Physicochemical, rheological, and sensory properties of low-fat ice cream designed by double emulsions

2017-09-01
This research was conducted to evaluate the applicability and effectiveness of using double emulsions to reduce fat content in ice cream. Polyglycerol poliricinoleate (PGPR)-lecithin blend and guar gum (GG) or guar gum-gum tragacanth (GGGT) blend were used as emulsifier/stabilizer in the formulations. Ice cream samples prepared by double emulsion method and by conventional method were compared in terms of rheological properties, overrun, melt-down resistance, and sensory properties. It was possible to reduce fat content of ice cream to 2.8% by means of double emulsion method without affecting ice cream quality adversely. Using GGGT blends in double emulsion formulation provided about 6% increase in overrun values, 13% decrease in rate of melting, and 20% increase in overall acceptability in sensory analysis as compared to the samples prepared by GG. Practical applications: The result of this research can be used in production of low fat ice cream. There have been many attempts to reduce fat content of ice cream by using fat replacers or components imitating fat. However, the major problem of using fat replacers is low sensory quality of reduced fat ice cream. In this study, double emulsion method was used for reducing the fat content of ice cream. It was possible to reduce fat content of ice cream to 2.8% by means of double emulsion method was possible without affecting ice cream quality adversely. Double emulsion as a new technique to form ice cream with reduced fat content without changing quality characteristics as compared to regular fat content ice cream.

Rheological and Microscopic Properties of Fat Blends with Similar Solid Fat Content but Different Trans Composition
Mert, Behiç; Sahin, Kubra; Tekin, Aziz (2013-01-01)
In this study, two different groups of fat samples were prepared in a way that samples of each group had different trans fatty acid (TFA) composition but similar solid fat content (SFC). Samples of the first group (named group A) had TFA between 0.0 and 56.23 %, while the samples of the second group (group B) contained trans isomers ranging from 0.0 to 44.4 %. A polarized microscope was used to monitor the differences between the samples in terms of crystal size and crystal number during isothermal crystall...
Rheology, particle-size distribution, and stability of low-fat mayonnaise produced via double emulsions
YILDIRIM, Merve; Şümnü, Servet Gülüm; Şahin, Serpil (2016-12-01)
In this study, the effects of the double emulsification method on the rheological properties, particle size, and stability of low-fat mayonnaise were studied. Different water-phase-to-oil ratios (2:8 and 4:6) of primary emulsions and different stabilizer types (sodium caseinate, xanthan gum, and lecithin-whey protein concentrate) were used to produce double-emulsified mayonnaise. As a control sample, mayonnaise was prepared conventionally. Sodium caseinate was found to be the most efficient stabilizer. In t...
Usage of multiple emulsions to design low fat ice cream
Tekin, Ezgi; Şahin, Serpil; Şümnü, Servet Gülüm; Department of Food Engineering (2015)
The primary objective of this thesis was to design similarly perceived low fat ice cream with regular fat ice cream by using multiple emulsions. Thus, it was aimed to prepare multiple emulsion formulations by using food grade stabilizers and emulsifiers and to reduce the amount of fat in ice cream considerably. With the use of polyglyserol poliricinoleate (PGPR) and PGPR-lecithin blend as emulsifier in the primary phase and different gums such as guar gum (GG), locust bean gum (LBG) and gum tragacanth (GT) ...
Investigation of amino acid modifications derived from lipid oxidation in foods
Karademir, Yeşi; Öztop, Halil Mecit; Department of Food Engineering (2019)
This study aimed to investigate lipid derived amino acid modifications in foods. When the revealed carbonyl pool resulted from the repeated use of frying oils and high absorption rates of the oil during frying are taken into consideration, deep-fat fried foods have a significant potential to investigate this type of reactions. In the first part, effect of heating time of the frying oil on amino acid modifications in potato chips and model doughs was investigated. 2,4-decadienal, total free amino acid, decad...
Influence of fat content and emulsifier type on the rheological properties of cake batter
Sakiyan, O; Şümnü, Servet Gülüm; Şahin, Serpil; Bayram, Göknur (2004-11-01)
The effects of fat content and emulsifier type on the rheological properties of cake batter have been investigated by using a parallel-plate rheometer. The apparent viscosity of cake batter with five different fat concentrations (0, 12.5, 25, 37.5, and 50%) and two types of emulsifier, namely Purawave and Lecigran, was studied as a function of the shear rate. In addition, the time dependency of different cake formulations was investigated. It was found that cake batter with different fat concentrations and ...
