As flavoring and natural preservatives are used in oil extracts or hydrolat aromatic plants, typical of the Crimea: rosemary, celery, dill, Basil and others.

"Oil extracts are created from dried plant materials, which we shred with the addition of a small amount of ethanol, which promotes the release medium polar compounds. Then, in the ratio of 1:10 added vegetable oil which we use in obtaining the mayonnaise, mix all in a special extractor, defend and filtered product", - quotes the press service of the University Elena Nozhko.

According to her, another technology is the use hydrolat aromatic plants, for which scientists use the green parts, roots and seed mass.

"We put the dry raw material in the flask, fill with water, plug the refrigerator back. During the first 15-20 minutes is distilled water fraction, which is the oily and combination – scented water. It contains large amounts of essential oils in a colloidal state, and there is a high concentration of biologically active substances, which partially serve as preservatives and can replace artificially produced phenolic compounds. And oil extracts and hydrolates contain valuable chemical compounds, giving the product taste and flavor. While the oil extract is introduced at the stage of oil flow, and wild raspberries – at the stage of preparation of mayonnaise pasta," said Elena Nozhko.

In the composition of the resulting mayonnaise product contains refined vegetable oil or blended vegetable oils with a balanced fatty acid composition, egg powder, gum guar and xanthan, and water. Its shelf life is one month. According to scientists, for longer storage it is necessary to introduce artificial preservatives.

"The cold method of producing mayonnaise sauce allows to keep all useful properties of the components of aromatic plants, so our product is positioned as a functional "Clean label" that is intended for a healthy diet. We contemplated getting our sauces in the HoReCa system. Here you can easily make production of small batches of product in a large range, that is, for any taste", - said Elena Nozhko.

Product analysis in compliance with GOST spent in Scientific research Institute of agriculture of Crimea. On the developed technology for production of mayonnaise and mayonnaise sauce scientists of the Crimean Federal University has obtained patents.
