Odour profiling from decomposition of local food waste
Siti Rohana Mohd Yatim1, Ku Halim Ku Hamid2, Kamariah Noor Ismail3, Zulkifli Abdul Rashid4.
The aim of this study is to investigate odour emission profiles from
storage of local food waste and to assess the potential health risk
caused by exposure to volatile compounds. Food waste
decomposition process was conducted for 14 days and kept at 20°C
and 30°C in self-made bioreactor. VOCs emissions from both samples
were collected at different stages of decomposition starting at day 0,
day 1, day 3, day 5, day 7, day 10, day 12 and day 14. It was analyzed
using TD-GC/MS. Findings showed that various VOCs were released
during decomposition of food waste. Compounds produced were
influenced by time, temperature and the physico-chemical
characteristics of the compounds. The most abundant compound
released was dimethyl disulfide. Potential health risk of exposure to this
compound is represented by hazard ratio, HR, calculated at 1.6 x 1011.
Since HR equal to or less than 1.0 is considered negligible risk, this
indicates that the compound posed a potential risk to human health.
