Project summary

The project idea-the study of pectic-OS structure and functional relationship and its association with polyphenolic compounds accompanies as in origin plant materials would definitely provide a pathway (mechanism) for its pharmacological activities and application in the healthy food. Recently, interest in oligosaccharides has increased not only because of properties that include sweetening ability and fat replacement, but also because of resistance to digestion in the upper gastrointestinal tract and fermentation in the large bowel. These compounds are easily incorporated into processed foods and hold much promise as functional ingredients in nutraceutical products. Fruit pomace also is a rich source of antioxidants which have been shown to exhibit health-promoting effects. These compounds shall be employed as functional food ingredients and as natural antioxidants.
The goal of this project is to explore the possibility of using agricultural post-harvest by-products in Tajikistan for the purpose of health-care for local residents. We propose to use OS, which is found in apple pomace, sugar beet pulp, sunflower heads, grape cake and ephemeroids plants growing in Tajikistan, to construct an advanced healthy materials (AHM) to colon site microflora from pathogenic species. This technology can be applied for the treatment of chronic diseases and for prevention of infectious diseases.
The project is important as far as it concerned the creation of the functional food. Furthermore the dried fruits have been used in Tajik herbal medicines for the treatment of chronic heart diseases and hypertension. The pharmacologically activity polysaccharides in fruits mainly have the nature of pectic polysaccharides.
The new technologies and products generated through this research will be transferred to stakeholders and industry by means of direct communication, patents, publications in scientific journals; presentations in workshops and conferences. Project also attempts to wide collaborative investigations on commercialization of pectin-polyphenol advanced materials in the food and pharmaceutical markets of the both countries.
Project has incorporated two Institutes, Chemistry and Plant Physiology and Genetics of Tajikistan Academy of Sciences. These Institutes staff has wide research experience both in polymer chemistry and biochemistry and genetics. Laboratories equipped with necessary instrument (listed before) and facilities, which can provide best income for project. Moreover these institutes include 5 Doctor of Sciences, 6 PhD scientists, 4 post-graduated student directly will contribute to related subject.


The International Science and Technology Center (ISTC) is an intergovernmental organization connecting scientists from Kazakhstan, Armenia, Tajikistan, Kyrgyzstan, and Georgia with their peers and research organizations in the EU, Japan, Republic of Korea, Norway and the United States.


ISTC facilitates international science projects and assists the global scientific and business community to source and engage with CIS and Georgian institutes that develop or possess an excellence of scientific know-how.
