The Influence Of Freezing On The Occurrence Of Reducing Sugar In The Potato, Leo B. Perssion
Bachelors’ Theses
The purpose or this thesis was to see if the change or potato starch to a reducing sugar in the potato on freezing was due to the freezing itself or to some enzymatic reaction. For we know that reducing sugars are formed in the potato by just freezing, therefore it should be possible to manufacture sugar by using pure potato starch as a base. Although this problem may seem to be an unimportant labor as the supply of sugar is large and the price of sugar cheap; this process of obtaining sugar would save thousands or bushels of potatoes every …

A Study Of Phytosterol Obtained From Cocoa Beans And Cocoa Butter, Norman Anthony Pokorny
Bachelors’ Theses
Despite the fact that considerable work has been done on cholesterol, relatively little is known about its isomer, phytosterol. Both cholesterol and phytosterol belong to the general group of sterols. Cholesterol is described as an aromatic sterol, a mono~atomic secondary alcohol, containing an iso-propyl and a vinyl group, with a terpene-like structure. Cholesterol was first discovered by Conradi in 1775, then by Gren (1788) in biliary calculi. In 1785 Fourcroy isolated cholesterol from gall-stones, one variety of which is composed almost wholly of it, but it was confused with adipocere, until Chevreul (1814) discovered its true nature, when he declared …
