Abstract

Tiga cara ekstraksi minyak kelapa telah dipelajari yairu ektrasi basah (wet rendering).Penggorengan kelapa parut segar,dan penggorengan kelapa parut yang telah dikeringkan.Hasil penelitian menunjukan bahwa adapengaruh nyata terhadap efisiensi ekstrasi,peningkatan asam lemak bebas dan waktu yang diperlukan untuk ekstraksi.Ektrasi dengan cara penggorengan kelapa parut segar lebih efisien dibandingkan dengan penggorengan kelapa parut yang telah kering.Penggunaan minyak goreng juga berpengaruh secara nyata terhadap ketiga parameter diatas.Penggunaan minyak goreng paling sedikitmemberikan efisiensi paling tinggi namun peningkatan asam lemak juga tinggi.

Abstract

A study on isothermic-sortion characteristics of some desccated coconut had been conducted.The desiccated coconut was made from hybrid coconuts,khina-1,khina-2 ,khina-3.The result showed that the moisture content equilibrium range of dessicated coconut made from khina-1,khina -2,and khina-3was respectively 2.42-10.43%(db),2.27-13.66%(db)and 2.47-11.49%(db)due to adsorbtion approach,whereas by desortion it was 22.66-46.94%(db),3749-57.56%(db)43.95-62.97%(db).The reseach proved thet Henderson Equation was the most suitable to describe the isothermic-sorption models of desiccated coconut made from those hybrid coconuts.By knowing the moisture content equilibrium and isothermic-sorptionmodels of those desiccated coconuts,the storage condition to maintain the quality required can be designed.
