Propylene glycol is usually slightly sweet, odorless, colorless and transparent Oily liquid, hygroscopic, and easily mixed with water, acetone, and chloroform. Propylene glycol has good viscosity and hygroscopicity, less viscosity, toxicity and irritation than glycerin, and good solubility. Therefore, it is widely used as hygroscopic agent, antifreeze, lubricant and solvent in the food, pharmaceutical and cosmetics industries.
The following propylene glycol supplier will introduce to you the application and advantages of propylene glycol in the food industry:
Propylene glycol has good solubility for food pigments, and adding It is not volatile and cheap, so it is an ideal solvent for food coloring.
Propylene glycol’s emulsifying and moistening properties have been widely used in the manufacture of bread and cakes abroad. In addition, due to its emulsifying properties, bread production time can be shortened. When propylene glycol is added to bread, it easily absorbs moisture in the air, thus preventing bread and cakes from hardening.
Propylene glycol has the ability to sterilize. It can be used as a preservative and sterilizer for canned fruits, jams, pickled products, ham and sausages. Propylene glycol’s moistening and softening properties also prevent staleness in smoked seafood. When the concentration of propylene glycol is above 10%, it can prevent the growth of mold in liquid foods, which is effective for the preservation of packaged foods and syrups on the table.
When producing fresh eggs and thin noodles, adding propylene glycol can prevent the bread from drying out and give it a good gloss. It is also relatively stable and can maintain its freshness for a long period of time.
Since propylene glycol has a higher boiling point and a lower freezing point, it is widely used as a heat transfer medium in dairy production and beer production.
