Abstract

Against the background of increasing attention to the environment, minimizing waste from the canning industry is becoming increasingly important. This also applies to by-products of pomegranate juice production - the peel (all solid parts of the pomegranate fruit, except seeds) and seeds, which account for about 60% by weight in pomegranates. However, this issue has been overlooked for a long time, since 10-20 years ago there were not so many pomegranate juice producers, and the competition for its sales markets was not as high as it is now. Activity in this area has revived somewhat after recent research, which revealed the multifaceted properties of this type of bio-waste. They showed that the peel and seeds of pomegranates are rich in several groups of substances that could become valuable food additives, and dietary fiber can be attributed to one of these groups. Obtaining dietary fiber preparations is associated with the need for appropriate processing of the feedstock, aimed at isolating the target group of substances from the rest of it.  This article focuses on some important aspects of the procedure for isolating the complex called “dietary fiber” from the rest of the pomegranate peel, described in the published works of some authors and the authors of this article. This is important, since the solution to this issue is currently in the New Product Development stage - a combination of research, engineering and design processes that are needed to create it in the best form and launch it to a certain limited market.
