The Chemical Constituent analysis of Haustorium of Palmyra Palm in Phetchaburi province

Abstract

The haustorium can be used to produce a wide variety of food products. The objective of this research is to analyze the chemical constituent of the four phases of the haustorium, including the first phase, the cuttings when the length of the cotyledonary petiole about is 23-30 cm without incubation, the second phase, the cuttings of the cotyledonary petiole and incubated for 10 days, the third phase, the cuttings of the cotyledonary petiole and incubated for 20 days, the fourth phase, the cuttings of the cotyledonary petiole and incubated for 30 days and the control haustorium. The results showed that all four phases of haustorium had the following chemical constituent as follows average moisture 73.13-80.02%, protein 4.40-5.49%, fat 0.02-0.08%, fiber 2.83-5.89%, ash 4.51-6.10%, carbohydrate 3.06-13.46%, and firmness 0.60-0.75 N/mm. It was found that the first and second phases contained the moisture, fiber, and ash were higher than the control but protein and carbohydrate content were lower (P> 0.05). Also, the chemical constituent in the third and fourth phases was not significantly different from those of the controls (P> 0.05) except the protein content, and the firmness was lower than the control haustorium. Therefore, in the third phase, the cuttings of the cotyledonary petiole and incubated for 20 days were the closest quality to control. The data obtained will be used for further developments of the seed germination and healthy food products from the haustorium.
