The physicochemical properties of cholesterol reduced egg yolk powder produced by removal of P-cyclodextrin inclusion complex and its application in mayonnaise / Fauziah Che In

Association of eggs to high cholesterol level in body is greatly known. Liquid egg yolk is also difficult to transport due to their bulkiness, fragility and highly perishable. Egg yolk powder with reduced cholesterol content would be beneficial and nutritious to consume. Therefore, the aim of this s...

Liquid egg yolk is also difficult to transport due to their bulkiness, fragility and highly perishable. Egg yolk powder with reduced cholesterol content would be beneficial and nutritious to consume. Therefore, the aim of this study is to reduce egg yolk cholesterol by using P-cyclodextrin at different concentrations and the quality of cholesterol reduced egg yolk powder was analysed for mayonnaise production, p-cyclodextrin concentration used were at a range of 0-15 mM. At 15 mM P-cyclodextrin, egg yolk powder was successfully produced with 98.12% of cholesterol reduction. However, no significant reduction (p>0.05) was noticed in the lipid content range from 55±13.23 to 48±0.10 g/lOOgm. The process of cholesterol removal caused significant reduction (p<0.05) in protein range from 38.86±0.26 to 35.43±0.16 g/lOOgm and in saturated fatty acids range from 154.7±6.09 to 61.62±0.54 mg/g, monounsaturated fatty acids range from 240.23±6.75 to 90.09±0.53 mg/g and polyunsaturated fatty acids range from 28.97±0.28 to 20.74±0.002 mg/g. Cholesterol-reduced egg yolk powder and its inclusion complex produced at 15 mM were characterised using Differential Scanning Calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and X-Ray Diffraction (XRD) followed with its application in mayonnaise. Results obtained indicate that cholesterol: P-cyclodextrin inclusion complex behave differently when compared with egg yolk cholesterol: Pcyclodextrin inclusion complex which showed that compounds other than cholesterol might be encapsulated in egg yolk cholesterol inclusion complex. Mayonnaise made using cholesterol-reduced egg yolk were further analysed. Emulsion capacity and emulsion stability were analysed, and the results showed no significant difference (p>0.05) between egg yolk powder-without cholesterol removal (emulsion capacity: 58.43±4.73%, emulsion stability: 58.52±1.78%) and cholesterol reduced egg yolk powder (emulsion capacity: 59.82±3.41%, emulsion stability: 56.06±2.07%). However, viscosity of mayonnaise prepared from cholesterol-reduced egg yolk powder (8000±16.0 cP) was differ significantly (p<0.05) from egg yolk powderwithout cholesterol removal (4768±16.0 cP). Egg yolk powder-without cholesterol removal was differed significantly (p<0.05) from cholesterol-reduced egg yolk powder in term of lightness (L), redness (a), yellowness (b), chroma (C) and hue angle (h°) values. The results obtained for sensory characteristics showed no significant difference (p>0.05) in term of overall acceptability between mayonnaise made using egg yolk powder-without cholesterol removal and cholesterol-reduced egg yolk powder with 6.30±1.09 and 6.23±1.14, respectively. Therefore, p-CD can be used to produce cholesterol-reduced egg yolk powder and healthier food products. 2018 Thesis https://ir.uitm.edu.my/id/eprint/67507/ https://ir.uitm.edu.my/id/eprint/67507/2/67507.pdf text en public masters Universiti Teknologi MARA (UiTM) Faculty of Applied Sciences
