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.
Most of the technological operations for the production of meat products are mechanised and carried out using specially designed equipment, including meat grinders. This paper reviews meat grinders of different design and performance, used in both household and industrial applications. The technical characteristics, construction and operating principle of the meat grinder are described.
The extrusion technique, which combines mixing, shaping, texturing, and heating to create a unique food product, is gaining popularity in the worldwide agro-food processing sector. Extrusion cooking is a high-temperature, short-time (HTST) method that kills bacteria and inactivates enzymes. Compared to conventional cooking, extrusion cooking is favored because of its high productivity and substantial nutrient retention. Extrusion technology has become an essential tool in the food processing industry with its various benefits over other processing methods. It is a low-cost approach that provides a platform for processing a variety of items from several food categories by altering major or minor components and processing conditions. Extrusion technique is used in the food sector to create a wide range of supplemental foods, pet foods, morning cereals, pasta, snacks, and other textured foods. It's a low-cost method of reintroducing food processing waste and by-products into the food supply. Extrusion technology's flexibility allows for the production of value-added products and nutritionally dense fortified goods using various low-cost raw ingredients. Extruded goods are microbiologically safe, have a longer shelf life, and have less moisture content. This technology's advantages include product diversity and excellent quality and new food productivity and low processing time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
