Pengaruh Konsentrasi Natrium Metabisulfit (Na2S2O5) dan Suhu Pengeringan terhadap Mutu Pati Biji Alpukat (Persea americana Mill.)

Abstract

The aim of this research was to investigate the effect of Na,S,O, and drying temperature on the quality of avocado seed starch that produced. The research had been performed using factorial completely randomized design (CDR) with two factors, ie: natrium metabisulfite concentrates (Ki 0 ppm, K2 750 ppm, K 1500 ppm, K₁ = 2250 ppm. K, 3000 ppm) and drying temperature (S= 50°C, S₂ = 60°C. S=70°C), Parameters analyzed were yield, water content, ash content, sulfite residue, and organoleptic color

Natrium metabisulfite concentrates had highly significant effect on yield, ash content, sulfite residue and organoleptic color, and had no significant effect on water content Drying temperature had highly significant effect on yield, water content, ash content, sulfite residue, organoleptic color. The interaction of natrium metabisulfite and drying temperature had highly significant effect on yield, ash content, and sulfite residue, and had no significant effect on water content and organoleptic color. The 3000 ppm natrium metabisulfite and the 50°C drying temperature produced the best quality of the avocado seed starch
