Study on the preservative properties of glycol on food

Abstract

Propylene glycol (PG) is a substance commonly used in many cosmetic products or as an additive in foods. Food officials in the United States and Europe have stated that oral consumption of this substance is generally safe. However, there is a lot of discussion about PG. Reports of PG poisoning are mostly related to inappropriate intravenous use or accidental overuse by children. Because of its low risk of food poisoning, it is recognized by the Food and Drug Administration (FDA) as a relatively safe substance as a food additive such as frozen desserts, ice cream and frozen foods. This article examines what is oral propylene glycol and why is it used? Also, in the current study, it was tried to answer this question: Is it dangerous for the body or not? It's found that while there have been incidents of intoxication from this material due to the usage of extremely high doses, it is not regarded a harmful or poisonous substance in general.

Insights on production mechanism and industrial applications of renewable propylene glycol

“…Propylene glycol is also present in many condiments, frozen vegetables, dairy products, and bread as preservatives. Recent studies by Bokov et al., (2022) confirm that propylene glycol is not harmful or poisonous to the body when ingested. Although, few incidents of intoxication have been reported due to the consumption of extremely high doses.…”

“…Their results show that propylene glycol and calcium chloride are promising antifreeze from economic and environmental perspectives ( Bartolini et al., 2020 ). Propylene glycol is also used as an antifreeze for aircraft and automotives ( Bokov et al., 2022 ). In Canada, propylene glycol is commonly used to protect the heating, ventilation, and air conditioning (HVAC) systems from freezing due to extreme weathers.…”

“…Propylene glycol is a beneficial chemical found in a variety of pharmaceutical and health-care products. Often used to retain moisture and prevent the dryness of skin in alcohol-based hand sanitizers ( Bokov et al., 2022 ). It is a promising solvent in several oral and injectable drugs ( Bokov et al., 2022 ).…”

“…Often used to retain moisture and prevent the dryness of skin in alcohol-based hand sanitizers ( Bokov et al., 2022 ). It is a promising solvent in several oral and injectable drugs ( Bokov et al., 2022 ). Drugs have to penetrate into the deeper skin layers or permeate the skin for effective action.…”
