Abstract
The aims of the study were to determine pulp proportion, dried pulp rendement, nutrient dan total phenolic content avocado variety of Ijo Panjang dan Ijo Bundar. Variety of Ijo Panjang and Ijo Bundar were selected because both of varieties were categorized as excelent varities and recomendedto develop in Indonesia. Water, carbohydrate, protein, fat dan ash content were determined by using proxymate analysis (AOAC), vitamin A dan E using spectrophotometry method, vitamin C using titration method, dan minerals using AAS method. Total phenolic content were determined by using Follin-Cialcetau method. The result of the studies found that pulp portion Ijo Bundar Variety higher than Ijo Panjang. Water content dan zinc of Ijo Panjang variety higher than Ijo Bundar. Dried pulp rendement of Ijo Bundar higher than Ijo Panjang. Protein, fat, ash, minerals (Fe, Na, K dan P) avocado variety of Ijo Bundar higher than Ijo Panjang. Magnesium dan mangan content of both varieties have not significant different. Total phenolic content of pulp dan dried pulp were higher in Ijo Bundar than Ijo Bundar.
ABSTRAK
Penelitian ini bertujuan untuk mengetahui proporsi daging buah, rendemen tepung, kandungan gizi dan fenol total alpukat varietas Ijo Panjang dan Ijo Bundar. Pemilihan kedua varietas tersebut karena merupakan varietas unggul dan direkomendasikan untuk dikembangkan di Indonesia. Kandungan, air, karbohidat, protein, lemak dan abu dilakukan dengan analisis proksimat (AOAC), kandungan vitamin A dan E dengan metode spektrofotometri dan vitamin C dengan metode titrasi, analisis mineral dengan metode AAS. Total fenol dianalisis dengan metode Folin-Ciocalteu. Hasil penelitian menunjukan bahwa proporsi daging buah, kadar air, seng varietas Ijo Panjang lebih tinggi dibandingkan Ijo Bundar. Rendemen tepung alpukat lebih tinggi pada varietas Ijo Bundar. Kandungan protein, lemak, abu, vitamin (A,E dan C), mineral (Fe, Na, K, P) lebih tinggi pada varietas Ijo Bundar. Kandungan magnesium dan mangan tidak terdapat perbedaan signifikan kedua varietas. Fenol total daging buah dan tepung alpukat lebih tinggi pada varietas Ijo Bundar dibandingkan Ijo Panjang.
