    This trial investigated how different salts and antioxidants influence cholesterol oxides, microbial profiles, physicochemical properties and organoleptic characteristics of low-fat chicken sausages (CS). CS were formulated with either 2 % NaCl, CS-1; 2 % NaCl +0.02 % butylated hydrox­ yanisole (BHA), CS-2; 1 % NaCl + 1 % KCl + 0.25 % onionskin extract (OSE), CS-3; 1 % NaCl + 1 % KCl + 0.5 % OSE, CS-4; 1 % NaCl + 1 % K3C6H5O7 + 0.25 % OSE, CS-5 or 1 % NaCl + 1 % K3C6H5O7 + 0.5 % OSE, CS-6, cooked, and refrigerated for 45 d. The Na content in CS-1 and CS-2 (1185 ± 21 mg/100 g) was greater than that in the other CS (640 ± 18 mg/100 g). The 19-hy­ droxy cholesterol, 7α-hydroxycholesterol, 25-hydroxycholesterol, 5,6β-epoxycholesterol, 7β- hydroxycholesterol and carbonyl content were greater in CS-1 than in the other sausages. The OSE-treated CS group had lower levels of 7β-hydroxycholesterol and 7α-hydroxycholesterol than did the CS-2 group. CS-1 and CS-2 were lighter than the other CS. Malondialdehyde, pH, chemical composition, textural profile, microbial counts, cook loss and sensorial quality were unaffected by additives. The partial replacement of NaCl with KCl and K3C6H5O7, along with the addition of BHA and OSE, decreased the Na and cholesterol oxide contents without affecting the organoleptic qualities of low-fat CS.

    The effect of rice husk flour (RHF) supplementation on the physicochemical properties, oxidative stability, and sensory attributes of beef sausages was examined. Beef sausages were formulated with either 0 % RHF + 15 % wheat flour (WF), RHF-0; 5 % RHF + 10 % WF, RHF-5; 10 % RHF + 5 % WF, RHF-10, or 15 % RHF + 0 % WF, RHF-15, and cooked at 200 ◦C for 20 min. RHF supplementation significantly increased dietary fiber while decreasing moisture content (P < 0.05). Beef sausages with RHF had lower L*, a*, TBARS, carbonyl content, hardness, chewiness, and gumminess, and a higher pH (P < 0.05). RHF-10 and RHF-15 sausages exhibited greater cook loss compared to other formulations (P < 0.05). The levels of 7-ketocholesterol decreased with increasing RHF levels, while 7α-hydroxycholesterol and 7-hydroperoxycholesterol were higher in RHF-0 and RHF-10 sausages compared to RHF-5 and RHF-15 sausages (P < 0.05). In addition, RHF improved the taste, juiciness, appearance, and overall acceptance of beef sausages. These findings suggest that RHF can be a valuable ingredient in beef sausages by increasing fiber content, reducing oxidative degradation, and maintaining sensory quality despite some moisture loss.
