Studies of citron, F. Habtel and A. Kihchnee (Ztschr. Untersuch. Nahr. u. 

 Genussmtl., 22 {1911), No. 6, pp. 350-853). — ^Analyses are reported and dis- 

 cussed of 21 samples of candied citron. In the authors' opinion starch sirup is 

 necessary for the production of a translucent product of good quality. The 

 commercial custom, it is stated, is to use at least 40 parts by weight of starch 

 sirup to 120 of sugar. The authors intend to study the question experimentally 

 with a view to determfning the proportion of starch sirup actually necessary. 



The composition of sauerkraut, E. Fedek (Ztschr. Untcrstich. Nahr. u. Genus-

 reported. 



The use of spices as preservatives, C. Hoffman and Alice C. Evans (Jour. 

 Indus, and Engin. Cheni., 3 (1911), No. 11, pp. 835-838; Jour. Home Econ., 3 

 (1911), No. 5, pp. 452-Jf59). — According to the investigations it appears "that 

 cinnamic aldehyde and eugenol as such possess considerable preservative ac- 

 tion and aid materially in preserving substances to which they are added. 

 Both are contained in such spices as cinnamon and cloves." The authors be- 

 lieve that the marked preservative action of these si^ices noted in their experi- 

 ments must be attributed to their content of these essential oils. "As this 

 preservative action takes place, even when the spices are used in the small 

 quantities necessary fop. flavoring, their use can be recommended in contrast 

 to such spices as pepper and ginger which have been shown to possess but 

 little, if any, preservative action."
