Objective: This study was performed to evaluate the quality characteristics of reducednitrite boiled pork sausages (BPSs) with paprika oleoresin solution (POS) to compensate for the reduced sodium nitrite (NaNO2).
Methods: POS was prepared by diluting paprika oleoresin with sunflower seed oil at a ratio of 1:20. BPSs were subjected to four different treatments: reference (REF), BPS added with 150 ppm NaNO2; control (CTL), BPS added with 37.5 ppm NaNO2; treatment 1 (TRT1), BPS added with 37.5 ppm NaNO2 and 0.1% POS; treatment 2 (TRT2), BPS added with 75 ppm NaNO2 and 0.1% POS).
Results: The pH values of CTL were lower than those of other treatments. The a* values of TRT1 were higher than those of CTL, and those of REF were lower than those of TRT1 and TRT2. The b* values of TRT1 and TRT2 were higher than those of REF and CTL. The total plate counts of CTL were the highest among all treatments, and Enterobacteriaceae counts of CTL and TRT1 on the 14th day were higher than those of REF and TRT2.
Conclusion: The combination of 75 ppm NaNO2 and 0.1% POS to BPS during storage had an antimicrobial effect similar to that of adding 150 ppm NaNO2. Thus, POS can be used to reduce the use of NaNO2 in meat products.

This study was conducted to evaluate the effect of sodium nitrite (NaNO, 100-200 ppm), sodium erythorbate (SE, 0-547 ppm), sodium tripolyphosphate (STPP, 0-0.5 %), and sodium chloride (NaCl, 2-3 %) on growth of C. perfringens using a solid growth medium and to develop a growth/no-growth boundary (critical control surface, or CCS) to prevent its growth in cooked cured meat under the optimal temperature condition.

This study aimed to evaluate a pomegranate peel extract (PPE), selected for its level of phytochemical compounds and antioxidant activities, as a nitrite substitute in dry sausages, as well as its effect on lipid and protein oxidative changes and instrumental colour during the drying period (28 days). Of the extraction solvents screened, water: acetone 3:7 (v/v) was the most effective extraction solvent, yielding extracts with the highest content of phenolic compounds, flavonoids and condensed tannins and antioxidant activities (ABTS, DPPH and FRAP). Four batches of dry sausages were produced with different incoming amounts of sodium nitrite (NaNO) and PPE: 1) 150 ppm NaNO; 2) 0 ppm NaNO; 3) 0 ppm NaNO + 1% PPE (v/w) and 4) 0 ppm NaNO + 2% PPE (v/w).

digestions of dry-cured sausages formulated with four different rates of added sodium nitrite and sodium nitrate (NaNO / NaNO, in ppm: 0/0; 80/80; 120/120; 0/200) were performed with a dynamic gastrointestinal digester (DIDGI®). The chemical reactivity of the potentially toxic nitroso-compounds (NOCs), oxidation reactions products and different iron types were evaluated over time. No nitrite nor nitrate dose effect was observed on NOCs' chemical reactivity.
