Therefore, the emulsifying capacity of peptides derived from the enzymatic hydrolysis of proteins depends on the protein source and the hydrolysis conditions, such as degree of hydrolysis (DH), type of enzyme and pH of the environment [26,27]. The degree of hydrolysis is defined as the percentage of total peptide bonds that are cleaved in the ...
The maximum volume of microbial suspension per hour that can be treated by the larger commercial machines is 4,500 liters for high-pressure homogenizers versus about 1,200 liters for bead mills. Even larger capacity high-pressure homogenizers are available but their efficiency in disrupting microbial cells has not been documented.

Food emulsions are classified as macroemulsions with droplet size of 0.2 to 50 µm. Emulsion represents a heterogeneous mixture of fat globules. Food emulsions can be of the oil in water (O/W) or water in oil (W/O) type. The difference between O/W and W/O emulsions is that an O/W emulsion commonly exhibits a creamy texture, while a W/O …

7.1 Introduction. An emulsion is a type of dispersion in which a liquid phase composed of small droplets or globules is distributed homogeneously throughout a liquid vehicle in which it is immiscible using an emulsifying agent. The liquid phase consisting of small droplets is referred to as the dispersed or internal phase, while the vehicle in ...
Emulsifying capacity and creaming stability were determined for various WPI and dWPI emulsions. The overrun of dWPI s was approximately 50% lower than WPI s at pH 3.4 and 6.8.
5.2.1 Emulsification of bio-oil. Emulsification includes the blending of bio-oil into another liquid fuel such as diesel or biodiesel to improve its chemical and fuel properties. The pyrolysis-derived bio-oil emulsified in the ratio of 1:4, 1:2, and 1:3 with diesel fuel become a more stable product compared to that of raw pyrolysis oil.
Figure 1. Oil-in-water emulsion interface. This molecular arrangement promotes emulsion formation and stability in two ways. First, the internal phase droplets, because they are surrounded by the electrically charged hydrophilic ends of the emulsifier molecules, are inhibited from merging to form larger droplets.

The emulsifying activity index (EAI) and emulsifying stability index (ESI) of SPP emulsions subjected to the different HHP levels are shown in Fig. 4.9A and Bpared to the control (0.1 MPa) emulsions, the HHP treatments resulted in an EAI increase in the SPP emulsions at the pH values 3, 7, and 8. When the pressure was increased to 200 MPa, …
2.1. The role of the interfacial properties on the emulsification. Emulsification is associated to an important increase of the interfacial area ΔA which requires, from a thermodynamic point of view, a work on the system proportional to the interfacial tension, γ, that is W = γ∆A.

Thus, these results suggested that the emulsifying capacity of composite colloidal particles was higher as compared with that of pure SPI because of their contact angle values approaching to 90°. In addition, when the ratio of BCNs/SPI increased to 9:25, the contact angle of composite colloidal particles reduced to 58.60°, which could be ...

SUMMARY— A method was developed to objectively measure the emulsifying capacity (ECJ of meat and fish protein extracts by electrical resistance. The method of Swift et al. (1967) was modified to deliver oil at a constinuous rate at the point of blender agitation, thus forming an emulsion for testing the validity of the electrical resistance method. This …
This is because the meats of older animals have less salt soluble proteins but their emulsifying capacity is more efficient. To produce a finer texture, the mixture can be passed through an emulsifying mill. As this operation is accompanied by a rise in temperature of 2.5–4.5°C, the initial temperature of the mixture prior to the emulsifying ...

The emulsifying capacity of a protein (or a protein aggregate) can be characterized by measuring the emulsion droplet size at a particular protein concentration: the smaller the droplet, the better the protein aggregate as an emulsifier (Euston & Hirst, 1999). Differences in emulsifying capacity can generally be attributed to the surface ...
