Scientists figured out how to make wine and cheese with weed
Scientists of the South Ural state University (SUSU) discovered that the extract of common weeds — Bidens pilosa is a promising source of enzymes for the food industry. According to the authors obtained a series of substances may be available herbal alternative to expensive enzymes required in winemaking and cheesemaking. The study is published in the journal International Journal of Scientific and Technology.
Research South Ural state University scientists showed that an extract from the pulp of the leaves of Bidens pilose (Bidens pilosa L.) accelerates the cleavage of peptide bonds of protein, making it suitable for the production of various biologically active substances, in particular of the tyrosine part of proteins of all living organisms and was first isolated from cheese in 1846.
"There is an extensive tradition of using a series of hairy drugs. Due to the prevalence of its use, in our opinion, extremely profitable in the wine industry and dairies, where the succession could be an effective alternative food enzymes" — said the head of the Department "Food biotechnology" SUSU Irina Potoroka.
In experiments researchers SUSU it was proved that the fresh leaves are weedy herbaceous plants have high protease activity in acidic buffer pH 4 (8,2567 × 10-7 mm / mg / min) compared to the alkaline buffer pH 10 (5,15 × 10-7 mm / mg / min) at 30 degrees Celsius.
According to scientists, they were able to determine the optimal conditions of enzymatic activity of the leaf extract of a succession, allowing you to adapt it for use in various technological processes.
Irina Potoroka believes that it is necessary to continue the study of a succession of hairy to find out what part of the plant (roots, stem, flowers) has the highest protease activity, because held in SUSU, the study focused only on the fresh leaves.
The next stage of the work, the research team intends to study the mechanism of encapsulation, transportation and release of a succession of hairy in the biological environment to enhance the efficiency of the processes of fermentation.
Bidens pilosa is widely distributed in the world as a weed, introduced from America. In Russia, where Bidens pilosa L. quarantine refers to weeds that are prohibited to import, a plant discovered in the far East.
