Q. Which of the following is/are true regarding Milk-Protein based Packaging film?
1) They are available in film form as well as spray form.
2) Starch based edible films are slightly better than Milk-Protein based wrappings.- Published on 01 Sep 16a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
ANSWER: Only 1
- When used in packaging, they could prevent food waste during distribution along the food chain.
- It also does not degrade, creating tonnes of plastic waste that sits in landfills for years. To create an all-around better packaging solution, researchers are developing an environmentally friendly film made of the milk protein casein.
- These casein-based films are up to 500 times better than plastics at keeping oxygen away from food and, because they are derived from milk, are biodegradable, sustainable and edible.
- Some commercially available edible packaging varieties are already available, but these are made of starch, which is more porous and allows oxygen to seep through its microholes.
- The milk-based packaging, however, has smaller pores and can thus create a tighter network that keeps oxygen out.
- In addition to being used as plastic pouches and wraps, this casein coating could be sprayed onto food, such as cereal flakes or bars.
