The Color, Water and Oil Holding Properties and Pasting Viscosities of Arrow Root (Maranta arundinacea L) Flour From Different Accessions and Irradiation Doses

Abstract

Gamma irradiation has been widely used as green method to induce mutations of arrow root plants; therefore, superior cultivars might be obtained. This research was purposed to evaluate the effect of different accessions (a1 (Pulosari – Pandeglang), a2 (Cicadas – Pandeglang), a3 (Cikondang – Pandeglang), a4 (Tamansari – Yogyakarta) and a5 (MN1 – Bogor)) and irradiation doses (b1( 0 Gy), b2 (10 Gy), b3 (20 Gy), b4 (30 Gy), b5 (40 Gy) and b6 (50 Gy) on the properties of arrow root flour produced from irradiated arrowroot plants including color, water and oil holding capacities and also pasting viscosities. Results showed that gamma irradiation on the arrow root plants impacted the color properties of arrow root flour in which higher irradiation dose tended to produce brighter arrow root flour. Higher irradiation dose showed a tendency to produce arrow root flour with low water holding capacity but high oil holding capacity. Irradiation doses did not significantly impact all pasting viscosities (peak viscosity, final viscosity and set back viscosity).
