Meat products reformulation is very complicated since the “charcuterie” is more than a technology. The addition of new ingredients is not an easy task; therefore, preliminary assays are carried out to determine their feasibility. Oleogels are “new ingredients” used to mimic fats and/or modify the fatty acids profile. To evaluate the chia oleogel (COG) feasibility in Frankfurt-type cooked sausages (FTCS) processing, several physical and physicochemical parameters, CIELAB color space, 2-Thiobarbituric acid reactive substances (TBARS), moisture, fat, pH, water activity (Aw), and residual nitrite level (RNL), were determined. In a traditional FTCS formula, the COG was used to replace pork back fat (substitution level 0%, 25%, 50%, and 75%). In FTCS, RNL were not detected in COG samples. The 75% substitution with COG increased moisture content. COG addition increased pH. For Aw, COG addition decreased their values in FTCS. The 50% and 75% of COG substitution increased TBA values. FTCS fat content for COG-added samples showed values between 22.35 and 23.85 (g fat/100 g). Thus, the use of chia oleogels is feasible in an industrial process and can be a good source to reduce nitrite residual level. |
