Qualitative Characteristics of Selected Liquid Fruit Products Available on the Polish Market

The current study aimed to assess the quality of selected liquid food products made from apple juice and available on the domestic market. The study determined the extract content, pH and density of twenty products, i.e., juices, nectars, soft drinks and smoothies from different producers. The study shows that the apple juice-based liquid products tested differ in terms of quality. The analyses also show that there is a greater variation in the apple juice-based liquid products tested in terms of extract content, to a lesser extent in terms of acidity, whereas in terms of density, it is small but statistically significant. The highest extract content, density and pH values were noted for the smoothies and apple juices, whereas the lowest values were noted for soft fruit drinks and nectars.
