Abstract

The fragrance of rice was produced by 2-acetyl-1-pyrroline (2AP). It has scent like pandan leaf. That was one of the qualities in eating rice. Thus, fragrance was important to the quality of rice. There are many products of bagged rice products available in department stores, convenience stores or in general markets. Therefore, the objective of this experiment was to test the fragrance of bagged rice sold at department stores or convenience stores, including 14 samples of Jasmine rice, 6 samples of Jasmine brown rice, 1 samples of slightly fragrant rice and 1 sample of non-scented rice. Using electronic nose tools to classify the fragrance of rice, the device recognizes the scent pattern and analyze as similar or different. The results showed that when classifying the fragrance of packaged rice, examples of jasmine rice and jasmine brown rice had different fragrance. Moreover, this experiment was test by man through smell and taste of cooking rice. It was found that the results of man were different the results electronic nose. The sense of man might not classify the different of rice brand. On the other hand, electronic nose could classify clearly.
