| Abstract | Hydroxypropylation with propylene oxide followed by esterification with octenyl succinic anhydride (OSA) was used to produce modified potato starch derivatives suitable for the encapsulation of essential oils. Caraway essential oil (EO) was encapsulated by spray-drying into enzymatically hydrolyzed dual/single modified and native starches. The EO microencapsulation efficiency in different modified starches, the retention of volatile aroma compounds, the emulsion particle size and the microstructure of the spray-dried encapsulated powdered products, as well as the compositional aroma changes taking place during the processing and storage for up to 8 months have been estimated. The increase of OSA content from 0.97 to 2.52% in the P-native structure and from 0.91% to 2.66% in P-HP resulted in the significant increase in the encapsulating capacity, evaluated as a percentage of the total EO retained, from 61.6 to 88.0% and 73.8% to 84.0%, respectively. However, the compositional changes of the microencapsulated caraway EO constituents were not remarkable. Additionally, the effect of pure and encapsulated caraway EO products on the oxidative stability of commercial rapeseed oil and mayonnaise was evaluated using the instrumental Oxipres method and it was shown that they were more effective in emulsion type products by the up to 1.8-fold increase in the oxidative stability of mayonnaise. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
