Resumen :
Actualmente, la explotación del azafrán (Crocus sativus L.) en su forma de especia (estigmas desecados) genera una alta producción de subproductos florales (mayoritariamente tépalos) considerados desechos. Sin embargo, esta biomasa presenta un potencial interés bioactivo. Distintas formulaciones de...  Ver más
Nowadays, the saffron (Crocus sativus L.) exploitation in its spice form (dried stigmata) results in a high production of floral by-products (mostly of tepals) which are considered as waste. Nevertheless, this biomass presents a potential bioactive interest. Different formulations of wheat flour and spelt flour bread have been enriched with dried saffron tepals at 0; 2.5; 5 and 10 % w/w based on flour used. The main aim of this study was the valorization of saffron floral by-products through their use as functional ingredient in traditional bread recipes and to study their effects on the physicochemical properties such as pH, acidity, ºBrix, ash, texture and color as well as their chemical composition regarding the content of organic acids, soluble sugars and minerals. The results have shown the enrichment of breads modified the mineral levels and the organic acids and soluble sugars profile. In addition, the textural properties were also affected. Regarding the color, significant differences compared with the control bread were found in both the crumb and the crust. Therefore, the valorization of saffron floral by-products could lead to the environmental impact minimization, taking advantage of an unexploited biomass, in addition to obtaining new functional foods. Thus, saffron flowers could be considered as a suitable and sustainable ingredient for developing new products.
