| Abstract | The aim of this study was to obtain a beverage with a high content of bioactive compounds. Therefore, a mixture of orange juice and milk was prepared. The effect of high-pressure processing (HPP), four different pressures (100, 200, 300, and 400 MPa), four treatment times for each pressure (120, 300, 420, and 540 s) on antioxidant compounds, and quality parameters was studied. The effects of HPP treatment were compared with those of thermal treatment (90 °C for 15, 21 s and 98 °C for 15, 21 s). Ascorbic acid retention in the orange juice–milk beverage was higher than 91% in all cases after HPP. There was a significant increase (p < 0.05) in phenolic compounds at 100 MPa/420 s, however at 400 MPa/540 s, it was observed a non-significant decrease. Total carotenoid content was significantly higher in all samples treated by HPP when treatment time was 420 and 540 s. Color changes increased when pressure and treatment times were higher, with the highest difference appearing at 400 MPa/540 s, but HPP had a smaller effect on total color changes than thermal processing. A 5-log reduction of Lactobacillus plantarum CECT 220 was obtained in the orange juice–milk beverage after HPP (200 MPa, 300 s), and this was compared with treatment at 90 °C (15 s), the heat treatment most effective at preserving ascorbic acid. |

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.
