Vegetable-milk-based yogurt-like structure: Rheological properties influenced by gluten-free carob seed flour

There is a constant increase in the attention being paid to food quality and the effects of food on human health among consumers. Vegetable milk is among the foods whose consumption worldwide has increased because, when compared to animal-derived milk, it offers numerous benefits for human health. The aim of this research work was to use vegetable milk to obtain yogurt-like products enriched with different concentrations of carob seed flour, which has a double function: to modify, and thus perfect, the rheological characteristics of vegetable-milk-based yogurt-like samples and to increase their nutritional value. The rheological parameters of the obtained samples were studied both in static and dynamic conditions, confirming that carob seed flour, especially at the highest used concentrations (0.75%; 1%), allows one to obtain products characterized by a good stability and suitable rheological characteristics. The obtained yogurt-like products may also be consumed by celiac subjects, since carob seed flour is a gluten-free flour, and allow celiac consumers to combine a gluten-free diet with a diet free of animal derivatives. Furthermore, the addition of carob flour allows one to obtain a tasty product thanks to the sweet taste of the carob seed flour.
