Red Potato Pulp and Cherry Pomace for Pasta Enrichment: Health-Promoting Compounds, Physical Properties and Quality

Abstract

Cherry pomace and red potato pulp were examined as a source of nutritional and health-promoting compounds in pasta products, which could gain popularity among consumers. An attempt was made to obtain such pasta with the help of low-temperature extrusion (50 °C). The purpose of the study was to demonstrate which additive and in what quantity would have a more favorable effect on the nutritional, pro-health and physical quality of pasta. It was found that all pasta samples obtained with cherry pomace had a higher content of fat (10%), ash (3%), fiber (2 times) and polyphenols (22%), together with α tocopherols, than pasta with red potato pulp. Nonetheless, it had a lower water-binding capacity (20%) and higher optimum cooking time. Pasta with cherry pomace was characterized by a good taste and an attractive smell, so this additive should be recommended to obtain products with better nutritional and pro-health value and quality, especially at 30%.
