Improving the Biotechnology of Pomegranate Botanical Extracts, Taking into Account the Need to Deepen the Processing of Raw Materials

摘要

Background and Objectives: The POMx and Pomanox extract technologies have been developed and used in the production by Pom Wonderful and Probeltibio companies. The production of pomegranate extracts was studied due to their beneficial effects on human health. The purpose of this study was to make better use of the functionality of Pomanox extract technology and to combine the extraction processes of both groups of polyphenols in one technology. Materials and Methods: POMx polyphenols were isolated by means of enzymatic water treatment of pomegranate juice by-products at temperature of 37-71°C. Pomanox technology is designed for enzymatic water treatment of whole pomegranate fruits, while its function is mainly to extract and use only the juice polyphenols at temperature of 4-30°C. After its implementation solid residue left behind which can be used for the preparation of POMx polyphenols. Experiments were conducted with grinding and enzymatic water extraction of fruits of the Azerbaijan pomegranate variety in the framework of the modes of industrially applied technologies. Results: It was found that the treatment of the solid residue at 71°C makes it possible to extract 32% more polyphenols in the extract than in a single extraction at 20°C. Conclusion: It is advisable to combine the processes of extraction of polyphenols of juice and peel in one technology which was not originally part of the function of this technology.
