BIOLOGICAL ACTIVITY OF SELECTED FRUIT AND VEGETABLE POMACES
Journal Title: Żywność. Nauka. Technologia. Jakość - Year 2012, Vol 19, Issue 4
Abstract
The objective of the study was to determine the content of selected components with biological potential in apple, grape, red beet, and carrot pomaces. In the samples investigated determined were: content of polyphenolic compounds and their antioxidant activity, content of sugars, and contents of dietary fibre and pectines. It was shown that the extracts obtained from the grape pomace were characterized by the highest antioxidant potential among all the samples analyzed. A relatively high antioxidant potential was also found in the apple pomace. The content of polyphenols in fruit waste was approximately 5 time higher than in the beet and carrot pomaces. Although the carrot pomace contains a low content of dry matter, it is still is a good source of β-carotene. The results obtained also prove that the beet, grape, and apple pomaces constitute a rich source of fibre. The content levels of pectines in the pomaces analyzed were similar. Only the waste of apples contained almost twice as much pectines as other pomaces
