Transcript

  • 1. FATTY ACID PROFILE OF Sterculia sp. SEED OILS AND THEIR POTENTIAL FOR COMMERCIAL USE Chelsea P. Del Rosario Wensette B. Ladion Jake E. Yongco
  • 2. OUTLINE INTRODUCTION Background of the Study Objectives of the Study Significance of the Study Scope and Limitations of the Study MATERIALS AND METHODS RESULTS AND DISCUSSION CONCLUSIONS RECOMMENDATIONS
  • 3. INTRODUCTION Background of the Study Plant oils: useful in health, food applications and in the industrial world
  • 4. great demand of plant oils, few sources available Necessary to find alternative sources of oils
  • 5. Related plants found to have oils used in food and industrial applications Sterculia striata Sterculia foetida
  • 6. What’s new in this study?
  • 7. Objectives of the Study Main objective: to characterize the chemical properties of the oil from the seeds of Sterculia sp. especially its fatty acid profile
  • 8. Ground Seeds Oil Supercritical Fluid Extraction
  • 9. Acid Value Peroxide Value Gas Chromatography
  • 10. VS. Sterculia sp. seed oils Canola oil Coconut oil Palm oil Fatty Acid Profile
  • 11. Significance of the Study determine alternative source of plant oil
  • 12. Scope and Limitations of the Study Sterculia sp. seeds Supercritical Fluid Extraction Gas Chromatography Acid Value, Peroxide Value
  • 13. MATERIALS AND METHODS Sample Preparation 2 Plant Sampling1
  • 14. Identification of Sample 3 Extraction of Oil4
  • 15. Wet method of Analysis (Acid Value,Peroxide Value) 5 Gas Chromatography6 Comparing with other Types of Oils 7
  • 16. RESULTS Sample Preparation Seed samples were found to be 231.2595 grams.
  • 17. Identification of Sample The seed sample was identified to be one of the species of the genus Sterculia.
  • 18. Extraction of Oil Oil I – 1.8449 grams Oil II – 5.7753 grams Oil III – 7.7357 grams
  • 19. Chemical Analysis: Acid Value and Peroxide Value OIL I OIL II OIL III Acid Value 174.73 208.80 185.88 Peroxide Value 2.360 2.780 2.445
  • 20. Chemical Analysis: Gas Chromatography FATTY ACID OIL II (%w/w) OIL III(%w/w) Myristic 0.28 0.29 Palmitic 61.8 59.8 Stearic 4.60 4.81 Oleic 2.97 2.86 Linoleic 29.5 31.3 Linolenic 0.303 0.345 Arachidic 0.568 0.647
  • 21. Comparison with Other Types of Oil FATTY ACID OIL II OIL III PALM OIL COCONUT OIL CANOLA OIL Caproic (C6) ND ND ND 0-0.8 ND Caprylic (C8) ND ND ND 5.0-9.0 ND Capric (C10) ND ND ND 6.0-10.0 ND Lauric (C12) ND ND ND 44.0-52.0 ND Myristic (C14) 0.28 0.29 0.5-2.0 13.0-19.0 ND Palmitic (C16) 61.8 59.8 32.0-45.0 8.0-11.0 4.0 Stearic (C18) 4.60 4.81 2.0-7.0 1.0-3.0 2 Oleic (C18:1) 2.97 2.86 38.0-52.0 5.0-8.0 62 Linoleic (C18:2) 29.5 31.3 5-11 0-1.0 22 Linolenic (C18:3) 0.303 0.345 ND ND 10 Arachidic (C20) 0.568 0.647 ND 0-0.5 ND % w/w
  • 22. Palmitic Acid Content of Different Oils 0 10 20 30 40 50 60 70 OIL II OIL III palm oil coconut oil canola oil %w/w
  • 23. Linoleic Acid Content of Different Oils 0 5 10 15 20 25 30 35 OIL II OIL III palm oil coconut oil canola oil %w/w
  • 24. Stearic Acid Content of Different Oils 0 1 2 3 4 5 6 OIL II OIL III palm oil coconut oil canola oil %w/w
  • 25. CONCLUSION Sterculia sp.(seeds) can be a source of plant oil. This type of oil can be used in many commercial applications.
  • 26. RECOMMENDATION • more comparisons with other types of oil • subject Sterculia sp. to higher pressures and to study further the fatty acids • Other chemical analysis
  • 27. THANK YOU! We are now ready for your questions.
