Efficent use of antioxidants to preserve fruit juice

Abstract

In order to follow up spoilage of fruit juice: apple and orange juice, treated or non-treated with synthesis antioxidants and powder natural extracts, the samples have been analysed during production process and after storage for 5 days at a temperature of 50°C (ASLD method - accelerated shelf life determination), by determining the vitamin C content, the clarity and colour, and also the water activity. Previously, antioxidants activity was calculated for the synthesized compounds and powder natural extracts.
