CHAPTER I 



THE COMPOSITION OF FRUITS 



For convenience, the composition of the common fruits 

 may be divided into three phases: (1) composition of the 

 tree, (2) composition of the fruits, and (3) the changes in 

 the ripening process and in storage. Unfortunately, there 

 is not as great uniformity of opinion among the chemists 

 in regard to the composition of fruits as might be wished 

 for, yet many experimental data are available and are 

 valua])le for the present purpose. Different chemical 

 methods in analysis and widely varjdng material account 

 in part for the results and therefore for the difference of 

 opinion. While it is not possible here to consider the analysis 

 of all the fruits, some of the more important ones maj'- be 

 used for illustration.
