Application Notes
|
|
Food manufacturing industry
|
Winemaking: Glycerin is used in wine as a taste improver, sweetener, and de-bittering agent. Appropriate addition can enhance the aroma, sweetness, and richness of the wine.
Meat product production: Adding glycerin as a humectant to dried meat, sausages, and cured meat makes the product texture soft and improves the tenderness of the meat.
|
|
Beverage industry
|
Fruit juices and soft drinks: Glycerin can be used in fruit juices, fruit vinegars and other beverages to quickly break down the bitter and astringent taste in the juices and vinegars, and improve the juice's own richness and aroma, bright appearance and sweet and sour taste.
|
|
Baking industry
|
Pastries and cakes: Glycerin is used in bread, cakes and other products as a moisture-retaining agent. It has strong hygroscopic properties, maintains a soft texture and increases shelf life.
|
|
Pharmaceutical manufacturing
|
Glycerin is used in a variety of pharmaceutical formulations, including oral, ophthalmic, parenteral, and topical formulations .
|
|
Daily chemical industry
|
Moisturizer: Glycerin can draw moisture from the air to hydrate the skin, and it can also lock in the moisture in the skin to prevent moisture loss.
Repairing effects: Glycerin assists in skin healing, reduces the occurrence of related dermatitis, and repairs the skin's normal natural barrier function.
