Physichochemical properties of Kebumen Entog Dwarf coconut

Abstract

Kebumen Entog Dwarf coconut is one of the superior coconut varieties with characteristics of early bearing, large fruit size and sweet water. The study was conducted to determine the physicochemical properties of fruit and water of Kebumen Entog Dwarf coconut. Evaluation was carried out to measure the mineral content of coconut water, water content, ash, protein, and fat, the content of fatty acids and amino acids of fruit flesh. The fruits of Nias Yellow Dwarf, Mapanget Tall, Tenga Tall and KHINA-1 Hybrid were also evaluated. The analysis was carried out at the Laboratory of PT. Saraswati Indo Genetech, Bogor. The results showed that potassium and phosphorus content in water of young nut of Kebumen Entog Dwarf coconut fruit were higher than these in Nias Yellow Dwarf. The young kernel contained of 49.52% fat, 3.94% moisture, 3.78% ash, and 7.64% protein. The mature kernel of Kebumen Entog Dwarf contained of 63.20% fat, 5.9% moisture, 1.72% ash, and 5.24% protein. The medium chain fatty acids (caproic, caprilic, capric and lauric acids) in young and mature nuts was 43.12% and 51.07%, respectively. Fifteen types of amino acids in kernel of mature kernel was also detected. Dominant amino acids in coconut flesh were glutamic acid (1.28%), arginine (0.71%) and aspartic acid 0.45%.
