Abstract:
En este trabajo se aplicó harina obtenida a partir de higo chumbo (Opuntia -Ficus), a un lácteo de tipo yogurt a fin de evaluar el efecto de la adición de harinas obtenidas de la piel y la pulpa del higo chumbo, Opuntia ficus-indica, sobre las propiedades fisicoquímicas y sensoriales de un yogur el...  Ver más
In this study we have researched the effect of prickly pear (Opuntia ficus-indica) on sheep milk yogurts. Flour made from the pulp and the peel of the fruit was added to the yogurts, to measure physiochemical and sensorial properties. We obtained three formulations with different flours of the different parts of the fruit. The incorporation of the prickly pear flour modified some yogurt characteristics. At a physiochemical level, a reduction in the fermentation time - pH 4,6 -, and a change in colour, with a predominance of red, yellow and darker tones, were observed. In the sensory evaluation, the yogurt with peel flour stood out by it scent and texture, while the control yogurt was evaluated positively by its color and taste, quite opposite to the sample with prickly pear pulp. The prickly pear consumption is more common in South America than in Spain; however, its treatment by dehydration, and milling, transforms it into a flour with great technological advantages. This flour offers functions of fat substitution, and quality, texture and viscosity enhancement, thanks to its richness in fiber, furthermore, it may also have prebiotics functions. At an environmental level, the elaboration of flour from fruit subproducts can promote the circular economy, giving new value to diverse products and minimizing food waste.
