| Abstract Some foods constituents are subject to change during thermal and/or industrial processing. In the fruit processing industry, guava pulp is used during guava off season to obtain guava paste, produced with the addition of sugar and citric acid, subjected to various thermal processes. This study evaluated the effect of industrial processing to obtain guava paste on the content of ascorbic acid, total carotenoids, total phenolic and total flavonoid present in guava ‘Paluma’ cv. The results showed that there was an increase of antioxidants in guava pulp (15% ascorbic acid, 59% total carotenoids, 8% total phenolics and 54.5% total flavonoids), probably due to their increased concentration as a result of water loss during processing. There was... |
