چکیده مقاله
Quality and safety, both in objective product characteristics and subjective consumer perception terms, are essential factors for the success of any food product Therefore, the history of using the packaging goes back to protecting food and foodstuffs in the distant past Shashi K Pankaj et al , 2018 Food packaging is concerned with preserving and protecting all types of foods and their raw materials, mainly from microbial spoilage, and extending their shelf life Therefore, increasing the use of packaging materials, especially synthetic packaging for their excellent gas and liquid barrier characteristics, has led to severe ecological problems due to their total non biodegradability Tharanathan, 2003 Mihalca et al , 2021 Nowadays, one of the synthetic materials produced in different types and applications is plastic and plastic composition, such as plastic packaging films Zhong et al , 2020 Some efforts and awareness by environmentalists about the bio pollution of polymers and the importance of their safety introduce new consumption patterns that include packaging products with biodegradable materials Mirzaei Mohkam et al , 2020 So biodegradable polymers from renewable resources have shown significant potential in packaging applications due to their environmental benefits There are two types of biopolymers; one is a mixture of natural and synthetic plastics, such as a mixture of gelatin and polypropylene films, which destroy partially after some time Another group is films that destroy entirely in the environment, which is named edible biodegradable film Tian et al , 2021 Thus, biopolymers are degradable, renewable resources and made of cheap and readily available raw materials The second category includes animal or plant based proteins, polysaccharide based films like starches, cellulose derivatives, chitosan/chitin, gums, and lipids Mellinas et al , 2016 In designing a package, many factors must be considered Most of these factors depend on the chemical nature of the film, the type of food, and the target microorganism Among the critical factors related to the chemical nature of the packaging film, water vapor permeability, tensility, water solubility, and other factors that vary depending on the chemical nature It is noticeable that the efficiency of edible films is related to their quality indicators transparency and light absorption or their thickness H Chen et al , 2019 For example, compared to polysaccharides and lipids, proteins have some advantages, such as relative abundance, good film forming ability, and high nutritional value, which make proteins be used extensively for preparing biodegradable packaging films like whey protein based, zein based, and gelatin based films Calva Estrada et al , 2019
