Natural Pineapple Leaf Fibre Extraction On Josapine And Morris

Abstract

Abstract. The pineapple's leaf plant contains approximately 2.5% to 3.5% of strong white silky fibres. These fibres are useful and can be extracted from the leaves. There are a few ways to extract the fibre such as hand scrapping and by extraction machine. The objective of this research is to study the quality of fibre extraction by using different age of pineapple leaf. Next, the study aims to compare the quality of Josapine and Morris pineapple leaf with tensile test. Fibre yield percentage are calculated to determine which type of pineapple leaf produce high production of dry fibre. The mechanical properties of the fibres are analysed by Tensile Test under American Standard Testing Methods (ASTM C1577-03) and Scanning Electron Microscope (SEM). The result of the fibre yield percentage show the Josapine type on 12 month ages are the highest value fibre yield percentage which is 7.89%. Based on fibre yield percentages, it showed the Josapine type produce better dry fibre production compare to Morris type. Based on mechanical test, it showed Josapine type on 12 months ages are the strongest fibre compare to Morris type since it can withstand on 67.6 N of load.

Varietal Discrimination of Pineapple (<i>Ananas comosus</i> L.) Using Chromatographic Fingerprints and Chemometrics

“…Epicatechin, however, showed a higher amount in MD2 varieties than in other varieties. [20]. Even though the similarities and differences among the three varieties of pineapple can be observed in the chromatographic fingerprints obtained, a more systematic approach in varietal discrimination was further evaluated using chemometric techniques as this approach will help to discriminate even the slightest variation of bioactive compounds [21].…”
