Abstract

The objective of this work was to evaluate the reuse of sucrose syrup in pineapple (Ananas comosus) osmotic dehydration and the application of the spent solution in fruit dragee formulation. Osmotic dehydration trials were performed in five cycles (65 degrees Brix/45 degrees C/3 hours), directly reusing the osmotic solution, with only one intermediate reconditioning step. Variations in osmotic solution properties and in dehydration parameters were observed, as well as a low microbial load in the system. The spent solution was rich in vitamin C (30 mg 100 g(-1)). Pineapple dragee covered with red fruits and acai powders were obtained with the reconditioned spent solution used as an adhesion solution. The dragee presented high levels of vitamin C (176 mg 100 g(-1)), polyphenols (154 mg GAE 100(-1) g), carotenoids (220 mu g 100 g(-1)), and potassium (330 mg 100 g(-1)). The product showed good sensory acceptance and purchase intention. Reusing sucrose syrup is technically feasible during pineapple osmotic dehydration, as is the application of the spent solution as an ingredient in fruit dragee production. (AU)
