Title

Bioactive components from potato juice as pâté additive and effect of its form on pâté quality

Abstract

The objective of the research study was to assess the effect of potato juice, a source of bioactive compounds with evidenced health promoting properties, and used in the pâté recipe, on the texture, microstructure and sensory properties of the products obtained. The potato juice added had two forms: a fresh form and a spray-dried form. The analyses performed on a semi-industrial scale confirmed that the use of appropriate technology to manufacture pâté with bioactive components added to it made it possible to produce a sensory attractive, health promoting product that was highly appreciated by consumers. It was also shown that, regardless of its form, the potato juice additive significantly affected the change in the texture of pâtés and caused their hardness, spreadability, and viscosity to increase and their adhesion to decrease. However, the form in which potato juice was added to pâtés affected the degree of dispersion of fat in pâtés and the consumer acceptance of the products. Pâté enriched with pray-dried potato juice caused the dispersion of fat droplets to increase and those fat droplets also became more equally distributed in the enriched pâté structure. In the case the potato juice was added in the form of fresh juice, no statistically significant changes in the fat dispersion parameters analysed were found compared to pâté with no additive. The evaluation of the sensory attractiveness of pâté proved that pâté enriched with the fresh potato juice was rated very highly (in terms of colour, consistency, and tastiness) similar to the pâté without enriching additives. On the other hand, in the case of pâté enriched with the spray-dried potato juice, its acceptance by consumers was slightly lower.
