Evaluation of chicken nugget properties using spent hen meat added with milk fat and potato mash at different levels.

ABSTRACT: This study was aimed to develop chicken nuggets using spent hen meat (SHM) added with milk fat (MF) and potato mash (PM) at different levels. Four different spent hen nuggets (SHNs) i.e. T1 (75% SHM with 5% MF), T2 (70% SHM with 8% MF and 2% PM), T3 (65% SHM with 11% MF and 4% PM), and T4 (60% SHM with 14% MF and 6% PM) were formulated and compared with the control, using broiler chicken meat without MF and PM. The control, T1, and T2 were not significantly different with respect to protein and fat contents. The emulsion stability (92.2%), frying yield (84.1%), hardness (19.2 N) and chewiness (11.4 N) of T2 were similar to the control. The incorporation of MF and PM resulted in increased taste and flavor scores for SHN. The overall acceptability score was same for the control and T2. The conjugated dienes and thiobarbituric acid-reactive substance results showed that the addition of MF at 8 to 10% did not have an effect on the oxidative stability of SHN during storage. MF-incorporated SHN may be a regular chicken nugget for all consumers due to improved texture and sensory quality with similar fat content to the control.

Project description:BackgroundDietary fat is important for energy provision and immune function of lactating sows and their progeny. However, knowledge on the impact of fat on mammary transcription of lipogenic genes, de novo fat synthesis, and milk fatty acid (FA) output is sparse in sows. This study aimed to evaluate impacts of dietary fat levels and FA composition on these traits in sows. Forty second-parity sows (Danish Landrace × Yorkshire) were assigned to 1 of 5 dietary treatments from d 108 of gestation until weaning (d 28 of lactation): low-fat control diet (3% added animal fat); or 1 of 4 high-fat diets with 8% added fat: coconut oil (CO), fish oil (FO), sunflower oil (SO), or 4% octanoic acid plus 4% FO (OFO). Three approaches were taken to estimate de novo milk fat synthesis from glucose and body fat.ResultsDaily intake of FA was lowest in low-fat sows within fat levels (P < 0.01) and in OFO and FO sows within high-fat diets (P < 0.01). Daily milk outputs of fat, FA, energy, and FA-derived carbon reflected to a large extent the intake of those. On average, estimates for de novo fat synthesis were 82 or 194 g/d from glucose according to method 1 or 2 and 255 g de novo + mobilized FA/d according to method 3. The low-fat diet increased mammary FAS expression (P < 0.05) and de novo fat synthesis (method 1; P = 0.13) within fat levels. The OFO diet increased de novo fat synthesis (method 1; P < 0.05) and numerically upregulated mammary FAS expression compared to the other high-fat diets. Across diets, a daily intake of 440 g digestible FA minimized milk fat originating from glucose and mobilized body fat.ConclusionsSows fed diets with low-fat or octanoic acid, through upregulating FAS expression, increased mammary de novo fat synthesis whereas the milk FA output remained low in sows fed the low-fat diet or high-fat OFO or FO diets, indicating that dietary FA intake, dietary fat level, and body fat mobilization in concert determine de novo fat synthesis, amount and profiles of FA in milk.
