Bioemulsans: microbial polymeric emulsifiers.
Bioemulsans are amphipathic proteins and/or polysaccharides that stabilize oil-in-water emulsions. Bioemulsans are produced by a wide diversity of microorganisms and have potential applications in the food, paper, paint, bioremediation, agriculture, detergent and cosmetics industries. The production of the RAG-1 emulsan has been studied in batch-fed fermentors via self-cycling fermentation and ...
متن کاملHydrocolloids as emulsifiers and emulsion stabilizers
We consider the essential molecular features of hydrocolloids having the ability to act as emulsifying agents and emulsion stabilizing agents. The criteria for effectiveness in protecting newly formed droplets against flocculation and coalescence are contrasted with the requirements to maintain long-term stability against aggregation, creaming and Ostwald ripening. To illustrate various aspects...
متن کاملSynthesis and Commercial Preparation of Food Emulsifiers
Food emulsifiers, more correctly referred to as surfactants, are molecules, which contain a nonpolar, and one or more polar regions. In general, nonpolar groups are aliphatic, alicyclic, or aromatic hydrocarbons. Polar functional groups contain heteroatoms such as oxygen, nitrogen, and sulfur. As shown in Fig. 2.1, the polar functionality makes the emulsifier anionic, cationic, amphoteric, or n...
متن کاملEffect of Food Emulsifiers on Aroma Release.
This study aimed to determine the influence of different emulsifiers or xanthan-emulsifier systems on the release of aroma compounds. Solid-phase microextraction (SPME) and GC-MS were used to study the effects of varying concentrations of xanthan gum, sucrose fatty acid ester, Tween 80 and soybean lecithin on the release of seven aroma compounds. The effects of the emulsifier systems supplement...
متن کاملA Conserved Tripeptide Sorts Proteins to Peroxisomes
The firefly luciferase protein contains a peroxisomal targeting signal at its extreme COOH terminus (Gould et al., 1987). Site-directed mutagenesis of the luciferase gene reveals that this peroxisomal targeting signal consists of the COOH-terminal three amino acids of the protein, serine-lysine-leucine. When this tripeptide is appended to the COOH terminus of a cytosolic protein (chloramphenico...
