Physicochemical and sensory characteristics of gluten-free noodles added with chicken breast meat: a comparative study with wheat flour noodle

The rising health consciousness of consumers has resulted in multiple studies on the use of animal and vegetable proteins in gluten-free noodle production, but chicken breast meat (CBM) has not been the subject of such studies. Thus, we aimed to create protein-fortified gluten-free noodles using economical and nutritious CBM and compare their quality attributes with commonly used wheat flour noodles (WN). Among the CBM noodles (CN), CN with tapioca starch (CN-T) showed the highest sensory and textural similarity to WN. The color values of cooked noodles were not considerably different. The water absorption capacity and volume expansion ratio of CN-T were not significantly different from those of WN. In CNs, an ungelatinized microstructure was observed, and CN-T displayed well-formed structural bonds related to adhesiveness, similar to WN. The CN-T had a protein content about 2% higher than WN. This finding is informative for the development of gluten-free noodles using CBM.

Classification, quality characteristics, sensory perception and texture prediction of wooden breast myopathy in broilers from Argentina

The objective of this study was to characterize the wooden breast (WB) myopathy in the poultry industry, and establish degrees of severity by analyzing the composition and important characteristics of meat quality. 175 chickens from the COBB-500 commercial line were analyzed, and three WB categories were established: normal, moderate, and severe. The prevalence was: 4.00% severe, 46.29% moderate, and 49.71% normal, and it was affected by sex and weight. The WB characterization was carried out on 7 breasts of each WB degree. A decrease in protein and ashes, an increase in fat and loss of water by dripping, and color changes were observed as the degree of severity advanced. The texture was evaluated by instrumental, sensory, and image analysis techniques. Severe samples showed alterations in compression test, cohesiveness and juiciness, together with significant differences on the parameters, "contrast" and "energy". A characterization of WB myopathy was achieved for the first time in Argentina. The decline in meat quality could lead to industrial losses. Image analysis proved to be a promising technique for differentiating the severity of WB myopathy in raw chicken. Differences between raw and cooked samples were detected, thus both types of meat should be studied in detail.

Water properties and marinade uptake in broiler pectoralis major with the woody breast condition

To provide insight into the mechanisms by which the woody breast (WB) condition reduces marinade uptake, water properties of normal (NOR) and WB meat were investigated using TD-NMR. Broiler Pectoralis major was marinated with either water, 0.625% sodium tripolyphosphate, 5% NaCl, or 5% NaCl + 0.625% sodium tripolyphosphate (SP). Targeted final concentrations were 4% NaCl and 0.5% SP. WB reduced meat marinade uptake but did not affect relationships between marinade ingredients and water mobility. WB inhibited increases in extra-myofibrillar water mobility induced by marinade ingredients. Marination increased intra-myofibrillar water (Amp₂₁) regardless of marinade ingredients or muscle condition; however, WB resulted in reduced Amp₂₁. Additionally, NaCl- or phosphate-induced extra-myofibrillar water (Amp₂₂) gain in WB was greater than that in NOR. Our data suggest changes in both Amp₂₁ and Amp₂₂ are related to the difference in marinade uptake between NOR and WB meat marinated with NaCl-phosphate marinade.

Effect of ultrasound assisted collagen peptide of chicken cartilage on storage quality of chicken breast meat

This study investigated the effect of ultrasound assisted chicken cartilage collagen peptide (CP) treatment on the storage quality of chicken breast meat. There were five meat groups at 4 °C for 60 min as follows: untreatment (Control), immersing in deionized water (DW), ultrasound treatment in DW (UDW), immersing in CP (0.15 g/100 mL) solution and immersing in ultrasound combined with CP (UCP). The results showed that the drip and cooking loss of meat decreased significantly in UCP at4and -18 °Cwith the extension of storage time. A large amount of non-flowing water transformed into free water in the 4 °C for 5 d, and the smallest degree of water migration was observed at -18 °C in UCP. The texture parameters of UCP group were significantly improved, especially for decreased hardness and increased elasticity. Furthermore, there had no significant effect on the color of chicken breast.

Comparison of quality traits among breast meat affected by current muscle abnormalities

Over the past several decades, as a result of the increasing growth rate and body size of modern hybrid birds, poultry industry has been facing up the occurrence of many breast meat abnormalities, such as White Striping (WS), Wooden Breast (WB) and Spaghetti Meat (SM), whose incidence has recently reached alarming levels. Thus, the present study aimed at simultaneously investigating the implications of WS, WB and SM abnormalities on meat colour, pH, proximate composition, fatty acid profile, collagen, thermal properties as well as texture and water mobility, assessed on both superficial and deep section of Pectoralis major muscle. Overall, the occurrence of breast abnormalities is associated with a higher ultimate pH and a significant increase in moisture and fat level, coupled with a decrease in protein and ash content with WB showing the most detrimental effect. However, fatty acid profile resulted to be mildly modified only by WS. Moreover, WB fillets showed significantly higher (P < .001) collagen content and stromal protein denaturation enthalpy associated with an altered water distribution and mobility within the muscle tissue. On the contrary, SM samples displayed a lower (P < .001) collagen cross-linking and a softer texture after the cooking. Overall, these findings reveal that the occurrence of WB abnormality exerts a more profound and prominent effect on meat quality traits rather than the presence not only of WS, but also of SM.
