Although citrus processors recover most of the essential oils in the peel, the amount remaining is released as air pollutants and volatile organic compounds (VOCs) during cattle feed manufacturing. Citrus processing plants are required to obtain permits allowing emission of 91 t/year (100 tons/year) of VOCs, an amount exceeded by most processors. The objective of this study was to develop an accurate, on‐site method to measure VOC emissions, accomplished by use of adsorbent traps subsequently analyzed by gas chromatography. Over 90 percent of the oil entering the feed mill was accounted for, with d‐limonene as the major VOC, including other terpenes, β‐pinene and myrcene. Of sampling locations in a typical feed mill, error analysis determined the least precision (16.9%) was associated with determining the input rates of peel to the dryer. The sampling technique developed is a viable method for monitoring VOCs with reproducible results.
