1, sodium stearoyl lactate/calcium (ssl/csl)
It has the function of strengthening tendons and keeping fresh. On the one hand, it strongly interacts with protein to form gluten protein complex, which makes the gluten network more detailed and elastic, improves the gas retention of yeast fermented dough and increases the volume of baked bread;
On the other hand, it interacts with amylose to form insoluble complex, thus inhibiting the aging of amylose and keeping the freshness of baked bread. Ssl/csl can improve the softness of bread while increasing its volume, but its excellent effect will be weakened when it is compounded with other emulsifiers.
2. diacetyl tartaric acid monoglyceride
It can have a strong interaction with protein, improve the air-holding property of fermented dough, and thus increase the volume and elasticity of bread, especially when preparing soft flour. If only from the perspective of increasing bread volume, datem has the best effect among many emulsifiers, and it is also an ideal way to replace potassium bromate.
3. Sucrose fatty acid ester
Sucrose fatty acid ester is the most widely used bread quality improver, which can improve the crispness of bread, improve the viscosity of starch paste, the volume and honeycomb structure of bread and prevent aging. When making bread with refrigerated dough, adding sucrose ester can effectively prevent dough from denaturation during refrigeration.
4. Distilling monoglycerides
Its main function is as a bread tissue softener, which plays an anti-aging and fresh-keeping role in bread. It is often used in conjunction with other emulsifiers to play a synergistic role.
Application of emulsifier in industry;
In the military industry, emulsifiers are often added to explosives to make emulsion bombs. Generally, water-insoluble hydrocarbon fuel is used as the continuous phase and supersaturated ammonium nitrate solution is used as the dispersed phase. Through the emulsification of emulsifier, ammonium nitrate salt solution is dispersed in hydrocarbon fuel in tiny droplets, forming a special water-in-oil emulsification system.
Because emulsion explosive is a highly unstable and irreversible system in thermodynamics, the function of emulsifier is to greatly reduce the interfacial tension between oil and water and form an interfacial film on the interface, which makes it difficult for ammonium nitrate droplets in the internal phase to coalesce, thus improving the stability of emulsion explosive.
Emulsifiers are used in the flotation of coal slime, metallic ore and nonmetallic ore to improve flotation reagents. In the process of flotation, the emulsion dispersion degree of flotation agent has an important influence on its use efficiency and flotation effect, so the addition of emulsifier is helpful to improve the collection performance of flotation machine and greatly reduce the consumption of flotation agent.
Compared with ordinary diesel oil, micro-emulsified diesel oil prepared by adding emulsifier into the mixed system of water, methanol and diesel oil has better combustion performance, lower energy consumption and less pollution. Adding biodiesel with certain emulsifying ability to petrochemical diesel oil can not only promote the development of renewable energy industry, reduce emissions and improve the environmental protection performance of fuel oil, but also benefit the emulsification of fuel oil, improve the combustion rate and reduce energy consumption.
