There is a growing interest in the revalorization of co-products from the food industry. Co-products from tiger
nuts (Cyperus esculentus) milk production are a suitable fibre source. “Chorizo” is the most popular dry-cured
meat product in Spain. The aim of this work was to study the effect of the tiger nut fibre addition (0, 5, and
7.5%) on the quality (composition, physicochemical, and sensorial properties) and safety (oxidation and microbial
quality) of a Spanish dry-cured sausage, during the 28 days of its dry-curing process. Tiger nut fibre (TNF)
addition decreased fat and increased moisture content. The addition of TNF significantly increased (p b 0.05)
the total dietary fibre content of “Chorizo”. Lightness (L*), yellowness (b*) and redness index (a*/b*)were significantly
(p b 0.05) affected by the fibre content. The addition of 5% and 7.5% TNF to chorizo provided rich fibre and
a healthier product. Although there were slight changes in the physicochemical properties, its quality (traditional
characteristics) and its safety remained.
