The reading and lecture are both about casein-based plastic packages. Whereas the author of reading states advantages of this packaging, the the lecturer casts doubts on the main points made in the reading by providing numerous reasons. First of all, according to the author of the passage, casein based packaging can reduce large amount of waste from our environment as these can easily dissolve in water. However, the lecturer disputes this point. He says that casein is extreme durable in water. Therefore, we will need an extra packing to protect the inner layer which will result in polluting environment. Secondly, the reading states that, casein have smaller pores which can help in blocking oxygen molecules and therefore it become more effective in keeping food fresh. Nevertheless, the lecturer refutes the argument. He argues that, its low durability with water result in absorbing water molecules and result in oxidation of food. In addition he points out that this also result in low elasticity of the packaging. Finally, the reading claims that these bags can be nutritious as they contain high number of proteins and other beneficial substances. On the other hand, the lecturer believes that these are big threat for those people who are allergic to milk and other dairy substance. In conclusion, although the reading and lecture are both about the edible milk based packaging, the three main point in the reading are effectively challenged by the lecturer.
