Introduction. The addition of phosphates improves the emulsifying and gelling properties of meat proteins as well as overall product quality. The effect of phosphate addition on the properties of low-fat chicken sausages containing wheat bran was studied in this article. Materials and methods. Cooking loss, emulsification stability, water distribution, texture and sensory characteristics of wheat bran chicken sausage added with different amounts of complex phosphate were determined. Results and discussion. The positive influence of phosphate addition on technological and textual properties of meat products is known, however taking into account consumer’s acceptability, determination of phosphate content in sausages ensuring their high quality but not but not exceeding this value is needed. Low–fat chicken sausages with increased dietary fiber content due to inclusion in the sausage formulation of wheat bran were used as the object of the study. Comparative characteristics of wheat bran chicken sausage added with different amounts of complex phosphate, namely, 1.0, 1.5 or 2.0 g to 400 g of ground chicken meat were determined. It was shown that the minimum cooking water and fat losses were observed when addition of 1.5 g of complex phosphate was used. Thus, addition of 1.5 g of complex phosphate to 400 g of ground chicken meat ensured better retaining of water and fat, lowest cooking loss and highest emulsifying stability than in cases when 1.0 or 2.0 g of complex phosphate were added. At the same time, the results showed that the sausage containing 1.5 g phosphate per 400 g of ground chicken had the highest hardness, elasticity and chewiness, and the highest overall acceptability score of sensory evaluation, but the difference was not significant (P>0.05). Addition of 1.5 g phosphate per 400 g of ground chicken reduced the fluidity of free water in the sausage, and thus enhanced the water-retaining ability of chicken sausage. In addition, the results of the pseudo-color map showed that the semi-bound water of the S2 and S3 treatment groups increased significantly. Conclusions. Addition of complex phosphate, 0.2 %, in formulation of low-fat wheat bran chicken sausages decreases cooking, moisture and fat losses, and improves the texture and sensory properties of the final product.

Chicken sausage is one of the very popular meat products. In order to change the nutritional composition of chicken sausage and increase the content of dietary fiber, we add bran, but it affects the textural properties of chicken sausage. Pork rind is rich in collagen and is a natural and safe food gel. Pork rind content affects the cooking loss, color, TPA, moisture distribution and sensory evaluation results of cooked sausage products. In this study, six different pigskin content treatment experiments were set up: 0%, 5%, 10%, 15%, 20%, and 25%. This research shows that adding pork rind can reduce cooking loss during the sausage heating process. As more pork rind was added, the L* and b* values ofminced meat and chicken sausage gradually increased, while the a* value gradually decreased. The chewiness of the sausages in the test group was significantly reduced (p0.05), and the hardness value increased significantly (p This study improves the gel properties of bran chicken sausage, provides scientific data support for the application of pork rind in chicken sausage, improving the application value of pork rind.

Poultry sausage is a low-fat, protein-friendly product, and the research on poultry sausage has gradually become a hot field of meat product research. The baking process can promote the decomposition of protein and fat, and the Maillard reaction occurs, thereby increasing the color of the sausage and improving the flavor of the sausage. Baking time affects cooking loss, color, pH, TPA, moisture distribution and sensory evaluation results of cooked sausage products, therefore, the baking process is very important. In this study, four baking treatment experiments of 40,60,80 and 100min were set up, the baking temperature was 60°С. The 60min treatment group had the smallest brightness value L, the highest redness value a, and the best color. The water content of the 40min treatment group was the highest, followed by the 80min treatment group, and the pH value of the other 80min treatment group was also the lowest. In terms of TPA and water distribution, the hardness value of the 60min treatment group was the highest, and the relaxation times (T2) corresponding to hydrated water, fixed water and free water were 0.1‑9.3 ms, 10‑91 ms, and 175‑900 ms, respectively, and the 80 min treatment group The group with the most semi-bound water worked best. In terms of sensory evaluation, the color, flavor, texture, and overall acceptability of the 60‑80 min treatment groups were not significantly different. The best evaluation result was the 100 min treatment group, followed by the 60 and 80 treatment groups. Based on the above research results of sausage quality, the optimal baking time of sausage in this study is 60‑80 min. This research can provide product quality data and technical support for the development of duck and pork compound sausages.
