EXERCISE 29 

 A STUDY OF RYE 



Object. To study samples of rye with reference to their 

 quality and commercial grade, and to become familiar with 

 different grades of rye. 



Explanation. Rye is used for the production of flour for 

 bread, for malting purposes, and to some extent for feed for 

 live stock. Rye is not extensively grown in the United 

 States. There are not as many varieties of rye as of wheat. 

 There is a variation in texture and color, but it is not as im- 

 portant as in wheat. There is usually but one class of rye 

 recognized on the commercial market. Different grades of 

 rye are recognized, and the commercial grade given depends 

 upon the quality. The student should become familiar with 

 the different factors that affect the quality of rye. Repre- 

 sentative samples of different grades of rye are used in this 

 study. 



Equipment. 1. Four ten-pound samples of rye. 



2. A weight-per-bushel tester. 



3. A balance weighing to one half gram. 



Directions. Weigh out twenty grams of rye from one of 

 the samples and make a careful study of it. Use the ac- 

 companying outline form "A Study of Rye," to record the 

 results of the examination.
