Abstract

To obtain the good quality of International Market Standard and better oil as raw material for rose oil synthetic where as the price of natural rose oil is much higher in price that of synthetic. The fractional distillation process was employed on crude Java Citronella oil grown in Sukabumi and Purwokerto to obtained the oil with international market quality and the oil fraction was used as basic material for rose oil synthesis. It was concluded that due to a high cost of the fractional distillation, it was unable to raise the economic added value of crude oil via quality improvement using this process except when the oil fraction was used as basic material for rose oil synthesis.

Abstract

Tempe merupakan makanan khas Indonesia yang digemari oleh seluruh lapisan masyarakat. Berbagai macam variasi produk olahan tempe telah banyak di jual di pasaran Indonesia, namun masih jarang ditemukan produk olahan tempe dalam bentuk minuman. Salah satu penyebab kurang berkembangnya minuman berbahan baku tempe adalah bau langu yang kurang disukai oleh masyarakat. Tujuan dari penelitian ini adalah membuat minuman berbahan baku tempe dengan penambahan perasa Vanila. Karakteristik Kimia yang diamati adalah stabilitas pH, kandungan lemak, karbohidrat, dan kelarutan isoflavon, dan uji kesukaan. Hasil penelitian menunjukkan kadar protein sebesar 0,3%, Gula pereduksi 0,48%, lemak 0,18%. Hasil penelitian juga menunjukan bahwa nilai pH dan kandungan protein terlarut dalam minuman sari tempe tetap stabil setelah penyimpanan selama satu minggu pada suhu 4⁰C. Uji hedonik menunjukkan penambahan gula 7% (w/v) dan 8% (w/v) memiliki nilai rasa berturut 2,35 (tidak suka) dan 3.15 (biasa), Sedangkan Penambahan vanila sebesar 0,25 % (v/v) dan 0,5 % (v/v) memiliki nilai aroma berturut-turut 2,35 (tidak suka) dan 3,5 (antara biasa dan suka). Dari hasil uji ANOVA didapatkan bahwa tidak ada perbedaan nyata antara aroma susu kedelai komersial dengan aroma minuman sari tempe dengan penambahan vanila sebesar 0,5%.

Abstract

Protein is one of the nutrients needed for man living and growing normally.Nutritive value of protein is determined by its ammount and also by the composition of its amino acid.Lysine is one of the essential amino acids found in various food stuffs.Lysine is sometimes used as an indicator for determination of protein quality.It is due to the fact that lysine sometimes found as a limiting essential amino acid, especially in cereal.It is also caused lysine is themost sensitive amino acid to certain processing treatment such as heating,smoking,frying and also involved in mailliard reaction.Other important reason is that lysine can be determined by chemical analysis, not like other amino acids which have to be determined biologically.
