    Experimental Determination of the Qualitative Composition of Chladone Extracts of Bay Leaf
    (2019) Vladymir Potapov, Dmirtiy Billiy
    The features of the use of laurel leaf extracts in food production are considered. The characteristics of the main substances contained in the leaves of the Noble laurel are listed. The chemical composition of Noble laurel proves the prospect of using extracts in food production. The extraction and environmental advantages of extraction with liquefied gases were analyzed, traditional methods of extracting vegetable oil, as well as their comparative characteristics were given. The stages of the technological process of extraction of laurel oil using liquefied chladone are shown, the organoleptic characteristics of the final product are evaluated. In the process of chemical analysis of the refrigerant extract, it was determined that the use of the modern method of chladone extraction with liquefied gases allows extracting the extract with a significantly larger amount of aroma-forming substances. The obtained values of the number of aroma are compared with the indicators of aqueous-alcoholic extract, which exceed the latter several times. Studies of extracts by gas chromatography have been described, as a result of which more than 50 components have been identified, among which fatty acids and ether derivatives are of particular interest. It was revealed that the chladone extract of laurel leaves retains the color, smell and taste of the original plant materials. The results of gas chromatography were compared with literature data on the qualitative composition of bay leaf extracts obtained by microwave extraction and supercritical fluid extraction, as a result of which it was established that chladone extract of bay leaf has the same dominant compound 1,8-cineole. Of particular value are eugenol derivatives, which can act as antioxidant supplements in the treatment of cancer.
