Glycerol As Plasticizer In Egypt

the effect of glycerol concentration as a plasticizer

The effect of glycerol concentration as a plasticizer

The most widely used type of plasticizer is glycerol (Togas et al. 2017). Various studies have been carried out regarding the making of edible films from hydrocolloid and other gelatin with glycerol as plasticizers. Rusli et al (2017) have conducted research on the manufacture of edible films from carrageenan with glycerol.

Glycerol esters - Plasticisers - Information Center

Glycerol esters These plasticisers (US: plasticizers) are made by modifying the structure of fully hardened castor oil – extracted from the seeds of the castor oil plant – with acetic acid. The resulting acetylated glycerol monoester has a low molecular weight, improving the compatibility and processability of the plasticiser.

Optimization of Plasticizer Glycerol in Edible Film Based

Glycerol is used to regulate the water content in food, preventing drought on food and glycerol as a plasticizer can improve film flexibility. Increasing the amount of glycerol in a water-starch mixture reduces the value of voltage and elongation. Low glycerol content also reduces the tensile strength of edible film.

Preparation and characterization of glycerol plasticized

The addition of plasticizers can improve the flexibility of the pure starch films and glycerol is commonly recognized as one of the most suitable plasticizers (Cervera et al., 2004). Chitosan is also attracting strong research interest as it is nontoxic, biodegradable and biocompatible cationic polysaccharide (Mathew et al., 2006).

Effect of glycerol and sorbitol plasticizers on physical

The most commonly used plasticizers for starch based films are polyols including glycerol, sorbitol etc. Many researchers studied the effect of various polyols on the properties of starch films derived from different sources –. So far, little work is found on the effect of various polyols (glycerol and sorbitol) on sugar palm starch.
