A comparative study on the soil mineral content, weather condition, and flavor profile of roasted pili nuts (canarium ovatum) from different locations
The Canarium ovatum or more commonly known as the pili nut can be harvested from a pili tree that is native to the Philippines (Pham, & Dumandan, 2015). Despite being an indigenous plant in the Philippines, only few studies have been conducted on pili nut. In this research, the researchers putat...

| Summary: | The Canarium ovatum or more commonly known as the pili nut can be harvested from a pili tree that is native to the Philippines (Pham, & Dumandan, 2015). Despite being an indigenous plant in the Philippines, only few studies have been conducted on pili nut. In this research, the researchers putatively identified volatile components of Philippine roasted pili nuts using headspace analysis-gas chromatography-mass spectrometry, investigated the difference of the putatively identified compounds of Philippine roasted pili nuts and the soil mineral conditions depending on location through principal component analysis, and analyzed weather conditions such as dry bulb, rainfall, and relative humidity through univariate analysis of variance (ANOVA). Putative identification of compounds from Bicol, Samar, and Quezon Pili nuts through Headspace GC-MS showed 38 peaks with 21 putatively identified compounds and 17 unknown compounds and were clustered separately based on PCA. Results also revealed that the soil minerals Na, K, Mg, and Ca were significantly different across the three locations. As for the weather parameters, the average relative humidity and dry bulb temperature varied between the three locations, whereas the amount of precipitation did not differ significantly between Bicol, Samar, and Quezon Province. |
