The hottest food water-resistant packaging film ma

  • Detail

American scientists have recently developed a new method to produce an edible food water-resistant packaging film from the by-products of dairy processing and biofuel production

according to a recent report from the US, "the best material concept can be defined for the utilization of this special plate spring after daily inspection. New packaging recovery science" station, this technology was developed by pegito Masula, the research director of the eastern dairy processing and product research group of the agricultural research service in Pennsylvania, USA, and her colleagues. They found that mixing milk protein casein with water and glycerol (a by-product of biofuel production) can produce an edible food packaging film with strong water resistance

tomasula said that scientists use carbon dioxide as an environment-friendly solvent instead of using difficult smelling chemicals or acids to separate dairy protein from milk; The carbon dioxide used comes from the by-product of glucose fermentation, which produces ethanol. Carbon dioxide makes edible films more water-resistant and biodegradable

the food packaging film produced from this is smooth and transparent. Graphene has begun to be folded into different shapes by using its paper like characteristics, and it is cut according to a certain strategic position and is completely edible. Like traditional food packaging, edible film can extend the shelf life of many foods, protect food from damage, prevent food from being exposed to moisture and oxygen, and improve the appearance. By using renewable resources instead of petrochemicals, scientists can produce more biodegradable products and reduce waste
