Gut flora with persimmons plums and blueberries-powder strengths?
If food with a powder, blueberries and persimmons plums are treated-by-products, seems to be the subsequent consumption a positive effect on the intestinal flora have an impact, which in turn has numerous positive health effects.
In the production of fruit and vegetables extremely a lot of to fall by-products and residues, which can be used in a meaningful way. A current investigation with the participation of the University of Valencia shows that a powder has such by-products of blueberries, and persimmons plums a positive effect on the intestinal microbiota, if it is added to foods. The results were published in the English journal “Journal of Agricultural and Food Chemistry”.
By-products of food to good use
The world population continues to increase. A diet of all these people in a sustainable way to ensure this is not a simple task. Here, the use of previously used could be by-products useful to provide on the one hand, people with healthy food and to reduce waste products. The researchers attempted such by-products of fruit and vegetables in nutritious food ingredients and dietary supplements convert.
The research group found out, so that waste of blueberries and persimmon can be processed into powders, which are particularly rich in antioxidants and a positive effect on the intestinal microbiota act.
Important antioxidants from fruits and vegetables
In recent years, powder from fruits and vegetables have become increasingly popular, beneficial Compounds such as polyphenols and carotenoids, food add. In many cases, these health-promoting Compounds, however, similar or even higher concentrations in by-products than in other Parts of the fruit or vegetables, report the researchers in a press release from the American Chemical Society.
What was studied?
The Team tried prunes powder of Persimmon and blueberry waste. Then, it was examined how the digestive system could affect the release of antioxidants and other bioactive Compounds. They have also tried, in addition, to determine the effects of the digested powder on the growth of intestinal bacteria.
The production process influenced the release of antioxidants
The researchers won the powder from the shells and Flowers of the persimmon, as well as the solids, in the manufacture of blueberry juice to stay back. The type of the powder, the drying method, the fiber content and type of fibers in certain of the subsequent release of antioxidants, according to the research team. For example, were preserved during freeze-drying, the more anthocyanins.
Increase of healthy bacteria found
The Team conducted various studies, in which the before and after the Fermentation the bacteria were sequenced. The fruit powder led to an increase in several types of beneficial bacteria. Some types of bacteria increased, however, by one of the powder better than the other, report the researchers.
Content of carotenoids and anthocyanins in food increase
The results of the investigation indicate that powder from waste of persimmons plums and blueberries, of certain foods could be added to increase the content of carotenoids and anthocyanins. This could have a positive impact on human health, explain the researchers. (as)
