But lignin, and in part cellulose, is susceptible to oxidation — meaning it readily picks up extra oxygen molecules, and those molecules alter the polymer's structure. The added oxygen molecules break the bonds that hold those alcohol subunits together, creating molecular regions called chromophores.

In the case of lignin oxidation, that color is yellow or brown. Oxidation is also responsible for a sliced apple browning when it's abandoned on the kitchen counter. Typically, paper manufacturers try to remove as much lignin as possible by using a bleaching process, according to Richardson. The more lignin that's removed, the longer the paper will remain white.

Cellulose is the most abundant organic material in nature. It is also technically colorless and reflects light extremely well rather than absorbs it which makes it opaque ; therefore humans see cellulose as white. However, cellulose is also somewhat susceptible to oxidation, although not nearly as much as lignin.

Oxidation causes a loss of electron s and weakens the material. In the case of cellulose, this can result in some light being absorbed, making the material in this case, wood pulp appear duller and less white some describe it as "warmer" , but this isn't what causes the bulk of the yellowing in aged paper.

Lignin is the other prominent substance found in paper, newspaper in particular. Lignin is a compound found in wood that actually makes the wood stronger and harder. In fact, according to Dr. Hou-Min Chang of N. State University in Raleigh, "Without lignin, a tree could only grow to about 6 ft.

Lignin is also highly susceptible to oxidation. Exposure to oxygen especially when combined with sunlight alters the molecular structure of lignin, causing a change in how the compound absorbs and reflects light, resulting in the substance containing oxidized lignin turning a yellow-brown color in the human visual spectrum.

Since the paper used in newspapers tends to be made with a less intensive and more cost-efficient process since a lot of the wood pulp paper is needed , there tends to be significantly more lignin in newspapers than in, say, paper made for books, where a bleaching process is used to remove much of the lignin. The net result is that, as newspapers get older and are exposed to more oxygen, they turn a yellowish-brown color relatively quickly.

Advertisement As for books, since the paper used tends to be higher grade among other things, meaning more lignin is removed along with a much more intensive bleaching process , the discolorization doesn't happen as quickly.
