Degradable chewing gum 04/04/2014

More news on this interesting topic have been published by confectionery news.com (see link).

Wrigley has filed a patent describing a new degradable gum. The way this is achieved is by formulating the gum base with “block polymers”. The company claims that the resulting product is more easily removed from surfaces such as sidewalks (in 20 seconds a high pressure hot water jet can remove more than 80% of the material)

According to wikipedia:

“Block copolymers comprise two or more homopolymer subunits linked by covalent bonds (4). The union of the homopolymer subunits may require an intermediate non-repeating subunit, known as a junction block. Block copolymers with two or three distinct blocks are called diblock copolymers and triblock copolymers, respectively.”

In this particular patent, the company uses polymers of at least 4 blocks composed of at east 2 different monomer systems.

The articles from confectionerynews.com mentions as well other companies that presented progresses on this controversial field of the chewing gum business (Mondelez, Revolymer, TNO, RSSL,  GumLink, Fertin Pharma, University College Cork) . I also posted in the past about those patents and inventions.

 

 

Biodegradable gum 20/04/2013

Now it’s been a while since I last posted about biodegradable gum.

So for those of you interested on the subject, here is a link to confectionerynews.com which informs about a new patent being filed by Mondelez on this matter.

As you know, this is a hot subject and many companies are working on developing this type of gum which would be more environmentally friendly. There is a product already in the market, Rev7 but it does not seem to really take off. In fact it has been withdrawn from the US market. All the research turn mainly about news types of polymers. There are many polymers which degrade easier than the ones currently in use, but they do not offer an acceptable chewability. So the main task is to find  a polymer with the right degradability and nice chew profile. In this case, the article and the related patent mentions “alternating copolymer of C2-C10 alkene and maleic anhydride”.
