  <name>Citronellal</name>
  <description>Isolated from essential oils, especies citronella oilsand is) also present in citrus peel oil, kumquat peel oil, parsley seed oil, ginger, pepper, cocoa, lovage root and other foods. Production synthetically by hydrogenation of 3,7-Dimethyl-2,6-octadienal &lt;ht&gt;JGH37-H&lt;/ht&gt; or hydrogenation of 3,7-Dimethyl-6-octen-1-ol &lt;ht&gt;JRJ33-M&lt;/ht&gt;. Flavouring ingredient. Citronellal is found in many foods, some of which are cocoa and cocoa products, citrus, wild celery, and lemon grass.</description>
