in animals and humans show the beneficial effect that gives the
guest the daily consumption of these foods. Prebiotics include selectively fermentable soluble
fibers by the colonic microbiota, prevents intestinal discomfort such as constipation, so its
recommended consumption.
In Colombia certain types of diarrhea and gastrointestinal diseases in children are cause of
mortality. These diseases also affect adults and the elderly, as significant changes occur in the
intestinal flora towards a potentially harmful composition. Thus, we have increased the number of
studies on prebiotics and probiotics to evaluate the modification of the colonic microbiota towards
a favorable this beneficial physiological effects on the host composition.
The Bilac® biopolymer obtained at the Institute of Biotechnology of the National University of
Colombia presents important for use as prebiotic properties, as it is high in soluble fiber, it is an
alpha - glucan, α 2-6 linked a glucooligosaccharide. It has been previously reported to have
prebiotic effects glucoligosaccharide because they are non-digestible carbohydrates in the upper
gastrointestinal tract, reaching the colon intact where they are fermented by beneficial intestinal
microbiota.
In the present study aimed to evaluate the ability prebiotic Bilac® biopolymer under in vitro by
determining the capacity of some probiotic bacteria, such as Bifidobacterium and Lactobacillus,
using this biopolymer as a source of carbon.
It was found that in a joint between probiotics and prebiotics use it is possible that the viability of
the bacteria is kept high in terms of time, for use in beverages and foods.
In addition, the study included an in vivo component, in which a clinical study in humans in which
it was provided in the diet of people daily dose of the biopolymer.
The results of these tests led to the conclusion that this biopolymer consuming cookies and milk
drink, increases beneficial intestinal microbiota, and maintained or slightly decreased coliforms.
